当UITextFiled和UITextView这种文本输入类控件成为第一响应者时，弹出的键盘由他们的一个UIView类的inputView属性来控制，当inputView为nil时会弹出系统的键盘，想要弹出自定义的键盘，将我们自定义的UIView对象给inputView属性赋值即可。表情键盘重点在于排列各个表情和删除键，以及表情键盘上的各种回调设置；

下面为键盘预览图，兼容了竖屏各版本适配，横屏没有兼顾。横屏适配参见这篇博客iOS之自定义表情键盘

图1为6的常用表情，图2为6的全部表情，图3为5的全部表情，表情个数统一为7列3排，根据屏幕不同修改间距以及键盘高度；

下面为项目结构图：采用MVC模式，View层提供表情键盘以及自定义的UITextView。Model层提供表情数据。我为了简单就直接把聊天工具栏通过storyboard拖到了VC上，这里应该再封装一个toolView的；

1、首先来弄好数据层FaceManager，具有一个单例方法、声明了三个数组属性来存放不同的表情；表情图片由Face文件夹来提供；

AllFaces通过我一个名为“emoticons”的plist文件来获取，里面存放的是一个个表情字典，对应着Face中的图片名和图片文字描述；

RecentlyFaces是最近使用过的图片，从本地获取；BigFaces是用来扩展其他大型以及动态效果表情的，没有实现

 1 @interface FacesManager : NSObject
 2 
 3 @property (nonatomic, strong, readonly)NSArray * RecentlyFaces;
 4 @property (nonatomic, strong, readonly)NSArray * AllFaces;
 5 @property (nonatomic, strong, readonly)NSArray * BigFaces;
 6 
 7 + (instancetype)share;
 8 - (void)fetchRecentlyFaces;
 9 @end
10 
11 #import "FacesManager.h"
12 
13 @implementation FacesManager
14 
15 +(instancetype)share
16 {
17     static FacesManager * m = nil;
18     static dispatch_once_t onceToken;
19     dispatch_once(&onceToken, ^{
20         m = [[FacesManager alloc] init];
21     });
22     return m ;
23 }
24 
25 - (instancetype)init
26 {
27     self = [super init];
28     if (self) {
29         [self fetchAllFaces];
30         [self fetchBigFaces];
31     }
32     return self;
33 }
34 
35 - (void)fetchAllFaces
36 {
37     NSString * path = [[NSBundle mainBundle] pathForResource:@"emoticons" ofType:@"plist"];
38     NSArray * arrFace = [NSArray arrayWithContentsOfFile:path];
39     _AllFaces = arrFace;
40 }
41 
42 - (void)fetchRecentlyFaces
43 {
44     NSUserDefaults * defauls = [NSUserDefaults standardUserDefaults];
45     NSArray * arrFace = [defauls objectForKey:@"RecentlyFaces"];
46     _RecentlyFaces = arrFace;
47 }
48 
49 - (void)fetchBigFaces
50 {
51     
52 }
53 
54 @end

2、数据层弄好后，实现关键的FaceKeyBoardView；首先在这个view上我们需要向外发送：点击每个表情、发送键、删除键的事件，所以需要提供三个向外的回调接口：点击表情的回调、点击删除的回调、点击发送的回调；然后再分析视图结构，首先view上部贴了一个ScrollView用来滑动显示每一页表情、一个稍微靠下的的pageController用于显示当前页数、以及底部的toolBar；

FaceKeyBoardView.h

define了几个需要用到的参数。设置了三个回调接口；

 1 #import <UIKit/UIKit.h>
 2 #define GrayColor [UIColor colorWithRed:231 / 255.0 green:231 / 255.0 blue:231 / 255.0 alpha:1]
 3 #define ScreenWidth [UIScreen mainScreen].bounds.size.width
 4 #define ScreenHeight [UIScreen mainScreen].bounds.size.height
 5 #define ToolBarHeight 40
 6 
 7 typedef void (^FaceKeyBoardBlock)(NSString * faceName,NSInteger faceTag);
 8 typedef void (^FaceKeyBoardSendBlock)(void);
 9 typedef void (^FaceKeyBoardDeleteBlock)(void);
10 
11 @interface FaceKeyBoardView : UIView
12 
13 - (void)setFaceKeyBoardBlock:(FaceKeyBoardBlock)block;
14 - (void)setFaceKeyBoardSendBlock:(FaceKeyBoardSendBlock)block;
15 - (void)setFaceKeyBoardDeleteBlock:(FaceKeyBoardDeleteBlock)block;
16 @end

View Code

FaceKeyBoardView.m：

用到的属性：

 1 @interface FaceKeyBoardView ()<UIScrollViewDelegate>
 2 
 3 {
 4     CGFloat _FKBViewH;
 5 }
 6 
 7 @property (nonatomic, strong)NSArray * arrFace;
 8 @property (nonatomic, strong)UIScrollView * scFace;
 9 @property (nonatomic, strong)FaceKeyBoardBlock block;
10 @property (nonatomic, strong)FaceKeyBoardSendBlock sendBlock;
11 @property (nonatomic, strong)FaceKeyBoardDeleteBlock deleteBlock;
12 @property (nonatomic, strong)UIToolbar * toolBar;
13 @property (nonatomic, strong)UIPageControl * pageC;
14 
15 @property (nonatomic, strong)FacesManager * FManager;
16 
17 @end

View Code

a、首先来重写view的init方法，在这里面设定好view的frame以及设定view的子控件。由于屏幕尺寸不同，所以表情竖直方向间距不同，就会影响到表情键盘的高度，所以frame是动态计算出来的；然后再loadview方法中初始化facemanager用来提供数据，以及获得全部表情和设置toolBar；

 1 - (instancetype)init
 2 {
 3     self = [super init];
 4     if (self) {
 5         [self setViewFrame];
 6         [self loadKeyBoardView];
 7     }
 8     return self;
 9 }
10 
11 - (void)setViewFrame
12 {
13     CGFloat marginY = (ScreenWidth - 7 * 30) / (7 + 1);
14     CGFloat scViewH = 3 * (30 + marginY) + marginY*2 + 10;
15     _FKBViewH = scViewH + ToolBarHeight;
16     self.frame = CGRectMake(0, ScreenHeight - _FKBViewH, ScreenWidth, _FKBViewH);
17 }
18 
19 - (void)loadKeyBoardView
20 {
21     //初始化manager
22     self.FManager = [FacesManager share];
23     //获取数据
24     [self fetchAllFaces];
25     //设置toolBar
26     [self setToolBar];
27 }

View Code

b、设置了三个方法来获取不同的表情数据用于显示不同的表情键盘；第一次时默认执行fetchAllFaces；

 1 - (void)fetchRecentlyFaces
 2 {
 3     //更新manager
 4     [self.FManager fetchRecentlyFaces];
 5     self.arrFace = self.FManager.RecentlyFaces;
 6     [self setFaceFrame];
 7 }
 8 
 9 - (void)fetchAllFaces
10 {
11     self.arrFace = self.FManager.AllFaces;
12     //设置表情scrollView
13     [self setFaceFrame];
14 }
15 
16 - (void)fetchBigFaces
17 {
18     self.arrFace = nil;
19     [self setFaceFrame];
20 }

View Code

c、在setFaceFrame方法中设置scrollView以及pageController；我通过表情数量来循环设置每个表情按钮的位置，固定了7列三行，根据屏幕设置不同的间距，在每一页的右下角设置删除按钮。根据页数来设置scrollView的内容宽度以及pageController的页数；

 1 - (void)setFaceFrame
 2 {
 3     //列数
 4     NSInteger colFaces = 7;
 5     //行数
 6     NSInteger rowFaces = 3;
 7     //设置face按钮frame
 8     CGFloat FaceW = 30;
 9     CGFloat FaceH = 30;
10     CGFloat marginX = (ScreenWidth - colFaces * FaceW) / (colFaces + 1);
11     CGFloat marginY = marginX;
12     NSLog(@"%lf",marginX);
13     
14     //表情数量
15     NSInteger FaceCount = self.arrFace.count;
16     //每页表情数和scrollView页数；
17     NSInteger PageFaceCount = colFaces * rowFaces ;
18     NSInteger SCPages = FaceCount / PageFaceCount + 1;
19 
20     CGFloat scViewH = rowFaces * (FaceH + marginY) + marginY*2 + 10;
21     //初始化scrollView
22     self.scFace = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, ScreenWidth, scViewH)];
23     self.scFace.contentSize = CGSizeMake(ScreenWidth * SCPages, scViewH);
24     self.scFace.pagingEnabled = YES;
25     self.scFace.bounces = NO;
26     self.scFace.delegate = self;
27     [self addSubview:self.scFace];
28     //初始化贴在sc上的view
29     UIView * BtnView = [[UIView alloc] init];
30     BtnView.frame = CGRectMake(0, 0, ScreenWidth * SCPages, scViewH);
31     [BtnView setBackgroundColor:GrayColor];
32     [self.scFace addSubview:BtnView];
33     
34     for (NSInteger i = 0; i < FaceCount + SCPages; i ++)
35     {
36         //当前页数
37         NSInteger currentPage = i / PageFaceCount;
38         //当前行
39         NSInteger rowIndex = i / colFaces - (currentPage * rowFaces);
40         //当前列
41         NSInteger colIndex = i % colFaces;
42         
43         //viewW * currentPage换页
44         CGFloat btnX = marginX + colIndex * (FaceW + marginX) + ScreenWidth * currentPage;
45         CGFloat btnY = rowIndex * (marginY + FaceH) + marginY;
46         if ((i - (currentPage + 1) * (PageFaceCount - 1) == currentPage || i == FaceCount + SCPages - 1) && self.arrFace)
47         {
48             //创建删除按钮
49             CGFloat btnDelteX = (currentPage + 1) * ScreenWidth - (marginX + FaceW);
50             CGFloat btnDelteY = 2 * (FaceH + marginY) +marginY;
51             
52             UIButton * btnDelte = [UIButton buttonWithType:UIButtonTypeSystem];
53             btnDelte.frame = CGRectMake(btnDelteX, btnDelteY, FaceW, FaceH);
54             [btnDelte setBackgroundImage:[UIImage imageNamed:@"icon_delete-2"] forState:UIControlStateNormal];
55             [btnDelte setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
56             btnDelte.titleLabel.font = [UIFont boldSystemFontOfSize:15];
57             
58             [btnDelte addTarget:self action:@selector(tapDeleteBtn) forControlEvents:UIControlEventTouchUpInside];
59             
60             [BtnView addSubview:btnDelte];
61         }
62         else
63         {
64         //创建face按钮
65         UIButton * btn = [[UIButton alloc] init];
66         btn.frame = CGRectMake(btnX , btnY, FaceW, FaceH);
67         //tga
68         btn.tag = i - currentPage;
69         //按钮回调；
70         [btn addTarget:self action:@selector(tapFaceBtnWithButton:) forControlEvents:UIControlEventTouchUpInside];
71         NSString * strIMG = self.arrFace[i - currentPage][@"png"];
72         [btn setImage:[UIImage imageNamed:strIMG] forState:UIControlStateNormal];
73         [BtnView addSubview:btn];
74         }
75     }
76     
77     //创建pageController
78     CGFloat pageH = 10;
79     CGFloat pageW = ScreenWidth;
80     CGFloat pageX = 0;
81     CGFloat pageY = scViewH - pageH - marginY;
82     self.pageC = [[UIPageControl alloc] initWithFrame:CGRectMake(pageX, pageY, pageW, pageH)];
83     self.pageC.numberOfPages = SCPages;
84     self.pageC.currentPage = 0;
85     self.pageC.pageIndicatorTintColor = [UIColor lightGrayColor];
86     self.pageC.currentPageIndicatorTintColor = [UIColor grayColor];
87     [self addSubview:self.pageC];
88 }

b、还需要把c中的各种点击事件和scrollView的代理事件实现
点击表情的事件中我执行了2个操作：1、将点击的表情存到本地常用表情数组中，逻辑为，如果数组中已有这个表情，就将此表情移到最前面，没有就将表情插入到数组第一位。这里我想着数据量不是很大就使用了Preference来存放本地；2、将表情的文字描述和表情按钮的tga通过block传出去；

当scrollView翻动时，让pageController的当前页数跟着变化；点击删除发送回调；

 1 //点击表情
 2 - (void)tapFaceBtnWithButton:(UIButton *)button
 3 {
 4     //将表情存储为常用表情
 5     NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
 6     NSMutableArray * arrFaces = (NSMutableArray *)[defaults objectForKey:@"RecentlyFaces"];
 7     
 8     if (!arrFaces)
 9     {
10         arrFaces = [NSMutableArray array];
11         NSDictionary * dicFace = @{@"png":self.arrFace[button.tag][@"png"],@"faceTag":@(button.tag),@"chs":self.arrFace[button.tag][@"chs"]};
12         [arrFaces addObject:dicFace];
13         [defaults setObject:arrFaces forKey:@"RecentlyFaces"];
14         [defaults synchronize];
15     }
16     //NSLog(@"%p",arrFaces);
17     else
18     {
19         //需要新建一个可变数组，不然修改数组会报错。
20         NSMutableArray * arrM = [NSMutableArray arrayWithArray:arrFaces];
21         BOOL isHaveSameFace = NO;
22         for (NSDictionary * dic in arrFaces)
23         {
24             //NSLog(@"%ld--%ld",button.tag,[dic[@"faceTag"] integerValue]);
25             NSString * strFace = self.arrFace[button.tag][@"chs"];
26             NSString * strFaceDic = dic[@"chs"];
27             if ([strFace isEqualToString:strFaceDic])
28             {
29                 [arrM removeObject:dic];
30                 NSLog(@"%@",dic);
31                 //后添加的排在前面；
32                 [arrM insertObject:dic atIndex:0];
33                 isHaveSameFace = YES;
34             }
35         }
36         if (!isHaveSameFace)
37         {
38             NSDictionary * dicFace = @{@"png":self.arrFace[button.tag][@"png"],@"faceTag":@(button.tag),@"chs":self.arrFace[button.tag][@"chs"]};
39             [arrM insertObject:dicFace atIndex:0];
40         }
41         [defaults setObject:arrM forKey:@"RecentlyFaces"];
42         [defaults synchronize];
43     }
44     //block传值
45     self.block(self.arrFace[button.tag][@"chs"],button.tag);
46 }
47 
48 //点击删除
49 - (void)tapDeleteBtn
50 {
51     self.deleteBlock();
52 }
53 
54 -(void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset
55 {
56     self.pageC.currentPage = targetContentOffset->x / ScreenWidth;
57 }

View Code

d、设置toolBar、然后将各个按钮的点击事件实现：

 1 - (void)setToolBar
 2 {
 3     self.toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.scFace.frame.size.height, ScreenWidth, ToolBarHeight)];
 4     self.toolBar.backgroundColor = GrayColor;
 5 
 6     [self addSubview:self.toolBar];
 7     UIBarButtonItem * spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
 8     UIBarButtonItem * recentlyFaceItem = [[UIBarButtonItem alloc] initWithTitle:@"最近表情" style:UIBarButtonItemStylePlain target:self action:@selector(tapRecentlyFaceBtn)];
 9     UIBarButtonItem * normalFaceItem = [[UIBarButtonItem alloc] initWithTitle:@"普通" style:UIBarButtonItemStylePlain target:self action:@selector(tapNormalFaceBtn)];
10     UIBarButtonItem * bigFaceItem = [[UIBarButtonItem alloc] initWithTitle:@"大表情" style:UIBarButtonItemStylePlain target:self action:@selector(tapBigFaceBtn)];
11     UIBarButtonItem * sendItem = [[UIBarButtonItem alloc] initWithTitle:@"发送" style:UIBarButtonItemStylePlain target:self action:@selector(tapSendBtn)];
12 
13     [self.toolBar setItems:[NSArray arrayWithObjects:recentlyFaceItem,spaceItem,normalFaceItem,spaceItem,bigFaceItem,spaceItem,sendItem, nil]];
14 }
15 
16 
17 //点击ToolBar上的按钮回调
18 - (void)tapRecentlyFaceBtn
19 {
20     [self fetchRecentlyFaces];
21 }
22 - (void)tapSendBtn
23 {
24     self.sendBlock();
25 }
26 - (void)tapBigFaceBtn{
27     [self fetchBigFaces];
28 }
29 - (void)tapNormalFaceBtn
30 {
31     [self fetchAllFaces];
32 }

View Code

e、还要实现三个设置回调接口的方法、此时faceKeyBoardView中的方法都实现了；

 1 //点击表情接口
 2 - (void)setFaceKeyBoardBlock:(FaceKeyBoardBlock)block
 3 {
 4     self.block = block;
 5 }
 6 //发送接口
 7 -(void)setFaceKeyBoardSendBlock:(FaceKeyBoardSendBlock)block
 8 {
 9     self.sendBlock = block;
10 }
11 //删除接口
12 -(void)setFaceKeyBoardDeleteBlock:(FaceKeyBoardDeleteBlock)block
13 {
14     self.deleteBlock = block;
15 }

View Code

3、自定义一个UITextView、也可以使用UITextFiledView

.h:具有一个发送回调以及切换键盘状态的方法：

1 #import "XQGTextView.h"
2 #import "FaceKeyBoardView.h"
3 
4 @interface XQGTextView ()
5 
6 @property (nonatomic, strong)FaceKeyBoardView * viewFaceKB;
7 @property (nonatomic, strong)SendBlock block;
8 @end

View Code

.m:实现方法以及初始化表情键盘，在faceKeyBoard发送回调和删除回调中实现需要做的事；

 1 @implementation XQGTextView
 2 
 3 - (instancetype)initWithFrame:(CGRect)frame
 4 {
 5     self = [super initWithFrame:frame];
 6     if (self) {
 7         [self loadFaceKeyBoardView];
 8     }
 9     return self;
10 }
11 
12 - (void)awakeFromNib
13 {
14     [self loadFaceKeyBoardView];
15 }
16 
17 - (void)loadFaceKeyBoardView
18 {
19     self.viewFaceKB = [[FaceKeyBoardView alloc] init];
20     
21     __weak __block XQGTextView * copy_self = self;
22     
23     [self.viewFaceKB setFaceKeyBoardBlock:^(NSString *faceName, NSInteger faceTag) {
24         copy_self.text = [copy_self.text stringByAppendingString:faceName];
25     }];
26     
27     [self.viewFaceKB setFaceKeyBoardSendBlock:^{
28         copy_self.block();
29         //清空textview
30         copy_self.text = nil;
31     }];
32     [self.viewFaceKB setFaceKeyBoardDeleteBlock:^{
33         NSMutableString * string = [[NSMutableString alloc] initWithString:copy_self.text];
34         [string deleteCharactersInRange:NSMakeRange(copy_self.text.length - 1, 1)];
35         copy_self.text = string;
36     }];
37 }
38 
39 -(void)changeKeyBoard
40 {
41     if (self.inputView != nil)
42     {
43         self.inputView = nil;
44         [self reloadInputViews];
45     }
46     else
47     {
48         self.inputView = self.viewFaceKB;
49         [self reloadInputViews];
50     }
51 }
52 
53 - (void)setFaceKeyBoard
54 {
55     self.inputView = self.viewFaceKB;
56 }
57 
58 - (void)setSendBlock:(SendBlock)block
59 {
60     self.block = block;
61 }
62 
63 @end

4、在VC中进行操作：

a、在storyBoard中构建聊天工具栏：将textView绑定为我自定义的textView；

技术分享

b、在发送回调中进行发送消息，利用正则表达式解析出表情发送图文混排的消息；以及聊天工具栏跟随键盘高度变化而变化的设置等；点击表情按钮弹出表情键盘，键盘切换；代码中都有详细描述；

.m:

  1 #import "MainViewController.h"
  2 #import "XQGTextView.h"
  3 
  4 @interface MainViewController ()<UITextViewDelegate>
  5 
  6 @property (weak, nonatomic) IBOutlet XQGTextView *viewText;
  7 @property (weak, nonatomic) IBOutlet UIView *viewChatToolBar;
  8 @property (weak, nonatomic) IBOutlet UILabel *lalText;
  9 
 10 @end
 11 
 12 @implementation MainViewController
 13 
 14 - (void)viewDidLoad {
 15     [super viewDidLoad];
 16     //清空常用表情
 17 //    NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
 18 //    NSMutableArray * arrFaces = [defaults objectForKey:@"RecentlyFaces"];
 19 //    arrFaces = nil;
 20 //    [defaults setObject:arrFaces forKey:@"RecentlyFaces"];
 21     
 22     self.viewText.delegate = self;
 23     //发送回调
 24     [self.viewText setSendBlock:^{
 25         [self sendPictureAndText];
 26     }];
 27     //监听键盘弹出的通知
 28     NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
 29     [center addObserver:self selector:@selector(KeyBoardWillChangeFrame:) name:UIKeyboardWillChangeFrameNotification object:nil];
 30 }
 31 
 32 //发送图文
 33 - (void)sendPictureAndText
 34 {
 35     //正则表达式取出表情
 36     NSString * str = self.viewText.text;
 37     NSMutableAttributedString * strAtt = [[NSMutableAttributedString alloc] initWithString:str];
 38     //创建匹配正则表达式类型描述模板
 39     NSString * pattern = @"\\[[a-zA-Z0-9\\u4e00-\\u9fa5]+\\]";
 40     //依据正则表达式创建匹配对象
 41     NSError * error = nil;
 42     //CaseInsensitive
 43     NSRegularExpression * regular = [NSRegularExpression regularExpressionWithPattern:pattern options:NSRegularExpressionCaseInsensitive error:&error];
 44     if (regular == nil)
 45     {
 46         NSLog(@"正则创建失败");
 47         NSLog(@"%@",error.localizedDescription);
 48         return;
 49     }
