一、简单介绍

xib和storyboard的比较,一个轻量级一个重量级。

共同点:

都用来描述软件界面

都用Interface Builder工具来编辑

不同点:

Xib是轻量级的,用来描述局部的UI界面

Storyboard是重量级的,用来描述整个软件的多个界面,并且能展示多个界面之间的跳转关系

二、xib的简单使用

1.建立xib文件

技术分享

建立的xib文件命名为appxib.xib

技术分享

2.对xib进行设置

  根据程序的需要,这里把view调整为自由布局

技术分享

建立view模型(设置长宽等参数)

技术分享

调整布局和内部的控件

技术分享

 

完成后的单个view

3.使用xib文件的代码示例

YYViewController.m文件代码如下:

 9 #import "YYViewController.h"
10 #import "YYapp.h"
11 
12 @interface YYViewController ()
13 @property(nonatomic,strong)NSArray *app;
14 @end
15 
16 @implementation YYViewController
17 
18 //1.加载数据信息
19 -(NSArray *)app
20 {
21     if (!_app) {
22         NSString *path=[[NSBundle mainBundle]pathForResource:@"app.plist" ofType:nil];
23         NSArray *temparray=[NSArray arrayWithContentsOfFile:path];
24         
25         //字典转模型
26         NSMutableArray *arrayM=[NSMutableArray array ];
27         for (NSDictionary *dict in temparray) {
28             [arrayM addObject:[YYapp appWithDict:dict]];
29         }
30         _app=arrayM;
31     }
32     return _app;
33 }
34 
35 //创建界面原型
36 - (void)viewDidLoad
37 {
38     [super viewDidLoad];
39     NSLog(@"%d",self.app.count);
40     
41     //九宫格布局
42     int totalloc=3;
43     CGFloat appviewW=80;
44     CGFloat appviewH=90;
45     CGFloat margin=(self.view.frame.size.width-totalloc*appviewW)/(totalloc+1);
46     
47     int count=self.app.count;
48     for (int i=0; i<count; i++) {
49         
50         int row=i/totalloc;
51         int loc=i%totalloc;
52         CGFloat appviewX=margin + (margin +appviewW)*loc;
53         CGFloat appviewY=margin + (margin +appviewH)*row;
54         YYapp *app=self.app[i];
55         
56         //拿出xib视图
57        NSArray  *apparray= [[NSBundle mainBundle]loadNibNamed:@"appxib" owner:nil options:nil];
58         UIView *appview=[apparray firstObject];
59         //加载视图
60         appview.frame=CGRectMake(appviewX, appviewY, appviewW, appviewH);
61         
62         UIImageView *appviewImg=(UIImageView *)[appview viewWithTag:1];
63         appviewImg.image=app.image;
64         
65         UILabel *appviewlab=(UILabel *)[appview viewWithTag:2];
66         appviewlab.text=app.name;
67         
68         UIButton *appviewbtn=(UIButton *)[appview viewWithTag:3];
69         [appviewbtn addTarget:self action:@selector(appviewbtnClick:) forControlEvents:UIControlEventTouchUpInside];
70         appviewbtn.tag=i;
71         
72         [self.view addSubview:appview];
73     }
74 }
75 
76 /**按钮的点击事件*/
77 -(void)appviewbtnClick:(UIButton *)btn
78 {
79     YYapp *apps=self.app[btn.tag];
80     UILabel *showlab=[[UILabel alloc]initWithFrame:CGRectMake(60, 450, 200, 20)];
81     [showlab setText:[NSString stringWithFormat: @"%@下载成功",apps.name]];
82     [showlab setBackgroundColor:[UIColor lightGrayColor]];
83     [self.view addSubview:showlab];
84     showlab.alpha=1.0;
85     
86     //简单的动画效果
87     [UIView animateWithDuration:2.0 animations:^{
88         showlab.alpha=0;
89     } completion:^(BOOL finished) {
90         [showlab removeFromSuperview];
91     }];
92 }
93 
94 @end

三、对xib进行连线示例

1.连线示例

新建一个xib对应的视图类,继承自Uiview

技术分享

 


在xib界面右上角与新建的视图类进行关联

技术分享

把xib和视图类进行连线

技术分享

2.连线后的代码示例

YYViewController.m文件代码如下:

 2 //  YYViewController.m
 3 //  10-xib文件的使用

 9 #import "YYViewController.h"
10 #import "YYapp.h"
11 #import "YYappview.h"
12 
13 @interface YYViewController ()
14 @property(nonatomic,strong)NSArray *app;
15 @end
16 
17 @implementation YYViewController
18 
19 //1.加载数据信息
20 -(NSArray *)app
21 {
22     if (!_app) {
23         NSString *path=[[NSBundle mainBundle]pathForResource:@"app.plist" ofType:nil];
24         NSArray *temparray=[NSArray arrayWithContentsOfFile:path];
25         
26         //字典转模型
27         NSMutableArray *arrayM=[NSMutableArray array ];
28         for (NSDictionary *dict in temparray) {
29             [arrayM addObject:[YYapp appWithDict:dict]];
30         }
31         _app=arrayM;
32     }
33     return _app;
34 }
35 
36 //创建界面原型
37 - (void)viewDidLoad
38 {
39     [super viewDidLoad];
40     NSLog(@"%d",self.app.count);
41     
42     //九宫格布局
43     int totalloc=3;
44     CGFloat appviewW=80;
45     CGFloat appviewH=90;
46     CGFloat margin=(self.view.frame.size.width-totalloc*appviewW)/(totalloc+1);
47     
48     int count=self.app.count;
49     for (int i=0; i<count; i++) {
50         
51         int row=i/totalloc;
52         int loc=i%totalloc;
53         CGFloat appviewX=margin + (margin +appviewW)*loc;
54         CGFloat appviewY=margin + (margin +appviewH)*row;
55         YYapp *app=self.app[i];
56         
57         //拿出xib视图
58        NSArray  *apparray= [[NSBundle mainBundle]loadNibNamed:@"appxib" owner:nil options:nil];
59         
60         //注意这里的类型名!
61         //UIView *appview=[apparray firstObject];
62         YYappview  *appview=[apparray firstObject];
63        
64         //加载视图
65         appview.frame=CGRectMake(appviewX, appviewY, appviewW, appviewH);
66           [self.view addSubview:appview];
67         
68         appview.appimg.image=app.image;
69         appview.applab.text=app.name;
70         appview.appbtn.tag=i;
71         
72         [ appview.appbtn addTarget:self action:@selector(appviewbtnClick:) forControlEvents:UIControlEventTouchUpInside];
73        
74     }
75 }
76 
77 /**按钮的点击事件*/
78 -(void)appviewbtnClick:(UIButton *)btn
79 {
80     YYapp *apps=self.app[btn.tag];
81     UILabel *showlab=[[UILabel alloc]initWithFrame:CGRectMake(60, 450, 200, 20)];
82     [showlab setText:[NSString stringWithFormat: @"%@下载成功",apps.name]];
83     [showlab setBackgroundColor:[UIColor lightGrayColor]];
84     [self.view addSubview:showlab];
85     showlab.alpha=1.0;
86     
87     //简单的动画效果
88     [UIView animateWithDuration:2.0 animations:^{
89         showlab.alpha=0;
90     } completion:^(BOOL finished) {
91         [showlab removeFromSuperview];
92     }];
93 }
94 
95 @end

YYappview.h文件代码(已经连线)

#import <UIKit/UIKit.h>

@interface YYappview : UIView
@property (weak, nonatomic) IBOutlet UIImageView *appimg;
@property (weak, nonatomic) IBOutlet UILabel *applab;
@property (weak, nonatomic) IBOutlet UIButton *appbtn;
@end
