1. 新建appViewModel
1.1声明需要的属性
//NSString一般用copy来修饰
@property(nonatomic,copy)NSString *name;
@property(nonatomic,copy)NSString *icon;
//字典转模型的方法
- (id)initWithDict:(NSDictionary *)dict;
1.2字典转模型
- (id)initWithDict:(NSDictionary *)dict{
if(self = [super init]){
self.name = dict[@"name"];
self.icon = dict[@"icon"];
}
return self;
}
2.ViewController
#import "ViewController.h"
#import "appViewModel.h"
@interface ViewController ()
@property(nonatomic,strong)NSArray *apps;
@end
@implementation ViewController
- (NSArray *)apps{
if(_apps == nil){
//1-获取plist文件的路径
NSString *path = [[NSBundle mainBundle]pathForResource:@"app.plist" ofType:nil];
//2-读取文件
NSArray *dictArray = [NSArray arrayWithContentsOfFile:path];
//3-字典转模型
NSMutableArray *tempArr = [NSMutableArray array];
for(NSDictionary *dic in dictArray){
appViewModel *appModel = [[appViewModel alloc]initWithDict:dic];
[tempArr addObject:appModel];
}
_apps = tempArr;
}
return _apps;
}
- (void)viewDidLoad{
[super viewDidLoad];
//1-设置frame的相关属性
CGFloat appViewW = 100;
CGFloat appViewH = 120;
CGFloat spaceX = 20;
CGFloat spaceY = 30;
CGFloat topMargin = 30;
CGFloat leftmargin = (self.view.frame.size.width - 3 * appViewW - 2 * spaceX) * 0.5;
//2-创建格子
for( int i = 0; i < self.apps.count; i ++){
//2.1-创建一个格子视图
UIView *appView = [[UIView alloc]init];
int row = i / 3;//行号
int col = i % 3;//列号
CGFloat appViewX = leftmargin + (appViewW + spaceX) * col;
CGFloat appViewY = topMargin + (appViewH + spaceY) * row;
//2.2设置frame
appView.frame = CGRectMake(appViewX, appViewY, appViewW, appViewH);
//2.3添加
[self.view addSubview:appView];
appViewModel *appViewModel = self.apps[i];
//2.4添加图片
UIImageView *head = [[UIImageView alloc]init];
CGFloat headW = 60;
CGFloat headX = (appViewW - headW) *0.5;
CGFloat headY = 0;
CGFloat headH = 60;
head.image = [UIImage imageNamed: appViewModel.icon ];
head.frame = CGRectMake(headX, headY, headW, headH);
[appView addSubview:head];
// head.backgroundColor = [UIColor blueColor];
// 2.5添加label
// 2.5.1 创建一个文本标签
UILabel *nameLabel = [[UILabel alloc]init];
CGFloat nameLabelX = 0;
CGFloat nameLabelY = headY + headH;
CGFloat nameLabelW = appViewW;
CGFloat nameLabelH = 30;
nameLabel.frame = CGRectMake(nameLabelX, nameLabelY, nameLabelW, nameLabelH);
[appView addSubview:nameLabel];
// nameLabel.backgroundColor = [UIColor grayColor];
nameLabel.text = appViewModel.name;
// 2.5.2设置文字大小
nameLabel.font = [UIFont systemFontOfSize:13];
// 2.5.3设置文字居中
nameLabel.textAlignment = NSTextAlignmentCenter;
// 2.6添加button
UIButton *downLoadBtn = [[UIButton alloc]init];
CGFloat downLoadBtnX = 10;
CGFloat downLoadBtnY = nameLabelY + nameLabelH + 10;
CGFloat downLoadBtnW = appViewW - downLoadBtnX *2;
CGFloat downLoadBtnH = 30;
downLoadBtn.frame = CGRectMake(downLoadBtnX, downLoadBtnY, downLoadBtnW, downLoadBtnH);
[appView addSubview:downLoadBtn];
// downLoadBtn.backgroundColor = [UIColor greenColor];//设置背景色
[downLoadBtn setTitle:@"下载" forState:UIControlStateNormal];//设置文字
[downLoadBtn setBackgroundImage:[UIImage imageNamed:@"buttongreen"] forState:UIControlStateNormal];
[downLoadBtn setBackgroundImage: [UIImage imageNamed:@"buttongreen_highlighted"] forState:UIControlStateHighlighted];
// downLoadBtn.
// 按钮内部至少有两个控件,一个label,一个imageView,
downLoadBtn.titleLabel.font = [UIFont systemFontOfSize:14];
}
}
