IOS 纯代码添加 Button Image Label 添加到自定义View中

@interface ViewController ()
/**获取.plist数据*/
@property (nonatomic,strong) NSArray *apps;
@end

@implementation ViewController

- (void)viewDidLoad {
[super viewDidLoad];

//九宫格的总列数
int totalColumns=5;

//1.1个格子的尺寸
CGFloat appW=50;
CGFloat appH=60;

//2.计算间隙 ＝（控制器view的宽度 -5*应用宽度）/应用宽度+1
CGFloat margin=(self.view.frame.size.width-totalColumns*appW)/(totalColumns+1);

//3.要的应用个数创建对应的格子

for (int index=0; index<self.apps.count; index++)
{
//3.1 创建1个格子
UIView *appView=[[UIView alloc]init];

//设置背景色
appView.backgroundColor=[UIColor whiteColor];

//3.2计算行号和列号
int row =index /totalColumns;
int col =index % totalColumns;

CGFloat appX =margin+ col*(appW + margin);
CGFloat appY =margin+ row*(appH + margin);

appView.frame=CGRectMake(appX, appY, appW, appH);

//3.3添加格子到控制器的View
[self.view addSubview:appView];

//3.4添加 内部的小控件
//取出index位置对应的应用信息
NSDictionary *appInfo=self.apps[index];

//3.4.1添加图片
UIImageView *iconView=[[UIImageView alloc]init];
CGFloat iconW=35;
CGFloat iconH=35;
CGFloat iconX=(appW-iconW)*0.5;
CGFloat iconY=0;
iconView.frame=CGRectMake(iconX, iconY, iconW, iconH);
//iconView.backgroundColor=[UIColor grayColor];
iconView.image=[UIImage imageNamed:appInfo[@"icon"]];
[appView addSubview:iconView];

//3.4.2 添加名字
UILabel *nameLabel=[[UILabel alloc]init];
CGFloat namgeX=0;
CGFloat nameY=iconY+iconH;
CGFloat nameW=appW;
CGFloat nameH=20;
nameLabel.frame=CGRectMake(namgeX, nameY, nameW, nameH);
nameLabel.backgroundColor=[UIColor greenColor];
nameLabel.text=appInfo[@"name"];
nameLabel.font=[UIFont systemFontOfSize:8];//设置字体大小
nameLabel.textAlignment=NSTextAlignmentCenter;//字体居中
[appView addSubview:nameLabel];

//3.4.3添加下载按钮

UIButton *downloadBtn=[[UIButton alloc]init];
CGFloat downloadX=5;
CGFloat downloadY=nameY+nameH;
CGFloat downloadW=appW-2*downloadX;
CGFloat downloadH=20;

downloadBtn.frame=CGRectMake(downloadX, downloadY, downloadW, downloadH);
// downloadBtn.backgroundColor=[UIColor brownColor];

//设置按钮图片，普通状态
//  downloadBtn.imageView.image=[UIImage imageNamed:@"buttongren"];
UIImage *normalImage=[UIImage imageNamed:@"buttongreen"];
[downloadBtn setBackgroundImage:normalImage forState:UIControlStateNormal];

//设置按钮图片，高亮状态
UIImage *highighedlImage=[UIImage imageNamed:@"buttongreen_highlighted"];
[downloadBtn setBackgroundImage:highighedlImage forState:UIControlStateHighlighted];

//设置按钮文字
//downloadBtn.titleLabel.text=@"下载";
[downloadBtn setTitle:@"下载" forState:UIControlStateNormal];
[downloadBtn setTitle:@"更新" forState:UIControlStateHighlighted];

//设置按钮文字的大小
downloadBtn.titleLabel.font=[UIFont systemFontOfSize:8];

[appView addSubview:downloadBtn];
}
