上一篇文章已经对ios页面进行了说明，接下来就是使用页面，给页面中添加子控件，在上面两篇创建的项目中，进行些许修改，成了现在的。先看效果：

代码：

修改ViewController

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor=[[UIColor alloc] initWithRed:0.3f green:0.35f blue:0.85f alpha:1.0f];
    
    UIView *view1=[[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)]//创建view ，view是矩形，0，0表示左上角坐标，后面的100，100代表宽高
    view1.backgroundColor=[[UIColor alloc] initWithRed:0.88f green:0.66f blue:0.11f alpha:0.8f];//给新创建的view设置背景颜色，便于观察
    [self.view addSubview:view1];//向ViewController中的view中添加子View
    
    //下面代码都是对上面的复制和修改，仅仅是坐标和颜色不同
    UIView *view2=[[UIView alloc] initWithFrame:CGRectMake(30, 30, 100, 100)];
    view2.backgroundColor=[[UIColor alloc] initWithRed:1.0f green:0.0f blue:0.6f alpha:0.8f];
    [self.view addSubview:view2];
    
    UIView *view3=[[UIView alloc] initWithFrame:CGRectMake(60, 60, 100, 100)];
    view3.backgroundColor=[[UIColor alloc] initWithRed:1.0f green:1.0f blue:0.6f alpha:0.8f];
    [self.view addSubview:view3];
    
    UIView *view4=[[UIView alloc] initWithFrame:CGRectMake(90, 90, 100, 100)];
    view4.backgroundColor=[[UIColor alloc] initWithRed:0.0f green:1.0f blue:0.0f alpha:0.8f];
    [self.view addSubview:view4];
    
    
    //self.view
    
    // Do any additional setup after loading the view, typically from a nib.
}

    [super didReceiveMemoryWarning];
