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:

@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];

// Do any additional setup after loading the view, typically from a nib.
