self.layerView.W = 200;
self.layerView.H = 200;
self.layerView.center = SCREEN_CENTER;
[self.view addSubview:self.layerView];
//給視圖添加一個藍色子視圖
CALayer *blueLayer = [CALayer layer];
blueLayer.backgroundColor = [UIColor blueColor].CGColor;
blueLayer.frame = CGRectMake(50, 50, 100, 100);
[self.layerView.layer addSublayer:blueLayer];
