我尝试在CALayer中添加自定义视图。

我想把一些按钮和标签放在里面,但我担心我无法做到。我像这样制作CALabel:
func addRectangleToLayer(x: CGFloat, y: CGFloat, width: CGFloat, height: CGFloat, layer: CALayer, index: UInt32 ) {
var sublayer = CALayer()
sublayer.backgroundColor = UIColor.whiteColor().CGColor
sublayer.shadowOffset = CGSizeMake(0, 3);
sublayer.shadowRadius = 5.0;
sublayer.shadowColor = UIColor.blackColor().CGColor
sublayer.shadowOpacity = 0.8;
sublayer.cornerRadius = 12.0;
sublayer.frame = CGRectMake(x, y, width, height);
sublayer.borderColor = UIColor.blackColor().CGColor;
sublayer.borderWidth = 0.5;
//An example
let label = UILabel()
label.text = "LOREN"
sublayer.contents = label
layer.insertSublayer(sublayer, atIndex: index)
}
有可能做我想做的事吗?
非常感谢,请原谅我的英语水平

如果您创建UIView
,则可以为此目的访问其layer
媒体资源:
let label = UILabel()
label.text = "LOREN"
var sublayer = label.layer;
// .. the rest of your layer initialization
sublayer.backgroundColor = UIColor.whiteColor().CGColor
sublayer.shadowOffset = CGSizeMake(0, 3);
sublayer.shadowRadius = 5.0;
sublayer.shadowColor = UIColor.blackColor().CGColor
sublayer.shadowOpacity = 0.8;
sublayer.cornerRadius = 12.0;
sublayer.frame = CGRectMake(x, y, width, height);
sublayer.borderColor = UIColor.blackColor().CGColor;
sublayer.borderWidth = 0.5;
// .. ended original source initialization
layer.insertSublayer(sublayer, atIndex: index)
