ios – 确定CATextLayer中textBox的大小

概述我写了这段代码,效果很好;但我需要弄清楚CATextLayer中文本的大小才能完成它？我使用轻敲手势来获取x / y的想法,输入文本并让它弄清楚在CATextLayer对象/视图中绘制它所需的CGSize. overload func ViewDidLoad() let tap = UITapGestureRecognizer(target: self, action: #selector 我写了这段代码,效果很好;但我需要弄清楚CATextLayer中文本的大小才能完成它？我使用轻敲手势来获取x / y的想法,输入文本并让它弄清楚在CATextLayer对象/视图中绘制它所需的CGSize.

overload func VIEwDIDLoad()    let tap = UITapGestureRecognizer(target: self,action: #selector(handleTap))    container.addGestureRecognizer(tap)} func handleTap(gesture: UITapGestureRecognizer) {    let location = gesture.location(in: gesture.vIEw)    startX = location.x    startY = location.y    drawText(onLayer: vIEw.layer,fromPoint: CGPoint(x: startX,y: startY),topoint: CGPoint(x:location.x,y:location.y))}func drawText(onLayer layer: CALayer,fromPoint start: CGPoint,topoint end:CGPoint) {    let myTextLayer = CATextLayer()    myTextLayer.string = "Google"    myTextLayer.backgroundcolor = UIcolor.black.cgcolor    myTextLayer.foregroundcolor = UIcolor.white.cgcolor    //myTextLayer.frame = vIEw.bounds    let myBounds = CGRect(origin: start,size: CGSize(wIDth: 128,height: 32))    myTextLayer.frame = myBounds    layer.addSublayer(myTextLayer)}

解决方法 是的,雅虎！

这就是答案！

myTextLayer.preferredFrameSize()
