对齐UIView和CAShapeLayer的问题

我在对齐UIView和CAShapeLayer时遇到问题。对齐UIView和CAShapeLayer的问题

下面是示例代码演示该问题：

import UIKit 

class ViewController: UIViewController { 
    override func viewDidLoad() { 
     super.viewDidLoad() 

     let square = UIView(frame: CGRect(x: 100, y: 100, width: 100, height: 100)) 
     square.transform = CGAffineTransformMakeRotation(CGFloat(20*M_PI/180)) 
     square.backgroundColor = UIColor.grayColor() 
     view.addSubview(square) 

     let strokeLayer = CAShapeLayer() 
     strokeLayer.path = UIBezierPath(rect: square.bounds).CGPath 
     strokeLayer.position = square.center 
     strokeLayer.setAffineTransform(square.transform) 

     strokeLayer.fillColor = UIColor.clearColor().CGColor 
     strokeLayer.strokeColor = UIColor.redColor().CGColor 
     strokeLayer.lineWidth = 1 

     view.addSubview(square) 
     view.layer.addSublayer(strokeLayer) 
    } 
}

下面是结果的图像：

如何获得两个对齐？

你需要做的只是改变你的形状层是什么补充：

strokeLayer.frame = square.layer.bounds

右后：

let strokeLayer = CAShapeLayer()

即，

let strokeLayer = CAShapeLayer() 
strokeLayer.frame = square.layer.bounds 
strokeLayer.path = UIBezierPath(rect: square.bounds).CGPath 
strokeLayer.position = square.center 
strokeLayer.setAffineTransform(square.transform) 

strokeLayer.fillColor = UIColor.clearColor().CGColor 
strokeLayer.strokeColor = UIColor.redColor().CGColor 
strokeLayer.lineWidth = 1

如果位置（0,0）

strokeLayer.position = CGPointMake(0, 0)

没有。看起来像这样：http://imgur.com/YvHmZr8 – Trappar

也从您的形状图层中删除变换 – nielsbot
