使用 CGAffineTransformMakeRotation 时 UIImageview 旋转不起作用 [英] UIImageview rotation is not working when using CGAffineTransformMakeRotation

问题描述

我正在使用 CGAffineTransformMakeRotation 旋转 UIImageView.旋转工作正常.当我尝试将该图像获取到另一个 UIImageView 时，旋转不起作用.

I am rotating UIImageView with CGAffineTransformMakeRotation. Rotation is working fine. When I tried to get that image to another UIImageView , rotation is not working.

编码 1:

@IBAction func rotateAcn(sender: UIButton) {

rotatingImageVw.transform = CGAffineTransformMakeRotation(0.22)

}

输出 1

编码 2:

@IBAction func getRotatedImage(sender: UIButton) {

newImageView.image = rotatingImageVw.image

}

输出 2

我不知道为什么会这样?我需要 Output 2 和 Output 1 一样.请指导我如何解决这个问题?

I dont know why this happening? I need Output 2 as in Output 1 . Kindly guide me how to solve this?

推荐答案

Swift 5 的解决方案:

Solution for Swift 5:

rotatingImageVw.transform = rotatingImageVw.transform.rotated(by: CGFloat(Double.pi / 4))
