我有一个名为image
的UIImage
,我想改变它在imageView
内部的位置,以便可以将其向下拖动大约30px。有人能告诉我如何做吗?这是我的代码,但效果不正确。
var image = UIImage()
var imageView = UIImageView(frame: CGRectMake(0, 0, view.frame.size.height * 0.22, view.frame.size.height * 0.22))
imageView.center = CGPointMake(self.view.center.x, view.frame.size.height * 0.414)
imageView.image = self.image
imageView.layer.cornerRadius = imageView.frame.size.width / 2
imageView.layer.borderWidth = 2.0
imageView.layer.borderColor = UIColor(red: 254.0/255, green: 216.0/255, blue: 0/255, alpha: 1.0).CGColor
imageView.clipsToBounds = true
imageView.layer.contentsRect = CGRectMake(0, 20, imageView.frame.size.width, imageView.frame.size.height) //This is where I have being trying to do it but no success.
imageView.contentMode = .ScaleAspectFill
view.addSubview(imageView)
