以前的表现如下:
在我生成拖动视图后:
这就是我从单元格生成拖动视图的方法:
private func setupDraggingViewForCell(cell: BWStudentWishlistBookCollectionViewCell) {
UIGraphicsBeginImageContextWithOptions(cell.bounds.size, false, 0)
cell.bookImageView.layer.renderInContext(UIGraphicsGetCurrentContext()!)
draggingView = UIImageView(image: UIGraphicsGetImageFromCurrentImageContext())
draggingView?.clipsToBounds = true
draggingView?.contentMode = .ScaleAspectFit
draggingView?.layer.masksToBounds = true
draggingView?.layer.cornerRadius = 10
view.addSubview(draggingView!)
UIGraphicsEndImageContext()
}
如您所见,只有一个角落是圆形的。为什么呢?

您可以将clipsToBounds设置为false,并且可能会解决您案例中的问题。否则它会显示封面的完整框架,然后你可以决定做什么。
draggingView?.clipsToBounds = false

您可以根据需要直接将此代码添加到自定义单元格中.......
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
imageView.layer.shadowColor = UIColor.blackColor().CGColor
imageView.layer.shadowOpacity = 1
imageView.layer.cornerRadius = 5
imageView.layer.shadowOffset = CGSizeZero
imageView.layer.shadowRadius = 2
//If you added Aspect to Fill
imageView.clipsToBounds = true
}
我希望这会对你有帮助......(Y)

不知道但是尝试围绕图像而不是imageView
func makeRoundedImage(image: UIImage, radius: Float) -> UIImage {
var imageLayer: CALayer = CALayer.layer
imageLayer.frame = CGRectMake(0, 0, image.size.width, image.size.height)
imageLayer.contents = (image.CGImage as! AnyObject)
imageLayer.masksToBounds = true
imageLayer.cornerRadius = 10
UIGraphicsBeginImageContext(image.size)
imageLayer.renderInContext(UIGraphicsGetCurrentContext())
var roundedImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return roundedImage
}
然后将图像设置为图像视图。并清除dragableView的背景颜色
希望它会有所帮助..!
