UIView圆角 - 斯威夫特2.0? [英] UIView rounded Corner - Swift 2.0?
问题描述
我试图将一些项目更新为Swift 2.0。我有一个视图,左上角有一个圆角。一切都在Swift< 1.2,但现在,再也没有圆角了。
Ill try to update some projects to Swift 2.0. I´ve got a View, with a rounded corner top left. Everything works fine in Swift < 1.2, but now, there is no rounded corner anymore.
没有警告,没有错误,没有圆角。
No Warnings, no Errors, just no rounded corner.
这是它在Swift< 1.2。
This is how it works in Swift < 1.2.
let maskPath = UIBezierPath(roundedRect: contentView.bounds,byRoundingCorners: .TopLeft, cornerRadii: CGSize(width: 10.0, height: 10.0))
let maskLayer = CAShapeLayer(layer: maskPath)
maskLayer.frame = contentView.bounds
maskLayer.path = maskPath.CGPath
contentView.layer.mask = maskLayer
任何人都知道这里有什么问题吗?我没有在文档中找到任何更改。
Anyone know whats wrong here? Ill dont find any changes in the documentation.
