我想在Swift 3中创建这种类型的视图。我们如何创建我无法做到这一点请帮助任何帮助,将不胜感激。在此先感谢Swift中的三角形Imageview

是否要将图像裁剪为三角形?我为这种情况做了一个例子
func createTriangleImage() {
// your UIImage
let ballImage = UIImage(named: "ball")!
// your imageView which you wanted to be triangle.
// I made the example via layers as it seems easier to me
// so you dont need UIImageView here, UIView is enough
let viewWithImage = UIView(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
// Layer for your image
let imageLayer = CALayer()
// Setting the image
imageLayer.contents = ballImage.cgImage
imageLayer.frame = viewWithImage.frame
viewWithImage.layer.addSublayer(imageLayer)
//view - is your main view where you wanted to put the triangle image
view.addSubview(viewWithImage)
// Creating a triangle path to draw triangle mask later
let path = UIBezierPath()
path.move(to: CGPoint(x: 20, y: 0))
path.addLine(to: CGPoint(x: 40, y: 40))
path.addLine(to: CGPoint(x: 0, y: 40))
path.close()
// Creating a mask layer
let maskLayer = CAShapeLayer()
maskLayer.path = path.cgPath
maskLayer.fillColor = UIColor.red.cgColor
// Setting the mask
imageLayer.mask = maskLayer
}
**我想在Swift 3 **中创建这种类型的视图**它意味着什么? – seggy
这听起来像你想用三角形路径掩盖图像视图? –
对透明度有影响的三角形图像有帮助吗? – werediver
