我在我的UIImageView的绘制方法中设置了一些属性。但是，这些似乎没有任何影响。我看不到任何圆角，并且没有掩蔽效果。该视图如下：为绘制UIImageView设置圆角半径
//
// RoundImage.swift
//
//
import UIKit
class RoundImage: UIImageView {
//------------------
//MARK: - Setup and Initialization
//------------------
override init(frame: CGRect) {
super.init(frame: frame)
self.initialize()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.initialize()
}
override func draw(_ rect: CGRect) {
super.draw(rect)
self.layer.cornerRadius = 30
self.layer.masksToBounds = true
self.clipsToBounds = true
}
//Setups content, styles, and defaults for the view
private func initialize(){
self.initStyle()
}
//Sets static content for the view
private func staticContent() {
}
//Styles the view's colors, borders, etc at initialization
private func initStyle(){
}
//Styles the view for variables that must be set at runtime
private func runtimeStyle(){
//TODO: These values cannot be changed in interface builder, but they should be able to be
}
//------------------
//MARK: - Interface Builder Methods
//------------------
//Sets the view up for interface builder with runtime styling and temp display values
override func prepareForInterfaceBuilder() {
self.runtimeStyle()
self.staticContent()
}
//------------------
//MARK: - Lifecycle Methods
//------------------
//Sets the view up with runtime styling and values
override func awakeFromNib() {
super.awakeFromNib()
self.runtimeStyle()
self.staticContent()
}
}
可能是愚蠢的事情要问，但如果你使用这个在故事板一个UIImageView，你一定要设置类？如果你已经这样做了，在'draw'函数中添加一个断点并检查它是否在那里断开。 –
@PratikPatel是的，我设置了类。奇怪的是，它并没有在我的绘画方法中达到我的断点。 – steventnorris
