我正在尝试以编程方式初始化UIButton
,但看到以下错误之一:
或者
for char in keys {
let btn: UIButton = UIButton.buttonWithType(UIButtonType.System) as UIButton
btn.frame = CGRectMake(0, 0, 20, 20)
btn.setTitle(char, forState: .Normal)
btn.sizeToFit()
btn.titleLabel?.font = UIFont.systemFontOfSize(20)
btn.backgroundColor = UIColor(hue: (216/360.0), saturation: 0.1, brightness: 0.81, alpha: 1)//
btn.setTitleColor(UIColor(white: 1.0, alpha: 1.0), forState: .Normal)
btn.setContentHuggingPriority(1000, forAxis: .Horizontal)
btn.setContentCompressionResistancePriority(1000, forAxis: .Horizontal)
btn.addTarget(self, action: Selector("handleBtnPress:"), forControlEvents: .TouchUpInside)
self.addSubview(btn)
}
最佳答案
UIButton
的便捷初始化程序已更改。
swift 3:
let btn = UIButton(type: .system) // note the lower case s
Swift 2.x:
let btn = UIButton(type: .System)
