问题描述
我在左对齐 UIButton 的文本时遇到问题.我也尝试将其更改为 .Right 但它仍然保持居中.我也试过 aButton.imageEdgeInsets = UIEdgeInsets(top: 0, left: 20, bottom: 0, right: 0) 而不是 aButton.titleLabel?.textAlignment = .Left但这也不会改变任何事情.是否有另一种方法可以以编程方式更改 UIButton 标题的对齐方式?
I'm having a problem left-aligning a UIButton's text. I also tried changing it to .Right but it still stays centered. I also tried aButton.imageEdgeInsets = UIEdgeInsets(top: 0, left: 20, bottom: 0, right: 0) instead of aButton.titleLabel?.textAlignment = .Left but that doesn't change anything either. Is there an alternative way to programmatically change the alignment of a UIButton title's?
allButtonViews = UIView(frame: CGRectMake(0, 44, 100, 100))
allButtonViews.backgroundColor = .redColor()
let campusButton = UIButton(type: UIButtonType.System) as UIButton
aButton.frame = CGRectMake(0, 0, 300, 70)
aButton.setTitle("A", forState: .Normal)
aButton.titleLabel?.textColor = .blueColor()
aButton.titleLabel?.textAlignment = .Left
aButton.backgroundColor = .whiteColor()
sortView.addSubview(aButton)
view.addSubview(allButtonViews)
推荐答案
试试这个:
button.contentHorizontalAlignment = .left
