如何在Swift中更改按钮标题对齐？

Question

我想把一个Button上的标题设置为左边.但我尝试的一切都没有用.

附:

UILabelButton.titleLabel.textAlignment = .Left

要么:

UILabelButton.contentVerticalAlignment = UIControlContentVerticalAlignment // There is no left

按钮标题仍然居中.

还有其他房产吗？

Answer 1

用contentHorizontalAlignment.你必须使用UIControlContentHorizontalAlignment.Left.你需要使用horizontal没有vertical.

btn.contentHorizontalAlignment = UIControlContentHorizontalAlignment.Left

Swift 3.x

btn.contentHorizontalAlignment = .left

Answer 2

斯威夫特4

样例代码

对于我的要求，我想对准左 顶部

btnAddress.contentHorizontalAlignment = UIControlContentHorizontalAlignment.left
btnAddress.contentVerticalAlignment = UIControlContentVerticalAlignment.top

Swift 5更新：

btnAddress.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.left
btnAddress.contentVerticalAlignment = UIControl.ContentVerticalAlignment.top
