回答by Noman Haroon
btnAddress.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.left
btnAddress.contentVerticalAlignment = UIControl.ContentVerticalAlignment.top
And now if you want the text to have some space from left add this
现在如果你想让文本从左边有一些空间添加这个
btnAddress.titleEdgeInsets = UIEdgeInsets(top: 0, left: 8, bottom: 0, right: 0)
btnAddress.titleEdgeInsets = UIEdgeInsets(top: 0, left: 8, bottom: 0, right: 0)
