5 个解决方案

#1

You have to use contentVerticalAlignment and contentHorizontalAlignment of the button.

您必须使用按钮的contentVerticalAlignment和contentHorizo​​ntalAlignment。

#2

Use ContentHorizontalAlignment as below

使用ContentHorizo​​ntalAlignment如下所示

btnObj.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;

#3

Swift Code

SWIFT代码

button.contentHorizontalAlignment = UIControlContentHorizontalAlignment.Left

#4

For those who are using Swift 3

对于那些使用Swift 3的人

button.contentHorizontalAlignment = .left

Above code align text to left border, so you might want little padding.

上面的代码将文本与左边框对齐，因此您可能需要少量填充。

button.contentEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0)

Setting to button titleLable alignment also works perfectly.

设置为按钮titleLable对齐也完美。

btn.titleLabel.textAlignment=NSTextAlignmentCenter;
