UIButton上字体偏移

当设置UIButton对其方式使用

       // [button setTitleEdgeInsets:UIEdgeInsetsMake(0, 15, 0, 0)];

       // button.titleLabel.textAlignment = UITextAlignmentLeft;

不起作用时,可以用

        

        button.contentHorizontalAlignment =UIControlContentHorizontalAlignmentLeft;

        button.contentEdgeInsets =UIEdgeInsetsMake(0,18, 0, 0);
