iOS UIButton左文字右图片,上图片下文字

一:默认是左图片右边文字

二:左文字右图片(直接拷贝代码到项目即可)

[btn setTitleEdgeInsets:UIEdgeInsetsMake(0, -btn.imageView.size.width, 0, btn.imageView.size.width)];
[btn setImageEdgeInsets:UIEdgeInsetsMake(0, btn.titleLabel.bounds.size.width, 0, -btn.titleLabel.bounds.size.width)];

三:上图片下文字(直接拷贝代码到项目即可)

    btn.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;//使图片和文字水平居中显示  
    [btn setTitleEdgeInsets:UIEdgeInsetsMake(btn.imageView.frame.size.height ,-btn.imageView.frame.size.width, 0.0,0.0)];//文字距离上边框的距离增加imageView的高度，距离左边框减少imageView的宽度，距离下边框和右边框距离不变  
    [btn setImageEdgeInsets:UIEdgeInsetsMake(0.0, 0.0,0.0, -btn.titleLabel.bounds.size.width)];//图片距离右边框距离减少图片的宽度，其它不边
