iOS-调整UIButton的title和image的位置

调整原生UIButton中title和image位置仅需调用此方法:

/**
 *  重新布局UIbutton
 *
 *  @param button 所布局的UIbutton
 */
-(void)layoutBtnWithBtn:(UIButton *)button{
    button.titleLabel.backgroundColor = button.backgroundColor;
    button.imageView.backgroundColor = button.backgroundColor;

    CGSize titleSize = button.titleLabel.bounds.size;
    CGSize imageSize = button.imageView.bounds.size;
    NSLog(@"titleSize :%@ \n imageSize:%@",NSStringFromCGSize(titleSize),NSStringFromCGSize(imageSize));
    //文字左移
    button.titleEdgeInsets = UIEdgeInsetsMake(0.0, -imageSize.width, 0.0, imageSize.width);
    //图片右移
    button.imageEdgeInsets = UIEdgeInsetsMake(0.0, titleSize.width, 0.0, -titleSize.width);
}

在设置UIbutton title和image的情况下,系统会自动计算文本框和图片的Frame,从而调整两者位置.
