調整原生UIButton中title和image位置僅需調用此方法:

/**
 *  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);
    //圖片右移
    button.imageEdgeInsets = UIEdgeInsetsMake(0.0, titleSize.width, 0.0, -titleSize.width);
}

在設置UIbutton title和image的情況下,系統會自動計算文本框和圖片的Frame,從而調整兩者位置.
