试试这个..

{
    UIButton * syncButton = (UIButton *) sender;
    [syncButton setBackgroundImage: <NormalImage.png>
                          forState: UIControlStateNormal];

}

Answer 4

您需要做的就是代替所有代码：

  UIImage *img = [UIImage imageNamed:@"yourImage.png"];
  [cell.theSyncButton setImage:img forState:UIControlStateSelected];

Answer 5

这是我的解决方案：我使用UIImageVIew作为按钮

例如，starIcon是一个UIImageView，我将其添加到我的自定义UITableViewCell按钮中。和ArticleCell是我的自定义UITableViewCell类。

在UITableView dataSource方法 cellForRowAtIndexPath ：

ArticleCell* cell = [tableView dequeueReusableCellWithIdentifier:@"reused"];
if (cell==nil) {
    NSLog(@"init tableViewCell");
    cell = [[ArticleCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"reused"];
    UITapGestureRecognizer* gesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(buttonCallback:)];
    gesture.numberOfTapsRequired=1;
    gesture.numberOfTouchesRequired=1;
    [cell.starIcon addGestureRecognizer:gesture];
    cell.starIcon.userInteractionEnabled=YES;
    NSLog(@"init tableViewCell end");        
}

确保设置 userInteractionEnabled == true;

然后，在buttonCallback方法中，您可以通过

获取UIimageView

    -(void)buttonCallback:(UIGestureRecognizer*)gestureRecognizer{
       UIImageView* star = (UIImageView*)[gestureRecognizer view];
    }

所以，你可以改变你的imageView。
