Instead of all that code you have all you have to do is:

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

Answer 5

Here is my solution: i use UIImageVIew as button

for example , the starIcon is an UIImageView ,which i add into my custom UITableViewCell as button. and ArticleCell is my custom UITableViewCell class.

in UITableView dataSource method 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");        
}

make sure you set userInteractionEnabled == true;

then , in your buttonCallback method ,you can get UIimageView by

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

so , you can change your imageView.
