iphone - 如何在触摸时放大 uitableview 单元格图像

Question

我正在使用以下代码来检测表格单元格图像上的触摸。我将如何着手放大那个触摸的图像？

我坚持的部分是如何使 cell.userSubmittedImageView 可从 myFunction 方法访问？

来自 cellForRowAtIndexPath: 方法

...
    cell.userSubmittedImageView.userInteractionEnabled = YES;
    cell.userSubmittedImageView.tag = indexPath.row;

    UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(myFunction:)];
    tapped.numberOfTapsRequired = 1;
    [cell.userSubmittedImageView addGestureRecognizer:tapped];

    return cell;  
}
-(void)myFunction :(id) sender
{
    UITapGestureRecognizer *gesture = (UITapGestureRecognizer *) sender;
    NSLog(@"Tag = %d", gesture.view.tag);  
}

假设你的 userSubmittedImageView 是一个 UIImageView 你可以做

UIImageView * userSubmittedImageView = (UIImageView *)gesture.view;
