如何在觸摸時放大uitableview細胞圖像

Question

我正在使用以下代碼來檢測表格單元格圖像上的觸摸。 如何在觸摸時放大圖像？

我堅持的部分是如何使myFunction方法可以訪問cell.userSubmittedImageView？

來自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);  
}

假設您的userSubmittedImageView是UIImageView，您可以這樣做

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