iphone - 如何检测用户是否直接单击 cell.imageView 而不是 tableview 单元格中的标签？

Question

在我的 tableView 单元格中我有:

cell.imageView.image = image;

如何检测用户是否直接点击了该图像，而不是 cell.textLabel？

Answer 1

将 UITapGestureRecognizer 添加到 imageView。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    /* ... */
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        cell.imageView.image = /*...*/

        UITapGestureRecognizer *tapGesture = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageTapped:)] autorelease];
        [cell.imageView addGestureRecognizer:tapGesture];
        cell.imageView.userInteractionEnabled = YES;
    }
    /* ... */
}

- (void)imageTapped:(UITapGestureRecognizer *)gesture {
    UITableViewCell *cell = [[[gesture view] superview] superview];
    NSIndexPath *tappedIndexPath = [self.tableView indexPathForCell:cell];
    NSLog(@"Image Tap %@", tappedIndexPath);
}
