下午好,
我正在尝试通过在TableViewController(TableView)中单击配置文件图像来创建一个ProfileViewController(加载用户配置文件,如配置文件图像,图片和图片)。
目前无法正常工作,因为我触摸的所有东西都会进入Segue(帖子的segue,你可以看到条目,喜欢和评论)但我需要创建一些东西(也许是触摸手势)该作者的作者形象,并告诉我他的个人资料。
我尝试过创建一个Tap Gesture Recognizer,但它没有用。也是一个直接在故事板中的Segue行动,它不起作用。
我将向您展示一个例子,因为最终它就像Facebook墙一样:
如果我触摸个人资料图片,则会显示包含其信息的用户个人资料页面。我希望实现这一点,但使用TableView中的图像。
这就是我现在所得到的:

我曾经用手势识别器做到这一点......
UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapOnCheck:)];
tapped.numberOfTapsRequired = 1;
tapped.numberOfTouchesRequired = 1;
tapped.cancelsTouchesInView = YES;
[cell.imageView addGestureRecognizer:tapped];
正如您所看到的,我的目标行动是&#34; tapOnCheck:&#34;我的图像是cell.imageView,但您可以简单地将此代码调整为您的代码...
希望这有帮助!
再见

您可以尝试简单的解决方案。
从细胞中移除所有segues。 然后你需要覆盖CarTableViewCell,UIView的方法,该方法调用: - (void)touchesBegan:(NSSet *)触及withEvent:(UIEvent *)事件; 在此方法中检测触摸位置。将其与图像的位置进行比较。 如果触摸位置在图像中 - 向单元格的委托(它是您的控制器)发送消息,表示触摸单元格中的图像。 否则 - 向小区的代表发送消息,该消息表示在Cell中的其他位置触摸。
然后选择segue推。
希望这会对你有所帮助。
