didSelectRowAtIndexPath：未被调用 [英] didSelectRowAtIndexPath: not being called

问题描述

我有 UITableView 作为我的 UIScrollVIew 的子视图，这是我的<$控制的主视图C $ C> MainViewController 。

I have a UITableView as a subview of my UIScrollVIew, which is the main view controlled by my MainViewController.

在MainViewController.h中

In MainViewController.h

@interface MainViewController : UIViewController <UIGestureRecognizerDelegate, UITableViewDelegate, UITableViewDataSource>

// other stuff here...

@property (weak, nonatomic) IBOutlet UITableView *myTableView;

在MainViewController.m中

In MainViewController.m

@synthesize myTableView;

// other stuff here...

- (void)viewDidLoad {
    myTableView.delegate = self;
    myTableView.datasource = self;
}

// other stuff here...

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath {
   [self performSegueWithIdentifier:@"listAttributesSegue" sender:self];
}

我知道 didSelectRowAtIndexPath 没有被调用，因为我已经在方法本身和它内部的代码行上设置了断点，并且都没有被调用。我也知道数据源工作正常，因为我有其他功能可以在运行时修改单元格，并且它们工作正常。我使用最新的Xcode和iOS 5.0设置作为开发目标。我搜索并搜索了一个答案。任何人都有任何想法？

I know that didSelectRowAtIndexPath is not being called because I have set breakpoints on both the method itself and the line of code inside it, and neither is being called. I also know that the datasource is working correctly because I have other functions which modify the cells at runtime and they are working perfectly fine. I am using the latest Xcode with iOS 5.0 set as the development target. I have searched and searched for an answer. Anyone have any ideas?

编辑：
我找到了答案。我为myTableView的superView设置了 UITapGestureRecognizer 。这超出了选择呼叫。相信任何人都认为可能是这样。在我将其标记为正确之前，您的答案已被删除。

I have found the answer. I had a UITapGestureRecognizer set for myTableView's superView. This overrode the selection call. Credit to whoever suggested that that might be it. Your answer was deleted before I could mark it correct.

编辑2：
很多人一直在评论此事，所以我虽然会分享它。如果您遇到此问题，只需将 myGestureRecognizer.cancelsTouchInView 设置为 false ，一切正常。

Edit 2: A lot of people have been commenting about this, so I though I would share it. If you are experiencing this problem, simply set myGestureRecognizer.cancelsTouchInView to false and everything should work fine.

将 cancelsTouchesInView 属性设置为手势识别器上没有，允许表视图拦截事件。

Set the cancelsTouchesInView property to NO on the gesture recogniser to allow the table view to intercept the event.
