如果您的表视图处于编辑模式(例如。[tableView setEditing:YES animated:NO];)，你需要设置tableView。allowsSelectionDuringEditing = YES;

如果你看了这个，那么问题还是没有解决。

我有自定义单元格，其中复选框“用户交互启用”是禁用的。所以，我只要打开它。祝你好运。

即使另一个答案已经被接受，我将为观察这个问题的人补充一个可能的问题和解决方案:

If you have automatic reference counting (ARC) turned on, you may find that even after assigning your controller as a delegate of the view, the view's messages to the controller are not being received because ARC is deleting the controller. Apparently the UITableView's delegate pointer does not count as a reference for the ARC, so if that is the only reference to it, the controller will be dealloc'd. You can verify whether or not this is happening by implementing the dealloc method on the controller and setting a breakpoint or NSLog call there.

解决方案是在其他地方使用强引用跟踪控制器，直到确定不再需要它为止。

添加@interface ExampleViewController () <UITableViewDelegate, UITableViewDataSource> 在故事板中进行委托

添加代码 - （void）tableView：（UITableView *）tableView didSelectRowAtIndexPath：（NSIndexPath *）indexPath { UITableViewCell *cell = [tableView cellForRowAtIndexPath：indexPath]; NSString *cellText = cell.textLabel.text; }

如果UITapGestureRecognizer出现问题，你可以修复这个:

在故事板:

在Objective-C代码中:

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)]; 
[self.view addGestureRecognizer:tap];

[tap setCancelsTouchesInView:NO];

Swift代码:

let tap = UITapGestureRecognizer(target: self, action:Selector("dismissKeyboard"))
view.addGestureRecognizer(tap)

tap.cancelsTouchesInView = false

我刚遇到这个问题，但它并没有马上发生;在选择了几个单元格之后，它们将停止调用didSelectItemAtIndexPath。我意识到问题是集合视图将allowmultipleselection设置为TRUE。因为单元格从未被取消选择，这阻止了未来调用didSelectItemAtIndexPath。
