在我的情况下，我犯了一个小错误，我分配:

tableView.isUserInteractionEnabled = false

它应该是:

tableView.isUserInteractionEnabled = true

我重复了之前所有的答案，但没有一个对我有帮助。经过反复试验，我找到了一个不同的解决方案。我有一个UIImageView覆盖整个单元格(作为背景)。默认情况下，UIImageView禁用用户交互。通过启用imageviews用户交互委托方法-didSelectRowAtIndexPath:再次被调用。 如。

cell.imgView.userInteractionEnabled = YES;

另一种可能性是UITapGestureRecognizer可以吃掉事件，就像这里的情况:https://stackoverflow.com/a/9248827/214070

我没有怀疑这个原因，因为表格单元格仍然会突出显示蓝色，就像水龙头通过一样。

我的问题不在上面。太差劲了。但我想我应该把它列在这里，也许它能帮助到别人。

I have a tableViewController that is my "base" controller and then I create subclasses of this controller. I was writing all my code in the tableView:didSelectRowAtIndexPath routine in the "base" class. Completely forgetting that by default this routine had also been created (albeit with no code that did anything) in all of my subclasses as well. So when I ran my app, it ran the subclass version of the code, did nothing, and made me sad. So of course, once I removed the routine from the subclasses, it used mt "base" class routine and I'm in business.

我知道。别笑。但也许这能帮别人省下我浪费的一小时…

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

对于Xcode 6.4, Swift 1.2。在IB中选择“标签”被改变了。我不知道是怎么改变的，为什么改变。将其设置为“单一选择”使我的表格视图单元格再次可选。
