检查- hightforrowatindexpath是否不返回0。

在我的情况下，didSelctRowAtIndexPath不调用是因为我在tableView的Selection属性中没有选择，设置为单一选择解决了我的问题

检查- hightforrowatindexpath是否不返回0。

我在我的表视图上放了一个UITapGestureRecognizer来消除键盘，这阻止了didSelectRowAtIndexPath:被调用。希望它能帮助到别人。

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…

记住在viewDidLoad方法中设置数据源和委托，如下所示:

[self.tableView setDelegate:self];

[self.tableView setDataSource:self];
