Ios 搜索文本字段结果不可选

我正在使用UITextFields作为搜索栏。我必须这样做，因为我有多个输入供人们搜索。搜索工作进行得很顺利。事实上，文本字段在内存方面比普通搜索栏工作得更好。唯一的问题是我无法选择结果单元格。当我按下电池时，什么也没发生。我甚至在didselect中放了一个log语句，而该单元格甚至没有得到该操作。请帮忙

此代码是在UIViewController中还是在UITableViewController中？可能是您的点击手势识别器干扰了表视图的识别器。在dismissKeyboard方法中输入一个日志，查看在您尝试选择单元格时是否调用了该方法。是，每次我按下单元格时都会调用Dismise keyboard。我怎样才能避免这种情况？如果我注释掉点击识别器，它会工作…有没有一种方法可以实现点击呢？我知道了…我刚刚注释掉了我的Discover键盘方法，让return键处理它…再次感谢rdelmar！
