UITableView没有正确绑定导致unrec…

错误1:[UIView tableView:numberOfRowsInSection:]: unrecognizedselector sent to instance 0x45fad0

错误2:setValue:forUndefinedKey:]: this class is not key valuecoding-compliant for the key tableView.'

 

What that is saying is that someone sent the‘tableView:numberOfRowsInSection:’ method to a UIView. And theUIView class does not recognize that method. My guess is that thedatasource for your tableView is connected to the view instead ofthe files owner.

查看xib的File's Owner点击弹出的框显示 ui之间的关系才比较清楚。

找到的原因是:self.viewController= [[CJQViewControlleralloc] initWithNibName:@"CJQ2ViewController"bundle:nil];

CJQ2ViewController.xib没有用CJQ2ViewController来初始化，并且CJQViewController里面没有实现tableView的相关方法。
