Answer 1

As per Apple documentation registerForRemoteNotificationTypes：在iOS 8中已弃用，您可以使用registerForRemoteNotifications和registerUserNotificationSettings。

Answer 2

罪魁祸首可以在顶部的第三行看到

2014-09-17 08:58:00.067 [783:12416] -[NSArrayI numberOfSectionsInTableView:]: unrecognized selector sent to instance 0x7f9250fa9e00
2014-09-17 08:58:00.085 [783:12416] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI numberOfSectionsInTableView:]: unrecognized selector sent to instance 0x7f9250fa9e00'

首先在代码中放置一个异常断点 enter image description here

然后再次运行代码并查看引发异常的行。在你的情况下，由于在NSArray对象上调用了numberOfSectionsInTableView（这是一个tableView委托方法），似乎存在一些问题。

尝试使用异常断点并进行调试并查看。干杯。玩得开心

Answer 3

您的视图控制器必须符合此协议UITableViewDataSource：有两种方法是@required，您需要在代码中实现这些方法：

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;

但也有其他方法。您必须实施numberOfSectionsInTableView:

看一下delegate＆amp; datasource与所有情节提要中的viewcontroller或viewcontroller .m类
