调用unregisterForRemoteNotifications后，registerForRemoteNotifications不起作用 [英] registerForRemoteNotifications is not working after calling unregisterForRemoteNotifications

问题描述

[[UIApplication sharedApplication] registerForRemoteNotifications];

呼叫

后

无法正常工作

[[UIApplication sharedApplication] unregisterForRemoteNotifications];

知道为什么吗? 官方文件评论说:通过此方法取消注册的应用程序始终可以重新注册.

解决方案

您应该只卸载应用程序并删除该代码！

也不要取消注册远程通知.这显然不是一个好方法.因此，请修改此行:-

[[UIApplication sharedApplication] unregisterForRemoteNotifications]

这会将应用置于不稳定状态，在该状态下调用registerForRemoteNotifications不再起作用.

您只需在代码中调用一次即可.

[[UIApplication sharedApplication] registerForRemoteNotifications]

[[UIApplication sharedApplication] registerForRemoteNotifications];

is not working after calling

[[UIApplication sharedApplication] unregisterForRemoteNotifications];

any idea why? official document commented that:Apps unregistered through this method can always re-register.

解决方案

You should just Uninstall the app and delete that code!

Also do not unregister the remote notifications. This is obviously not a good way to do.So revue this line :-

[[UIApplication sharedApplication] unregisterForRemoteNotifications]

It puts the app in an unstable state where calling registerForRemoteNotifications no longer works.

All you have to call it once in your code.

[[UIApplication sharedApplication] registerForRemoteNotifications]
