registerForRemoteNotificationTypes不能正常工作iOS7 xcode 6

Question

I have an issue after upgrading our app to work with iOS 8, where registerForRemoteNotificationTypes does not appear to be working on phone running iOS 7, as in didRegisterForRemoteNotificationsWithDeviceToken does not get called and the "Allow Push Notifications" dialog is not appearing on the app. This is the code I am using

// Add registration for remote notifications
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    NSLog(@"iOS 8 Registering for remote notification");
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
} else {
    NSLog(@"Registering for remote notification");
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}

This code works fine for phones running iOS 8, just not iOS 7. One other bit of information we managed to get push notifications to work on an iOS 7 phone only after running the app through xcode with the phone attached. We then deployed the same code as an ad Hoc deployment to another iPhone and iPad running iOS 7 and neither worked. Is there something obvious I am missing here.

Try this code, may work for you.

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary   *)launchOptions
{
if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
// iOS 8 Notifications
[application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

[application registerForRemoteNotifications];
}
else
{
// iOS < 8 Notifications
[application registerForRemoteNotificationTypes:
 (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
}
return YES;
}

I noticed that XCode 6 appears to generate it's own provisioning profiles labeled with XC these also appear in the provisioning profiles of the developer account. When you export the app for ad Hoc release it uses one of these profiles and there appears to be no way to select the profile you created and set in the build setting. It appears it was using a wild card profile that had push notification turned off. I managed to export again with a profile that seemed to be based on one I created with push turn on and it started working. This would explain why I managed to get it to work if I loaded the app directly to the phone from Xcode.

I got hit the same problem. In my situation, it turns a simple problem. You should examine your notification setting first. Going to Setting/Notification Center, and check whether the notification type you set in your code are opened. Hoping that can help you!

是的，代码是非常正确的，但要在您的设备上获取默认通知警报，首先重置模拟器的内容并重新安装应用程序。我试过这个并在模拟器上也运行良好。
