registerForRemoteNotifications在iOS9上有效，在iOS8上失败

Question

For the user to allow badge / sound / alert and to get the notification token, I use the simple and classic code (for iOS >= 8) in the application:didFinishLaunchingWithOptions:

UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];

After calling this code on an iOS9 device, the didRegisterForRemoteNotificationsWithDeviceToken: callback is called and I get my token.

But running the exact same code, same bundleId, on an iOS8 device gives me an error (through the didFailToRegisterForRemoteNotificationsWithError: callback).

The error is the "no valid 'aps-environment' entitlement string found for application", which doesn't make sense in this case because it's working fine on iOS9!

仅在通过Xcode在设备上部署应用程序时才发生此问题，当使用企业证书部署OTA时，它按预期工作：/
