I\'m currently creating an app that needs to receive push notifications from a server.
When I got the device token, I send it to my server and save it into DB,
M
I found answered of my question.
Never use your NSUserDefaults' key as @"key".
For example what I have previously used.
[[NSUserDefaults standardUserDefaults] setObject:deviceToken forKey:@"key"];
[[NSUserDefaults standardUserDefaults] synchronize];
And what I am using now.
[[NSUserDefaults standardUserDefaults] setObject:deviceToken forKey:@"token"];
[[NSUserDefaults standardUserDefaults] synchronize];
And now push notification is coming as it is.
So conclusion is never used your key name @"key". I don't know why but may be some preference is using this @"key" by default.
Thanks.
