ios - How to use the device token in method other than didRegisterForRemoteNotificationsWithDeviceToken?

Question

I got the device token through didRegisterForRemoteNotificationsWithDeviceToken method. I wanted to use the device token in another method. I tried it in this way,

In didRegisterForRemoteNotificationsWithDeviceToken method:

str = [NSString stringWithFormat:@"%@",deviceToken];
// str is the NSString which is declared in the appDelegate.h file as global variable

In didReceiveRemoteNotification method:

 NSLog(@"Device Token : %@",str);  

When i do like this the Device Token is returning as "nosniff".

How can i store this device token in a global variable and use it in the other class or in other method.

You can add the device token to the NSUserDefaults dictionary like so:

-(void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    [[NSUserDefaults standardUserDefaults] setObject:deviceToken forKey:@"deviceToken"];

This can then be accessed in other methods like so:

NSString *deviceToken = [[NSUserDefaults standardUserDefaults] objectForKey:@"deviceToken"];
