You could save the token in NSUSerDefaults

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
 
    NSString *str = [NSString
        stringWithFormat:@"Device Token=%@",deviceToken];
    NSLog(str);

   NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:str forKey:@"token"];
    [defaults synchronize];
 
}

Open in new window


Then read the defaults.

-(IBAction)buttonclick:(id)sender
{
      // Now what i write to get device token?
       NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
       NSLog(@"%@",[defaults objectForKey:@"token"]);
}

Open in new window
