ios 9でiphoneデバイストークンを取得する方法

Question

私はAPNSを練習したいので、デバイストークンを取得する必要があります。
しかし、私は私のiPhone 5を使用してデバイストークンを取得できません。
更新された別のiphoneを使用すると、デバイストークンが正常に取得されます。
どうすればよいですか？

これは私のコードです：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 

    //APNS setting 

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]){ 

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

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{ 

NSString *key = @"once"; 

BOOL onceShowed = [[NSUserDefaults standardUserDefaults] boolForKey:key]; 
if (!onceShowed){ 
     // upload device token to my sever  
} 
} 

-(void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings{ 

[application registerForRemoteNotifications]; 
} 

ありがとう！

ステップ2でプッシュ通知のために登録します。このコードを試してみてください。

(BOOL)application:(UIApplication *)application 
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{  
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) 
    { 
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]]; 
    [[UIApplication sharedApplication] registerForRemoteNotifications]; 
    } 
    else 
    { 
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: 
    (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)]; 
    } 

- (void)application:(UIApplication *)application 
didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings 
{ 
    [application registerForRemoteNotifications]; 
} 

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken 
{ 
    NSLog(@"deviceToken: %@", deviceToken); 
    NSString * token = [NSString stringWithFormat:@"%@", deviceToken]; 
    //Format token as you need: 
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""]; 
    token = [token stringByReplacingOccurrencesOfString:@">" withString:@""]; 
    token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""]; 
}
