上一篇[iOS Xcode]APNs_Apple Push Notification server(憑證製作)教大家如何申請APNs所需的憑證
接下來要開始教大家寫手機端的程式

這邊很簡單的就是讓大家去向APNs註冊，然後得到一組token

AppDelegate.m

先在application didFinishLaunchingWithOptions中設定APP可以接受哪些下訊息(例如：文字，紅色小圈圈，聲音)

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

// Override point for customization after application launch.

UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound |

UIUserNotificationTypeAlert | UIUserNotificationTypeBadge categories:nil];

    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

return YES;

}

然後在 didRegisterUserNotificationSettings向APNS註冊

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

    [[UIApplication sharedApplication] registerForRemoteNotifications];

}

傳回向APNS註冊的token，並顯示在NSLog上

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

NSLog(@"Token : %@",deviceToken);

}
最後只要有看到token出現就算是成功了！
