iOS8でのPush通知対応

APNSへの登録

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // プッシュ許可の確認を表示
    if(NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_7_1){
        // iOS8以降
        UIUserNotificationType types =  UIUserNotificationTypeBadge |
                                        UIUserNotificationTypeSound |
                                        UIUserNotificationTypeAlert;
        UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
        [application registerUserNotificationSettings:mySettings];
    }else{
        // iOS8以前
        [application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
    }
}

デバイストークンの受け取り

// iOS8以降ここを通る
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:
(UIUserNotificationSettings *)notificationSettings{
    // これ呼ばないとデバイストークン取得できない
    [application registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // デバイストークン取得完了
    NSString *token = deviceToken.description;
    token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
    token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];

    // トークンをサーバに保存する処理など
    [self sendToken:token];
}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    // APNSへの登録失敗
}
