启用通知

Question

我想在我的iphone应用中启用通知。所以，我在应用ID中修改：

之后，我再次生成开发和分发配置文件并安装在我的xcode中。

我的应用是基于标签的应用，第一个标签是UITableViewController

我添加以下行：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{    
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];

   return YES;
}

所以，我想我应该将我的应用程序放在我的iphone中安装了通知的应用程序列表中，但它不是。

我是否错过了一些步骤？

Answer 1

首先在app delegate中启用远程通知。见下文：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];

    // Let the device know we want to receive push notifications
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
        (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

    return YES;
}

Answer 2

是的。根据{{​​3}}和this，您应该在registerForRemoteNotificationTypes中添加didFinishLaunchingWithOptions方法，该方法应如下所示：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{    
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];

    return YES;
}

根据您注册的类型，您的应用将显示在通知部分，您可以打开和关闭不同的类型（声音，徽章，横幅）。

希望有所帮助。
