注册Parse通知iOS7和iOS8,编译器警告

Question

我已经编写了我的应用程序以在iOS8中接收Parse通知,并且最近发现这些在iOS中无法运行,因此必须在AppDelegate.m中将我的代码更改为如下:

viewDidLoad中:

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
        NSLog(@"Requesting permission for push notifications...iOS8"); // iOS 8
        UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                        UIUserNotificationTypeBadge |
                                                        UIUserNotificationTypeSound);
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil];
        [application registerUserNotificationSettings:settings];
        [application registerForRemoteNotifications];
    } else {
        NSLog(@"Registering device for push notifications..."); // iOS 7 and earlier
        [UIApplication.sharedApplication registerForRemoteNotificationTypes:
         UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge |
         UIRemoteNotificationTypeSound];
    }

和:

- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // Store the deviceToken in the current Installation and save it to Parse.
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setDeviceTokenFromData:deviceToken];
    [currentInstallation saveInBackground];
}

我测试了两个版本的iOS,它似乎工作正常.但是,如果我将Xcode中的部署目标更改为iOS8或更高版本,我会收到以下编译器警告:

AppDelegate.m:62:10: 'UIRemoteNotificationTypeAlert' is deprecated: first deprecated in iOS 8.0 - Use UIUserNotificationType for user notifications and registerForRemoteNotifications for receiving remote notifications instead.

AppDelegate.m:62:42: 'UIRemoteNotificationTypeBadge' is deprecated: first deprecated in iOS 8.0 - Use UIUserNotificationType for user notifications and registerForRemoteNotifications for receiving remote notifications instead.

AppDelegate.m:63:10: 'UIRemoteNotificationTypeSound' is deprecated: first deprecated in iOS 8.0 - Use UIUserNotificationType for user notifications and registerForRemoteNotifications for receiving remote notifications instead.

/AppDelegate.m:61:42: 'registerForRemoteNotificationTypes:' is deprecated: first deprecated in iOS 8.0 - Please use registerForRemoteNotifications and registerUserNotificationSettings: instead

看到这些警告是否正常,是否因为我在更高的部署目标中工作？或者我必须在某处更改代码？似乎很奇怪我必须看到这些警告.任何指针都会非常感激.谢谢!

如果您将部署目标更改为iOS 8,那么无需检查iOS 8(在iOS 8之前,因为您的应用程序仅适用于iOS 8设备),这就是为什么它会为您提供这些警告.所以只需这样注册:

[application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
