Question

我试图在我的React Native iOS应用中使用Push Notifications。我按照教程PushNotificationsIOS进行了操作。我也手动链接了图书馆。

在AppDelegate.m文件中，如下所示，

#import "RCTPushNotificationManager.h"

#import "AppDelegate.h"

#import "RCTRootView.h"

@implementation AppDelegate

// Required to register for notifications
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
  [RCTPushNotificationManager didRegisterUserNotificationSettings:notificationSettings];
}
// Required for the register event.
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
  [RCTPushNotificationManager didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}
// Required for the notification event.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification
{
  [RCTPushNotificationManager didReceiveRemoteNotification:notification];
}

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

  /**
   * Loading JavaScript code - uncomment the one you want.
   *
   * OPTION 1
   * Load from development server. Start the server from the repository root:
   *
   * $ npm start
   *
   * To run on device, change `localhost` to the IP address of your computer
   * (you can get this by typing `ifconfig` into the terminal and selecting the
   * `inet` value under `en0:`) and make sure your computer and iOS device are
   * on the same Wi-Fi network.
   */

  //jsCodeLocation = [NSURL URLWithString:@"http://172.16.2.173:8081/index.ios.bundle?platform=ios&dev=true"];

  jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&dev=true"];

  /**
   * OPTION 2
   * Load from pre-bundled file on disk. The static bundle is automatically
   * generated by "Bundle React Native code and images" build step.
   */

  //jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"myapp"
                                               initialProperties:nil
                                                   launchOptions:launchOptions];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  return YES;
}

@end

但构建失败并出现错误，

No known class method for selector 'didRegisterUserNotificationSettings:'
No known class method for selector 'didRegisterForRemoteNotificationsWithDeviceToken:'
No known class method for selector 'didReceiveRemoteNotification:'

这是为什么？如何解决这个问题？

PS：注意

找到一个替代品，它工作正常。 Apple Push Notification Services in iOS 6 Tutorial
