我在iOS 10和iPhone中遇到问题。获取推送通知警报两次。请查看以下视频。

我在willPresentNotification和didReceiveNotificationResponse通知委托方法中编写了类似的代码。我在这两种方法中都有任何变化，因为我没有遇到iPad的问题。

我们将不胜感激。

在iOS 10中，我们需要在appDelegate UNUserNotificationCenter方法中调用didFinishLaunchingWithOptions。

您必须导入UserNotifications.framework并在UNUserNotificationCenterDelegate

中添加Appdelegate

<强> AppDelegate.h

#import <UIKit/UIKit.h>
#import <UserNotifications/UserNotifications.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>

@property (strong, nonatomic) UIWindow *window;

@end

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
   if([[[UIDevice currentDevice]systemVersion]floatValue]<10.0)
   {
      [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound |    UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
      [[UIApplication sharedApplication] registerForRemoteNotifications];
   }
   else
   {
      UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
      center.delegate = self;
      [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error)
      {
         if( !error )
         {
             [[UIApplication sharedApplication] registerForRemoteNotifications];
             NSLog( @"Push registration success." );
         }
         else
         {
             NSLog( @"Push registration FAILED" );
             NSLog( @"ERROR: %@ - %@", error.localizedFailureReason, error.localizedDescription );
             NSLog( @"SUGGESTIONS: %@ - %@", error.localizedRecoveryOptions, error.localizedRecoverySuggestion );  
         }  
     }];  
   }
  return YES;
}

我发现了错误。我在两个委托方法中编写相同的代码并获取内容可用：有效负载中的1个参数导致两个方法在前台触发的问题。这导致应用程序为单个推送通知显示两个警报。
