本文介绍了didReceiveRemoteNotification 未调用，iOS 10的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在 iOS 9.3 中，didReceiveRemoteNotification 方法在以下两种情况下都会被调用.

1) 收到推送通知时2) 当用户通过点击通知启动应用时.

但在 iOS 10 上，我注意到 didReceiveRemoteNotification 方法在用户通过点击通知启动应用程序时不会触发.只有在收到通知时才会调用它.因此，从通知启动应用程序后，我无法执行任何进一步操作.

应该怎么解决这个问题?有什么想法吗?

解决方案

类型转换

适用于 Swift3

示例见这个

<块引用>

导入UserNotifications框架并在Appdelegate中添加UNUserNotificationCenterDelegate

导入用户通知@UIApplicationMain类 AppDelegate:UIResponder、UIApplicationDelegate、UNUserNotificationCenterDelegatefunc application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) ->布尔{//在应用程序启动后覆盖自定义点.//创建通知中心让中心 = UNUserNotificationCenter.current()center.delegate = 自己//设置类型为声音或徽章center.requestAuthorization(options: [.sound,.alert,.badge, .providesAppNotificationSettings]) { (granted, error) in//根据授权启用或禁用功能}application.registerForRemoteNotifications()返回真}func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {//let chars = UnsafePointer((deviceToken as NSData).bytes)var 标记 = ""对于 i 在 0..

<块引用>

使用这个委托接收通知

 func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (_ options: UNNotificationPresentationOptions) -> Void) {print("处理从前台推送")//当应用程序在前台时处理推送的自定义代码打印(\(notification.request.content.userInfo)")}func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping() -> Void) {打印(处理从后台推送或关闭")//如果你在 didReceiveRemoteNotification 中设置了一个成员变量，你就会知道这是来自关闭的还是后台的打印(\(response.notification.request.content.userInfo)")}func userNotificationCenter(_ center: UNUserNotificationCenter, openSettingsFor notification: UNNotification?) {让 navController = self.window?.rootViewController as！导航控制器让 notificationSettingsVC = NotificationSettingsViewController()navController.pushViewController(notificationSettingsVC，动画:真)}

目标 C

AppDelegate.h 有以下几行:

第一步

//在你的项目UserNotifications"中添加框架#import @interface AppDelegate : UIResponder

第 2 步

AppDelegate.m

//定义宏#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)

第 3 步

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {application.applicationIconBadgeNumber = 0;如果(SYSTEM_VERSION_LESS_THAN(@10.0")){[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeprovidesAppNotificationSettings) category:nil]];[[UIApplication sharedApplication] registerForRemoteNotifications];//如果(选项！=零)//{//NSLog( @"registerForPushWithOptions:" );//}} 别的 {UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];center.delegate = self;[中心 requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL 授予，NSError * _Nullable 错误) {如果(！错误){//需要让应用对推送通知做任何事情[[UIApplication sharedApplication] registerForRemoteNotifications];NSLog( @"推送注册成功" );} 别的 {NSLog( @"推送注册失败" );NSLog( @"ERROR: %@ - %@", error.localizedFailureReason, error.localizedDescription );NSLog( @"SUGGESTIONS: %@ - %@", error.localizedRecoveryOptions, error.localizedRecoverySuggestion );}}];}返回是；}

<块引用>

这将作为调用 registerForRemoteNotifications 的结果触发:

 - (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{//我们为向 AWS 中间人注册设备而执行的自定义操作}

<块引用>

然后，当用户点击通知时，会触发:

当应用程序处于前台或后台但未关闭时，这将在 iOS 10 中触发

 -(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void(^)(UIBackgroundFetchResult))completionHandler{//iOS 10 将通过其他方法处理通知如果(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@10.0")){NSLog( @"iOS version >= 10. 让 NotificationCenter 处理这个.");//设置一个成员变量来告诉新委托这是背景返回;}NSLog( @"HANDLE PUSH, didReceiveRemoteNotification: %@", userInfo );//自定义代码来处理通知内容if( [UIApplication sharedApplication].applicationState == UIApplicationStateInactive ){NSLog( @"INACTIVE" );完成处理程序( UIBackgroundFetchResultNewData )；}else if( [UIApplication sharedApplication].applicationState == UIApplicationStateBackground ){NSLog(@"背景");完成处理程序( UIBackgroundFetchResultNewData )；}别的{NSLog(@"前景");完成处理程序( UIBackgroundFetchResultNewData )；}}

或使用

 - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{[自我应用程序:应用程序 didReceiveRemoteNotification:userInfo fetchCompletionHandler:^(UIBackgroundFetchResult 结果) {}];}

<块引用>

那么对于iOS 10，这两个方法:

- (void)userNotificationCenter:(UNUserNotificationCenter *)centerwillPresentNotification:(UNNotification *)通知withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{NSLog(@"处理前台推送");//当应用程序在前台时处理推送的自定义代码NSLog(@"%@", notification.request.content.userInfo);}- (void)userNotificationCenter:(UNUserNotificationCenter *)centerdidReceiveNotificationResponse:(UNNotificationResponse *)responsewithCompletionHandler:(void (^)())completionHandler{NSLog(@"处理后台推送或关闭");//如果你在 didReceiveRemoteNotification 中设置了一个成员变量，你就会知道这是来自关闭的还是后台的NSLog(@"%@", response.notification.request.content.userInfo);}- (void)userNotificationCenter:(UNUserNotificationCenter *)centeropenSettingsForNotification:(UNNotification *)notification{在应用程序中打开通知设置屏幕}

In iOS 9.3, the didReceiveRemoteNotification method gets called on both of the following occasions.

1) When the push notification is received 2) When the user launches the app by tapping on the notification.

But on iOS 10, I notice that the didReceiveRemoteNotification method does NOT fire when the user launches the app by tapping on the notification. It's called only when the notification is received. Hence, I cannot do any further action after the app is launched from notification.

What should be the fix for this? Any idea?

解决方案

type converson

for Swift3

-

for sample see this

import the UserNotifications framework and add the UNUserNotificationCenterDelegate in Appdelegate

import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate  


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    //create the notificationCenter
    let center  = UNUserNotificationCenter.current()
    center.delegate = self
    // set the type as sound or badge
    center.requestAuthorization(options: [.sound,.alert,.badge,  .providesAppNotificationSettings]) { (granted, error) in
        // Enable or disable features based on authorization

        }
        application.registerForRemoteNotifications()

    return true
}


 func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
 // let chars = UnsafePointer<CChar>((deviceToken as NSData).bytes)
  var token = ""

  for i in 0..<deviceToken.count {
//token += String(format: "%02.2hhx", arguments: [chars[i]])
   token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
  }

  print("Registration succeeded!")
  print("Token: ", token)
 }

 func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
  print("Registration failed!")
 }

receive the Notifications using this delegates

 func userNotificationCenter(_ center: UNUserNotificationCenter,  willPresent notification: UNNotification, withCompletionHandler   completionHandler: @escaping (_ options:   UNNotificationPresentationOptions) -> Void) {
    print("Handle push from foreground")
    // custom code to handle push while app is in the foreground
    print("\(notification.request.content.userInfo)")
 }

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    print("Handle push from background or closed")
    // if you set a member variable in didReceiveRemoteNotification, you  will know if this is from closed or background
    print("\(response.notification.request.content.userInfo)")
}

func userNotificationCenter(_ center: UNUserNotificationCenter, openSettingsFor notification: UNNotification?) {
let navController = self.window?.rootViewController as! UINavigationController
let notificationSettingsVC = NotificationSettingsViewController()
navController.pushViewController(notificationSettingsVC, animated: true)
}

for more Information you can see in Apple API Reference

objective C

AppDelegate.h has these lines:

Step-1

//Add Framework in your project "UserNotifications"
#import <UserNotifications/UserNotifications.h>  
@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>

Step-2

AppDelegate.m

  // define macro
  #define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)  
  #define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)

Step-3

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
application.applicationIconBadgeNumber = 0;
    if( SYSTEM_VERSION_LESS_THAN( @"10.0" ) ) {  
        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound |    UIUserNotificationTypeAlert | UIUserNotificationTypeBadge |  UIUserNotificationTypeprovidesAppNotificationSettings) categories:nil]];  
        [[UIApplication sharedApplication] registerForRemoteNotifications];  

        //if( option != nil )  
        //{  
        //    NSLog( @"registerForPushWithOptions:" );  
        //}  
    } else {  
      UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];  
      center.delegate = self;  
      [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if( !error ) {
            // required to get the app to do anything at all about push notifications  
            [[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;
}

This will fire as a result of calling registerForRemoteNotifications:

 - (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken  
{  
// custom stuff we do to register the device with our AWS middleman  
 }

Then, when a user taps a notification, this fires:

This will fire in iOS 10 when the app is foreground or background, but not closed 

 -(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void  
  (^)(UIBackgroundFetchResult))completionHandler  
  {  
// iOS 10 will handle notifications through other methods  

if( SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO( @"10.0" ) )  
{  
  NSLog( @"iOS version >= 10. Let NotificationCenter handle this one." );  
 // set a member variable to tell the new delegate that this is background  
  return;  
}  
NSLog( @"HANDLE PUSH, didReceiveRemoteNotification: %@", userInfo );  

// custom code to handle notification content  

if( [UIApplication sharedApplication].applicationState == UIApplicationStateInactive )  
{  
  NSLog( @"INACTIVE" );  
  completionHandler( UIBackgroundFetchResultNewData );  
}  
else if( [UIApplication sharedApplication].applicationState == UIApplicationStateBackground )  
{  
  NSLog( @"BACKGROUND" );  
  completionHandler( UIBackgroundFetchResultNewData );  
}  
else  
{  
  NSLog( @"FOREGROUND" );  
  completionHandler( UIBackgroundFetchResultNewData );  
}  
}

or use 

  - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo  
{  
[self application:application didReceiveRemoteNotification:userInfo fetchCompletionHandler:^(UIBackgroundFetchResult result) {  
}];  
}

Then for iOS 10, these two methods:

- (void)userNotificationCenter:(UNUserNotificationCenter *)center  
    willPresentNotification:(UNNotification *)notification  
  withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler  
    {  
  NSLog( @"Handle push from foreground" );  
  // custom code to handle push while app is in the foreground  
    NSLog(@"%@", notification.request.content.userInfo);
   }  

- (void)userNotificationCenter:(UNUserNotificationCenter *)center  
didReceiveNotificationResponse:(UNNotificationResponse *)response  
  withCompletionHandler:(void (^)())completionHandler  
   {  
     NSLog( @"Handle push from background or closed" );  
     // if you set a member variable in didReceiveRemoteNotification, you  will know if this is from closed or background  
     NSLog(@"%@", response.notification.request.content.userInfo);
    }  

    - (void)userNotificationCenter:(UNUserNotificationCenter *)center 
   openSettingsForNotification:(UNNotification *)notification{
        Open notification settings screen in app
   }
