【问题描述】：

在 ios 10.3 中，我将代码添加到 AppDelegate:

@interface AppDelegate () 
    UNUserNotificationCenter *center;


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 

    center = [UNUserNotificationCenter currentNotificationCenter];
    UNAuthorizationOptions options = UNAuthorizationOptionAlert + UNAuthorizationOptionSound;
    [center requestAuthorizationWithOptions:options
                          completionHandler:^(BOOL granted, NSError * _Nullable error) 
                              if (!granted) 
                                  DLog(@"Something went wrong");
                               else 
                                  DLog(@"Access Granted")
                              
                          ];

    return YES;

我点击了通知，但是下面的方法没有被调用。

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification

【参考方案1】：

在AppDelegate注册通知导入UserNotifications/UserNotifications.h框架，并在收到通知时使用通知代理UNUserNotificationCenterDelegate响应通知。

@interface AppDelegate ()<UNUserNotificationCenterDelegate>

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
    // Override point for customization after application launch.

    //Notification Setup.
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10.0) 
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error)
            if( !error )
                [[UIApplication sharedApplication] registerForRemoteNotifications];
            
        ];
     else 

        //register to receive notifications
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

    


    return YES;
