Question

我正在开发支持交互式通知的iOS8应用程序。但我不清楚交互式通知支持的功能以及如何发送/处理交互式通知。如果有人可以给出一个例子，那对我来说非常有帮助。

首先，您需要创建通知操作。
其次，您需要创建通知类别并设置其操作。您可以设置两个上下文。 UIUserNotificationActionContextDefault或UIUserNotificationActionContextMinimal
第三，您需要创建通知设置并指定上述类别
第四步是创建本地通知并为其分配类别的标识符。

UIMutableUserNotificationAction *notificationAction1 = [[UIMutableUserNotificationAction alloc] init];
notificationAction1.identifier = @"Accept";
notificationAction1.title = @"Accept";
notificationAction1.activationMode = UIUserNotificationActivationModeBackground;
notificationAction1.destructive = NO;
notificationAction1.authenticationRequired = NO;

UIMutableUserNotificationAction *notificationAction2 = [[UIMutableUserNotificationAction alloc] init];
notificationAction2.identifier = @"Reject";
notificationAction2.title = @"Reject";
notificationAction2.activationMode = UIUserNotificationActivationModeBackground;
notificationAction2.destructive = YES;
notificationAction2.authenticationRequired = YES;

UIMutableUserNotificationAction *notificationAction3 = [[UIMutableUserNotificationAction alloc] init];
notificationAction3.identifier = @"Reply";
notificationAction3.title = @"Reply";
notificationAction3.activationMode = UIUserNotificationActivationModeForeground;
notificationAction3.destructive = NO;
notificationAction3.authenticationRequired = YES;

UIMutableUserNotificationCategory *notificationCategory = [[UIMutableUserNotificationCategory alloc] init];
notificationCategory.identifier = @"Email";
[notificationCategory setActions:@[notificationAction1,notificationAction2,notificationAction3] forContext:UIUserNotificationActionContextDefault];
[notificationCategory setActions:@[notificationAction1,notificationAction2] forContext:UIUserNotificationActionContextMinimal];

NSSet *categories = [NSSet setWithObjects:notificationCategory, nil];

UIUserNotificationType notificationType = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:notificationType categories:categories];

[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10];
localNotification.alertBody = @"Testing";
localNotification.category = @"Email"; //  Same as category identifier
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

我想延长Sourav Gupta的答案。一旦您完成了Sourav解释的内容，您必须实现代理以接收推送通知操作。代表们是，

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void(^)())completionHandler {

// Handle actions of local notifications here. You can identify the action by using "identifier" and perform appropriate operations

     if(completionHandler != nil)    //Finally call completion handler if its not nil
         completionHandler();
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler {

// Handle actions of remote notifications here. You can identify the action by using "identifier" and perform appropriate operations

     if(completionHandler != nil)    //Finally call completion handler if its not nil
         completionHandler();
}
