【问题描述】：

我在 ios 中有一个应用程序，我在其中向用户发送快速调查。我想利用 iOS 8 中的新功能，用户可以直接在推送通知上进行交互。用户将收到调查问题并做出回应。

我知道您必须在启动应用程序时构建您的操作和类别。我已经编写了我的代码，并且到目前为止已经能够成功执行此操作。

现在，操作按钮上的文本会根据调查问题而改变。我在发送的 JSON 中包含了操作按钮的键和文本，但在收到通知时我无法更改操作按钮的标题。

有没有办法做到这一点？这是我的代码：

我定义全局变量：

//This will help configure the interactive notifications, so that the user can reply to push notification from out of the app
NSString * const notificationCategoryIdent  = @"SURVEY";
NSString * const notificationActionPositiveButton = @"POSITIVE_BUTTON";
NSString * const notificationActionNegativeButton = @"NEGATIVE_BUTTON";

在我的 AppDelegate 中：

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

if(pushNotificationPayload) 

    urlPushData2 = @"Application was closed";
    [self application:[UIApplication sharedApplication] didReceiveRemoteNotification:pushNotificationPayload];



//Registrar tipos de aviso para Push Notifications
//if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
if ([[[UIDevice currentDevice] systemVersion] floatValue] < 8.0) //Before iOS 8
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIUserNotificationTypeBadge |
                                                                           UIUserNotificationTypeSound |
                                                                           UIUserNotificationTypeAlert)];

else 

    // define notification actions (In case of categorized remote push notifications)
    positiveButton = [[UIMutableUserNotificationAction alloc] init];
    [positiveButton setActivationMode:UIUserNotificationActivationModeForeground];
    [positiveButton setTitle:notificationActionPositiveButton];
    [positiveButton setIdentifier:notificationActionPositiveButton];
    [positiveButton setDestructive:NO];
    // this action wil be executed without necessity of passcode authentication (if locked)
    [positiveButton setAuthenticationRequired:NO];

    negativeButton = [[UIMutableUserNotificationAction alloc] init];
    [negativeButton setActivationMode:UIUserNotificationActivationModeForeground];
    [negativeButton setTitle:notificationActionNegativeButton];
    [negativeButton setIdentifier:notificationActionNegativeButton];
    [negativeButton setDestructive:NO];
    // this action wil be executed without necessity of passcode authentication (if locked)
    [negativeButton setAuthenticationRequired:NO];

    // define Categories (In case of categorized remote push notifications)
    UIMutableUserNotificationCategory *actionCategory;
    actionCategory = [[UIMutableUserNotificationCategory alloc] init];
    [actionCategory setIdentifier:notificationCategoryIdent];
    [actionCategory setActions:@[positiveButton, negativeButton]
                    forContext:UIUserNotificationActionContextDefault];


    NSSet *categories = [NSSet setWithObject:actionCategory];

    UIUserNotificationType types = (UIUserNotificationTypeAlert|
                                    UIUserNotificationTypeSound|
                                    UIUserNotificationTypeBadge);

    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types
                                                 categories:categories];

    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

    [[UIApplication sharedApplication] registerForRemoteNotifications];



//Boolean value for temporary app interruptions
temporaryInactivity = FALSE;

return YES;

                                                                        preferredStyle:UIAlertControllerStyleAlert];
            UIAlertAction *Cancel = [UIAlertAction actionWithTitle:@"No"
                                                             style:UIAlertActionStyleDefault
                                                           handler:^(UIAlertAction *action)

            UIAlertAction *OK = [UIAlertAction actionWithTitle:@"Sí"
                                                         style:UIAlertActionStyleDefault
                                                       handler:^(UIAlertAction *action)

                                                           self.url = [[NSUserDefaults standardUserDefaults] objectForKey:@"pushNotificationURL"];
                                                           self.urlName = [[NSUserDefaults standardUserDefaults] objectForKey:@"pushNotificationURLName"];

     else 
        [UIApplication sharedApplication].applicationIconBadgeNumber = [UIApplication sharedApplication].applicationIconBadgeNumber - 1;
        //self.url = [[NSUserDefaults standardUserDefaults]objectForKey:@"pushNotificationURL"];
        self.url = urlPushData2;
        self.urlName = alert;
        [self setupNavigationControllerApp];
    





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

if ([identifier isEqualToString:notificationActionPositiveButton]) 

    //Testing the action button
    self.url = @"http://www.google.com";
    self.urlName = @"hello";
    [self setupNavigationControllerApp];


else if ([identifier isEqualToString:notificationActionNegativeButton]) 

    //Testing the action button
    self.url = @"http://www.yahoo.com";
    self.urlName = @"goodbye";
    [self setupNavigationControllerApp];



// Must be called when finished
completionHandler();

这是我的 JSON：

"aps":
       "alert":"Who's your favorite pop singer?",
        "badge":1,
        "sound":"default",
        "category":"SURVEY",
        "positiveButton":"Katy Perry",
        "negativeButton":"Miley Cyrus"
        ,
 "url":"http://www.pretechmobile.com",
 "url2":"http://goo.gl/U9p1y"
 

【参考方案1】：

很抱歉，您不能动态更改按钮的标题。它们与您注册通知时所存储的类别相关联。

一种可能的解决方法是在消息文本中显示两个选项，分别标有“A”和“B”，并让您的按钮标题为“选项 A”和“选项 B”。像这样的：

---------------------------------
|Who's your favorite pop singer?|
|A: Katy Perry    B: Miley Cyrus|
---------------------------------
|   Option A    |   Option B    |
---------------------------------

此外，如果您有是/否问题，您可以使用“是”和“否”选项为他们创建一个类别，并使用此类别标记您的通知。

我希望这会有所帮助。

这确实有帮助！谢谢你，好主意！

只有当应用程序在前台时，我才能更新按钮标题。
