当应用程序未运行时处理推送通知（即完全死亡）

Question

我可以将推送通知发送到我的IOS设备。但是当我点击该通知时，它只是打开应用程序。应用程序内没有显示任何消息。由我使用

代码：

if (application.applicationState == UIApplicationStateActive) { 

    NSString *cancelTitle = @"Close"; 

    NSString *showTitle = @"Show"; 

    NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; 

    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Some title" 

                 message:message 

                 delegate:self 

               cancelButtonTitle:cancelTitle 

               otherButtonTitles:showTitle, nil]; 

    [alertView show]; 

    [alertView release]; 

} else { 

    //Do stuff that you would do if the application was not active 

} 

但无法显示我的消息，以上代码的帮助。上述代码仅适用于我的应用程序处于前台状态的情况下打开，而不是仅此警报才会显示。

请帮忙。

谢谢。

Answer 1

处理这种事情的最好方法是在APN中使用深度链接。这将让您嵌入数据，然后可以在您的应用程序中处理数据，并将用户引导至特定事件。

否则，您仅限于使用应用程序委托中的ApplicationDidEnterForeground方法。只要把你的alertView代码放在那里，任何时候你的应用程序都会被放到前台运行。

从苹果文档

https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/Introduction.html

“当你的应用程序必须启动以 收到通知，UIKit中包括推出 UIApplicationLaunchOptionsLocalNotificationKey或 UIApplicationLaunchOptionsRemoteNotificationKey关键 选项字典传递给你的应用程序代理的 应用程序：willFinishLaunchingWithOptions：和 应用程序：didFinishLaunchingWithOptio ns：方法。 这些密钥的存在让你知道，有通知数据等待 处理，并让你有机会适当地配置你的应用程序的界面 。不过，您不需要在这些 方法中处理通知。在您的应用运行后，UIKit会调用您的应用委托的其他方法 ，例如 应用：didReceiveLocalNotification：方法，以便为您提供处理通知数据的 机会。这方法被称为 取决于哪些方法您实现与用户 是否与该消息的系统UI交互。”

所以，请检查您的应用程序已经启动，由于通知，如果是这样显示的对话框

我认为有一个简单的解决方案。

1. 可以存储一些标志的应用程序，一旦当您收到 通知，您可以检查该怎么办呢here
2. 后，关于你当你从后台 也许像here
检测

如果你想，当你从通知打开应用程序，只显示警报，那么也许你这是你solution

当应用程序未运行（或完全死亡）时处理推送通知

我发布此解决方案，因为它为我工作。

转到您的AppDelegate.m文件。

步骤1： 写入这个函数内的代码：

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

    UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; 

if (localNotif) { 

     NSString *cancelTitle = @"Close"; 
     NSString *showTitle = @"OK"; 
     NSString *message = [[localNotif valueForKey:@"aps"] valueForKey:@"alert"]; 
     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Message Received" 
                  message:message 
                  delegate:self 
                cancelButtonTitle:cancelTitle 
                otherButtonTitles:showTitle, nil]; 
     [alertView show]; 


    } 

} 

步骤2：

插入该全码：

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo 
{ 

NSLog(@"%s..userInfo=%@",__FUNCTION__,userInfo); 

/** 
    * Dump your code here according to your requirement after receiving push 
    */ 

    if (application.applicationState == UIApplicationStateActive) { 
     NSString *cancelTitle = @"Close"; 
     NSString *showTitle = @"OK"; 
     NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; 
     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Message Received" 
                  message:message 
                  delegate:self 
                cancelButtonTitle:cancelTitle 
                otherButtonTitles:showTitle, nil]; 
     [alertView show]; 

    } 

    else if(application.applicationState == UIApplicationStateBackground){ 

     //app is in background, if content-available key of your notification is set to 1, poll to your backend to retrieve data and update your interface here 


     NSString *cancelTitle = @"Close"; 
     NSString *showTitle = @"OK"; 
     NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; 
     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Message Received" 
                  message:message 
                  delegate:self 
                cancelButtonTitle:cancelTitle 
                otherButtonTitles:showTitle, nil]; 
     [alertView show]; 

    } 


    else if(application.applicationState == UIApplicationStateInactive){ 

     //app is in background, if content-available key of your notification is set to 1, poll to your backend to retrieve data and update your interface here 


     NSString *cancelTitle = @"Close"; 
     NSString *showTitle = @"OK"; 
     NSString *message = [[userInfo valueForKey:@"aps"] valueForKey:@"alert"]; 
     UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Message Received" 
                  message:message 
                  delegate:self 
                cancelButtonTitle:cancelTitle 
                otherButtonTitles:showTitle, nil]; 
     [alertView show]; 

    } 


} 

这整个代码将工作，无论是应用程序有效，无效或完全死亡。它会为您提供推送消息的AlertView。

当应用程序被完全杀死GET通知代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
if (launchOptions != nil) 
{ 
    //opened from a push notification when the app is closed 
    NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; 
    if (userInfo != nil) 
    { 
     NSLog(@"userInfo->%@",[userInfo objectForKey:@"aps"]); 
     //write you push handle code here 

    } 

} 
}
