调用didReceiveRemoteNotification当应用程序正在启动的第一次(Callin

我已经实现了我的didReceiveRemoteNotification方法。 它的工作原理，并显示与通过传递的通知数据的视图控制器。 这只能当应用程序已经在前台或者如果它是在后台运行。 然而，当应用程序不运行，用户点击的通知，应用程序启动，但它看起来好像没有通知已收到。 通知不被写入到文本文件和视图 - 控制不被按下。

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    if ( application.applicationState == UIApplicationStateActive)
    {
        NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];

        NSString *alertMsg = @"";
        NSString *badge = @"";
        NSString *sound = @"";
        NSString *custom = @"";

        if( [apsInfo objectForKey:@"alert"] != NULL)
        {
            alertMsg = [apsInfo objectForKey:@"alert"];
        }


        if( [apsInfo objectForKey:@"badge"] != NULL)
        {
            badge = [apsInfo objectForKey:@"badge"];
        }


        if( [apsInfo objectForKey:@"sound"] != NULL)
        {
            sound = [apsInfo objectForKey:@"sound"];
        }

        if( [userInfo objectForKey:@"Type"] != NULL)
        {
            custom = [userInfo objectForKey:@"Type"];
        }

        // Set your appending text.
        NSString *textToAdd = [NSString stringWithFormat:@":%@", alertMsg];

        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSString *fileName = [NSString stringWithFormat:@"%@/AccountNotifications.txt", documentsDirectory];
        NSString *fileContents = [[NSString alloc]  initWithContentsOfFile:fileName usedEncoding:nil error:nil];

        NSString *textToFile;

        if (fileContents == NULL)
        {
            textToFile = alertMsg;
        }

        // Here you append new text to the existing one
        if (fileContents != NULL)
        {
            textToFile = [fileContents stringByAppendingString:textToAdd];
        }

        // Here you save the updated text to that file
        paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        documentsDirectory = [paths objectAtIndex:0];
        fileName = [NSString stringWithFormat:@"%@/AccountNotifications.txt", documentsDirectory];
        NSString *content = textToFile;
        [content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];

        NSArray *fileData = [textToFile componentsSeparatedByString:@":"];

        NSMutableArray *tableDataFromFile;
        tableDataFromFile = [[NSMutableArray alloc] init];

        int i = 0;

        for (i = 1; i < [fileData count]; i++)
        {
            [tableDataFromFile addObject:fileData[i]];
        }

        NotificationViewController *vc = [[NotificationViewController alloc] initWithNibName:@"NotificationViewController" bundle:nil];
        vc.tableData = tableDataFromFile;

        UIViewController *root = self.mainNavController.topViewController;
        NSArray *vcs = [NSArray arrayWithObjects:root, vc, nil];
        [self.mainNavController setViewControllers:vcs animated:YES];
    }
        // app was already in the foreground
    else
    {
        while (done == FALSE)
        {

        }

        NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];

        NSString *alertMsg = @"";
        NSString *badge = @"";
        NSString *sound = @"";
        NSString *custom = @"";

        if( [apsInfo objectForKey:@"alert"] != NULL)
        {
            alertMsg = [apsInfo objectForKey:@"alert"];
        }


        if( [apsInfo objectForKey:@"badge"] != NULL)
        {
            badge = [apsInfo objectForKey:@"badge"];
        }


        if( [apsInfo objectForKey:@"sound"] != NULL)
        {
            sound = [apsInfo objectForKey:@"sound"];
        }

        if( [userInfo objectForKey:@"Type"] != NULL)
        {
            custom = [userInfo objectForKey:@"Type"];
        }

        // Set your appending text.
        NSString *textToAdd = [NSString stringWithFormat:@":%@", alertMsg];

        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSString *fileName = [NSString stringWithFormat:@"%@/AccountNotifications.txt", documentsDirectory];
        NSString *fileContents = [[NSString alloc]  initWithContentsOfFile:fileName usedEncoding:nil error:nil];

        NSString *textToFile;

        if (fileContents == NULL)
        {
            textToFile = alertMsg;
        }

        // Here you append new text to the existing one
        if (fileContents != NULL)
        {
            textToFile = [fileContents stringByAppendingString:textToAdd];
        }

        // Here you save the updated text to that file
        paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        documentsDirectory = [paths objectAtIndex:0];
        fileName = [NSString stringWithFormat:@"%@/AccountNotifications.txt", documentsDirectory];
        NSString *content = textToFile;
        [content writeToFile:fileName atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];

        NSArray *fileData = [textToFile componentsSeparatedByString:@":"];

        NSMutableArray *tableDataFromFile;
        tableDataFromFile = [[NSMutableArray alloc] init];

        int i = 0;

        for (i = 1; i < [fileData count]; i++)
        {
            [tableDataFromFile addObject:fileData[i]];
        }

        NotificationViewController *vc = [[NotificationViewController alloc] initWithNibName:@"NotificationViewController" bundle:nil];
        vc.tableData = tableDataFromFile;

        UIViewController *root = self.mainNavController.topViewController;
        NSArray *vcs = [NSArray arrayWithObjects:root, vc, nil];
        [self.mainNavController setViewControllers:vcs animated:YES];

    }
            // app was just brought from background to foreground


}

可能有人请帮我解决这个问题呢？ 一旦didFinishLaunchingWithOptions完成完成的布尔值被设置为true。 我只想notificationviewcontroller打开，如果同时应用程序不运行在所有被按下的通知显示通知。

Answer 1:

您应该添加一些像这样的代码：

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

        NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];

        //Accept push notification when app is not open
        if (remoteNotif) {      
            [self handleRemoteNotification:application userInfo:remoteNotif];
            return YES;
        }

        return YES;
    }

您可以从移动逻辑didReceiveRemoteNotification一些常见功能，并调用该函数，从两个地方。 这如果用户通过轻敲通知打开应用程序才有效。 如果用户通过点击应用程序图标打开应用，通知数据将不会到达应用程序。

Answer 2:

SWIFT代码

let remoteNotif: AnyObject? = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey]

            //Accept push notification when app is not open
            if ((remoteNotif) != nil) {

                self.handleRemoteNotification(remoteNotif!)
            }


func handleRemoteNotification(remoteNotif: AnyObject?){
//handle your notification here
}

@Eran谢谢:)
