ios - 输入 applicationDidBecomeActive 时本地通知不起作用

Question

我正在使用重复本地通知向用户显示警报。为此，我使用了下面的代码

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [[NSDate date] dateByAddingTimeInterval:60];
localNotification.alertBody = @"sss";
localNotification.alertAction = @"Show me the item";
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

使用 NSNotification Center，我将每 60 秒调用一次本地通知。它工作正常。

同样在 Appdelegate 中，我使用以下代码:-

 - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
    {
        NSLog(@"Received");
        UIApplicationState state = [application applicationState];
        if (state == UIApplicationStateActive) {

             [[NSNotificationCenter defaultCenter] postNotificationName:@"RestartProcess" object:self];

}
 application.applicationIconBadgeNumber = 0;
}

还有

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    UILocalNotification *locationNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (locationNotification) {
        // Set icon badge number to zero
        NSLog(@"Yes Notid=fications is predsent");
        application.applicationIconBadgeNumber = 0;
    }

    return YES;
}

我的问题是当本地通知开始时，我按下主页按钮然后等待显示。时间段后显示通知消息。当我点击应用程序图标时，进程停止。之后本地通知不起作用。但是当我点击通知消息时它会正常工作。我如何解决这个问题。任何人都可以帮助我做到这一点。提前致谢..

didReceiveLocalNotification 仅在您点击通知消息时调用。如果您想在 applicationDidBecomeActive 中执行此操作，则必须手动执行。

您可以检查角标(Badge)数量(如果通知包含角标(Badge))，例如:

-(void) applicationDidBecomeActive:(UIApplication *)application
{

    if(application.applicationIconBadgeNumber >= 1)
    {
       //Do you stuff here
        application.applicationIconBadgeNumber = 0;

    }
}
