本地通知“didReceiveLocalNotification”打电话两次

发布于 2024-09-09 05:13:09 字数 1278 浏览 8 评论 0原文

我正在使用以下方法处理本地通知：

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif

并安排本地通知：

- (void)scheduleNotificationWithInterval:(int)minutesBefore {
    UILocalNotification *localNotif = [[UILocalNotification alloc] init];

    if (localNotif == nil)
        return;

    NSDate *fireDate = [NSDate date];
    localNotif.fireDate = [fireDate dateByAddingTimeInterval:minutesBefore*60];
    localNotif.timeZone = [NSTimeZone defaultTimeZone];
    localNotif.repeatInterval = kCFCalendarUnitMinute;
    localNotif.alertBody = [NSString stringWithFormat:NSLocalizedString(@"LocalEvent notification in %i minutes.", nil),minutesBefore];
    localNotif.alertAction = NSLocalizedString(@"View Details", nil);
    localNotif.applicationIconBadgeNumber = 1;

    NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:@"This is dict, you can pass info for your notification",@"info",nil];
    localNotif.userInfo = infoDict;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

    [localNotif release];
    NSLog(@"Event scheduled");
}

当我收到通知时，didReceiveLocalNotification：被调用两次。

我做错了什么吗？

请帮忙。

谢谢。

I am handling local notifications using:

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif

And to schedule a local notification:

- (void)scheduleNotificationWithInterval:(int)minutesBefore {
    UILocalNotification *localNotif = [[UILocalNotification alloc] init];

    if (localNotif == nil)
        return;

    NSDate *fireDate = [NSDate date];
    localNotif.fireDate = [fireDate dateByAddingTimeInterval:minutesBefore*60];
    localNotif.timeZone = [NSTimeZone defaultTimeZone];
    localNotif.repeatInterval = kCFCalendarUnitMinute;
    localNotif.alertBody = [NSString stringWithFormat:NSLocalizedString(@"LocalEvent notification in %i minutes.", nil),minutesBefore];
    localNotif.alertAction = NSLocalizedString(@"View Details", nil);
    localNotif.applicationIconBadgeNumber = 1;

    NSDictionary *infoDict = [NSDictionary dictionaryWithObjectsAndKeys:@"This is dict, you can pass info for your notification",@"info",nil];
    localNotif.userInfo = infoDict;

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

    [localNotif release];
    NSLog(@"Event scheduled");
}

When I receive a notification, didReceiveLocalNotification: is called twice.

Am I doing something wrong?

Please help.

Thanks.

我认为模拟器中有一个已知的错误，它会触发委托通知方法两次。它不应该发生在设备上，无论是否与 XCode 绑定。

我也面临同样的问题，我找到的解决方案是在 didReceiveLocalNotification 中编写此代码，

if (state == UIApplicationStateActive) {
    NSLog(@"UIApplicationStateActive"); 
}
else if(state == UIApplicationStateInactive){
    NSLog(@"UIApplicationStateInActive");
}

在这些情况下，我只需编写我希望我的应用程序在活动模式下在通知上执行的代码，并且处于非活动模式

i was also facing the same problem and the solution which i find is that write this code in didReceiveLocalNotification

if (state == UIApplicationStateActive) {
    NSLog(@"UIApplicationStateActive"); 
}
else if(state == UIApplicationStateInactive){
    NSLog(@"UIApplicationStateInActive");
}

here in these condition i just write the code which i want my application to do on notification , in Active mode and in inactive mode

我怀疑只要在同一秒内通知就会被重新触发。我通过在处理程序中将 fireDate 设置为 nil 来修复它：

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
    UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:notification.alertAction message:notification.alertBody delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alertView show];

    notification.fireDate = nil;

}

I suspect that the notification is being retriggered as long as its in the same second still. I fixed it by setting the fireDate to nil in the handler:

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
    UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:notification.alertAction message:notification.alertBody delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alertView show];

    notification.fireDate = nil;

}

我也有同样的问题。这是由于在 AppDelegate 的“didFinishLaunchingWithOptions”中调用“registerUserNotificationSettings”两次引起的。然而，仅仅删除重复的调用并不能解决问题。我必须删除该应用程序然后重建。直到那时，双重本地通知问题才得到解决。
