UILocalNotification中的警报未被调用

Question

AppDelegate.m

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

application.applicationIconBadgeNumber = 0;
}

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
application.applicationIconBadgeNumber = 0;
NSString *reminderText = [notification.userInfo objectForKey:kRemindMeNotificationDataKey];
[self.settings showReminderAlert:reminderText];
NSLog(@"Application REcieved Local Notification");
}

ViewController.m

-(void)showReminderAlert:(NSString *)text{
NSLog(@"Alert Called");
UIAlertView *reminderAlert = [[UIAlertView alloc]initWithTitle:@"Alert" message:text delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[reminderAlert show];
[reminderAlert release];
}

我希望我的应用程序在用户重新登录application.app didReceiveLocalNotification时显示警告但是调用了Alert方法。

您在另一个视图控制器中的showReminderAlert:对吗？可能是对象self.settings（该视图控制器的对象）在重新打开应用程序时获得释放。在appDelegate本身尝试提醒

 -(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Alarm" message:message delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
            [alert show];
            [alert release];
}
