在前台弹出通知

Question

我想在应用处于前台状态时显示通知弹出窗口，其中alertbody按照代码片段显示。
当应用程序处于后台状态时，它完全正常工作。在应用程序委托

UILocalNotification *notification = [[UILocalNotification alloc] init]; 
if (notification == nil) 
    return; 
NSDate *dt = [NSDate dateWithTimeInterval:10 sinceDate:[NSDate date]]; 
notification.fireDate = dt; 
notification.timeZone = [NSTimeZone defaultTimeZone]; 

notification.alertBody = @"After 10Secs..."; 
notification.alertAction = @"View"; 
[[UIApplication sharedApplication] scheduleLocalNotification:notification]; 

Answer 1

application:didreceiveLocalNotification方法，如果你想看到的nofication，而你的应用程序是在前台：

- (void)application:(UIApplication *)application 
    didReceiveLocalNotification:(UILocalNotification *)notification 
{ 
    //simply show a alert,but the standard one will not show up by itself 
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"MyAlertView" 
     message:notification.alertBody 
     delegate:self cancelButtonTitle:@"OK" 
     otherButtonTitles:nil]; 
    [alertView show]; 
    if (alertView) { 
     [alertView release]; 
    } 
}
