Ios 前台弹出通知

我想在应用程序处于前台状态时显示通知弹出窗口，根据代码片段显示alertbody
当应用程序处于后台状态时，它完全可以工作

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];

application:didreceiveLocalNotification

方法，如果您希望在应用程序处于前台时查看编号：

- (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];
    }
}

我假设您知道，当应用程序处于前台状态时，会在ApplicationIDReceiveLocalNotification方法中收到通知（但不确定方法的名称），如果您希望显示类似于横幅的通知，可以从中显示警报。
