APPDelegate需要實(shí)現(xiàn)的代碼為:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
// 如果應(yīng)用程序在前臺(tái)舰褪，將應(yīng)用程序圖標(biāo)上紅色徽標(biāo)中數(shù)字設(shè)為0
application.applicationIconBadgeNumber = 0;
// 使用UIAlertView顯示本地通知的信息
[[[UIAlertView alloc] initWithTitle:@"收到通知"
message:notification.alertBody
delegate:nil cancelButtonTitle:@"確定" otherButtonTitles:nil] show];
}

編輯一個(gè)UIApplication *app;對(duì)象 并且初始化
app = [UIApplication sharedApplication];
設(shè)置一個(gè)按鈕實(shí)現(xiàn)以下代碼
- (IBAction)KaiGuan:(id)sender

//創(chuàng)建一個(gè)本地通知
UILocalNotification * notification = [[UILocalNotification alloc]init];
