定時提醒實現

UILocalNotification *notification=[[UILocalNotification alloc] init];
        if (notification!=nil)
        {
           
            NSDate *now=[NSDate new];
          
            //notification.fireDate=[now addTimeInterval:period];
            notification.fireDate = [now dateByAddingTimeInterval:period];
            NSLog(@"%d",period);
            notification.timeZone=[NSTimeZone defaultTimeZone];
            notification.soundName = @"ping.caf";
            //notification.alertBody=@"TIME!";
           
            notification.alertBody = [NSString stringWithFormat:@"@%時間到了!",nameStr];
           
            NSDictionary* info = [NSDictionary dictionaryWithObject:uniqueCodeStr forKey:CODE];
            notification.userInfo = info;
           
            [[UIApplication sharedApplication] scheduleLocalNotification:notification];     
           
        }

設置的時間到了之後,會自動在桌面彈出一個提示框,點顯示後,就能夠啓動軟件。而後在
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (localNotif)
    {
        NSLog(@"Recieved Notification %@",localNotif);
        NSDictionary* infoDic = localNotif.userInfo;
        NSLog(@"userInfo description=%@",[infoDic description]);
        NSString* codeStr = [infoDic objectForKey:CODE];
    }
}裏,對lanchOptions進行處理,找到它裏面的信息,就能夠拿到設置時的須要處理的東西,就能夠繼續操做了。

若是此時你的客戶端 軟件仍在打開,則會調用
- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif
{

}
同樣的處理方法。app
