iOS闹钟实现

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:@"@%时间到了!",nameStr];

NSDictionary* info = [NSDictionary dictionaryWithObject:uniqueCodeStr forKey:CODE];

notification.userInfo = info;

[[UIApplication sharedApplication] scheduleLocalNotification:notification];

}

设置的时间到了以后，会自动在桌面弹出一个提示框，点显示后，就可以启动软件。然后在

- (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];

}

}里，对lanchOptions进行处理，找到它里面的信息,就可以拿到设置时的需要处理的东西，就可以继续操作了。

如果此时你的客户端 软件仍在打开，则会调用

- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif

{

}

一样的处理方法。
