第一种方法:clock2是使用 UILocalNotification,详见http://www.devdiv.com/thread-69786-1-1.html
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。
第二种方法:
multitask_demo.zip是前两天看见http://www.devdiv.com/article-1675-1.html
两种方法都可以实现,供大家学习。
