iphone 定时提醒

//定时提醒

-(void)schedulNotificationWithYear:(int)y andMonth:(int)m andDay:(int)d andHour:(int)h andMintu:(int)mi andMsg:(NSString *)msg{

    

    // Set up the fire time

    NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];

    NSDateComponents *dateComps = [[NSDateComponents alloc] init];

    [dateComps setDay:d];

    [dateComps setMonth:m];

    [dateComps setYear:y];

    [dateComps setHour:h];

// Notification will fire in one minute

    [dateComps setMinute:mi];

[dateComps setSecond:0];

    NSDate *itemDate = [calendar dateFromComponents:dateComps];

    [dateComps release];

    

    UILocalNotification *localNotif = [[UILocalNotification alloc] init];

    if (localNotif == nil)

        return;

    localNotif.fireDate = itemDate;

    localNotif.timeZone = [NSTimeZone defaultTimeZone];

    

// Notification details

    localNotif.alertBody = msg;

// Set the action button

    localNotif.alertAction = @"查看";

    

    localNotif.soundName = UILocalNotificationDefaultSoundName;

    //    localNotif.applicationIconBadgeNumber = 1;

    

// Specify custom data for the notification

    NSDictionary *infoDict = [NSDictionary dictionaryWithObject:@"someValue" forKey:@"someKey"];

    localNotif.userInfo = infoDict;

    

// Schedule the notification

    [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];

    [localNotif release];

}



在AppDelegate.m中添加如下代码，相当于回调函数





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



    UITextView *tv = (UITextView *)[[application keyWindow] viewWithTag:11];

    NSString *status = [NSString stringWithFormat:@"%@", [notif description]];

    tv.text = status;

    //添加处理代码

}
