Answer 1

在您的情况下，您需要设置fireDate它是您的通知到达的日期/时间，并设置repeatInterval它描述您的通知重复。在这里，您需要设置kCFCalendarUnitDay，因为您想每天重复通知。

REPEAT UNIT：

NSEraCalendarUnit
  NSYearCalendarUnit
  NSMonthCalendarUnit
  NSDayCalendarUnit
  NSHourCalendarUnit
  NSMinuteCalendarUnit
  NSSecondCalendarUnit
  NSWeekCalendarUnit
  NSWeekdayCalendarUnit
  NSWeekdayOrdinalCalendarUnit
  NSQuarterCalendarUnit

在AppDelegate.m中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  [launchOptions valueForKey:UIApplicationLaunchOptionsLocalNotificationKey];
  return YES;
 }

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification 
{    
  UIAlertView *notificationAlert = [[UIAlertView alloc] initWithTitle:@"Notification"    message:@"This local notification" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
  [notificationAlert show];
   // NSLog(@"didReceiveLocalNotification");
}

将此代码放在ViewController的.m文件中：

-(IBAction)startLocalNotification 
{  
  NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
  [dateFormatter setDateFormat:@"h:mm a"];
  NSDate *dateFromString = [[NSDate alloc] init];
  dateFromString = [dateFormatter dateFromString:timeStr];

  NSLog(@"startLocalNotification");    
  UILocalNotification *notification = [[UILocalNotification alloc] init];
  notification.fireDate = dateFromString;
  notification.repeatInterval = NSDayCalendarUnit;
  notification.alertBody = @"This is local notification!";
  notification.timeZone = [NSTimeZone defaultTimeZone];
  notification.soundName = UILocalNotificationDefaultSoundName;
  notification.applicationIconBadgeNumber = 10;
  [[UIApplication sharedApplication] scheduleLocalNotification:notification];    
}
