CityView.m

NSString *selectedCity =@"上海";

[[NSNotificationCenter defaultCenter]postNotificationName:@"ChangeCurrentCityName" object:selectedCity];

 

GoodViewController.m

  [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(receiveNotification:) name:@"ChangeCurrentCityName" object:nil];

   

-(void)receiveNotification:(NSNotification*)noti

{

　　UILabel *cityNameLabel=[[UILabel alloc]initWithFrame:CGRectMake(0,0,100,100)];

    //NSLog(@"%@",noti.object);

    cityNameLabel.text=noti.object;

}
