【源码下载】在实现了一系列的扩展功能后的Your Second iOS App的源码下载

急盼回复,我也是根据官网的文章来实现second ios app,遇到一个问题,在master 的处理addview 的done:segue方法里面,提示错误,../BirdWatching/BirdsMasterViewController.m:136:21: Property 'birdSighting' not found on object of type 'AddSightingViewController *'.该方法代码如下: - (IBAction)done:(UIStoryboardSegue *)segue{ if ([[segue identifier] isEqualToString:@"ReturnInput"]) { AddSightingViewController *addController = [segue sourceViewController]; if (addController.birdSighting) { [self.dataController addBirdSightingWithSighting:addController.birdSighting]; [[self tableView] reloadData]; } [self dismissViewControllerAnimated:YES completion:NULL]; } } AddSightingViewController.h代码如下: #import @class BirdSighting; @interface AddSightingViewController : UITableViewController @property (strong, nonatomic) BirdSighting *birdSighting; @property (weak, nonatomic) IBOutlet UITextField *birdNameInput; @property (weak, nonatomic) IBOutlet UITextField *locationINput; @end AddSightingViewController.m代码如下: #import "AddSightingViewController.h" #import "BirdSighting.h" @interface AddSightingViewController () @end @implementation AddSightingViewController - (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{ if ([[segue identifier] isEqualToString:@"ReturnInput"]) { if ([self.birdNameInput.text length] || [self.locationINput.text length]) { BirdSighting *sighting; NSDate *today = [NSDate date]; sighting = [[BirdSighting alloc] initWithName:self.birdNameInput.text location:self.locationINput.text date:today]; self.birdSighting = sighting; } } } 看提示错误,好像是找不到birdSighting这个property,可事实上我在AddSightingViewController.h定义了.
