iOS：如何將表視圖單元格的第一個視圖控制器標籤數據傳遞給第二個視圖控制器的textView？

Question

我正在開發一個應用程序，在該應用程序中，我想將第一個視圖控制器的表格視圖單元格標籤數據顯示在第二個視圖控制器的textView上，當單擊該按鈕時。我已經實現了代碼，但是當我點擊按鈕時，第二個視圖的textView變爲空白。請建議我在下面的代碼中犯了錯誤，我嘗試了很多次，但無法成功。

第一個視圖控制器：

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
    self.jobPostedTableView.dataSource = self; 

    //Slide Navigation 
    [self.sideNavigation addTarget:[SlideNavigationController sharedInstance] action:@selector(toggleLeftMenu) forControlEvents:UIControlEventTouchUpInside]; 

    WebManager *manager = [WebManager sharedInstance]; 
    [manager getJobPostedWithCompletionBlock:^(id response){ 
     NSDictionary *dictionary = (NSDictionary *)response; 

     // Read data from JSON 
     NSDictionary *responseObject = [dictionary objectForKey:@"response"]; 
     NSLog(@"The Array%@",responseObject); 

     self.bids = [responseObject objectForKey:@"bids"]; 
     self.job_description = [responseObject objectForKey:@"job_description"]; 
     self.job_id = [responseObject objectForKey:@"job_id"]; 
     self.job_completed = [responseObject objectForKey:@"job_completed"]; 
     self.job_latitude = [responseObject objectForKey:@"job_latitude"]; 
     self.job_longitude = [responseObject objectForKey:@"job_longitude"]; 
     self.job_priority = [responseObject objectForKey:@"job_priority"]; 
     self.job_start_date = [responseObject objectForKey:@"job_start_date"]; 
     self.job_title = [responseObject objectForKey:@"job_title"]; 

     [self.jobPostedTableView reloadData]; 
    }]; 

    self.reversedGeocodes = [NSMutableDictionary dictionary]; 

     } 

    #pragma mark - TableView Data Source 

    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
    { 
     return [self.job_title count]; 
    } 

    - (NSInteger) numberOfSectionsInTableview:(UITableView *)tableView 
    { 
     return 1; 
    } 

    - (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
    { 
     static NSString *cellIdentifier = @"JobTableViewCell"; 
     JobTableViewCell *cell = (JobTableViewCell *)[self.jobPostedTableView dequeueReusableCellWithIdentifier:cellIdentifier]; 

     if(cell == nil) { 

      cell = [[JobTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier]; 
     } 
     // Comparing array string to display an urgent image 
     if ([[self.job_priority objectAtIndex:indexPath.row] 
      isEqualToString:@"urgent"]) { 
      cell.urgentLabel.hidden = NO; 
     } else { 
       cell.urgentLabel.hidden = YES; 
     } 
     // Condition whether job completed is open or closed 
     if ([[self.job_completed objectAtIndex:indexPath.row] 
      isEqualToString:@"1"]) { 
      cell.jobStatus.text = @"Open"; 
      [cell.jobStatus setTextColor:[UIColor colorWithRed:(84/255.f) green:(56/255.f) blue:(255/255.f) alpha:1.0f]]; 
      cell.flagImage.image = [UIImage imageNamed:@"jobPosted_opened.PNG"]; 
     } else { 
      cell.jobStatus.text = @"Closed"; 
      [cell.jobStatus setTextColor:[UIColor colorWithRed:(179/255.f) green:(179/255.f) blue:(180/255.f) alpha:1.0f]]; 
      cell.flagImage.image = [UIImage imageNamed:@"jobPosted_closed.PNG"]; 
     } 

     cell.jobTitle.text = [self.job_title objectAtIndex:indexPath.row]; 
     cell.jobContent.text = [self.job_description objectAtIndex:indexPath.row]; 
     cell.bidsLabel.text = [[self.bids objectAtIndex:indexPath.row ]stringValue]; 
     // Latitude and Longitude 

     float lat = [self.job_latitude[indexPath.row] floatValue]; 
     float lng = [self.job_longitude[indexPath.row] floatValue]; 

     [self locationNameWithLat:lat 
           lng:lng 
       completionHandler:^(NSString *locationName, NSError *error) { 
        cell.locationJob.text = locationName; 
       }]; 


     return cell; 

    } 

- (IBAction)onClickJobButton:(id)sender { 

    JobDetailsViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"JobDetailsViewController"]; 
    [self.navigationController pushViewController:vc animated:YES]; 
    NSIndexPath *indexPath = [self.jobPostedTableView indexPathForSelectedRow]; 
    JobDetailsViewController *jobDetailsController = [[JobDetailsViewController alloc]init]; 
    jobDetailsController.jobDetailView = [self.job_description objectAtIndex:indexPath.row]; 
} 

第二個視圖控制器：

- (void)viewDidLoad { 
[super viewDidLoad]; 
// Do any additional setup after loading the view. 
WebManager *manager = [WebManager sharedInstance]; 
NSString *user_name = manager.completeName; 
self.nameLabel.text = user_name; 
self.jobtextView.text = self.jobDetailView; 

}

如果您使用的塞格斯，您可以使用prepareForSegue方法發送的文字：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
{ 

    // Make sure your segue name in storyboard is the same as this line 
    if ([[segue identifier] isEqualToString:@"YOUR_SEGUE_NAME_HERE"]) 
    { 
     // Get reference to the destination view controller 
     YourSecondViewController *vc = [segue destinationViewController]; 

     // Pass labelData which is a string 
     [vc setTextString:labelData]; 
    } 
} 

而且不要忘了申報字符串屬性在SecondViewController.h

@property(nonatomic,strong) NSString *textString;
