如何將值NSLabel從一個表示形式傳遞給另一個表示形式。與故事板

Question

如何將值從一個控制器傳遞給另一個？我使用StoryBoard。

-(void) prepareForSegue:(UIStoryboardPopoverSegue *)segue sender:(id)sender 
{ 
    if ([segue.identifier hasPrefix:@"FinishController"]) { 
     FinishController *asker = (FinishController *) segue.destinationViewController; 
     asker.FinishDesc = @"What do you want your label to say?"; 
     asker.FinishTitle = @"Label text"; 
     asker.FinishPoint = @"asdas"; 
    } 
} 

我想出現在第一個視圖中突出顯示的文本視圖。我想這樣的東西應該看起來像這樣： UIStoryboard * finish = [UIStoryboard storyboardWithName：@「MainStoryboard」bundle：nil];

 UIViewController *viewController = [finish instantiateViewControllerWithIdentifier:@"FinishController"]; 

    viewController.modalPresentationStyle = UIModalPresentationPageSheet; 
    [self presentModalViewController:viewController animated:YES]; 

finishcontroller：

- (void)viewDidLoad 
{ 
    self.lblFinishTitle.text=self.FinishTitle; 
    self.lblFinishDesc.text = self.FinishDesc; 
    self.lblFinishPoint.text=self.FinishPoint; 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 
}

是使用全局變量的可能嗎？如果是這樣，看看一些叫做「extern」的東西。希望這給你一個方向=]
