我如何重新加載我的UIViewController？

Question

我有一個代碼在viewDidLoad和其他方法，我想重新加載它們，如果我點擊一個按鈕，我已經嘗試setNeedDisplay但它不工作，我不知道如果我在右邊使用它SENS？

在viewDidLoad中這是我的代碼：

 - (void)viewDidLoad 
    { 
     // Create the UISegmentedControler "Next Review" and "Previouse Review" 
     UISegmentedControl *paginateReviewSegment = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Précedent",@"Suivant", nil]]; 
     paginateReviewSegment.segmentedControlStyle = UISegmentedControlStyleBar; 
     [paginateReviewSegment addTarget:self action:@selector(paginateReviews:) forControlEvents:UIControlEventValueChanged]; 

     UIBarButtonItem *paginateBarButton = [[UIBarButtonItem alloc] initWithCustomView:paginateReviewSegment]; 
     self.navigationItem.rightBarButtonItem = paginateBarButton; 

     [super viewDidLoad]; 

    // Get the review selected 
     entryReview = [[entriesReview getEntries] objectAtIndex:self.reviewSelected]; 

    // Resize the UIScrollView 
    [self.scrollView setScrollEnabled:YES]; 
    [self.scrollView setContentSize:self.contentView.frame.size]; 

    // Add UIView "Content" to UIScrollView 
    [self.scrollView addSubview:self.contentView]; 

    // Set the user name 
    userNameLabel.text = entryReview.userName; 

    ..... 
    } 

這是我要使用重新加載的UIView動作：

- (void)paginateReviews:(UISegmentedControl*)sender 
    { 
     if (sender.selectedSegmentIndex == 0 && self.reviewSelected != 0) 
     { 
      self.reviewSelected -= 1; 
      entryReview = [[entriesReview getEntries] objectAtIndex:self.reviewSelected]; 
      [self.view setNeedsDisplay]; 

     } else if(sender.selectedSegmentIndex == 0 && self.reviewSelected != ([entriesReview entriesCount] - 1)) 
     { 
      self.reviewSelected += 1; 
      entryReview = [[entriesReview getEntries] objectAtIndex:self.reviewSelected]; 
     } 

    }

[self.view setNeedsDisplay];不會調用[self viewDidLoad];。

而且，我們不手動撥打viewDidLoad。我建議將你想調用的代碼移動到另一個方法中，並在viewDidLoad和用你的按鈕綁定方法中調用該方法。
