試圖從ViewController與贊助商的UITableView Segoveue到另一個ViewController

Question

我仍然是新的iOS編程，我試圖實現一個應用程序，顯示信息爲學生參加週末長長的黑客馬拉松。我目前正在製作一張填有贊助商名單的表格，當您點擊一個贊助商Disclosure Button時，我希望它能夠延伸到另一個頁面，該頁面只顯示贊助商名稱和包含他們網站的網頁視圖。

我以爲我正確地設置了我的prepareForSegue方法，但是當我嘗試在iOS模擬器中進行選擇時沒有任何反應。有人可以看看我的代碼，並告訴我，如果我錯過了什麼嗎？

Answer 1

你應該實現

- （空）的tableView：（UITableView的*）的tableView accessoryButtonTappedForRowWithIndexPath：（NSIndexPath *）indexPath

的東西，如

-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath 
{ 
    [self performSegueWithIdentifier:@"sponsorSegue" sender:[self.allSponsors objectAtIndexPath: indexPath]]; 
} 

然後改變你SEGUE準備 sponsorDetailController.spon = sender;

Answer 2

我看到你已經在故事板從masterViewController到DetailViewController定義推SEGUE。

要執行SEGUE，你將需要實現的UITableView委託方法，特別是tableView:didSelectRowAtIndexPath:

PrepareForSegue是塞格斯的準備，它不執行塞格斯。

但是，當您點擊詳細披露按鈕，它沒有發生，但是當你點擊單元格，如果你按照這個執行。
