xcode로 컴파일 할 때 cellForRowAtIndexPath가 호출되지 않습니다. 6.1

Question

내 앱에서 [테이블보기] [1] (으)로 팝업됩니다.

Xcode 5.1로 컴파일하면 모든 것이 정상적으로 작동하지만 Xcode 6.1로 컴파일 된 동일한 코드는 [cellForRowAtIndexPath] [012]을 호출하지 못했습니다.

다른 대리자가 호출됩니다.

한 intersting 점은 self.tableView.rowHeight; -1을 반환 내가 자기에게 위임 및 데이터 소스를 설정 명시 적으로 시도

입니다하지만 클래스는 다음 코드에 의해 호출된다

하지 차이를 만든다;

`-(IBAction)selectLanguage:(id)sender 
{ 
    ATLMLanguagePopoverTableViewController *pvc = [[ATLMLanguagePopoverTableViewController alloc] initWithNibName:nil bundle:nil]; 
    pvc.target = self; 
    pvc.action = @selector(popoverDidSelectItem:); 
    pvc.items = [[[ATLMLibraryManager getManager]libraryDefaults]getAvailableLanguageNames]; 
    _myPopoverController.contentViewController = pvc; 
    [_myPopoverController setPopoverContentSize:[pvc popoverContentSize]]; 
    [_myPopoverController presentPopoverFromBarButtonItem:(UIBarButtonItem *)sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES]; 
} 
`

듣고는 클래스 내 자신의 질문에 대답 OK

Answer 1

의 정의입니다;

기본적으로 코드는 init 메서드가 호출 된 후 모델을보기 컨트롤러에 추가합니다. 그러나 모델이 추가되기 전에 스레드 모델이 조금 변경되었고 뷰가 생성되어 모델의 행 수가 0이되는 것 같습니다.

해결 방법은 모델을 init 메소드의 일부로 전달하는 것입니다.

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil items:(NSArray *)itemArray 
{ 
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 
    if (self) { 
     // Custom initialization 
     items = [itemArray copy]; 
     selectedItem = -1; 
     target = nil; 
     action = nil; 
    } 
    return self; 
}
