NSTableView는 objectValueForTableColumn 메서드의 반환 값을 표시하지 않습니다.

Question

반환하는 내용과 상관없이 테이블보기는 .xib 파일에서 수동으로 설정된 표시 텍스트 (NSTextField의 'Title') 만 표시합니다. 내가 뭘 잘못하고 있는지 알아내는 데 도움주세요. 감사.

내 NSTableView에는 1 개의 열만 있습니다.

가되어있는 tableview 콘텐츠 모드를 기반으로 셀 또는 뷰를 기반으로 : 여기

코드인가? 나는

- (NSView *)tableView:(NSTableView *)tableView 
    viewForTableColumn:(NSTableColumn *)tableColumn 
        row:(NSInteger)row { 

     // Retrieve to get the @"MyView" from the pool or, 
     // if no version is available in the pool, load the Interface Builder version 
     NSTableCellView *result = [tableView makeViewWithIdentifier:@"MyView" owner:self]; 

     // Set the stringValue of the cell's text field to the nameArray value at row 
     result.textField.stringValue = [self.nameArray objectAtIndex:row]; 

     // Return the result 
     return result; 
}
