NSTableView 오류 - [__ NSCFConstantString setFrame :]

모두입니다. NSTableView를 사용하면이 함수에 도달하는 한 다음 오류가 발생합니다.NSTableView 오류 - [__ NSCFConstantString setFrame :]

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

USBInfor* usbInfor = [_tableContent objectAtIndex:row]; 
NSString* identifier = [tableColumn identifier]; 

return [usbInfor valueForKey:identifier]; 
}

USB의 이름, 크기, 경로 및 유형을 저장하기 위해 usbInfor 클래스를 만들었습니다. 그리고 이러한 변수를 _tableContent NSMutableArray에 추가합니다.

USBInfor *usbinfor = [[USBInfor alloc]init]; 
usbinfor.name = [mountPath substringFromIndex:9]; 
usbinfor.path = mountPath; 
usbinfor.size = formattingSize; 
usbinfor.type = type; 

[_tableContent addObject:usbinfor];

난 XIB 파일 3 열을 생성하고, 식별자 각각은 I 이름, 경로 및 크기 변수의 이름과 동일한 이름.

는 여기에 오류가 있습니다 :

그것은 OS X 10.5 및 기본 SDK의 OS X 10.7

"OS X 10.5에서 실행해야합니다."그런 다음보기 기반 테이블보기를 사용하면 안됩니다. 그것들은 라이온 (10.7)에서 소개되었습니다. Leopard (10.5) 또는 Snow Leopard (10.6)에서는 작동하지 않습니다. –

메서드, tableView : viewForTableColumn : row :는 NSView 또는 NSView의 하위 클래스를 반환해야합니다. [usbInfor valueForKey : identifier]는 identifier가 "name"인 문자열 ([mountPath substringFromIndex : 9])을 반환합니다. 네가 뭘하려고하는지 모르지만 분명히 틀렸어.

감사합니다 !!! :) :) :) –

[tableColumn identifier]는 열 이름을 식별하는 데 사용됩니다. 따라서 다음과 같아야합니다.

NSString *filename = [[itemArray1 objectAtIndex:rowIndex] objectForKey:key1a]; 
NSString *path = [[itemArray1 objectAtIndex:rowIndex] objectForKey:key1b]; 

NSString *identifier = [tableColumn identifier]; 
if ([identifier] isEqualToString:@"whatever a column name is"]) { 
    return filename; 
} 

else if ([identifier] isEqualToString:@"whatever a column name is"]) { 
    return path; 
}
