for 루프로 NSMutableArray 채우기

for 루프를 사용하여 숫자 1 - 10의 numbers라는 배열을 채우려고합니다. 그러나, 내가 알지 못하는 어떤 이유로 모든 것이 충돌합니다. 모든 충돌, 내가 무엇을하고 있어요 왜for 루프로 NSMutableArray 채우기

cell.textLabel.text = [numbers objectAtIndex:indexPath.row];

나도 몰라 :

for (int counter = 0; counter < 10; counter++) { 

    if (!numbers) 
    { 

     self.numbers = [[NSMutableArray alloc]init]; 

    } 

    [numbers addObject: [NSNumber numberWithInt:counter]]; 

} 

NSLog(@"%lu", [numbers count]);

그리고 테이블 셀에 숫자를 넣어 : 여기

내가 무엇을 시도했다입니다 나에게 맞는 것 같다.

또한 NSLog (@ "% i", [numbers count])가있는 이유를 알 수 없으므로 Xcode에서 경고를 '% lu'로 변경합니다. – Nathaly

어디에서 충돌 했습니까? 'numbers'와'self.numbers'는 같은 객체를 참조합니까? – KudoCC

@KudoCC, 나는 오류를 추가했다. 그리고 그렇습니다. – Nathaly

당신은 사용해야

cell.textLabel.text = [[numbers objectAtIndex:indexPath.row] stringValue];

누군가가 downvotes 할 때, 왜 그런지를 설명하는 글을 올리십시오. –

UILabel의의 텍스트 속성은 문자열을 원하지만, 당신은 그것에게의 NSNumber를 제공하고 있습니다 :

이 오류를 받고 있어요. 숫자의 문자열 값을 가져 가고 싶습니다.

사용이 : cell.textLabel.text = [NSString stringWithFormat:@"%@", [numbers objectAtIndex:indexPath.row]] ;

내가 주석 경우 또한 "말을 [숫자 addObject이 : [의 NSNumber numberWithInt가 : 카운터]] ;,가 충돌하지 않습니다 ... " 왜냐하면 주석 처리하면 숫자가 0이므로 셀이 필요하지 않기 때문입니다.
