UItableViewCell 체크 표시 다시 설정

Question

다음 코드는 빈 셀로 시작하고 선택한 셀을 선택하면 체크 표시가 추가되지만 한 번 추가하면 해당 셀을 다시 누르면 지워지지 않습니다. didSelectRowAtIndexPath가 호출 될 때마다 다시 설정하려고합니다. 하나만 표시되도록 셀을 지우는 방법은 무엇입니까? 감사.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; 
     cell.accessoryType = UITableViewCellAccessoryNone; 

    if (indexPath.section == 0) { 

    switch (indexPath.row) { 
     case 0: 
      labelInfo.text=@"1"; 
      cell.accessoryType = UITableViewCellAccessoryCheckmark; 
      break; 
     case 1: 
      labelInfo.text=@"2"; 
      cell.accessoryType = UITableViewCellAccessoryCheckmark; 
      break; 
     case 2: 
      labelInfo.text=@"3"; 
      cell.accessoryType = UITableViewCellAccessoryCheckmark; 
      break; 
     case 3: 
      labelInfo.text=@"4"; 
      cell.accessoryType = UITableViewCellAccessoryCheckmark; 
      break; 
     case 4: 
      labelInfo.text=@"5"; 
      cell.accessoryType = UITableViewCellAccessoryCheckmark; 
      break; 
     default: 
      break; 
     } 
    } 
}

에 대한

if (cell.accessoryType == UITableViewCellAccessoryCheckmark) { 
    cell.accessoryType = UITableViewCellAccessoryNone; 
} else { 
    cell.accessoryType = UITableViewCellAccessoryCheckmark; 
} 

확인 표시 전환에 대한

및

labelInfo.text = [NSString stringWithFormat:@"%d", indexPath.row + 1]; 

같은 사용 뭔가 그냥이를 복사하여 붙여 넣습니다. 그것은 작동합니다.

//in your .h file 
    int selectedCell; 

    //in your .m file 
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
    { 

     NSString* cellIdentifier = @"cellIdentifier"; 
     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; 

     if(cell == nil) 
     { 
      cell = (UITableViewCell*) [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier]; 

     } 
     cell.accessoryType = UITableViewCellAccessoryNone; 

     if (indexPath.section == 0) { 

      if(indexPath.row == selectedCell) 
      { 
        cell.accessoryType = UITableViewCellAccessoryCheckmark; 
        cell.selected = YES; 
      } 
      else 
      { 
       cell.accessoryType = UITableViewCellAccessoryNone; 
       cell.selected = NO; 
      } 
     } 
    } 



    - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
    { 
     selectedCell = indexPath.row; 
     [tableView reloadData]; 
     //remaining code. 
    }

이 시도 : 코드에서

if (cell.accessoryType == UITableViewCellAccessoryCheckmark) { 
    cell.accessoryType = UITableViewCellAccessoryNone; 
} else { 
    cell.accessoryType = UITableViewCellAccessoryCheckmark; 
} 

Answer 3

당신이 선택한 셀에서 확인 표시를 제거

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; 
    cell.accessoryType = UITableViewCellAccessoryNone; 

로 시작하지만 나중에

switch (indexPath.row) { 
    case 0: 
     labelInfo.text=@"1"; 
     cell.accessoryType = UITableViewCellAccessoryCheckmark; 
     break; 
    case 1: 
     labelInfo.text=@"2"; 
     cell.accessoryType = UITableViewCellAccessoryCheckmark; 
     break; 
    case 2: 
     labelInfo.text=@"3"; 
     cell.accessoryType = UITableViewCellAccessoryCheckmark; 
     break; 
    case 3: 
     labelInfo.text=@"4"; 
     cell.accessoryType = UITableViewCellAccessoryCheckmark; 
     break; 
    case 4: 
     labelInfo.text=@"5"; 
     cell.accessoryType = UITableViewCellAccessoryCheckmark; 
     break; 
    default: 
     break; 
    } 

다시 체크 표시를 할당

그래서, 당신은 c 라벨

이 코드는 테이블

[[self.tableView visibleCells] makeObjectsPerformSelector:@selector(setAccessoryType:) withObject:UITableViewCellAccessoryNone];
