当前类别是字符串而不是数组这里是它的正确代码

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

{

[tableView deselectRowAtIndexPath:indexPath animated:NO];

NSInteger genderIndex = [genderList indexOfObject:self.selectedGender];

if (genderIndex == indexPath.row) {
    return;
}

NSIndexPath *oldIndexPath = [NSIndexPath indexPathForRow:genderIndex inSection:0];

UITableViewCell *newCell = [tableView cellForRowAtIndexPath:indexPath];
if (newCell.accessoryType == UITableViewCellAccessoryNone) {
    newCell.accessoryType = UITableViewCellAccessoryCheckmark;
    self.selectedGender = [genderList objectAtIndex:indexPath.row];
}

UITableViewCell *oldCell = [tableView cellForRowAtIndexPath:oldIndexPath];
if (oldCell.accessoryType == UITableViewCellAccessoryCheckmark) {
    oldCell.accessoryType = UITableViewCellAccessoryNone;
}

NSLog(@"the selected cell is %@",selectedGender);

}
