关于UITableViewCell单选

废话不说， 直接上代码。。。。。
@interface CJWPopCardListView ()<UITableViewDelegate, UITableViewDataSource>
@property (nonatomic, assign) NSIndexPath *selectedIndexPath;//定义选中的cell 的indexPath
@end
@implementation CJWPopCardListView

//cell复用里面

• (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
  CJWCardTableViewCell *cell = (CJWCardTableViewCell *)[tableView dequeueReusableCellWithIdentifier:@"CJWCardTableViewCell" forIndexPath:indexPath];
  cell.selectionStyle = UITableViewCellSelectionStyleNone;
  if (indexPath.row == _bankListArray.count) {
  cell.cardInfoLabel.text = @"使用其它银行卡";
  cell.arrowImg.hidden = NO;
  }else{
  if (_bankListArray.count) {
  cell.cardInfoLabel.text = [NSString stringWithFormat:@"%@",emptyString([[_bankListArray objectAtIndex:indexPath.row]objectForKey:@"bank_name"])];
  }
  cell.arrowImg.hidden = YES;
  }
  //重点在此
  if ([self.selectedIndexPath isEqual:indexPath]){

    cell.accessoryType = UITableViewCellAccessoryCheckmark;
  

  }else{

    cell.accessoryType = UITableViewCellAccessoryNone;
  

  }
  return cell;
  }

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

  if (indexPath.row == _bankListArray.count) {
  NSLog(@"添加银行卡");
  [self closeView];
  }else{

    if (self.selectedIndexPath) {
        
        CJWCardTableViewCell *cell = [tableView cellForRowAtIndexPath:self.selectedIndexPath];
        
        cell.accessoryType = UITableViewCellAccessoryNone;
        
    }
    
    CJWCardTableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
    
    self.selectedIndexPath = indexPath;
    NSDictionary *selDic = [_bankListArray objectAtIndex:indexPath.row];
    NSLog(@"选中的银行卡信息：%@",selDic);
    if (_delegate && [_delegate respondsToSelector:@selector(selectedBankInfoDic:)]) {
        [_delegate selectedBankInfoDic:selDic];
    }
  }
  

}
