-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *CellID = @"CellID";
    PayWayCell *cell = [tableView dequeueReusableCellWithIdentifier:CellID];
    if (cell == nil) {
        cell = [[[NSBundle mainBundle]loadNibNamed:@"PayWayCell" owner:self options:nil]lastObject];

}

cell.selectionStyle = UITableViewCellSelectionStyleNone;

    cell.selectedBtn.selected = NO;
    [cell.selectedBtn setBackgroundImage:[UIImage imageNamed:@"person_recharge_selected@2X.png"] forState:UIControlStateSelected];
    cell.selectedBtn.enabled = YES;
    cell.selectedBtn.tag = 1000 + indexPath.row;
    [cell.selectedBtn addTarget:self action:@selector(selectedWay:) forControlEvents:UIControlEventTouchUpInside];


    return cell;
}
- (void)selectedWay:(UIButton *)btn{
    btn.selected = !btn.selected;
    way = btn.tag - 1000;
    UIButton *btn0 = (UIButton *)[self.view viewWithTag:1000];
    UIButton *btn1 = (UIButton *)[self.view viewWithTag:1001];
    UIButton *btn2 = (UIButton *)[self.view viewWithTag:1002];

    if (btn.selected) {
        if (btn.tag == 1000) {
            btn0.selected = YES;
            btn1.selected = NO;
            btn2.selected = NO;
        }else if (btn.tag == 1001) {
            btn1.selected = YES;
            btn0.selected = NO;
            btn2.selected = NO;
        }else if (btn.tag == 1002) {
            btn2.selected = YES;
            btn0.selected = NO;
            btn1.selected = NO;

    }
