iOS cell上按钮的展开闭合和单选

一、cell上按钮的展开闭合

1.声明个BOOL数组

    {
        BOOL isUnfolds[500];
    }

2.点击回调方法，对BOOL数组中当前index进行取反，刷新当前index的行

        cell.unfoldBtnClickBlock = ^(UIButton *unfoldBtn) {
            isUnfolds[indexPath.row] = !isUnfolds[indexPath.row];
    
            NSIndexPath *indexPath1 = [NSIndexPath indexPathForRow:indexPath.row inSection:0];
            NSLog(@"第几行%ld",indexPath.row);
            [self.seleTableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath1, nil] withRowAnimation:UITableViewRowAnimationAutomatic];
        };

3.cellForRowAtIndexPath方法中写入BOOL数组index判断方法，并进行 视图的remake

     // 展开、闭合
        cell.foldBtn.tag = indexPath.row;
        if (isUnfolds[indexPath.row]) {
            cell.foldBtn.selected = YES;
            
            [cell.topBGView remakeConstraints:^(MASConstraintMaker *make) {
                make.top.equalTo(cell.top).offset(10);
                make.left.equalTo(cell.left).offset(14);
                make.width.equalTo(SelfWidth-60);
                make.height.equalTo(90+90);
            }];
            cell.bottomBGView.hidden = NO;
    
        } else {
            cell.foldBtn.selected = NO;
    
            [cell.topBGView remakeConstraints:^(MASConstraintMaker *make) {
                make.top.equalTo(cell.top).offset(10);
                make.left.equalTo(cell.left).offset(14);
                make.width.equalTo(SelfWidth-60);
                make.height.equalTo(90);
            }];
            cell.bottomBGView.hidden = YES;
        }

二、cell上的按钮单选

    1. 声明属性

        @property (nonatomic , strong) NSIndexPath *lastIndexPath;

    2.cellForRowAtIndexPath 方法中实现代码

            NSInteger row = [indexPath row];
            NSInteger oldRow = [_lastIndexPath row];
            if (row == oldRow && _lastIndexPath) {
                cell.defaultLab.text = @"设为默认地址";
                cell.defaultLab.textColor = HEXCOLOR(0xff4e11);
                cell.gouImageView.image = [MSUPathTools showImageWithContentOfFileByName:@"WechatIMG169"];
            }

    3.didSelectRowAtIndexPath 方法中实现代码

            NSInteger newRow = [indexPath row];
            NSInteger oldRow = self.lastIndexPath?[self.lastIndexPath row]:-1;
            if (newRow != oldRow) {
                MSUManageAddressTableCell *NewCell = [tableView cellForRowAtIndexPath:indexPath];
                NewCell.defaultLab.text = @"设为默认地址";
                NewCell.defaultLab.textColor = HEXCOLOR(0xff4e11);
                NewCell.gouImageView.image = [MSUPathTools showImageWithContentOfFileByName:@"WechatIMG169"];
                
                MSUManageAddressTableCell *oldCell = [tableView cellForRowAtIndexPath:_lastIndexPath];
                oldCell.defaultLab.text = @"默认地址";
                oldCell.defaultLab.textColor = HEXCOLOR(0x333333);
                oldCell.gouImageView.image = [MSUPathTools showImageWithContentOfFileByName:@"WechatIMG217"];
                
                self.lastIndexPath = indexPath;
            }
