使用第三方《UITableView+FDTemplateLayoutCell》自动计算UITableViewCell高度（Masonry约束）

直接上代码：

1：先自定义cell

.h文件中

@property (nonatomic, strong) UIView *bgView;

@property (nonatomic, strong) UIView *topLineView;

@property (nonatomic, strong) UILabel *orderNum;

@property (nonatomic, strong) UIView *lineView;

    }];

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

{

    return _msgArr.count;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

    [self setupModelOfCell:cell atIndexPath:indexPath];

    return cell;

}

- (void)setupModelOfCell:(LBDMsgCenterCell *) cell atIndexPath:(NSIndexPath *) indexPath {

    // 采用计算frame模式还是自动布局模式，默认为NO，自动布局模式

    //    cell.fd_enforceFrameLayout = NO;
