IOS 用Masonry和FDTemplateLayoutCell实现uitableviewcell自动布局

UITableView+FDTemplateLayoutCell这个开源类,让cell高度的自适应变得格外容易!
具体的使用方法请戳该类作者博客:http://blog.sunnyxx.com/2015/05/17/cell-height-calculation/文章对tableViewCell高度计算的原理及此类的实现原理等解释得非常清晰,具体的使用方法和demo可直接参考文章内容.
这里只说几个需要注意的点:
1.使用该类的时候,cell要通过tableView的registerNib...或者registerClass...的方法进行注册(联想UICollectionViewCell的用法),如:

[tableView registerNib:[UINib nibWithNibName:@"ProdDetailCell" bundle:nil]forCellReuseIdentifier:@"ProdDetailCell"];

或者:

[tableView registerClass:[ProdDetailCell class] forCellReuseIdentifier:@"ProdDetailCell"];

例如:

_tableView = [[UITableView alloc] initWithFrame:self.view.frame];
    _tableView.dataSource = self;
    _tableView.delegate = self;
    _tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
    [self.tableView registerClass:[MAYMiaoshaCell class] forCellReuseIdentifier:cellid];
    //初步预测cell高度
    self.tableView.estimatedRowHeight = 165;
    //是否开启调试模式
    self.tableView.fd_debugLogEnabled = YES;
    //是否允许缓存
    self.cellHeightCacheEnabled = NO;
    [self.view addSubview:self.tableView];
    [self requestMiaoshaProduct];

2.在-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath方法中:

//self.cellHeightCacheEnabled 是否允许cache
if (self.cellHeightCacheEnabled) {
       
        return [self.tableView fd_heightForCellWithIdentifier:cellid cacheByIndexPath:indexPath configuration:^(MAYMiaoshaCell *cell) {
            [self configureCell:cell atIndexPath:indexPath];
        }];
    } else
    {
        return [self.tableView fd_heightForCellWithIdentifier:cellid configuration:^(MAYMiaoshaCell *cell) {
            [self configureCell:cell atIndexPath:indexPath];
        }];
    }

3.在你的cell中用Masonry去做控件的约束,如:
