下面是索引路径中行的单元格的完整代码 - 此处表视图为多个自定义单元格，应根据值返回。滚动表视图滞后很多..我使用YYWebimage进行图像加载，并且单元格的内容不断变化，需要显示表格视图行高的高度，

您可以为自定义单元格使用子类。由于每行都有很多自定义，因此可以为每一行创建基本单元类的子类。
对于设置数据，您可以创建数据模型对象并创建行类的实例。然后你可以从cellforRowAtIndexpath设置数据模型，比如
CustomRowCell *rowCell = [[CustomRowCell alloc] init];
rowCell.dataSource = [yourDictionary objectForKey:@"key"]// yourArray[indexPath.row];
还可以使用调度队列进行服务调用。
我希望它有所帮助！
