關於TableView 上放 CollectionView

1.先放張效果圖

2.如果想在TableView 上放 CollectionView, 最好要寫在TableViewCell里, 並且CollectionView的代理方法都要寫在TableViewCell里, 如果在ViewController里寫的話,會因為cell重用的問題出現崩潰, 並且注冊CollectionView的cell的時候, 會出現很多問題.

下邊是代碼:在TableView的Cell里, 寫CollectionView的代理方法, 注冊CollectionView的cell, 希望對朋友們有幫#import "SecondTableViewCell.h"#import "SecondCollectionViewCell.h#import "UrlMacro.h"#import "FiveCollectionViewCell.h"
