短視頻app源碼開發(fā)：仿抖音短視頻熱門頁面的實現

1、短視頻app源碼開發(fā)：仿抖音短視頻熱門頁面的實現在短視頻app源碼開發(fā)中，仿抖音短視頻熱門頁面的實現只不過是多了一個由UICollectionView呈現多個視頻圖片的中間界面，點開后播放視頻界面其實就是推薦界面，所以這里并沒有什么核心難點，只是簡單介紹下這個collectionView就好了。#importHotVideoVC.h#import#importRecommendVideoVC.h#importNearbyVideoModel.h#importVideoCollectionCell.h#importAFNetworking.hinterfaceHotVideoVC()proper
