沒怎么研究視頻播放器，就在網上找了個，鏈接：https://github.com/835239104/KrVideoPlayerPlus

下載AFNetworking,

1.下載最新版的會報錯，沒有引入相關庫

2.AFSecurityPolicy.m中：注釋了一部分代碼

#PRagma mark - 這里改了 －－－－－－#warning - 這里改了 －－－－－－－－//#if !TARGET_OS_IOS && !TARGET_OS_WATCH//static NSData * AFSecKeyGetData(SecKeyRef key) {//    CFDataRef data = NULL;////    __Require_noErr_Quiet(SecItemExport(key, kSecFormatUnknown, kSecItemPemArmour, NULL, &data), _out);////    return (__bridge_transfer NSData *)data;////_out://    if (data) {//        CFRelease(data);//    }////    return nil;//}//#endifstatic BOOL AFSecKeyIsEqualToKey(SecKeyRef key1, SecKeyRef key2) {//#if TARGET_OS_IOS || TARGET_OS_WATCH    return [(__bridge id)key1 isEqual:(__bridge id)key2];//#else//    return [AFSecKeyGetData(key1) isEqual:AFSecKeyGetData(key2)];//#endif}

3.實現邊下邊播（我用的是一邊在網上看一邊下載，所以會有點卡）
