    // 视频链接

    // 设置URL映射
    NSArray *components = [urlStr componentsSeparatedByString:@"?"];
    [KTVHTTPCache encodeSetURLConverter:^NSURL *(NSURL *URL) {

    }];
    
    NSURL *videoURL = [NSURL URLWithString:urlStr];
    // 2.生成代理 URL
    NSURL *proxyURL = [KTVHTTPCache proxyURLWithOriginalURL:videoURL];
    
    AVPlayer *player = [AVPlayer playerWithURL:proxyURL];
    
    
    AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
    playerLayer.frame = CGRectMake(0, 0, 300, 160);
    [self.view.layer addSublayer:playerLayer];
    [player play];
    
}

@end

但我懒得再去写一个自定义控制层，我想用ZFPlayer
先把KTVHTTPCache 简单封装成个单例

KTVHTTPCache 封装

objectivec 复制代码

#import <Foundation/Foundation.h>

///是否开启URL映射
@property (nonatomic ,assign)BOOL isConverter;
///获取视频链接
- (NSURL *)createProxyURL:(NSString *)urlStr;


///当前缓存 xxMB
- (NSString *)getAllCacheLength;
///清理所有缓存
- (void)clearAllCache;

@end

        // 1.启动本地代理服务器
        NSError *error = nil;
        [KTVHTTPCache proxyStart:&error];
        if (error) {

        }
        
        // 缓存最大限制

        [KTVHTTPCache cacheSetMaxCacheLength:1024LL*1024LL*1024LL*2LL]; //2G
        
    });
    return sharedInstance;
}



- (NSURL *)createProxyURL:(NSString *)urlStr{
    
    if (self.isConverter) {
        // 设置URL映射
        NSArray *components = [urlStr componentsSeparatedByString:@"?"];
        [KTVHTTPCache encodeSetURLConverter:^NSURL *(NSURL *URL) {

    // 2.生成代理 URL
    NSURL *proxyURL = [KTVHTTPCache proxyURLWithOriginalURL:videoURL bindToLocalhost:NO];
    return proxyURL;

- (NSString *)getAllCacheLength{
    long long int length = [KTVHTTPCache cacheTotalCacheLength];
    NSString * ll = [NSString stringWithFormat:@"%lld MB",length/1024/1024];

KTVHTTPCache + ZFPlayer/AVPlayer

使用KTVHTTPCacheManager
1. 启动本地代理服务器，并设置URL映射
[KTVHTTPCacheManager sharedManager].isConverter = YES;
1. 获取播放链接
NSURL *proxyURL = [[KTVHTTPCacheManager sharedManager] createProxyURL:@""];
1. 然后把这个链接直接给ZFPlayer播放就行了
self.player.assetURL = proxyURL;
但是我遇到一个问题：
- 播放视频开始时经常会卡住
- 排查到卡住的时候播放状态已改变成正在播放了，但是未播放成功
- 我又不想去改 pod 中的源码，避免以后每次重新pod都要改
- 我的解决办法是，播放后延迟1秒，判断播放进度是否有回调，没有的话就重新调用一次播放
代码如下
