  • 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

#import <Foundation/Foundation.h>

NS_ASSUME_NONNULL_BEGIN

@interface KTVHTTPCacheManager : NSObject

+ (instancetype)sharedManager;

///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

NS_ASSUME_NONNULL_END

#import "KTVHTTPCacheManager.h"
#import "KTVHTTPCache/KTVHTTPCache.h"

@implementation KTVHTTPCacheManager

+ (instancetype)sharedManager {
    static KTVHTTPCacheManager *sharedInstance = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        sharedInstance = [[self alloc] init];
        
        // 1.启动本地代理服务器
        NSError *error = nil;
        [KTVHTTPCache proxyStart:&error];
        if (error) {
            NSLog(@"Error starting proxy: %@", error);
        }
        
        // 缓存最大限制
        //[KTVHTTPCache cacheSetMaxCacheLength:1024*1024*500]; //500M
        [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) {
            return [NSURL URLWithString:components[0]];
        }];
    }
    
    NSURL *videoURL = [NSURL URLWithString:urlStr];
    // 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];
    return ll;
}

- (void)clearAllCache{
    [KTVHTTPCache cacheDeleteAllCaches];
}

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

#import "ZFPlayerVC.h"

#import <ZFPlayer/ZFAVPlayerManager.h>
//#import <ZFPlayer/ZFPlayerControlView.h>
#import "ZFKWPlayerControlView.h" //自定义控制层
#import <ZFPlayer/UIView+ZFFrame.h>
#import <ZFPlayer/UIImageView+ZFCache.h>
#import <ZFPlayer/ZFPlayerConst.h>
