没怎么研究视频播放器，就在网上找了个，链接：https://github.com/835239104/KrVideoPlayerPlus
下载AFNetworking,
1.下载最新版的会报错，没有引入相关库
2.AFSecurityPolicy.m中：注释了一部分代码
#pragma mark - 这里改了 －－－－－－#warning - 这里改了 －－－－－－－－//#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.实现边下边播（我用的是一边在网上看一边下载，所以会有点卡）
/** * 下载文件 */- (void)downloadFileURL:(NSString *)aUrl savePath:(NSString *)aSavePath fileName:(NSString *)aFileName tag:(NSInteger)aTag{ NSFileManager *fileManager = [NSFileManager defaultManager]; //检查本地文件是否已存在 NSString *fileName = [NSString stringWithFormat:@"%@/%@", aSavePath, aFileName]; //检查附件是否存在 if ([fileManager fileExistsAtPath:fileName]) { [self addVideoPlayerWithURL:[NSURL fileURLWithPath:fileName]]; }else{ //创建附件存储目录 if (![fileManager fileExistsAtPath:aSavePath]) { [fileManager createDirectoryAtPath:aSavePath withIntermediateDirectories:YES attributes:nil error:nil]; }// [self addVideoPlayerWithURL:[NSURL fileURLWithPath:fileName]]; [self addVideoPlayerWithURL:[NSURL URLWithString:aUrl]]; //下载附件 NSURL *url = [[NSURL alloc] initWithString:aUrl]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; operation.inputStream = [NSInputStream inputStreamWithURL:url]; operation.outputStream = [NSOutputStream outputStreamToFileAtPath:fileName append:NO]; //下载进度控制 [operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) { NSLog(@"is download：%f", (float)totalBytesRead/totalBytesExpectedToRead); }]; //已完成下载 [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {// NSData *audioData = [NSData dataWithContentsOfFile:fileName]; NSLog(@"完成下载"); //设置下载数据到res字典对象中并用代理返回下载数据NSData } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"下载失败"); //下载失败 }]; [operation start]; }}
注意：从本度读取路径：[NSURL fileURLWithPath:fileName]
在网上读取路径：[NSURL URLWithString:aUrl]
