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）
/** * 下載文件 */- (void)downloadFileURL:(NSString *)aUrl savePath:(NSString *)aSavePath fileName:(NSString *)aFileName tag:(NSInteger)aTag{ NSFileManager *fileManager = [NSFileManager defaultManager]; //檢查本地文件是否已存在 NSString *fileName = [NSString stringWithFormat:@"%@/%@", aSavePath, aFileName]; //檢查附件是否存在 if ([fileManager fileExistsAtPath:fileName]) { [self addVideoPlayerWithURL:[NSURL fileURLWithPath:fileName]]; }else{ //創建附件存儲目錄 if (![fileManager fileExistsAtPath:aSavePath]) { [fileManager createDirectoryAtPath:aSavePath withIntermediateDirectories:YES attributes:nil error:nil]; }// [self addVideoPlayerWithURL:[NSURL fileURLWithPath:fileName]]; [self addVideoPlayerWithURL:[NSURL URLWithString:aUrl]]; //下載附件 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]; //下載進度控制 [operation setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) { NSLog(@"is download：%f", (float)totalBytesRead/totalBytesExpectedToRead); }]; //已完成下載 [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responSEObject) {// NSData *audioData = [NSData dataWithContentsOfFile:fileName]; NSLog(@"完成下載"); //設置下載數據到res字典對象中并用代理返回下載數據NSData } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"下載失敗"); //下載失敗 }]; [operation start]; }}
注意：從本度讀取路徑：[NSURL fileURLWithPath:fileName]
在網上讀取路徑：[NSURL URLWithString:aUrl]
