【day1001_MoviePlayer】：视频播放
需要导入MediaPlayer.framework
- (void)viewDidLoad { [super viewDidLoad]; NSURL *url = [NSURL fileURLWithPath:@"/Users/tarena/yz/李明杰/OC视频/ARC/28-ARC04-循环引用.mp4"]; self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url]; self.moviePlayer.view.frame = CGRectMake(0, 100, 320, 200); // [self.moviePlayer setControlStyle:MPMovieControlStyleNone]; // 隐藏视频操作 [self.moviePlayer play]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playFinishedAction) name:MPMoviePlayerPlaybackDidFinishNotification object:Nil]; [self.view addSubview:self.moviePlayer.view]; } -(void)playFinishedAction{ NSLog(@"播放完成"); } - (IBAction)clicked:(UIButton *)sender { // [self.moviePlayer pause];// 暂停 // 准备播放 把数据加载到内容 // [self.moviePlayer prepareToPlay]; UIImage *image = [self.moviePlayer thumbnailImageAtTime:self.moviePlayer.currentPlaybackTime timeOption:MPMovieTimeOptionExact]; self.imageView.image = image; }
【day1002_netWork】：tcpSocket
要导入一个类AsyncSocket，在ARC模式下需要将该类的.m文件上附加-fno-objc-arc（不使用arc模式）
- (void)viewDidLoad { [super viewDidLoad]; self.fileData = [NSMutableData data]; // 创建服务端对象 self.socketServer = [[AsyncSocket alloc] initWithDelegate:self]; // 设置端口号 [self.socketServer acceptOnPort:8000 error:Nil]; } // 接收新的服务端 接收到客户端发送的socket 相当于是客户端和服务端之间的通道 -(void)onSocket:(AsyncSocket *)sock didAcceptNewSocket:(AsyncSocket *)newSocket{ NSLog(@"接收到客户端发送的连接"); self.socketNew = newSocket; } // 连接到客户端 -(void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port{ NSLog(@"连接到客户端:%@",host); [self.socketNew readDataWithTimeout:-1 tag:0]; // 读取数据 } // 接收到客户端数据 注意：当文件大时，此方法只会调用一次读取一次数据，不会自动调用 -(void)onSocket:(AsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag{ self.fileSize += data.length; [self.fileData appendData:data]; NSLog(@"接收到数据长度:%d,%d",data.length,self.fileSize); if (self.fileData.length == 4186188) { [self.fileData writeToFile:@"/Users/tarena/yz/第三阶段(高级UI)/day10/a.mp3" atomically:YES]; } [self.socketNew readDataWithTimeout:-1 tag:0]; } // 断开连接 -(void)onSocketDidDisconnect:(AsyncSocket *)sock{ } // 客户端 - (IBAction)buttonAction:(UIButton *)sender { // 创建客户端 self.socketClient = [[AsyncSocket alloc] initWithDelegate:self]; // 发送连接 // 连接服务端 [self.socketClient connectToHost:@"localhost" onPort:8000 error:Nil]; NSLog(@"发送连接"); // 发送数据 NSData *data = [NSData dataWithContentsOfFile:@"/Users/tarena/yz/第三阶段(高级UI)/day10/musics/泡沫.mp3"]; [self.socketClient writeData:data withTimeout:-1 tag:0]; } -(void)onSocket:(AsyncSocket *)sock didWriteDataWithTag:(long)tag{ NSLog(@"发送完成"); }
