    【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");
    
    }
