高级UIKit-08(TCPSocket)

【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(, , , );

//    [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: 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:- tag:]; // 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 == ) {

        [self.fileData writeToFile:@"/Users/tarena/yz/第三阶段(高级UI)/day10/a.mp3" atomically:YES];

    }

    [self.socketNew readDataWithTimeout:- tag:];

}

// 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: 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:- tag:];

}

-(void)onSocket:(AsyncSocket *)sock didWriteDataWithTag:(long)tag{

    NSLog(@"发送完成");

}

属性不能以new开头
