多媒体音频视频与iPad基本使用

多媒体音频视频与iPad基本使用

一、多媒体播放

　　1.配置库  -->  AVFoundation.framework

　　　　头文件   #import <AVFoundation/AVFoundation.h>

　　2.播放音频

　　（1）播放本地音频

@interface ViewController ()

{

  //  AVAudioPlayer *_player;

    UISlider *_volumeSlider;  //音量控制

//    UIProgressView *_playProgressView;  //播放进度

}

@property (nonatomic,strong) AVAudioPlayer *player;

@property (nonatomic,strong) UIProgressView *playProgressView;

#pragma mark - 播放本地音乐文件

-(void)playLocationAudio{



    NSData *data = [[NSData alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"lalala.mp3" ofType:nil]];

    

    _player = [[AVAudioPlayer alloc] initWithData:data error:nil];   //初始化

    

    __weak typeof(self) weakSelf = self;

    [self.view addSystemButtonWithFrame:CGRectMake(100, 100, 100, 30) title:@"播放" action:^(UIButton *button) {

        //

        [weakSelf.player play];

    }];  //加按钮 --> 播放

    

    [self.view addSystemButtonWithFrame:CGRectMake(100, 150, 100, 30) title:@"stop" action:^(UIButton *button) {

        //

        [weakSelf.player stop];   //注：stop , pause 暂停

        weakSelf.player.currentTime = 0;   //设置从头播放

        weakSelf.playProgressView.progress = 0;

        

    }];  //加按钮 --> stop

    

    //进度控制(UIProgressView)

    _playProgressView = [[UIProgressView alloc] initWithFrame:CGRectMake(20, 200, 280, 20)];

    [self.view addSubview:_playProgressView];

    

    [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(dealTimer:) userInfo:nil repeats:YES];

    //添加手势

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dealTap:)];

    [_playProgressView addGestureRecognizer:tap];

    

    //音量控制(UISlider)

    _volumeSlider = [[UISlider alloc] initWithFrame:CGRectMake(20, 250, 280, 20)];

    [self.view addSubview:_volumeSlider];

    _volumeSlider.maximumValue = 10;

    _volumeSlider.minimumValue = 0;

    [_volumeSlider addTarget:self action:@selector(dealSlider:) forControlEvents:UIControlEventValueChanged];



}

#pragma mark - 音量控制

-(void)dealSlider:(UISlider *)silder{



    _player.volume = _volumeSlider.value;  //调节当前音量与slider对应

}

#pragma mark - 进度控制

-(void)dealTimer:(NSTimer *)timer{



    if(_player.duration != 0){

        //进度 = 当前时间/总共时间

        _playProgressView.progress = _player.currentTime/_player.duration;

    }

}

-(void)dealTap:(UITapGestureRecognizer *)tap{



    CGPoint point = [tap locationInView:_playProgressView];

    NSLog(@"point.x = %f",point.x);

    //设置点击到的值

    double time = _player.duration * (point.x / _playProgressView.frame.size.width);

    NSLog(@"time = %f",time);

    

    _player.currentTime = time;  //

    

}

　　（2）播放在线音频

#pragma mark - 播放在线的music

-(void)audioPalyURLMusicUseDemo{



    //下载地址  http://yinyueshiting.baidu.com/data2/music/239130183/1226741191429509661128.mp3?xcode=401ee63dcc7ece3e28ee0f6f3c6ea015c3ba3c8b80064e3b

    NSString *urlStr = @"http://yinyueshiting.baidu.com/data2/music/239130183/1226741191429509661128.mp3?xcode=401ee63dcc7ece3e28ee0f6f3c6ea015c3ba3c8b80064e3b";

    _streamer = [[AudioStreamer alloc] initWithURL:[NSURL URLWithString:urlStr]];

    

    __weak typeof(self) weakSelf = self;

    [self.view addSystemButtonWithFrame:CGRectMake(100, 100, 100, 30) title:@"播放" action:^(UIButton *button) {

        //

        [weakSelf.streamer start];

    }];  //加按钮 --> 播放

    

    [self.view addSystemButtonWithFrame:CGRectMake(100, 150, 100, 30) title:@"stop" action:^(UIButton *button) {

        //

        [weakSelf.streamer stop];

        

    }];  //加按钮 --> stop



    //..........

}

　　（3）播放视频

//----------------3.播放视频-----------------------------------

    //播放本地视频文件

    //1.加库-->MediaPlayer.framework  ,头文件

#pragma mark - 播放视频文件

-(void)audioMedioUseDemo{

    //播放本地视频文件

    __weak typeof(self) weakSelf = self;

    [self.view addSystemButtonWithFrame:CGRectMake(100, 100, 100, 30) title:@"播放本地文件" action:^(UIButton *button) {

        //获取本地视频文件-->播放

        NSString *path = [[NSBundle mainBundle] pathForResource:@"dzs.mp4" ofType:nil];

        MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:path]];

        [weakSelf presentViewController:moviePlayer animated:YES completion:^{

           //

        }];

        

    }];  //加按钮 --> 播放

    

}

#pragma mark - 播放url视频文件

-(void)audioURLMedioUseDemo{

    //播放网络视频文件

    __weak typeof(self) weakSelf = self;

    [self.view addSystemButtonWithFrame:CGRectMake(100, 100, 100, 30) title:@"播放URL文件" action:^(UIButton *button) {

        //

        NSString *urlString = @"http://k.youku.com/player/getFlvPath/sid/842953390607212440d37_00/st/mp4/fileid/0300080400552FC1BC6E56087AC0925DEDEBDD-A820-CF65-A99F-02EF5D8626DD?K=d576e3f832ea0e35261e4bfe&ctype=12&ev=1&oip=1931322792&token=8474&ep=eiaWE0yOVccA4yPYij8bYyjiIHQIXP4J9h%2BFidJmALshTerJ6j%2BjtJvFS%2FlCHv5oASIPEu6F3qSSGDRgYYFLq2gQrDiuPPqR9%2FmV5a1RseYFEhEwcMujwFSWRzf1";

        MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:urlString]];

        [weakSelf presentViewController:moviePlayer animated:YES completion:^{

            //

        }];

        

    }];  //加按钮 --> 播放

    

    /******播放直播文件**********/

    //直播网址: http://219.232.160.141:5080/hls/c64024e7cd451ac19613345704f985fa.m3u8

    [self.view addSystemButtonWithFrame:CGRectMake(100, 200, 100, 30) title:@"播放直播文件" action:^(UIButton *button) {

        //

        NSString *urlString = @"http://219.232.160.141:5080/hls/c64024e7cd451ac19613345704f985fa.m3u8";

        MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:urlString]];

        [weakSelf presentViewController:moviePlayer animated:YES completion:^{

            //

        }];

        

    }];  //加按钮 --> 播放

}

二、iPad编程

// 1.ipad ,iphone 的区别 --大小，缺少硬件（电话，短信...）,适配，多了2个控件

    //ipad -->size

    CGSize size = [UIScreen mainScreen].bounds.size;

    NSLog(@"%f, %f",size.width,size.height);   //ipad2 : 768*1024

                                            //iPad Air : 768*1024

                                            //iPad Retina : 768*1024

    //适配问题: 最好弄个iPad版本

    

    /*

     2.iPad 特有控件  （2个）

        UISplitViewController   -- 分割视图控制器

        ---界面间的传值-----反向传值

        UIPopoverController  -- 弹出控制器

*/

#import "AppDelegate.h"

#import "MasterViewController.h"

#import "DetailViewController.h"



@interface AppDelegate ()

    DetailViewController *dvc = [[DetailViewController alloc] init];
