## Cocoapods 安装
### 在项目目录下创建 Podfile 文件, 如果没有的话请执行
```
pod init
```
### 添加Pod
```ruby
# Uncomment the next line to define a global platform for your project
platform :ios, &#039;9.0&#039;

target &#039;QLive&#039; do
  # Uncomment the next line if you&#039;re using Swift or would like to use dynamic frameworks
  use_modular_headers!

# Pods for QLive
  pod &#039;NodeMediaClient&#039;, &#039;~> 4.0&#039; 
end

```
### 安装
```shell
pod install
```

## 简单用法

### 使用NodePlayer进行播放
```
#import "PlayViewController.h"
//引入头文件
#import <NodeMediaClient/NodeMediaClient.h>

@interface PlayViewController ()
//定义播放器对象
@property (nonatomic, strong) NodePlayer *np;

@end

@implementation PlayViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // 初始化，如果有授权码请填入
    _np = [[NodePlayer alloc] initWithLicense:@""];
    //设置日志等级
    [_np setLogLevel:1];
    //开启硬件加速
    [_np setHWAccelEnable:YES];
    //如果需要视频内容解码，请填入16位密码
    [_np setCryptoKey:@""];
    //设置播放缓冲，单位毫秒
    [_np setBufferTime:1000];
    //设置视频缩放模式
    [_np setScaleMode:1];
    //设置音量
    [_np setVolume:1.0f];
    // 绑定视图
    [_np attachView:self.view];
    //开始播放
    [_np start:@"rtmp://live.nodemedia.cn/live/b480_264"];
}

-(void)viewWillDisappear:(BOOL)animated {
    // 移除视图
    [_np detachView];
    //停止播放
    [_np stop];
    //标记释放
    _np = nil;
}

@end

```

### 使用NodePublisher进行摄像头推流

**请确认描述条目&#039;Privacy - Microphone Usage Description&#039; 和 &#039;Privacy - Camera Usage Description&#039; 已经添加入info.plist**

```

#import "PublishViewController.h"
//引入头文件
#import <NodeMediaClient/NodeMediaClient.h>

@interface PublishViewController ()
//定义推流器对象
@property (nonatomic, strong) NodePublisher *np;
@property (nonatomic) Boolean isStart;
@end

@implementation PublishViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    //初始化对象，如果有授权码请填入
    _np = [[NodePublisher alloc] initWithLicense:@""];
    //设置日志等级
    [_np setLogLevel:NM_LOGLEVEL_DEBUG];
    //开启硬件加速
    [_np setHWAccelEnable:YES];
    //开启麦克风降噪
    [_np setDenoiseEnable:YES];
    //开启Enhanced Rtmp推流，仅对H265有效
    [_np setEnhancedRtmp:YES];
    //如果需要，设置推流内容加密，16位密码
    [_np setCryptoKey:@""];
    //设置音频参数
    [_np setAudioParamWithCodec:NMC_CODEC_ID_AAC profile:NMC_PROFILE_AUTO samplerate:48000 channels:1 bitrate:64*1000];
    //设置视频方向
    [_np setVideoOrientation:VIDEO_ORIENTATION_PORTRAIT];
    //设置视频关键帧间隔，单位秒
    [_np setKeyFrameInterval:3];
    //设置视频参数
    [_np setVideoParamWithCodec:NMC_CODEC_ID_H264 profile:NMC_PROFILE_AUTO width:540 height:960 fps:30 bitrate:2000*1000];
    //绑定摄像头预览视图
    [_np attachView:self.view];
    //打开摄像头预览
    [_np openCamera:true];
}

-(void)viewWillDisappear:(BOOL)animated {
    //关闭摄像头预览
    [_np closeCamera];
    //移除视图
    [_np detachView];
    //停止推流
    [_np stop];
    //标记释放
    _np = nil;
}

- (IBAction)publishAction:(id)sender {
    if(_isStart) {
        [_np stop];
        dispatch_async(dispatch_get_main_queue(), ^{
            [sender setTitle:@"Start Publish" forState:UIControlStateNormal];
        });
    }else {
        [_np start:@"rtmp://live.nodemedia.cn/live/demo"];
        dispatch_async(dispatch_get_main_queue(), ^{
            [sender setTitle:@"Stop Publish" forState:UIControlStateNormal];
        });
    }
    _isStart = !_isStart;
}

@end

```
