ASAudioWaveformView

示例

要运行示例项目，请先克隆仓库，然后从示例目录运行 pod install

要求

swift 5.0+

安装

ASAudioWaveformView 可通过 CocoaPods 获取。要安装它，只需在 Podfile 中添加以下行

pod 'ASAudioWaveformView'

用法

有两种创建波形视图的方式，波形将自动调整以适应框架

1. 初始化时设置框架。完成是可选的

   let wave = ASAudioWaveformView.create(frame: CGRect(x: 0, y: 40, width: 200, height: 100)) { (config) in
       let url = Bundle.main.url(forResource: "test", withExtension: "mp3")
       config.audioURL(url).maxSamplesCount(500).fillColor(.systemTeal)
   } completion: { (empty) in
       print("-->draw Complete ,empty: \(empty)")
   }

2. 如果你使用自动布局或在稍后设置框架。完成是可选的

   let wave = ASAudioWaveformView()
   wave.createWaveform { (config) in
           let url = Bundle.main.url(forResource: "test", withExtension: "mp3")
           config.audioURL(url).positionType(.top).fillColor(.green)
   } completion: { (empty) in
       print("-->draw Complete ,empty: \(empty)")
   }

配置波形

    /// config waveform postion, the default is center
    public func positionType(_ type: ASAudioWaveformView.PositionType) -> ASAudioWaveformConfig

    /// config waveform content style, the default is polyline
    public func contentType(_ type: ASAudioWaveformView.ContentType) -> ASAudioWaveformConfig

    /// config waveform fill color, the default is yellow
    public func fillColor(_ color: UIColor) -> ASAudioWaveformConfig

    /// config waveform audio source
    public func audioURL(_ URL: URL?) -> ASAudioWaveformConfig

    /// config max samples count, the default is 1000
    public func maxSamplesCount(_ count: Int) -> ASAudioWaveformConfig
    
    /// Specifies a range of time that may limit the temporal portion of the receiver's asset from which media data will be read.The default value of timeRange is CMTimeRangeMake(kCMTimeZero, kCMTimePositiveInfinity).
    public func timeRange(_ range: CMTimeRange) -> ASAudioWaveformConfig

1. 位置类型居中，内容类型折线

   

2. 位置类型顶部，内容类型折线

   

3. 位置类型底部，内容类型折线

   

4. 位置类型居中，内容类型单行

   

使用不同的音频URL重新加载

波形将自动调整以适应框架

/// Refresh waveform by audio url
public func refreshWaveform(with audioURL: URL?)
