要解决“AVAudioEngineImpl::IOUnitConfigurationChanged() 崩溃”问题,可以尝试以下解决方法:
let engine = AVAudioEngine()
let inputNode = engine.inputNode
let outputNode = engine.outputNode
// 设置输入和输出的采样率和声道数
let inputFormat = inputNode.inputFormat(forBus: 0)
let outputFormat = outputNode.outputFormat(forBus: 0)
engine.connect(inputNode, to: engine.mainMixerNode, format: inputFormat)
engine.connect(engine.mainMixerNode, to: outputNode, format: outputFormat)
let audioSession = AVAudioSession.sharedInstance()
// 配置音频会话的类别和选项
do {
try audioSession.setCategory(.playAndRecord, mode: .default, options: [])
try audioSession.setActive(true)
} catch {
print("Failed to configure audio session: \(error)")
}
let audioSession = AVAudioSession.sharedInstance()
// 请求麦克风访问权限
audioSession.requestRecordPermission { granted in
if granted {
// 用户已授权麦克风访问
} else {
// 用户未授权麦克风访问
}
}
do {
// 执行需要音频引擎的代码
} catch let error as NSError {
print("Error: \(error.localizedDescription)")
} catch {
print("Unexpected error")
}
通过检查和调整音频引擎配置、音频会话配置、权限和异常处理,你应该能够解决“AVAudioEngineImpl::IOUnitConfigurationChanged() 崩溃”问题。如果问题仍然存在,请进一步检查你的代码和环境,或尝试通过其他方式解决。
