iOS AVAudioRecorder record失败的问题

Question

self.audioRecorder = [[AVAudioRecorder alloc] initWithURL:audioRecordingURL settings:[self audioRecordingSettings] error:&error];
[self.audioRecorder prepareToRecord];
[self.audioRecorder record];

在模拟器上prepareToRecord和record都返回YES,但是在真机上record返回NO,请问可能是什么原因？

Answer 1

请问你解决了吗 我也遇到了这种问题

Answer 2

AVAudioSession.sharedInstance().requestRecordPermission { (granted) in

if(granted){

print("已授权")

}else{

print("未授权")

}

}

do{

if #available(iOS 10.0, *) {

try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playAndRecord, mode: AVAudioSession.Mode.default, options: AVAudioSession.CategoryOptions.defaultToSpeaker)

}else{

try! AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playAndRecord, options: AVAudioSession.CategoryOptions.defaultToSpeaker)

}

}catch{

}
当失败的时候再调一下这个方法，就可以了

Answer 3

真机prepareToRecord成功，record就失败了，搞不懂。
