iOS麦克风录制并以.wav或.cad格式保存到电话

问题描述

有一个记录电话屏幕的示例代码:

// Copyright 2016 Mail.Ru Group. All Rights Reserved.

#include "PsReplayKitPrivatePCH.h"

#import "IOS/PsReplayKitDelegate.h"

using namespace std;

@implementation PsReplayKitDelegate

@synthesize streamController;
/** Recording */
    
    - (void)StartRecording
    {
        dispatch_async(dispatch_get_main_queue(),^{
            RPScreenRecorder *sharedRecorder = RPScreenRecorder.sharedRecorder;
            if (sharedRecorder) {
                if (sharedRecorder.recording)
                {
                    return;
                }
    
                sharedRecorder.delegate = self;
                if ([sharedRecorder respondsToSelector:@selector(startRecordingWithHandler:)]) {
                    // iOS 10+
                    [sharedRecorder startRecordingWithHandler:^(NSError *error) {
                        if (error) {
                            NSLog(@"startScreenRecording: %@",error.localizedDescription);
                        }
                    }];
                }
            }
        });
    }
    
    - (void)StopRecording
    {
        dispatch_async(dispatch_get_main_queue(),^{
            RPScreenRecorder *sharedRecorder = RPScreenRecorder.sharedRecorder;
            if (sharedRecorder) {
                if (!sharedRecorder.recording)
                {
                    return;
                }
    
                [sharedRecorder stopRecordingWithHandler:^(RPPreviewViewController *previewViewController,NSError *error) {
                    if (error) {
                        NSLog(@"stopScreenRecording: %@",error.localizedDescription);
                    }
    
                    if (previewViewController) {
                        previewViewController.previewControllerDelegate = self;
    
                        previewViewController.modalPresentationStyle = UIModalPresentationFullScreen;
    
                        [[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:previewViewController animated:YES completion:nil];
                    }
                }];
            }
        });
    }

但是我需要记录麦克风中的声音并保存。 如何使用这两个函数的示例从麦克风调用录音,以便第二个Stop Recording()函数以字符串格式返回创建声音的路径? 我从未使用过obj-c语言。请更详细地描述答案。谢谢。
