1、懒加载一个AVAudioRecorer类对象
2、设置保存的沙盒地址
3、将沙盒的地址转换成NSURl对象
4、用字典设置属性
5、创建对象
6、代码如下
//// ViewController.m// 录音//// Created by 韩燕辉 on 16/9/7.// Copyright © 2016年 hyh. All rights reserved.//#import "ViewController.h"#import@interface ViewController ()

/**

-(AVAudioRecorder *)recorder
{
if (_recorder == nil) {
NSString *path = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *filePath = [path stringByAppendingPathComponent:@"123.caf"];
self.pathUILable.text = filePath;
NSLog(@"%@",filePath);
NSURL *url = [NSURL URLWithString:filePath];
NSDictionary *settingRecorder = @{AVFormatIDKey:@(kAudioFormatLinearPCM),AVSampleRateKey : @(8000)};
self.recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settingRecorder error:nil];
}
return _recorder;
}
/**

*/
- (IBAction)recorder:(id)sender {
[self.recorder record];
}
- (IBAction)stopRecorder:(id)sender {
[self.recorder stop];
}
@end
