录音的实现

- 注意:

正确的沙盒路径

#import "ViewController.h"#import@interface ViewController ()

@property(nonatomic,strong) AVAudioRecorder * recoder ;

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

//准备文件路径

NSString * path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:@"123.caf"];

//

//    NSString * path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:@"123.caf"];

//

NSURL * url = [NSURL fileURLWithPath:path];

NSLog(@"%@",url);

self.recoder = [[AVAudioRecorder alloc]initWithURL:url settings:nil error:nil];

[self.recoder prepareToRecord];

}

- (IBAction)start:(id)sender {

[self.recoder record];

}

- (IBAction)pause:(id)sender {

[self.recoder pause];

}

- (IBAction)stop:(id)sender {

[self.recoder stop];

}

@end
