将AVAudioRecorder发送到服务器iOS

Question

我在过去几天尝试将一个本地保存的sounde记录上传到服务器(用一个php文件将其保存到服务器上).问题是我找不到办法做到这一点.

在录制声音(AVAudioRecorder)时,它会保存在"NSTemporaryDirectory()"中:

NSURL *temporaryRecFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"VoiceFile"]]];

现在,我检查答案的地方都是使用ASIHTTPRequest.但问题是ios6不支持它.

还有一些其他的库,但无论我尝试什么和如何,没有任何作用.如果有人能帮助我,我会很高兴...

这是我的代码:

ViewController.h

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import <CoreAudio/CoreAudioTypes.h>

@interface ViewController : UIViewController <AVAudioRecorderDelegate,AVAudioPlayerDelegate>
{
    UIButton *recordButton;
    UIButton *playButton;
    UIButton *uploadFile;
    UILabel *recStateLabel;
    BOOL isNotRecording;

    NSURL *temporaryRecFile;
    AVAudioRecorder *recorder;
    AVAudioPlayer *player;
}

@property (nonatomic,retain) IBOutlet UIButton *uploadFile;
@property (nonatomic,retain) IBOutlet UIButton *playButton;
@property (nonatomic,retain) IBOutlet UIButton *recordButton;
@property (nonatomic,retain) IBOutlet UILabel *recStateLabel;

-(IBAction)recording;

该ViewController.m包括一些测试,我已经与图书馆等制成STHTTPRequest和AFNetworking

Answer 1

使用 AFNetworking 进行一些更改以使一切正常运行：

• 用于appendPartWithFileURL:name:fileName:mimeType:error:避免将歌曲数据加载到内存中。
• 正如 @glenwayguy 建议的那样，使用单例模式来保留对 AFHTTPClient 的静态引用。否则，您将面临操作过早解除分配的风险。
• 您应该使用AFHTTPClient -HTTPRequestOperationWithRequest:success:failure:来调试服务器响应。您提到您的上传进度块没有触发；您的服务器可能返回 500、400 或 404 错误。
