Sending AVAudioRecorder to server iOS

问题:

I am trying for the past few days to upload a locally saved sounde record to a server (which handels it with a php file and saves it to the server). the problem is that I can't find a way to do that.

While recording the sound (AVAudioRecorder) it saves at a "NSTemporaryDirectory()":

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

Now, everywhere I checked the answer was to use ASIHTTPRequest. but the problem is that it is not supported in ios6.

There are some other libraries for it but nothing works no matter what and how I try. I would love it if someone could help me...

Here is my code:

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;

i hope it will works for u

回答2:

A few changes to get everything working using AFNetworking:

• Use appendPartWithFileURL:name:fileName:mimeType:error: to avoid having to load your song data into memory.
• As suggested by @glenwayguy, use the singleton pattern to keep a static reference to your AFHTTPClient. Otherwise, you risk having operations prematurely deallocated.
• You should use AFHTTPClient -HTTPRequestOperationWithRequest:success:failure: to debug server response. You mentioned that your upload progress block was not firing; it could be that your server is returning a 500, 400, or 404 error.

回答4:

it's possible that the primary problem with this code is that in its current attempt (and in the commented out code in the attempt to assign NSData* songData when using AFNetworking) is that the line of code that in method upload should be changed from:

    NSData *data = [NSData dataWithContentsOfFile:NSTemporaryDirectory()];

to this:

    NSData *data = [NSData dataWithContentsOfFile:temporaryRecFile];
