Upload AVAudioRecorder to iOS server

I have been trying for the past few days to upload a locally stored sound recording to the server (which transfers it using a php file and stores it on the server). The problem is that I cannot find a way to do this.

During sound recording (AVAudioRecorder), it saves in "NSTemporaryDirectory ()":

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

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

There are several other libraries for it, but nothing works no matter what and how I try. I would love it if someone helped 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; -(IBAction)recording; -(IBAction)playback; -(IBAction)upload; @end

ViewController.m

 #import "ViewController.h" #import <AVFoundation/AVFoundation.h> #import "STHTTPRequest.h" @interface ViewController () @end @implementation ViewController @synthesize recordButton,playButton,uploadFile,recStateLabel; -(IBAction)recording { if(isNotRecording) { isNotRecording = NO; [recordButton setTitle:@"Stop" forState:UIControlStateNormal]; playButton.hidden = YES; recStateLabel.text = @"Recording"; temporaryRecFile = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"VoiceFile"]]]; NSDictionary *recordSettings = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:AVAudioQualityMin], AVEncoderAudioQualityKey, [NSNumber numberWithInt:16], AVEncoderBitRateKey, [NSNumber numberWithInt: 2], AVNumberOfChannelsKey, [NSNumber numberWithFloat:44100.0], AVSampleRateKey, nil];

[recordButton setTitle:@"Rec" forState:UIControlStateNormal]; playButton.hidden = NO; recStateLabel.text = @"Not Recording"; [recorder stop]; } } -(IBAction)playback { player = [[AVAudioPlayer alloc]initWithContentsOfURL:temporaryRecFile error:nil]; //player.volume = 1; [player setVolume: 1.0]; [player play]; } -(IBAction)upload { NSLog(@"upload"); recStateLabel.text = @"Uploading"; NSData *data = [NSData dataWithContentsOfFile:NSTemporaryDirectory()];

ViewController.m includes some tests that I have done with libraries like STHTTPRequest and AFNetworking

this line of code works fine for me

Now I have posted all my code for recording, saving, playing back and publishing on the server

Hope this works for u

A few changes to work with AFNetworking:

  • Use appendPartWithFileURL:name:fileName:mimeType:error: to not load your song data into memory.
  • As suggested by @glenwayguy, use the singleton pattern to keep a static link to your AFHTTPClient. Otherwise, you risk that operations will be prematurely released.
  • You should use AFHTTPClient -HTTPRequestOperationWithRequest:success:failure: to debug the server response. You mentioned that your download progress block did not fire; it may happen that your server returns a 500, 400 or 404 error.

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

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

:

  NSData *data = [NSData dataWithContentsOfFile:temporaryRecFile];
