can't able to save recorded audio iOS? - objective-c

Question

I Want to save the recorded audio in local documents directory
After that i want to play the Saved audio file
Audiofile is not created in documents directory?
I've tried with the following code What I am doing wrong??
NSString *temp1=[NSString stringWithFormat:#"%#.m4a",temp];
NSLog(#"=====>>%#",temp1);
NSArray *pathComponents=[NSArray arrayWithObjects:[NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES)lastObject],temp1, nil];
NSURL *outputFileURL=[NSURL fileURLWithPathComponents:pathComponents];
if (isRecording==NO) {
isRecording=YES;
NSLog(#"recording started");
session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryPlayAndRecord error:nil];
// Define the recorder setting
NSMutableDictionary *recordSetting = [[NSMutableDictionary alloc] init];
[recordSetting setValue:[NSNumber numberWithInt:kAudioFormatMPEG4AAC] forKey:AVFormatIDKey];
[recordSetting setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey];
[recordSetting setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey];
// Initiate and prepare the recorder
recorder = [[AVAudioRecorder alloc] initWithURL:outputFileURL settings:recordSetting error:NULL];
recorder.delegate = self;
recorder.meteringEnabled = YES;
[recorder prepareToRecord];
[session setActive:YES error:nil];
// Start recording
[recorder record];
}
else
{
NSLog(#"recording stopped");
[recorder stop];
NSData *audioData=[NSData dataWithContentsOfURL:outputFileURL];
[audioData writeToURL:outputFileURL atomically:YES];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:outputFileURL error:nil];
[player prepareToPlay];
[player play];
[player setVolume:1.0];
isRecording=NO;
}

Try this code
-(IBAction)btnS1AudioPressed:(id)sender
{
audioSession = [AVAudioSession sharedInstance];
NSError *err = nil;
[audioSession setCategory :AVAudioSessionCategoryPlayAndRecord error:&err];
if(err)
{
NSLog(#"audioSession: %# %d %#", [err domain], [err code], [[err userInfo] description]);
return;
}
[audioSession setActive:YES error:&err];
err = nil;
if(err)
{
NSLog(#"audioSession: %# %d %#", [err domain], [err code], [[err userInfo] description]);
return;
}
NSMutableDictionary *recordSetting = [[NSMutableDictionary alloc] init];
[recordSetting setValue :[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey];
[recordSetting setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey];
[recordSetting setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey];
[recordSetting setValue :[NSNumber numberWithInt:16] forKey:AVLinearPCMBitDepthKey];
[recordSetting setValue :[NSNumber numberWithBool:NO] forKey:AVLinearPCMIsBigEndianKey];
[recordSetting setValue :[NSNumber numberWithBool:NO] forKey:AVLinearPCMIsFloatKey];
NSString *AudioName=[NSString stringWithFormat:#"TestAudio.caf"];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
audioPath = [documentsDirectory stringByAppendingPathComponent:AudioName];
NSURL *url = [NSURL fileURLWithPath:audioPath];
err = nil;
NSData *audioData = [NSData dataWithContentsOfFile:[url path] options: 0 error:&err];
if(audioData)
{
NSFileManager *fm = [NSFileManager defaultManager];
[fm removeItemAtPath:[url path] error:&err];
}
recorder = [[ AVAudioRecorder alloc] initWithURL:url settings:recordSetting error:&err];
if(!recorder)
{
NSLog(#"recorder: %# %d %#", [err domain], [err code], [[err userInfo] description]);
UIAlertView *alert =
[[UIAlertView alloc] initWithTitle: #"Warning"
message: [err localizedDescription]
delegate: nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
return;
}
[recorder setDelegate:self];
[recorder prepareToRecord];
recorder.meteringEnabled = YES;
BOOL audioHWAvailable = audioSession.inputIsAvailable;
if (! audioHWAvailable)
{
UIAlertView *cantRecordAlert =
[[UIAlertView alloc] initWithTitle: #"Warning"
message: #"Audio input hardware not available"
delegate: nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[cantRecordAlert show];
return;
}
[recorder recordForDuration:(NSTimeInterval) 10000];
}
- (IBAction) stopRecording:(id)sender
{
[recorder stop];
}

I've found the mistake I made
NSArray *pathComponents=[NSArray arrayWithObjects:[NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES)lastObject],temp1, nil];
In the above code I used NSDocumentationDirectory instead of NSDocumentsDirectory
