Hi Guys I Got a prb in AvAudioRecorder that the sound was not recording and it was no playing and my code is in .m: #import "AudioRecorderViewController.h"

@implementation AudioRecorderViewController


 // The designated initializer.  Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
- (id)init {
    if (self = [super init]) {
        // Custom initialization

    mview = [[UIView alloc]initWithFrame:[[UIScreen mainScreen]applicationFrame]];
    startRecording =[[UIButton alloc]initWithFrame:CGRectMake(100, 100, 140, 30)];
    startRecording.backgroundColor=[UIColor redColor];
    [startRecording  setTitle:@"Start Recording" forState:UIControlStateNormal];
    //[playButton setBackgroundImage:@"images-1.png" forState:UIControlStateNormal];
    //  myButton.backgroundImage = [UIImage imageNamed:@"anyButtonBackground.png"]; 
    [startRecording addTarget:self action:@selector(startRecordingAction) forControlEvents:UIControlEventTouchUpInside];
    [mview addSubview:startRecording];

    playRecordedItem =[[UIButton alloc]initWithFrame:CGRectMake(100, 200, 140, 30)];
    playRecordedItem.backgroundColor=[UIColor redColor];
    [playRecordedItem  setTitle:@"Play" forState:UIControlStateNormal];
    //[playButton setBackgroundImage:@"images-1.png" forState:UIControlStateNormal];
    //  myButton.backgroundImage = [UIImage imageNamed:@"anyButtonBackground.png"]; 
    [playRecordedItem addTarget:self action:@selector(playRecordedItemAction) forControlEvents:UIControlEventTouchUpInside];
    [mview addSubview:playRecordedItem];
    mview.backgroundColor = [UIColor blackColor];

    toggle =  YES;
    playRecordedItem.hidden = YES;

    [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:&error];
    [audioSession setActive:YES error:&error];
    self.view = mview;
}
return self;
