(OSStatus error -43.)

need an urgent reply

here is my code

-(IBAction)playevent{

VoiceRecorderAppDelegate *appDelegate=(VoiceRecorderAppDelegate*)[[UIApplication sharedApplication]delegate];

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];
NSString *fullpath = [documentsDir stringByAppendingPathComponent:appDelegate.filenamefrompath];

NSFileManager *fileManager = [NSFileManager defaultManager];

// Check if the database has already been created in the users filesystem
BOOL success = [fileManager fileExistsAtPath:fullpath];

// If the database already exists then return without doing anything
if(success) { NSLog(@"Yes exists"); }else{ NSLog(@"no"); }


//return [documentsDir stringByAppendingPathComponent:appDelegate.filenamefrompath];
NSError* err;
NSLog(@"%@",fullpath);
player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:fullpath] error:&err];


//NSString *filePath = [[NSBundle mainBundle] pathForResource:appDelegate.filenamefrompath ofType:@"aif"];

// NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath]; // player = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];

NSLog(@"%@",appDelegate.filenamefrompath);
player.delegate = self;

if( err ){
    //bail!
    NSLog(@"Failed with reason: %@", [err localizedDescription]);
}


[player play];

}

Please check my code for error

The code looks OK on the surface

Strangely tracking down the errors definitions is not entirely easy

They are in MacErrors.h

fnfErr = -43, /*File not found*/

Can you verify that the URL you are feeding the player in [NSURL fileURLWithPath:fullpath] is valid.

And more to the point is the file you are trying to play there in the Sim folder?

and off topic if this is supposed to be an IBAction then the signature should be
-(IBAction)playevent:(id)sender
