Unrecognized Selector in AVplayer setNumberOfLoops Method - objective-c

Question

When calling the numberOfLoops method like so:
[_player setNumberOfLoops:-1];
I get the following error:
-[AVPlayer setNumberOfLoops:]: unrecognized selector sent to instance 0x7d52d30
How can this be fixed?
Code:
Header:
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#interface ViewController : UIViewController {
}
#property (strong, nonatomic) AVAudioPlayer *player;
- (IBAction)playMusic:(id)sender;
#end
Implementation:
#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)playMusic:(id)sender {
_player = [AVPlayer playerWithURL:[NSURL URLWithString:#"http://urlpath.wav"]];
[_player setNumberOfLoops:-1];
[_player prepareToPlay];
[_player play];
}
#end
Thank you for your time,

Answer 1

You've created an instance of AVPlayer, not an instance of AVAudioPlayer. It looks like you want to be creating an AVAudioPlayer instead (as is indicated by your choice of that class for the actual player property on your class. AVAudioPlayer actually has the numberOfLoops property, while AVPlayer does not. For more information, see the documentation for AVAudioPlayer and AVPlayer.

Answer 2

AVPlayer doesn't have a numberOfLoops property. That is a property of `AVAudioPlayer. Don't ignore compiler warnings when you build your app.
Also, you defined _player to be an AVAudioPlayer but you alloc/init AVPlayer.
Change your code to:
NSError *error = nil;
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL URLWithString:#"http://urlpath.wav"] error:&error];
if (player) {
[player setNumberOfLoops:-1];
[player prepareToPlay];
[player play];
self.player = player;
} else {
NSLog(#"Error create audio player: %#", error);
}

I think that the method you are calling doesn't exist (acceosing to your error).
Try: _player.numberOfLoops=-1
