Need to stop AVPlayer before playing new stream - ios

Question

I have On-line Radio app. Located on the first viewController (tableView) audio streams. Audio streams are made as a table. By clicking on the name of the stream screen opens with AVpalyer. The problem is that when opening the second stream, the ашкые stream is played simultaneously. How to make so that would be played if one thread, and the second was turned down?
avplayer:
#interface RadioViewController ()
#end
#implementation RadioViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
NSString *restorationId = self.restorationIdentifier;
NSString *streamId = _detail.label;
NSString* identifer = [restorationId stringByAppendingString: streamId];
NSLog(#"%#", identifer);
self.title = apptitle;
self.streamLabel.text = _detail.label;
//Определение потока
NSString *streamURL;
if (_detail.label == #"ПЕРВЫЙ"){
streamURL = streamURLpervyj;
} if (_detail.label == #"РОК") {
streamURL = streamURLrok;

streamURL = streamURLbit;

streamURL = streamURLretro;

[alert show];
} else {

}

Answer 1

You can decleare avplayer object "music" in your appdelegate then access it by this way
AppDelegate *mainDelegate = [UIApplication sharedApplication].delegate;
[mainDelegate.music pause];
mainDelegate.music = nil;
when you want to start new stream or before alloc init

Answer 2

StreamViewController.h
#interface APStreamsViewController : UIViewController <UITableViewDataSource>
{
AVPlayer *musicSegue;
}
StreamViewController.m
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
if (indexPath) {
APStreamsData *item = [_data objectAtIndex:indexPath.row];
[segue.destinationViewController setDetail:item];
}
RadioViewController *music = [segue destinationViewController];
[music setMusic: musicSegue];
}
RadioViewController.h
#property (nonatomic, strong) AVPlayer *music;
And in RadioViewController change music to _music )))
