How to use AVPlayer in multiple view and resume controls? - iphone

Question

i create an app with xcode 4.6 on iOS 6.1 with a TabBar and 2 different tableView.
Each table view read a line form a file.plist and when tap on a row, you load a DetailView.
The DetailViewController is the same for the 2 TableView but:
If start app tap on a first button i see FirstView with my table and Audio List, if I choose one file on list I load a Detail view and listener my file very well, but if now tap on second view on TabBar i can start playing other audio file from the second view but i listen overlay to firs audio and AVplayer not override.
There my coding:
From TableView loading plist:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if([#"detailList" isEqualToString:segue.identifier]) {
NSIndexPath *index = [self.tableView indexPathForCell:sender];
[[segue destinationViewController] setSaved:[loadData objectAtIndex:index.row]];
}
}
In a detali view:
if (mysound.rate == 1.0) {
UIImage *img = [UIImage imageNamed:#"Play_BT.png"];
[control setImage:img forState:UIControlStateNormal];
[mysound pause];
} else {
UIImage *img = [UIImage imageNamed:#"Pause_BT.png"];
[control setImage:img forState:UIControlStateNormal];
NSURL *url = [NSURL URLWithString:[saved objectForKey:#"audio"]];
mysound = [[AVPlayer alloc] initWithURL:url];
[mysound setAllowsExternalPlayback:YES];
[mysound setUsesExternalPlaybackWhileExternalScreenIsActive: YES];
[mysound play];
}
}
Here incoming the issues, this code working very goog, but if tapo on tab bar and load other audio from other plist I listen Audio overlay.
How can use AVPlayer in Override the NSURL *url = [NSURL URLWithString:[saved objectForKey:#"audio"]];when change from tabbar?
Thanks.

Solved, using this code:
In my AppDelegate .h adding
#interface AppDelegate : UIResponder <UIApplicationDelegate> {
AVPlayer *MyPlayer;
}
#property (strong, nonatomic) AVPlayer *MyPlayer;
in my AppDelegate .m inside didFinishLaunchingWithOptions adding
[MySound superclass];
Now can calling a method in all app with this code directly inside a .m file:
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSURL *url = [NSURL URLWithString:[saved objectForKey:#"link"]];
appDelegate.MySound = [[AVPlayer alloc] initWithURL:url];
[appDelegate.MySound setAllowsExternalPlayback:YES];
[appDelegate.MySound setUsesExternalPlaybackWhileExternalScreenIsActive: YES];
[appDelegate.MySound play];
With this method now is possible controlling the AVPlayer evry where in the APP!!
I Hope this Help any guys ;)
