Creating a Play/Pause button for AVPlayer in another View Controller - ios

Question

I am creating a Play/Pause button for an AVPlayer, but the actual player is in a UIView and the button is in the UIViewController where I am creating an instance of the player. The video plays if I simply put [self.player play]; in the code for the player, but when I try to control playing and pausing from the button it doesn't.
Here is the code:
-(IBAction)playPauseButtonClicked:(id)sender
{
PlayerView *player = [[PlayerView alloc] init];
if (self.playing == YES)
{
[player.player pause];
self.playing = NO;
NSLog(#"Pause");
}
else
{
[player.player play];
NSLog(#"Play");
self.playing = YES;
}
// UIButton *theButton = (UIButton *)sender;
//
// self.playing = !self.playing;
// [theButton setImage:self.playing ? #"pauseImage.png":#"playImage.png" forState:UIControlStateNormal];
}

Answer 1

You have to study well about Object Oriented Concepts and Object communication.
You are creating the PlayerView class object inside your playPauseButtonClicked again.
Instead, you have to pass the existing PlayerView object into the class that contains playPauseButtonClicked method.
Example:
Class A:
ClassB *classB = [[ClassB alloc] init];
classB.player = self.player;
Class B:
.h file
#property (nonatomic,weak) PlayerView *player;
.m file
-(IBAction)playPauseButtonClicked:(id)sender {
if (self.player.playing == YES)
{
[self.player pause];
self.player.playing = NO;
NSLog(#"Pause");
}
else
{
[self.player play];
NSLog(#"Play");
self.player.playing = YES;
}
}

Answer 2

First You pass your PlayerView Object to next View Controller
And In FirstViewController.h and SecondViewController.h file declare object of PlayerView
Such As
#property (nonatomic,retain) PlayerView *player;
And when navigate from first view controller to second view controller inlude this code:
SecondViewController *obj = [[SecondViewController alloc]init];
obj.player = self.player ;
Now In -(IBAction)playPauseButtonClicked:(id)sender Method of second view controller
Remove The Line from Code : PlayerView *player = [[PlayerView alloc] init];
because a above line create new object of Player View instead of object of previous view controller AVPlayer Object write this updated method
-(IBAction)playPauseButtonClicked:(id)sender {
if (self.playing == YES)
{
[player.player pause];
self.playing = NO;
NSLog(#"Pause");
}
else
{
[player.player play];
NSLog(#"Play");
self.playing = YES;
}
}
