Ios – Updating UIImage on UiBarButtonItem from identifier to image

imageiosobjective cuibarbuttonitemupdating

I am currently making an application for IOS but I am having trouble changing an image… what a shame…

The situation is like this :
I have a toolbar containing my items, and one of this items is the play button created from the identifier "Play". So I have my Play button without problem. Now I just want to change it to a pause image when I click on item and then switch again etc.
So I liked in my .h the item giving me :

@property (weak, nonatomic) IBOutlet UIBarButtonItem *play;

I tried many answers I found on this website and none of them did work on my case :/
The last one I tried was something like this : 

UIButton *button1=[UIButton buttonWithType:UIButtonTypeCustom];
[button1 setFrame:CGRectMake(10.0, 2.0, 45.0, 40.0)];
[button1 addTarget:self action:@selector(showLeft:) forControlEvents:UIControlEventTouchUpInside];
[button1 setImage:[UIImage imageNamed:@"pause.png"] forState:UIControlStateNormal];
UIBarButtonItem *button = [[UIBarButtonItem alloc]initWithCustomView:button1];
self.play = button;

I also tried :

self.play.customView = button1;

But none of them really work, I can get the image by doing 

self.view = button1;

But that only the picture (so the creation of the UIImage is okay) in the middle of the screen so….

(If you can also tell me how to go back to the play using identifier it would also be very helpful thanks a lot)

Thanks for your help.

If the button is already created and you have an outlet for it, you can simply set it like this:

UIImage* backgroundImage = [UIImage yourImage];
[self.barButtonItem setImage:backgroundImage];

Works like charm.
