IBAction cycle through images on tap - ios

Question

I want to use an IBAction method that when on tap cycles through images. Ie one image and a button is shown unload and when the user taps the button a new image is shown in its place etc. Right now it just shows the first image in the array. When I tap the button a second time nothing happens. Can someone please help me edit this to cycle through all of my images? Thanks.
EDIT
//when i tap the button only the first image shows in the array. What should I edit from the current app?
#import "ViewController.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.
}
//Implementing our method
- (IBAction)buttonPressed
{
NSArray *imagesArray = #[#"image1.png",#"image2.png",#"image3.png",#"image4.png"];
count ++;
if(count == imagesArray.count)
{
count = 0;
}
yourImageView.image = [UIImage imageNamed:[imagesArray objectAtIndex:count]];
}
#end

Answer 1

try this....
add images into your project and store those images names into an NSArray
for ex.
//declare imagesArray as instance variable
NSArray *imagesArray = #[#"image1.png",#"image2.png",#"image3.png",#"image4.png"];
and in the button action method
- (IBAction)buttonPressed
{
count ++;
if(count == imagesArray.count)
{
count = 0;
}
yourImageView.image = [UIImage imageNamed:[imagesArray objectAtIndex:count]];
}
