Question

I have a UIImageView *picture

and a UIButton *next

and an

- (IBAction)next {
}

I want to change the image on the view but only if the image equals… for example img1

But using the same button I want to also be able to change the picture if the image = img2 but to a different image (img3)

So far I have this code but it gives me errors:

- (IBAction)next {
    if (picture UIImage = imageNamed:@"img01.jpg") {
    [picture setImage: [UIImage imageNamed:@"img02.jpg"
    }
    if (picture UIImage = imageNamed:@"img02.jpg") {
    [picture setImage: [UIImage imageNamed:@"img03.jpg"
 }
}

Answer 1

I figured it out now all I did was forget to put .jpg on the end of the img%i 😉

- (IBAction)next {
     static int index = 0;  // <-- here
    index++;
    // Set imageCount to as many images as are available
    int imageCount=16;
    if (index<=imageCount) {
        NSString* imageName=[NSString stringWithFormat:@"img%i", index];
        [picture setImage: [UIImage imageNamed: imageName]];
    }
}
