Random number to pick an image Xcode iPhone

Question

I've been searching all over the net for an answer to this one! Hoping one of you can help me.

So far I have a button that produces a random nr between 1 and 6 in a label.

Then I want a picture to appear depending on what nr is in the label.

For example: If the number 1 is generated, I want img1.png to appear in a UIImageView.(?) I'm thinking maybe a if function to pick the picture?

Sorry for bad formating.

Here is the .h file:

#import <UIKit/UIKit.h>

@interface xxxViewController : UIViewController 
{
    IBOutlet  UILabel *label;
    int randomNumber;
}
-(IBAction)randomize;

@end

...and here is the .m file:

#import "xxxViewController.h"
@implementation xxxViewController

-(IBAction)randomize 
{
    int randomNumber = 1+ arc4random() %(6);
    label .text =   [NSString stringWithFormat:@"%d",randomNumber];

}


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    [super viewDidLoad];

    int randomNumber = 1+ arc4random() %(6);
    label .text =   [NSString stringWithFormat:@"%d",randomNumber];

}

- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}


- (void)dealloc {
    [super dealloc];
}

@end

You can use the number to create the file name, for instance [NSString stringWithFormat:@"image%d.png", number];. It's probably a better practice (though not necessary for what you're doing) to create a list of file names, and associate them with numbers in an NSDictionary so you're always dealing with known image names.
