copied!<p>I've been searching all over the net for an answer to this one! Hoping one of you can help me.</p> <p>So far I have a button that produces a random nr between 1 and 6 in a label.</p> <blockquote> <blockquote> <p>Then I want a picture to appear depending on what nr is in the label.</p> </blockquote> </blockquote> <p>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? </p> <p>Sorry for bad formating.</p> <p>Here is the .h file:</p> <pre><code>#import <UIKit/UIKit.h> @interface xxxViewController : UIViewController { IBOutlet UILabel *label; int randomNumber; } -(IBAction)randomize; @end </code></pre> <p>...and here is the .m file:</p> <pre><code>#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 </code></pre>
