Question

I have a UIImageview in my application and I was wondering how I can show an image in it pragmatically and change it whenever I want to! I think my major problem is exactly WHERE to put it! If you could show me what code and where that would be very usefull! thanks!

EDIT: Also if you can pragmatically change the background into an image or even a color! thanks! either or will work!

EDIT2: here is my code, i dont know where to put those because they always give me an error!

MainView.h

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>

@interface MainView : UIView {
    //static int r;
    int r;
    IBOutlet UIButton *myButton;
    IBOutlet UILabel *myTextLabel;
    IBOutlet UILabel *myTextLabel2;
    IBOutlet UIImageView *myImage;

}

@property (nonatomic, retain) UIButton *myButton;
@property (nonatomic, retain) UILabel *myTextLabel;
@property (nonatomic, retain) UILabel *myTextLabel2;
@property (nonatomic, retain) UIImageView *myImage;



- (IBAction)buttonclick;

//+(void) initialize;

@end

and the

MainView.m

#import "MainView.h"
#include <stdlib.h>
#include <libc.h>


@implementation MainView

@synthesize myButton, myTextLabel, myTextLabel2, myImage;   


- (IBAction)buttonclick {

    r++;

    if(r == 1) {

        self.myTextLabel.text = @"word";
        self.myTextLabel2.text = @"def.";

    }else if(r == 2) {

        self.myTextLabel.text = @"word2";
        self.myTextLabel2.text = @"def2 ";  
    }

}

@end

To change the image itself, you can write:

UIImage* myNewImage = ...;
myImageView.image = myNewImage;

To change the background of your UIImageView, you can write:

myImageView.backgroundColor = [UIColor redColor];

… or whatever other UIColor you would like, including another image used as a pattern.
