-(void)buttonPressedUIButton *)button
{
[self.view setBackgroundColor:[UIColor redColor]];
}

//this code assumes you are using a view controller

[Senly]

ok i wanted to do a changing background app i did this in the MyvIew.h file

@interface MyView : UIView
{
IBOutlet UIView *color;
}
-(IBAction)Lightid)sender;
-(IBAction)Darkid)sender;
@end

and this in the MyViem.m file

@implementation MyView
-(IBAction)lumiereid)sender
{
[self.view setBackgroundColor:[UIColor whiteColor]];
}
-(IBAction)ombreid)sender
{
[self.view setBackgroundColor:[UIColor blackColor]];
}
@end


like you told me, i made 2buttons and 1 View and i connect them but wen i build it says

error:request for member 'view'in something not a structure or union ...

I have found too many problems with the interface builder and just code things manually.

simpleAppDelegate.h

//
//  simpleAppDelegate.h

#import <UIKit/UIKit.h>

@class MyView;

@interface simpleAppDelegate : NSObject {
	IBOutlet UIWindow *window;
	IBOutlet MyView *contentView;
}

@property (nonatomic, retain) UIWindow *window;
@property (nonatomic, retain) MyView *contentView;

@end

simpleAppDelegate.m

//
//  simpleAppDelegate.m

#import "simpleAppDelegate.h"
#import "MyView.h"

@implementation simpleAppDelegate

@synthesize window;
@synthesize contentView;


- (void)applicationDidFinishLaunching:(UIApplication *)application {	
     window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
     contentView = [[MyView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
     [window addSubview:contentView];


	[window makeKeyAndVisible];
}


- (void)dealloc {
	[contentView release];
	[window release];
	[super dealloc];
}

@end

MyView.h

//
//  MyView.h

#import <UIKit/UIKit.h>

@interface MyView : UIView {
UIButton *blackButton;
UIButton *whiteButton;
}

@end

MyView.m

//
//  MyView.m


#import "MyView.h"


@implementation MyView


- (id)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
        // Initialization code.
	[self setBackgroundColor:[UIColor cyanColor]];
		

		
    //add a Black button
    blackButton = [[UIButton buttonWithType:UIButtonTypeGlass] retain];
    [blackButton setFrame:CGRectMake((self.bounds.size.width - 100.0) / 2.0,100.0, 100.0, 40.0)];
    [blackButton setTitle:@"BLACK" forStates:UIControlStateNormal];
	[blackButton setBackgroundColor:[UIColor clearColor]];
    [blackButton setTintColor:[UIColor blackColor]];
	[blackButton addTarget:self action: @selector(turnBlack:) forControlEvents:UIControlEventTouchUpInside];
	[self addSubview:blackButton];
	
	 //add a White button
    whiteButton = [[UIButton buttonWithType:UIButtonTypeGlass] retain];
    [whiteButton setFrame:CGRectMake((self.bounds.size.width - 100.0) / 2.0,200.0, 100.0, 40.0)];
    [whiteButton setTitle:@"WHITE" forStates:UIControlStateNormal];
	[whiteButton setBackgroundColor:[UIColor clearColor]];
    [whiteButton setTintColor:[UIColor whiteColor]];
	[whiteButton addTarget:self action: @selector(turnWhite:) forControlEvents:UIControlEventTouchUpInside];
	[self addSubview:whiteButton];

    }
    return self;
}

-(void) turnBlack:(id)sender
{
[self setBackgroundColor: [UIColor blackColor]];
}

-(void) turnWhite:(id)sender
{
[self setBackgroundColor: [UIColor whiteColor]];
}





- (void)drawRect:(CGRect)rect {
    // Drawing code.
}


- (void)dealloc {
  [blackButton release];
  [whiteButton release];
  [super dealloc];
}

@end
