button image change using predefined method

In my app am using UIScrollView. I added buttons to UIScrollView. For each button i assigned image using

- (void)setImage:(UIImage *)image forState:(UIControlState)state;

and actions.

forState i used UIControlStateNormal in viewDidLoad.

And when we click on button image has to change. For this i used same method but forState value changed to UIControlStateSelected in ViewDidLoad.

But button image is not changing. any one can help or suggest

You've to use like this

In ViewDidLoad Set images for normal and selected state

-(void)ViewDidLaod

[myButton setImage:[UIImage imageNamed:@"barbutton.png"] forState:UIControlStateNormal];

[myButton setImage:[UIImage imageNamed:@"barbutton1.png"] forState:UIControlStateSelected];

To perform selection image change can be done below code

 -(void)buttonclick

[myButton setSelected:YES];

or

[myButton setSelected:NO];

Use this line of code I think this will be helpful for you.

-(void)viewDidLoad
 {
    UIButton *myButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
    [myButton setFrame:CGRectMake(0,3,70,32)];
    [myButton setImage:[UIImage imageNamed:@"barbutton.png"] forState:UIControlStateNormal];
    [myButton addTarget:self action:@selector(compete) forControlEvents:UIControlEventTouchUpInside];
 }
 -(void)compete
 {
    [myButton setImage:[UIImage imageNamed:@"barbutton1.png"] forState:UIControlStateNormal];
 }

[button setImage:[UIImage imageNamed:@"button_highlighed.png"] forState:UIControlStateHighlighted];
