Question

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

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];
 }
