UIButton selected state change image

Question

I know this should be very simple but since I really have looked around here and on google without getting my code to work I will ask. Yes, I have checked related questions and they does not work...

I simply want to change the image of the button when it is pressed.

This is my header file:

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@property (strong, nonatomic) IBOutlet UIButton *myButton;

@end

And my implementation file:

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
[super viewDidLoad];

    [self.myButton setImage:[UIImage imageNamed:@"normal.png"] forState:UIControlStateNormal];
    [self.myButton setImage:[UIImage imageNamed:@"selected.png"] forState:UIControlStateSelected];

}
@end

The button is built and connected in Main.storyBoard and I have also tried to do it in the attributes inspector but neither way worked!

Please note that I am not looking for how to do highlighted state but selected.

Answer 1

You need to set the image for each state from your interface builder and you don't need to add a code if you want :

Select the State Config to Default and then choose an image

Select the State Config to Selected and then choose an image

And now to test each state of the button:

You can do the same for background image just select the parameter "Background"

Answer 2

I believe what you need to do is set the button's state to selected when the button is tapped. Probably something like this:

-(IBAction)buttonTapped:(id)sender {
    if(self.myButton.selected)
        [self.mybytton setSelected:NO];
    else
        [self.mybutton setSelected:YES];
}
