UIButton Selected Status Change Image

Question

I know this should be very simple, but since I really searched here and on Google without making my code work, I will ask. Yes, I checked related questions and they do not work ...

I just want to change the button image when clicked.

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 also tried to do this in the attribute inspector, but none of them work!

Note that I am not looking for how to make the selected state, but the selected one.

Answer 1

I believe that you need to set the button state selected when the button is pressed. Maybe something like this:

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

Answer 2

You need to set an image for each state from the interface builder, and you do not need to add code if you want:

Select State Config - Default , and then select an image

Select State Config - Selected , and then select an image.

And now to check each button state:

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

Answer 3

Do you have a method when the button is pressed? If yes, put the following lines here:

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

Answer 4

Why not try setting the default background image to "normal.png";

 [self.mybutton setBackgroundImage:[UIImage imageNamed:@"normal.png"]]; 

And switch to "selected.png" when the button is executed.

 [self.mybutton setBackgroundImage:[UIImage imageNamed:@"selected.png"]]; 

Answer 5

Change any image that you need in the IB constructor in the Status Configuration, and add an action to this button and add this line of code, as indicated in @Aladin.

  @IBAction func btnPressed (_ sender: UIButton) { // If you want to change it for selected state when tapped. sender.isSelected = !sender.isSelected }
