how can i change button background image when it is clicked in iphone?

Question

how can i change background image of UIButton when it is clicked and it should remain as it is until another button is clicked.

Solution 1

[myButton setImage:[UIImage imageNamed:@"btn_normal.png"] forState:UIControlStateNormal];
    [myButton setImage:[UIImage imageNamed:@"btn_highlighted.png"] forState:UIControlStateHighlighted];
    [myButton setImage:[UIImage imageNamed:@"btn_highlighted.png"] forState:UIControlStateSelected];
    myButton.showsTouchWhenHighlighted = YES;

Fourth line myButton.showsTouchWhenHighlighted = YES; will do the trick. Please try.

Solution 2

Working Code :

// 1) Give tag to all needed button

// 2) check which button is selected by "sender tag"

// 3) set all other buttons to not selected

-(IBAction) buttonPressed:(id)sender
 { 
      if ([sender isSelected]) 
      {  
          [sender setImage:unselectedImage forState:UIControlStateNormal];  
          [sender setSelected:NO];  
      }
      else 
      {     
          [sender setImage:selectedImage forState:UIControlStateSelected]; 
          [sender setSelected:YES]; 
      }
 }

you need to review UIButtonClass reference to get solutions.

Solution 4

You will need to set the image every time user taps any button on your view. So when user taps your button, set its image to something that you want(lets assume thats its darker) and the rest of the buttons to normal image(lets assume lighter). Then when user taps other button, repeat the process.

    [yourButton setImage:[UIImage imageNamed:youImage] forState:UIControlStateNormal];

Hope this helps.

it changes the image when it pressed but after then it comes back to its orginal(old) image...... i want to keep the new image and dont want to allow user to touch that button again (disable) with new image

[Vaibhav Tekam]

can you try to use yourButton.enabled property to use.

i have tried that but its changes the background image color as setting enable or disable has its own colors
