iOS UIButton background images

[DennisBlah]

Hi all,

I'm working on my 'footer' with dynamic buttons.
These buttons don't get an title, only an image. For both states, normal and selected.

However when I programaticly set the button state to selected, there is this anoying small blue square at the top left of my button.

How do I get rid of this ?

Could you provide both a screenshot of the problem and the code you've used to set up the buttons?

Hi Ubuntu,

right now, they are setup in storyboard. In future I will add them programaticly.
Dont mind the calendar button it's not the correct one yet xD

At the top left of the Home button you see a blue square.
(This is in selected state)

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    //Bunch of  code here to setup seque, check for viewcontroller etc etc.
    int counter = 0;
    for (UIButton *aButton in self.buttons) {
//Setup buttons
        [aButton setBackgroundImage: [UIImage imageNamed: [buttonImages objectAtIndex: counter]] forState: UIControlStateNormal];
        [aButton setBackgroundImage: [UIImage imageNamed: [buttonImagesActive objectAtIndex: counter]] forState: UIControlStateSelected];
        [aButton setSelected: NO];
        counter++;
    }

//Set current state of pressed button to selected
    UIButton *button = (UIButton *)sender;
    [button setSelected:YES];
    
    
//Bunch of code here, check if my original 'rootViewcontroller's header' must be in or not.
}

}

I can't see anything wrong with that code.

• Are you setting the button's image anywhere? In the storyboard?
• Have you checked the original icon to make sure it's fine?
• What happens if you set the background image in the storyboards?
  

Also you don't need the counter variable. You're using a for-in loop which means you can simply state the following:

[buttonImages objectAtIndex: [self.buttons indexOfObject:aButton]]

Ah lol I didnt thought if that
The normal image is also set in storyboard for now

The thing is where the button is set as selected
Then I get this blue square on the top left corner of the button

I dont know how to set different images for different states in storyboard? :-$

P.s. It are 2 different images. 1 with a brightness of +50 for the selected button

----

Resolved:
In storyboard, I had to set background and tint, under View, to clear color.
That solved the problem.

Thanks for the help!
