Swift UIButton : Selected Emoji disappear

I am using 5 UIButton and I'm getting emoji string in this buttons. But the problem is, when I click the button, emoji disappear on the screen. I guess this is highlighted or selected color problem, but I didn't figure out. What should I do for this?

My code :

func buttonSelectedNot(){
    button1.selected = false
    button2.selected = false
    button3.selected = false
    button4.selected = false
    button5.selected = false
}

@IBAction func favoriteButtonAction(sender: UIButton) {

    // Save Data
    buttonSelectedNot()
    sender.selected  = !sender.selected;
    if (sender.selected)
    {
        sender.selected = true
        emojiString = (sender.titleLabel?.text)!
        print(emojiString)

    }
    else
    {
        print("Not Selected");

    }

}

I solved the problem. The problem is, You need to set titlelabel color for the button. If you don't, it's disappear.

Solved code :

func buttonSelectedNot(){
        button1.selected = false
        button2.selected = false
        button3.selected = false
        button4.selected = false
        button5.selected = false
    }

    @IBAction func favoriteButtonAction(sender: UIButton) {

        // Save Data
        buttonSelectedNot()
        sender.selected  = !sender.selected;
        if (sender.selected)
        {
            sender.selected = true
            emojiString = (sender.titleLabel?.text)!

            **//need to set title color for the button.**
            sender.setTitleColor(UIColor.blackColor(), forState: .Selected)
            print(emojiString)

        }
        else
        {
            print("Not Selected");

        }
        sender.selected = true

    }

Hmm, never worked with emojistrings, but your code is a bit weird. When a button is clicked you set all buttons to selected = false then you set the sender.selected = !sender.selected (which means that sender.selected = true, provided that the sender is one of the buttons in buttonsNotSelected()). Then you check if sender is selected and if it is selected you set it to true again and then add the emojistring.

What happens if the sender.selected = true? Well, you will set it to false using buttonsNotSelected() and then you will invert it and set it to true, even though it probably should be false (provided that sender is one of the buttons in said method). Not sure if this is any issue though, but it seems to me like the reason for the emoji to disappear is because .selected is not set correctly.

Try to clean up your code a bit

func buttonSelectedNot(){
    button1.selected = false
    button2.selected = false
    button3.selected = false
    button4.selected = false
    button5.selected = false
}

@IBAction func favoriteButtonAction(sender: UIButton) {

    // Save Data
    sender.selected  = !sender.selected;
    if (sender.selected) {
        emojiString = (sender.titleLabel?.text)!
        print(emojiString)

    } else {
        print("Not Selected");
    }

    // SET ALL BUTTONS, EXCEPT SENDER, TO FALSE

}
