Change the custom button by an other when the user click on it

I try to realize that, when the user click on a button (custom one), it will be changed by another button, to do so, i use the selected property :

What i notice that the image of the button is changed while the user keep pressing th开发者_JAVA百科e button, if he releases the button, it returns to his old form, what i need is it still changed sine the user select the button.

There is only one line of code.

[yourButton setBackgroundImage:[UIImage imageNamed:@"select-button.png"] forState:UIControlStateHighlighted];

This is best done programmatically, rather than in Interface Builder. Set up an action for your button such that when it is clicked, the button image changes:

- (IBAction)buttonTapped:(id)sender
{
    UIButton *theButton = (UIButton *)sender;
    if ([theButton currentImage] == self.imageOne) {
        [theButton setImage:self.imageTwo forState:UIControlStateNormal];
    }
    else {
        [theButton setImage:self.imageOne forState:UIControlStateNormal];
    }

    // (remaining action code)...
}

I think best way is Use two button in same frame ,When user click Button1,hide button1 and show button2.if user click button2,hide button2 and show button1
