Question

I’m trying to make a button which Full Size the UITextView in my demo app. And resize it to its original size after I RE-touch the button again (AKA Exit Full Screen Mode).

I never tried to add more than one Action on 1 UIButton.

-(IBAction)clickButtonFullSize:(id)sender
{
        CGRect r = [[UIScreen mainScreen] bounds];
        [myText setFrame:r];
}

-(IBAction)clickButtonReSize:(id)sender
{
    [myText setFrame:CGRectMake(0,0,200,200)];
}

The first method is working fine when touching the UIButton. But how can I link the second method with the same button to reSize it (exit the full screen)?

Answer 1

You can simply do this by managing tag of your button. No need for two IBActions.

-(IBAction)clickButtonFullSize:(id)sender
{
    UIButton *btn = (UIButton*) sender;

    if (btn.tag == 0) 
    {
        btn.tag = 1;

        CGRect r = [[UIScreen mainScreen] bounds];
        [myText setFrame:r];

    }
    else 
    {
        btn.tag = 0;

        [myText setFrame:CGRectMake(0,0,200,200)];

    }

}
