    copied!<p>My UIView (<strong>ClassA</strong>) has a button that when pressed shows another UIView (<strong>ColorClass</strong>) with 3 buttons that allows a user to select a color. The color that is selected is passed back to <strong>ClassA</strong> so that it can be worked with. It is also passed to a <em>Storage</em> (a singleton) class for saving the selected color. </p> <p>This works great, but now, I need a second unrelated class <strong>ClassB</strong>, to have same functionality. But when I call the same method I normally call in <strong>ClassA</strong> from inside <strong>ClassB</strong>, <strong>ClassA</strong> is the one that is updated. </p> <p>How can I make <strong>ColorClass</strong> more agnostic to the calling class? I am still learning so if someone could help point me in the right direction that would be great.</p> <p><strong>ClassA</strong></p> <pre><code>- (void) showColorPicker{ CGRect colorPickerFrame = CGRectMake(150, 100, 237, 215); colorPicker= [[ColorClass alloc] initWithFrame:colorPickerFrame]; colorPicker.vc = self; [self.view insertSubview:colorPicker aboveSubview:self.view]; } - (void) setTheButtonColor : (int) c { Sufficient to say this just changes the buttons background color selected from a list of colors } </code></pre> <p><strong>ColorClass</strong> </p> <p>When a selected color is pressed, I call this method that messages ClassA with the color.</p> <pre><code>- (void) buttonPressed : (id) sender { [self.vc setButtonColor:[sender tag]]; [myStorage setButtonColor:[sender tag]]; } </code></pre> <p><img src="https://i.stack.imgur.com/LheLp.png" alt="Layout"></p>
