UIButton properties

This should be really simple but I can't figure it out. I have a button and an on/off switch. When the witch is set to on I want the button to be visible and when it is set to off I want the button to be hidden. The switch is called solutionSlider and the button is called button. Here's my code:

Code:

if (solutionSlider.on = FALSE) 
		button.hidden = TRUE;
	else if (solutionSlider.on =TRUE) 
		button.hidden = FALSE;

The switch doesn't seem to have any effect on the button. Any ideas?

In your if statement you are setting the value of solutionSlider.on. You are using the assignment operator (=) not the comparison operator (==).

I do that from time to time.

An easier way would be to do this single statement:

button.hidden = !solutionSlider.on;

Thanks that got it working.

What I'm really trying to do is make is a button in a different view hidden. The switch is in settingsView and the button is in rulesView. Here is my .h files:

Code:

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>


@class RulesView;

@interface SettingsView : UIView {
	
	IBOutlet UISwitch *solutionSlider;
	IBOutlet UISwitch *soundSlider;
	IBOutlet UISwitch *shakeSlider;
	
}

-(IBAction)solutionSlider:(id)sender;
-(IBAction)soundSlider:(id)sender;
-(IBAction)shakeSlider:(id)sender;

@end

Code:

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>

@interface RulesView : UIView {
	IBOutlet UIButton *showAnswer;
}

//this is the method/action which contains the code to load the answer site
-(IBAction)showAnswer:(id)sender;

@end

The button I want the switch to hide is called showAnswer.

Could you tell me what I'm doing wrong. I have a rough idea (settingsView doesn't know about showAnswer button because it's in a different view) and I thought all I had to do was add the @class part) but can;t get it to work. Oh I also added

Code:

#import "RulesView.h"

to my settingsView.m file
