Switch Button not working in Cocoa-Touch

Question

I am new to Objective-C and Cocoa-Touch development. I have an ON/OFF Switch on a view that is supposed to disable/enable hide/show another button on the same view, but for some reason it doesn't work sometimes, this is the behavior:

1st click: Switch to OFF, Other Button hidden => OK
2nd click: Switch to ON, Nothing happens => WRONG
3rd click: Switch to OFF, Other button SHOWN => WRONG
4th click: Switch to ON, Nothing happens => WRONG
5th click: Switch to OFF, Other Button hidden => OK

This is the code:

MainViewController.h :

@interface MainViewController : UIViewController <FlipsideViewControllerDelegate> {
IBOutlet UIButton *resetButton;
}

@property (retain) UIButton *resetButton;

MainViewController.m :

@synthesize resetButton;

- (IBAction)switchTimer { 
resetButton.enabled = !resetButton.enabled;
resetButton.hidden = !resetButton.hidden;
}

What am I doing wrong? I appreciate your help.

Answer 1

Well as long as your UISwitch has the Value Changed action targeted at your MainViewController, then it should work. I would suggest the following however.

// Add the (id)sender parameter to obtain the UISwitch (less coupled approach)
-(IBAction)onSwitchChange:(id)sender
{
    // If a control is hidden, disabling it is not required
    resetButton.hidden = ![sender on];
}

Thanks for the help! actually the problem was I had used the "Touch Up Inside" action, I changed to the "Value Changed" event. and it worked!

Thanks a lot!
