Question

I have implemented a custom class of UISlider so the touchable areas are larger

Everything is working great except now I want to change the initial values depending on other factors in the app.

The only code I have gets the slider’s ID from (sender)

I need to address the slider like so…

slider.value = 25.0;

But the only code I have is

-(IBAction) slider1Changed:(id) sender{
    UISlider *slider = (UISlider *) sender;
    int progressAsInt =(int)(slider.value);
    NSLog(@"Slider is %@",slider);
    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    [prefs setInteger:progressAsInt forKey:@"SharedSkilledWorkforce"];
}

In the xib @property (nonatomic, retain) UISlider *slider1; doesn’t show up as a conncetion

How do I address the custom UISlider?

Answer 1

Have you tried adding IBOutlet to your slider1 property?

This:

@property (nonatomic, retain) UISlider *slider1; 

Needs to be:

@property (nonatomic, retain) IBOutlet UISlider *slider1; 

in order to show up in IB. IBOutlet is a hint to the designer similar to IBAction.
