I found the code below in the Apple documentation and added it to my viewDidLoad method but the slider doesn't appear when I run the code.
viewDidLoad
CGRect frame = CGRectMake(0.0, 0.0, 200.0, 10.0); UISlider *slider = [[UISlider alloc] initWithFrame:frame]; [slider addTarget:self action:@selector(sliderAction:) forControlEvents:UIControlEventValueChanged]; [slider setBackgroundColor:[UIColor clearColor]]; slider.minimumValue = 0.0; slider.maximumValue = 50.0; slider.continuous = YES; slider.value = 25.0;
You need to add the slider into your view hierarchy. Add [self.view addSubview:slider]; and it should work.
[self.view addSubview:slider];
