How can I create and display a UISlider programmatically in iOS?

Solution
You need to add the slider into your view hierarchy. Add `[self.view addSubview:slider];` and it should work.
Problem
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. ``` 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; ```
