How to Change the UISlider to Vertical?

Question

I am customizing an UISlider for my app. I want the slider to be in vertical orientation, but the default UISlider is in horizontal orientation. I couldn't find how to change a UISlider's orientation.

How can I make a vertical slider in XCode?

Answer 1

By default, a UISlider is horizontal (--). If you wish to make it vertical (|) then you must do this programmatically, probably with a CGAffineTransform. For example, you can add this snippet to viewDidLoad or wherever you deem appropriate:

CGAffineTransform trans = CGAffineTransformMakeRotation(M_PI_2); slider.transform = trans; 

Answer 2

In case you are using auto layouts:

In your viewDidLoad, try:

UIView *superView = self.sizeSlider.superview; [self.sizeSlider removeFromSuperview]; [self.sizeSlider removeConstraints:self.view.constraints]; self.sizeSlider.translatesAutoresizingMaskIntoConstraints = YES; self.sizeSlider.transform = CGAffineTransformMakeRotation(M_PI_2); [superView addSubview:self.sizeSlider]; 

It does not work with constraints, so the trick is to remove the constraints for your uislider. You might have to resize it manually by setting its frame property.
