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.
