I’ve searched a lot, most people like this code:
- (void)viewDidLoad {
[super viewDidLoad];
CGAffineTransform trans = CGAffineTransformMakeRotation(M_PI * 0.5);
slider.transform = trans;
}
But for me it creates only thumb, why is it so?
sanity check the slider.value after you transform. The slider will disappear when you have improper value set for it.
