Question

Is there anyone who can teach me how to show an UISegmentedControl object in vertical direction, instead of in horizontal direction?

Answer 1

+1 for Ben’s answer, although rotating the segmented control also rotates the text inside. Never fear! We just have to rotate the inside labels, like so:

    NSArray *arr = [segmentedControl subviews];
    for (int i = 0; i < [arr count]; i++) {
    UIView *v = (UIView*) [arr objectAtIndex:i];
    NSArray *subarr = [v subviews];
        for (int j = 0; j < [subarr count]; j++) {
            if ([[subarr objectAtIndex:j] isKindOfClass:[UILabel class]]) {
                UILabel *l = (UILabel*) [subarr objectAtIndex:j];
                l.transform = CGAffineTransformMakeRotation(- M_PI / 2.0); //do the reverse of what Ben did
            }
        }
    }

Swift 2 version:

for view in segmentedControl.subviews {
    for subview in view.subviews {
        if subview.isKindOfClass(UILabel) {
            subview.transform = CGAffineTransformMakeRotation(CGFloat(-M_PI / 2.0))
        }
    }
}
