How to put UISlider vertical?

Question

I want to put UISlider in vertically. I have no idea about this, so please help me for this.

Answer 1

You have to do this programaticaly. Assuming your UISlider is bound to a variable called slider, add this code in your viewDidLoad method in ViewController.m:

- (void)viewDidLoad {

    [super viewDidLoad];

    CGAffineTransform trans = CGAffineTransformMakeRotation(M_PI * 0.5);
    slider.transform = trans;
}

Let me know if you need any more help on this..

Answer 2

As of Xcode 4.2, you can sort of do the same in Interface Builder.

• Create a slider
• Show the "Identity Inspector"
• Add a "User Defined Runtime Attribute"
• Set the key path to "layer.transform.rotation.z", the type as "String" ("Number" won't allow floating point values) (possible since Xcode 5) and the value to "-1.570795" (-π/2).

Unfortunately, it will still appear as horizontal in Interface Builder.

But you can position the center and don't need to create a custom class, so it might be useful enough in some cases. The effect is the same as ravinsp's code.
