How can I set a value on click ?

[nahouto]

Hi,

Thank you for your easy to use pod !

I would like to allow the user to set a rating value when clicking on a star. How can I do that ?

Thanks.

Hello,

Can you describe in more detail what do you have in mind? You want to show some popup when one of the stars is tapped?

Hello, Actually, the user can select a rate by "sliding" to the right (in RatingView.swift, you in fact commented "rating when user touches begin/move/end") I would like to allow him to select a rate just by tapping a star.

Ok, I made it by adding a tap recognizer in customInit :

// add tap recognizer
let gestureRecognizer = UITapGestureRecognizer(target: self, action: "handleTap:")
self.addGestureRecognizer(gestureRecognizer)

and adding the following function :

/**
 Compute and adjust rating when user taps
 */
func handleTap(gestureRecognizer: UIGestureRecognizer) {
    let touchLocation = gestureRecognizer.locationInView(self)

    for var i = starCount - 1; i >= 0; i-- {
        let imageView = stars[i]

        let x = touchLocation.x;

        if x >= imageView.center.x {
            rating = Float(i) + 1
            return
        } else if x >= CGRectGetMinX(imageView.frame) && halfStarsAllowed {
            rating = Float(i) + 0.5
            return
        }
    }

    rating = 0
}
