I've been toying with the idea of allowing the slider to continue incrementing or decrementing the value until the user releases the touch from the slider. This functionality could be toggled with a boolean. What does the community think? Would you guys like to see this?

Hi: thanks for the great slider. I am using it in my app. I have one slight issue. I cant seem to change the code to move it to the top of my app. No matter which CGrect I change the slider is always in the center vertically and horizontally. Any help would be greatly appreciated.

I called this in my override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell function:

let QuantitySlider = SnappingSlider(frame: CGRectMake(0.0, 0.0, 10.0, 10.0), title: "Quantity")
        QuantitySlider.translatesAutoresizingMaskIntoConstraints = false
        cell.QuantitySliderView.addSubview(QuantitySlider)
        QuantitySlider.delegate = self

        QuantitySlider.frame = CGRectMake(0.0, 0.0, cell.QuantitySliderView.bounds.size.width * 0.5, 50.0)
        QuantitySlider.center = CGPointMake(cell.QuantitySliderView.bounds.size.width * 0.5, cell.QuantitySliderView.bounds.size.height * 0.5)

However, the slider doesn't seem to come in the right place. I also added

print(QuantitySlider.bounds)
print(cell.QuantitySliderView.bounds) 

in my method, and the result is (0.0, 0.0, 258.0, 50.0) (0.0, 0.0, 516.0, 68.0)

I try to fix the screen in my storyboard in to 5.5 inch iPhone size, and the result is around (0.0, 0.0, 167.0, 50.0) (0.0, 0.0, 334.0, 68.0)

I think this is where the problem is. By the way, my QuantitySliderView has constraints that keep it in the center of the cell, so it is not the case that my QuantitySliderView has problem. Please respond, thank you!

When trying to install I get this issue:

Thanks for your beautiful slider, I'm using it for my Swift class assignment.

Here's my question:

When I tried to build something just like your demo GIF, where the slider controls the text of the UILabel, I found it quite difficult to make one. Since I had to use auto layout for adaptivity, I had a UIView to contain the slider. I wrote some lines of codes based on your given 'Usage' example, and I found it unable to control the text of the UILabel. When I tried to move the slider, it just reset itself to the initiate state while not change a thing. however, it was not completely not working since it run smoothly if I just wrap some print command in the function.

P.S., I found that there is some unexpected part of the slider (color is the same as the middle of the slider) on the right padding of the UIView, and I drew CGRect to cover it up. Hope there is a better way to avoid this.

Here's my code of the ViewController.

import UIKit
import SnappingSlider

class ViewController: UIViewController, SnappingSliderDelegate {

    @IBOutlet weak var sliderView: SliderView!
    @IBOutlet weak var hoursLabel: UILabel!

    override func viewDidLayoutSubviews() {
        let sliderLength = sliderView.frame.size.width
        let sliderWidth = sliderView.frame.size.height
        let slider = SnappingSlider(frame: CGRectMake(0.0, 0.0, sliderLength, sliderWidth), title: "Working Time")
        slider.delegate = self
        let sliderMask = UIView(frame: CGRectMake(sliderLength,0.0,40,50))          // sliderMask is used to cover the unexpected part
        sliderMask.backgroundColor=UIColor.whiteColor()
        sliderView.addSubview(slider)
        sliderView.addSubview(sliderMask)
        hoursLabel.text = "3"
    }

    func hoursChange(symbol: String) {
        let a = Int(hoursLabel.text!)!
        let b = 1
        if symbol == "+" {
            hoursLabel.text = "\(a+b)"
//            print("\(a+b)")                           // run smoothly if the previous line is commented while this line is not commented
        } else if symbol == "-" {
            hoursLabel.text = "\(a-b)"
//            print("\(a-b)")                           // run smoothly if the previous line is commented while this line is not commented
        }
    }

    func snappingSliderDidIncrementValue(snapSwitch: SnappingSlider) {
        hoursChange("+")
    }

    func snappingSliderDidDecrementValue(snapSwitch: SnappingSlider) {
        hoursChange("-")
    }
}

Thanks for your help!

Hey, I really like this control! One thing I could see being useful, is making the decrease/increase labels into buttons instead. To allow for precision.

hello how can add 3 smappinslider and func snappingSliderDidIncrementValue(snapSwitch: SnappingSlider) ,func snappingSliderDidDecrementValue(snapSwitch: SnappingSlider) ??

Hey!

So I took a quick look through and saw some opportunities to be more idiomatic with Swift. The big ones are:

• Makes things public for use inside Frameworks.
• Removes a bunch of self.
• Removes unnecessary explicit type declarations on properties.
• Removes setting variable to default, private value in initializer (uses defaults on declarations instead).
• Uses didSet to inject side-effects.

I noticed you're setting a lot of frames, then centers. This is usually not necessary – setting frame is actually shorthand for setting the bounds.size and the centre. If you'd like to continue doing so, that's cool. There're methods like CGRectGetMidX() that can be used instead of bounds.size.width * 0.5, too.

hello when i insert SnappingSliderDelegate error Use of undeclared type 'SnappingSliderDelegate' and when that import SnappingSlider error : No such module 'SnappingSlider'
