I'm trying to run the example source code in xocde version 9.4.1 but I get errors like this " 'Attribute' is not a member type of 'NSLayoutConstraint' , 'Relation' is not a member type of 'NSLayoutConstraint' " in it's miniLayout class.

I am facing an issue where the slider track gets aligned to the top of the UIView. Has anyone faced such issue? I am attaching the screenshots of the MultiSliders along with UIDebugger screenshot. TIA.

The UIView is vertically centered to UIImageView with horizontal spacing.

This is the screenshot of UIDebugger.

I needed to specifically listen for the .touchDown event and when I added the below code it didn't work.

lazy var slider: MultiSlider = {
    let s = MultiSlider()
    // ...
    s.addTarget(self, action: #selector(sliderBeganTracking(_:)), for: .touchDown)
    return s
}()

@objc func sliderBeganTracking(_ slider: MultiSlider) {
    print("Finger initial tap: \(slider.draggedThumbIndex)")
    // do something **only** on initial touch
}

To get it to work, I had to go into your MultiSlider+Drag file and add the sendActions(for: .touchDown) event to your .began gesture

@objc open func didDrag(_ panGesture: UIPanGestureRecognizer) {
        switch panGesture.state {
        case .began:
            // ...
            sendActions(for: .touchDown)

Can you please add the sendActions(for: .touchDown) event?

ageSlider.distanceBetweenThumbs = 4 causes my app to crash every time. I do not understand why or what to do to get a minimum distance of 4 between my two sliders. Crash report says the following:

There is a demand to use custom text for valueLabel, such as below.

This revision enables to set custom text by passing string array. multiSlider.valueLabelTexts = ["value1", "value2"]

Below are the points that can be considered

• In this implementation, when the size of valueLabelTexts differs from the size of value, original text (which is the value) is displayed.
• It might be better to rename valueLabel to a name such as thumbLabel, since the label will not always be a value.

Everything with your library seems to work fine except I can't get the right side thumbnail to show:

var leftThumbValue: CGFloat = 0 // this always gets set as I slide the slider
var rightThumbValue: CGFloat = 0 // this NEVER gets set as I slide the slider

lazy var slider: MultiSlider = {
        let s = MultiSlider()
        s.translatesAutoresizingMaskIntoConstraints = false

        s.orientation = .horizontal
        s.minimumValue = 0
        
        s.keepsDistanceBetweenThumbs = false
        
        s.outerTrackColor = .white
        s.tintColor = .red
        s.thumbTintColor = .orange
        
        s.trackWidth = 10
        s.showsThumbImageShadow = false
        
        s.valueLabelTextForThumb = { [weak self](thumbIndex, thumbValue) in
            
            if thumbIndex == 0 {
                self?.leftThumbValue = thumbValue
            }
            
            if thumbIndex == 1 {
                self?.rightThumbValue = thumbValue
            }
            
            return ["Parasol", "Umbrella"][thumbIndex] + " \(thumbValue)"
        }
        
        s.addTarget(self, action: #selector(sliderBeganTracking(_:)), for: .touchDown) // I adde the .touchDown event to  MultiSlider+Drag
        s.addTarget(self, action: #selector(sliderValueChanged(_:)), for: .valueChanged)
        s.addTarget(self, action: #selector(sliderEndedTracking(_:)), for: [.touchUpInside, .touchUpOutside, .touchCancel])
        return s
}()

override func viewDidLoad() {
        super.viewDidLoad()

        // set anchors for slider 
        // set up AVPlayer with AVAsset

       let videoDurationTime: Float64 = CMTimeGetSeconds(asset.duration)
       slider.maximumValue = CGFloat(videoDurationTime)

       setTimeObserverToken()
}

func setTimeObserverToken() {

    timeObserverToken = player?.addPeriodicTimeObserver(forInterval: interval, queue: DispatchQueue.main, using: {
            [weak self] (progressTime) in

            let seconds = CMTimeGetSeconds(progressTime)

            self?.trimSlider.value = [CGFloat(seconds)]
    }
}

What am I doing wrong?

I also tried to add icons in the slider closure but not only is the right thumbnail not showing, the left thumbnail is just a circle, it doesn't take the form of the beeIcon. Both icons are in the Assets folder and spelled correctly

lazy var slider: MultiSlider = {
    let s = MultiSlider()
    // ... all the other code from above

    s.minimumImage = UIImage(systemName: "beeIcon")
    s.maximumImage = UIImage(systemName: "antIcon")

    return s
}()

Description: Using your swiftui slider for my project and was wondering if you'd be able to add the ability to choose the font for the labels.

Wondering if it would be possible to add the ability to change the size of the thumbs (the circles).

Thank you!

Description of the problem: With a 2 thumb slider, the 2nd thumb can go below the minimum value.

Minimal project that reproduces the problem (so I'll be able to figure out how to fix it): slider.minimumValue = 18 slider.maximumValue = 100 slider.value = [18, 100] sliderOrientation = .horizontal slider.keepsDistanceBetweenThumbs = false slider.widthAnchor.constraint(equalToConstant: 200)

// Drag the 2nd thumb all the way left... print("slider.value[1]") // prints 17.920077972709553

Description of the problem: [description]

I have added a UIImage to each thumb in the MultiSlider but when I drag either the left thumb to the most minimum value or the right thumb to the most maximum value, it leaves a gap. So I thought if I increase the image size then I would solve that issue, what actually happened is the gap became bigger on both sides

Minimal project that reproduces the problem (so I'll be able to figure out how to fix it): [github repo or a zipped project]

This helps reacting on the “final” value change rather than every value change while dragging the thumb.

Example: track live changes to the slider in a UILabel via .valueChanged while waiting to apply the value until the user finished dragging via .touchDragExit.

Additions cause SwiftLint to complain: Cyclomatic Complexity Violation: Function should have complexity 10 or less: currently complexity equals 12 (cyclomatic_complexity) …so, raise the limit? :)

UPDATE: Now sending .touchUpInside

Hello, I've used Multi slider in my project. But now I what to restrict the dragging of sliders for a particular user.

So what I want is, I want to check a condition before starting dragging.

Is there any way to do such thing?

Thanks in advance

Description:

Support for multiple snap step sizes on one slider, e.g 2 and 4 The x value represents a size of 2. The y value represents a size of 4.

Here, snap step size should be 2. [x] - [x] - [x] - [x] - [ ] - [y] - [ ] - [y]

Here, snap step size should be 4. Allowing the first thumb to move to the next y ignoring the blank node which would be a 2 step. [x] - [x] - [x] - [x] - [ ] - [y] - [ ] - [y]

At the moment, there's only support for one step size and we were wondering if it would be possible to snap onto bigger gaps.

Problems we encountered when trying to implement this myself:

We've added an if statement to change the snap step size to 2 or 4 depending on where the second thumb is. This has caused the following problems.

1. When we try to move the first thumb onto the next y node, it snaps in between because it's making a size 2 step. [x] - [x] - [x] - [x] - [ ] - [y] - [ ] - [y] [x] - [x] - [x] - [x] - [!] - [y] - [ ] - [y]

2. When moving the last y node to the previous y, the x moves as well.

[x] - [x] - [x] - [x] - [y] - [y] [x] - [x] - [x] - [x] - [y] - [y]

We wanted to check if there is a more efficient way of doing this as we've spent lots of time trying to achieve the desired behaviour and creating a new Slider from UIControl proves to be somehow tricky for our team.

Thank you, Christian

Description: You currently do not have support for Carthage.

Problems I encountered when trying to implement this myself: I'm working in a project where we are trying to remove the cocoapods, and we've moved all our libs to Carthage.

We would like to use your lib without the need to use cocoapods.
