Autolayout not working

[yawboafo]

Applying constrains programatically to this seems not to work

WidthAnchor and HeightAnchor somehow does not affect the view , you will have to set the view width and height using the Frame .

I face the same autolayout problem. Could it be solved?.
the strange thing is that in the example project, if they work. @yawboafo @korantengNanaYaw

I added an example for applying constraints programmatically. It's working without the problems mentioned. Please check the code in file ViewController.swift, or bellow:

// Example for applying constraints programmatically
func applyNewConstraints() {
   // ......

   // Add new constraints programmatically
   self.stepIndicatorView.widthAnchor.constraint(equalToConstant: 263.0).isActive = true
   self.stepIndicatorView.heightAnchor.constraint(equalToConstant: 80.0).isActive = true
   self.stepIndicatorView.centerXAnchor.constraint(equalTo: self.view.centerXAnchor).isActive = true
   self.stepIndicatorView.topAnchor.constraint(equalTo: self.view.layoutMarginsGuide.topAnchor, constant:30.0).isActive = true
    
   self.scrollView.topAnchor.constraint(equalTo: self.stepIndicatorView.bottomAnchor, constant: 8.0).isActive = true
}

The running effect with constraints added programmatically:

Please let know if there is something I missed. @yawboafo,@korantengNanaYaw,@derlysbenito

Try creating the step Indicator programatically , remove and delete the reference from story board., to reproduce the issue i'm facing

lazy var stepIndicatorView: StepIndicatorView = {
		let view = StepIndicatorView()
		view.numberOfSteps  = 3
		view.circleStrokeWidth = 1.5
		view.circleRadius = 14
		view.lineMargin = 4.0
		view.lineStrokeWidth = 2.0
		view.displayNumbers = true
		view.direction = .leftToRight
		view.translatesAutoresizingMaskIntoConstraints = false
		return view
	}()

The fix i used was that i had to define

 view.frame.size.width = 300
 view.frame.size.height = 100`

i still could not set widthAnchor without defining the frame size

@yawboafo , thanks for the helpful details. The bug is now FIXED with the new version 1.0.8. Please update the lib with pod or source code.

Excellent, I just updated my library to version 1.0.8, and the autolayout works perfectly! thanks for the support @chenyun122 . This library seems great to me.

Thanks it works now !
