KVSpinnerView

KVSpinnerView is highly customizable progress HUD with a possibility to show messages or progress while some work is being done. KVSpinnerView has several animation types which was written using CAAnimations.

Installation

Cocoa Pods

Using CocoaPods is highly recommended way you should use to add KVSpinnerView to your project

1. Add this line to your Podfile pod 'KVSpinnerView', '~> 1.0.2'

2. Close .xcodeproj -> Open terminal -> Open project directory -> run pod install

3. Import KVSpinnerView where needed (import KVSpinnerView)

Manual installation

1. Download latest code version

2. Copy KVSpinnerView directory into your project

Usage

You can use KVSpinnerView methods while some tasks are being done in background, some big tasks are loading, etc. To show KVSpinnerView on your screen you should use its static methods.

KVSpinnerView.show()
self.doSomeTask().response { (object) in
	DispatchQueue.main.async {
		KVSpinnerView.dismiss()
	}
}

You also can add status message while KVSpinnerView is being shown. Background rectangle of KVSpinning view will automatically expand regarding to message width.

KVSpinnerView.show(saying: "Hello")

Use this method to remove SKSpinnerView after several seconds.

KVSpinnerView.dismiss(after: 5.0)

There is two ways to add KVSpinner view to your screen:

1. Use method KVSpinnerView.show() to add spinner to UIApplication's window. If you use this method then the spinner will be at screen untill you dismiss it.

2. Use method KVSpinnerView.show(on: _) to add the spinner to a view you choose, e.g.:

class ViewController: UIViewController {
	override func viewDidLoad() {
        super.viewDidLoad()
		KVSpinnerView.show(on: self.view)
    }
}

To hanle a progress of current request you need to call 'KVSpinnerView.showProgress()' instead of showProgress() method and then you should call 'KVSpinnerView.handle(progress: progress)' method in downloadProgress handler:

KVSpinnerView.showProgress()
self.doSomeTask().downloadProgress { progress in
	DispatchQueue.main.async {
		KVSpinnerView.handle(progress: progress)
	}
	.response { response in
		DispatchQueue.main.async {
			KVSpinnerView.dismiss()
		}
	}
}

Customize

Also KVSpinnerView is highly customizable. You can customize it by changing KVSpinnerView.settings parameters, such as:

• animationStyle - type of Spinner's animation. For now there are 2 variants: standart(default) and infinite

• spinnerRadius- radius of KVSpinnerView. Background rectangle changes its size regarldess to this parameter

• backgroundRectColor - color of background rectangle

• statusTextColor - color of status message text

• minimumDismissDelay - KVSpinnerView will not be removed earlier than this parameter (in seconds)
