To use NVActivityIndicatorView with CocoaPods, add it in your `Podfile`. ```ruby pod 'NVActivityIndicatorView' ``` ### Carthage [Carthage](https://github.com/Carthage/Carthage#installing-carthage) is intended to be the simplest way to add frameworks to your Cocoa application. To use NVActivityIndicatorView with Carthage, add it in your `Cartfile`. ```ruby github "ninjaprox/NVActivityIndicatorView" ``` ### Swift Package Manager The [Swift Package Manager](https://swift.org/package-manager/) is a tool for managing the distribution of Swift code. To use NVActivityIndicatorView with Swift Package Manger, add it to `dependencies` in your `Package.swift` ```swift dependencies: [ .package(url: "https://github.com/ninjaprox/NVActivityIndicatorView.git") ] ``` ## Migration Version [5.0.0](https://github.com/ninjaprox/NVActivityIndicatorView/releases/tag/5.0.0) comes with breaking changes. Please refer to the release note for details. ## Usage Firstly, import `NVActivityIndicatorView`. ```swift import NVActivityIndicatorView ``` ### Initialization Then, there are two ways you can create `NVActivityIndicatorView`: - By storyboard, changing class of any `UIView` to `NVActivityIndicatorView`. _**Note:** Set `Module` to `NVActivityIndicatorView`._ - By code, using initializer. All parameters other than `frame` are optional and [`NVActivityIndicatorView.DEFAULT_*`](https://nvactivityindicatorview.vinhis.me/Classes/NVActivityIndicatorView.html) are used as default values. ```swift NVActivityIndicatorView(frame: frame, type: type, color: color, padding: padding) ``` ### Control Start animating. ```swift activityIndicatorView.startAnimating() ``` Stop animating. ```swift activityIndicatorView.stopAnimating() ``` Determine if it is animating. ```swift animating = activityIndicatorView.isAnimating ``` ### Change properties In storyboard, you can change all properties in Attributes inspector tab of Utilities panel. _**Note:** Use one of values (case-insensitive) in [Animation types](#animation-types) for `Type Name`._ All properties are public so you can change them after initializing. _**Note:** All changes must be made before calling `startAnimating()`._ ## Documentation https://nvactivityindicatorview.vinhis.me/ ## Acknowledgment Thanks [Connor Atherton](https://github.com/ConnorAtherton) for inspired [Loaders.css](https://github.com/ConnorAtherton/loaders.css) and [Danil Gontovnik](https://github.com/gontovnik) for [DGActivityIndicatorView](https://github.com/gontovnik/DGActivityIndicatorView). ## License The MIT License (MIT) Copyright (c) 2016 Vinh Nguyen [@ninjaprox](http://twitter.com/ninjaprox) ================================================ FILE: Sources/Base/Animations/NVActivityIndicatorAnimationAudioEqualizer.swift ================================================ // // NVActivityIndicatorAnimationAudioEqualizer.swift // NVActivityIndicatorView // // The MIT License (MIT) // Copyright (c) 2016 Vinh Nguyen // Permission is hereby granted, free of charge, to any person obtaining a copy // of this software and associated documentation files (the "Software"), to deal // in the Software without restriction, including without limitation the rights // to use, copy, modify, merge, publish, distribute, sublicense, and/or sell // copies of the Software, and to permit persons to whom the Software is // furnished to do so, subject to the following conditions: // The above copyright notice and this permission notice shall be included in all // copies or substantial portions of the Software. // THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR // IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, // FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

NVActivityIndicatorView

Activity indicator view with nice animations

  • Default type. Default value is .BallSpinFadeLoader.

  • Default color of activity indicator. Default value is UIColor.white.

  • Default color of text. Default value is UIColor.white.

  • Default padding. Default value is 0.

  • Default size of activity indicator view in UI blocker. Default value is 60x60.

  • Default display time threshold to actually display UI blocker. Default value is 0 ms.

    Note

    Default time that has to be elapsed (between calls of startAnimating() and stopAnimating()) in order to actually display UI blocker. It should be set thinking about what the minimum duration of an activity is to be worth showing it to the user. If the activity ends before this time threshold, then it will not be displayed at all.

  • Default minimum display time of UI blocker. Default value is 0 ms.

    Note

    Default minimum display time of UI blocker. Its main purpose is to avoid flashes showing and hiding it so fast. For instance, setting it to 200ms will force UI blocker to be shown for at least this time (regardless of calling stopAnimating() ealier).

  • Default message displayed in UI blocker. Default value is nil.

  • Default message spacing to activity indicator view in UI blocker. Default value is 8.

  • Default font of message displayed in UI blocker. Default value is bold system font, size 20.

  • Default background color of UI blocker. Default value is UIColor(red: 0, green: 0, blue: 0, alpha: 0.5)

  • Default fade in animation.

  • Default fade out animation.

  • Animation type.

  • Color of activity indicator view.

  • Padding of activity indicator view.

  • Current status of animation, read-only.

  • Returns an object initialized from data in a given unarchiver. self, initialized using the data in decoder.

  • Create a activity indicator view.

    Appropriate NVActivityIndicatorView.DEFAULT_* values are used for omitted params.

  • Returns the natural size for the receiving view, considering only properties of the view itself.

    A size indicating the natural size for the receiving view based on its intrinsic properties.

  • Start animating.

  • Stop animating.

NVActivityIndicatorView

Activity indicator view with nice animations

  • Default type. Default value is .BallSpinFadeLoader.

  • Default color of activity indicator. Default value is UIColor.white.

  • Default color of text. Default value is UIColor.white.

  • Default padding. Default value is 0.

  • Default size of activity indicator view in UI blocker. Default value is 60x60.

  • Default display time threshold to actually display UI blocker. Default value is 0 ms.

    Note

    Default time that has to be elapsed (between calls of startAnimating() and stopAnimating()) in order to actually display UI blocker. It should be set thinking about what the minimum duration of an activity is to be worth showing it to the user. If the activity ends before this time threshold, then it will not be displayed at all.

  • Default minimum display time of UI blocker. Default value is 0 ms.

    Note

    Default minimum display time of UI blocker. Its main purpose is to avoid flashes showing and hiding it so fast. For instance, setting it to 200ms will force UI blocker to be shown for at least this time (regardless of calling stopAnimating() ealier).

  • Default message displayed in UI blocker. Default value is nil.

  • Default message spacing to activity indicator view in UI blocker. Default value is 8.

  • Default font of message displayed in UI blocker. Default value is bold system font, size 20.

  • Default background color of UI blocker. Default value is UIColor(red: 0, green: 0, blue: 0, alpha: 0.5)

  • Default fade in animation.

  • Default fade out animation.

  • Animation type.

  • Color of activity indicator view.

  • Padding of activity indicator view.

  • Current status of animation, read-only.

  • Returns an object initialized from data in a given unarchiver. self, initialized using the data in decoder.

  • Create a activity indicator view.

    Appropriate NVActivityIndicatorView.DEFAULT_* values are used for omitted params.

  • Returns the natural size for the receiving view, considering only properties of the view itself.

    A size indicating the natural size for the receiving view based on its intrinsic properties.

  • Start animating.

  • Stop animating.

Installation

Cocoapods

Cocoapods is a dependency manager for Swift and Objective-C Cocoa projects. To use NVActivityIndicatorView with CocoaPods, add it in your Podfile.

pod 'NVActivityIndicatorView'

Carthage

Carthage is intended to be the simplest way to add frameworks to your Cocoa application. To use NVActivityIndicatorView with Carthage, add it in your Cartfile.

github "ninjaprox/NVActivityIndicatorView"

Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code. To use NVActivityIndicatorView with Swift Package Manger, add it to dependencies in your Package.swift

dependencies: [
    .package(url: "https://github.com/ninjaprox/NVActivityIndicatorView.git")
]

Migration

Version 5.0.0 comes with breaking changes. Please refer to the release note for details.

Usage

Firstly, import NVActivityIndicatorView.

import NVActivityIndicatorView

Initialization

Then, there are two ways you can create NVActivityIndicatorView:

Note: Set Module to NVActivityIndicatorView.

NVActivityIndicatorView(frame: frame, type: type, color: color, padding: padding)

Control

Start animating.

activityIndicatorView.startAnimating()

Stop animating.

activityIndicatorView.stopAnimating()

Determine if it is animating.

animating = activityIndicatorView.isAnimating

Change properties

In storyboard, you can change all properties in Attributes inspector tab of Utilities panel.

Note: Use one of values (case-insensitive) in Animation types for Type Name.

All properties are public so you can change them after initializing.

Note: All changes must be made before calling startAnimating().

Installation

Cocoapods

Cocoapods is a dependency manager for Swift and Objective-C Cocoa projects. To use NVActivityIndicatorView with CocoaPods, add it in your Podfile.

pod 'NVActivityIndicatorView'

Carthage

Carthage is intended to be the simplest way to add frameworks to your Cocoa application. To use NVActivityIndicatorView with Carthage, add it in your Cartfile.

github "ninjaprox/NVActivityIndicatorView"

Swift Package Manager

The Swift Package Manager is a tool for managing the distribution of Swift code. To use NVActivityIndicatorView with Swift Package Manger, add it to dependencies in your Package.swift

dependencies: [
    .package(url: "https://github.com/ninjaprox/NVActivityIndicatorView.git")
]

Migration

Version 5.0.0 comes with breaking changes. Please refer to the release note for details.

Usage

Firstly, import NVActivityIndicatorView.

import NVActivityIndicatorView

Initialization

Then, there are two ways you can create NVActivityIndicatorView:

Note: Set Module to NVActivityIndicatorView.

NVActivityIndicatorView(frame: frame, type: type, color: color, padding: padding)

Control

Start animating.

activityIndicatorView.startAnimating()

Stop animating.

activityIndicatorView.stopAnimating()

Determine if it is animating.

animating = activityIndicatorView.isAnimating

Change properties

In storyboard, you can change all properties in Attributes inspector tab of Utilities panel.

Note: Use one of values (case-insensitive) in Animation types for Type Name.

All properties are public so you can change them after initializing.

Note: All changes must be made before calling startAnimating().
