## Introduction

`NVActivityIndicatorView` is a collection of awesome loading animations.

## Installation

### Cocoapods

[Cocoapods](https://cocoapods.org/#install) is a dependency manager for Swift and Objective-C Cocoa projects. 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()`._
