## Requirements
- iOS 8.0+
- Swift 4.2+
- Xcode 10.0+
## Installation
### CocoaPods
[CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects. You can install it with the following command:
```bash
$ gem install cocoapods
```
> CocoaPods 1.1.0+ is required to build NFDownloadButton 0.0.6+.
To integrate NFDownloadButton into your Xcode project using CocoaPods, specify it in your `Podfile`:
```ruby
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!
pod 'NFDownloadButton', '~> 0.0.6'
```
Then, run the following command:
```bash
$ pod install
```
### Carthage
[Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.
You can install Carthage with [Homebrew](http://brew.sh/) using the following command:
```bash
$ brew update
$ brew install carthage
```
To integrate NFDownloadButton into your Xcode project using Carthage, specify it in your `Cartfile`:
```ogdl
github "LeonardoCardoso/NFDownloadButton" ~> 0.0.6
```
### Manually
If you prefer not to use either of the aforementioned dependency managers, you can integrate NFDownloadButton into your project manually.
## Usage
You can use a `NFDownloadButton` on [Storyboards](#storyboard) or, if you want to do it programatically, you can create it just like you create a UIButton:
```swift
let downloadButton = NFDownloadButton(frame: CGRect(x: 0, y: 0, width: 50, height: 50))
self.parentView.addSubview(downloadButton)
```
`NFDownloadButton` has four states:
| State 1: To Download | State 2: Will Download | State 3: Ready to Download | State 4: Downloaded |
|:-:|:-:|:-:|:-:|
|  |  |  |  |
You can switch between states by just doing as following:
```swift
self.downloadButton.downloadState = .toDownload || .willDownload || .readyToDownload || .downloaded
```
When the button is in `.readyToDownload` state, the button will wait for your to upload its progress. You can do it like this:
```swift
self.downloadButton.downloadPercent = 0.5
```
When this value reaches 1.0, then `downloadState` is automatically changed to `.downloaded`.
### Downloaded by default
You can select the button as downloaded by default. All states will be overridden by `Downloaded` state and no animation will be performed. To do so, just add `isDownloaded` in its constructor, or set it up whenever you want.
```swift
NFDownloadButton(frame: CGRect(x: 0, y: 0, width: 50, height: 50), isDownloaded: true)
```
```swift
downloadButton.isDownloaded = true
```
### Style
`NFDownloadButton` has four different styles of devices: `iOS`, `watchOS`, `tvOS`, `macOS`. Thus you can customize your final result. This option is only available on constructor.
```swift
NFDownloadButton(frame: CGRect(x: 0, y: 0, width: 50, height: 50), isDownloaded: true,
style: .iOS)
```
| iOS | watchOS | tvOS | macOS |
|:-:|:-:|:-:|:-:|
|  |  |  |  |
### Palette
You also can customize the colors of the button on its constructor.
```swift
NFDownloadButton(
frame: wrapView.frame,
isDownloaded: true,
style: .iOS,
palette: Palette(
initialColor: UIColor?,
rippleColor: UIColor?,
buttonBackgroundColor: UIColor?,
downloadColor: UIColor?,
deviceColor: UIColor?
)
)
```
### Delegate
You can watch changes of state by implementing the protocol:
```swift
protocol NFDownloadButtonDelegate {
func stateChanged(button: NFDownloadButton, newState: NFDownloadButtonState)
}
```
### Storyboard
Last but not least, you can customize `NFDownloadButton` properties right from Interface Builder or Storyboards.
