Getting Started
---------------
* SwiftUI
```Swift
import SwiftUI
/// 🥳 # Step1: let's import!
import BSZoomGridScrollView
struct ContentView: View {
var itemsToZoom: [UIImage] = {
var images = [UIImage]()
for i in 0...29 {
images.append(UIImage(named: "yourImage\(i)") ?? UIImage())
}
return images
}()
var body: some View {
/// 😊 # Step2. That's it. completed!
BSZoomGridScrollView(itemsToZoom: itemsToZoom,
powerOfZoomBounce: .regular,
isBeingDraggingOnItem:{ selectedImage in
///
},
didLongPressItem: { selectedImage in
/// Grab an image user ends up choosing.
},
didFinishDraggingOnItem: { selectedImage in
/// Grab an image user ends up choosing.
})
.edgesIgnoringSafeArea(.all)
}
}
```
* UIKit
```Swift
///
/// To use BSZoomGridScrollView,
/// Please, Follow steps written in the comments with icon like 😀.
///
import SwiftUI
import UIKit
///
// 😚 #Step1: import BSZoomGridScrollView!
///
import BSZoomGridScrollView
class ViewController: UIViewController {
///
// 😋 #Step2: declare BSZoomGridScrollView
///
private lazy var zoomGridScrollViewController: BSZoomGridScrollViewController = { [unowned self] in
///
/// It can be used on both SwiftUI and UIKit.
/// To see how it works on SwiftUI,
/// please refer to comments in SwiftUI directory -> ContentView.swift
///
return BSZoomGridScrollViewController(itemsToZoom: self.itemsToZoom,
powerOfZoomBounce: .regular,
scrollEnableButtonTintColor: .black,
scrollEnableButtonBackgroundColor: .white,
isBeingDraggingOnItem:{ [unowned self] selectedImage in
///
},
didLongPressItem: { [unowned self] selectedImage in
/// Grab an image user end up choosing.
},
didFinishDraggingOnItem: { [unowned self] selectedImage in
/// on drag finished
})
}()
///
// prepare any item array to feed to BSZoomGridScrollViewController.
///
private var itemsToZoom: [Any] = {
var images = [UIImage]()
for i in 0...29 {
images.append(UIImage(named: "s\(i)") ?? UIImage())
}
return images
}()
///
// 😁 #Step3: Present it!
///
@IBAction func goToBSZoomGridScrollView(_ sender: Any) {

## Installation
There are four ways to use BSZoomGridScrollView in your project:
- using CocoaPods
- using Swift Package Manager
- manual install (build frameworks or embed Xcode Project)
### Installation with CocoaPods
[CocoaPods](http://cocoapods.org/) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. See the [Get Started](http://cocoapods.org/#get_started) section for more details.
#### Podfile
First,
```ruby
pod 'BSZoomGridScrollView'
```
then in your root project,
```ruby
pod install
```
### Installation with Swift Package Manager (Xcode 11+)
[Swift Package Manager](https://swift.org/package-manager/) (SwiftPM) is a tool for managing the distribution of Swift code as well as C-family dependency. From Xcode 11, SwiftPM got natively integrated with Xcode.
BSZoomGridScrollView support SwiftPM from version 5.1.0. To use SwiftPM, you should use Xcode 11 to open your project. Click `File` -> `Swift Packages` -> `Add Package Dependency`, enter [BSZoomGridScrollView repo's URL](https://github.com/boraseoksoon/BSZoomGridScrollView). Or you can login Xcode with your GitHub account and just type `BSZoomGridScrollView` to search.
After select the package, you can choose the dependency type (tagged version, branch or commit). Then Xcode will setup all the stuff for you.
If you're a framework author and use BSZoomGridScrollView as a dependency, update your `Package.swift` file:
```swift
let package = Package(
dependencies: [
.package(url: "https://github.com/boraseoksoon/BSZoomGridScrollView", from: "0.1.1")
],
// ...
)
```
