# InteractiveZoomDriver
This repo is view to zoomable by pinch gesture.
## Overview
## Installation
### Swift Package Manager
For installing with SPM, add it to your `Package.swift`.
```swift
dependencies: [
.package(url: "https://github.com/shima11/InteractiveZoomDriver.git", from: "1.2.5"))
]
```
### Carthage
For installing with Carthage, add it to your `Cartfile`.
```
github "shima11/InteractiveZoomDriver"
```
### CocoaPods
For installing with CocoaPods, add it to your `Podfile`.
```
pod 'InteractiveZoomDriver'
```
## Usage
```
import InteractiveZoomDriver
let zoomView = UIImageView() // UIView or SubClass of UIView
zoomView.isUserInteractionEnabled = true
```
### Case1: driver
Add zoom function to target UIView.
`gestureTargetView`: added tap and pan gesture.
`sourceView`: source view.
`targetViewFactory`: Transformed View during zooming.
`shouldZoomTransform`: Delegate to the outside whether zooming is possible.
```
let driver = InteractiveZoomDriver(
gestureTargetView: imageView2,
sourceView: imageView2,
targetViewFactory: { (fromImageView: UIImageView) -> UIView in
let view = UIImageView()
view.image = fromImageView.image
view.clipsToBounds = fromImageView.clipsToBounds
view.contentMode = fromImageView.contentMode
return view
},
shouldZoomTransform: {(sourceView: UIImageView) -> Bool in
if sourceView.image == nil {
return false
}
return true
}
)
```
This is also no problem.
`InteractiveZoomView.clone` and `InteractiveZoomView.shouldZoomTransform` is default implementation of protocol extension.
`InteractiveZoomView` corresponds to `UIImageView` only.
To support other than `UIImageView`, add an implementation in extension.
```
let driver = InteractiveZoomDriver(
gestureTargetView: zoomView,
sourceView: zoomView,
targetViewFactory: InteractiveZoomView.clone,
shouldZoomTransform: InteractiveZoomView.shouldZoomTransform
)
```
### Case2: overlay view
InteractiveZoomView is able to only UIImageView now.
If you want to use custom UIView, you need to create extension of InteractiveZoomView with reference to InteractiveZoomView.
```
let overlayZoomView = InteractiveZoomView(
sourceView: zoomView
)
view.addSubView(overlayZoomView)
```
