# ZoomableScrollView
A Simple Zoomable ScrollView with a View inherited from UIScrollView.
### About
When you make an application, which has a viewer feature(like big photo viewer), the viewer usually needs to have zoomable and scrollable features, to allow the user to view more details.
This control help you display a view, with zoomable and scrollable features easily.
#### Compatible
- iOS 7 and later (requires iOS 8 if you want to add it to project using CocoaPod)
- Swift 4.0(version 1.5), Swift 3.0 (version 1.3), 2.0 (version 1.2 and prior)
### Usage
#### Cocoapod
Add below line to Podfile or Run below command in Terminal to install(not support pod api yet):
```
pod 'ZoomableScrollView', :git => 'https://github.com/tucan9389/ZoomableScrollView.git'
```
#### Manual
In iOS 7, you cannot use Cocoapod to install. In this case, you need add it manually. Simply, add file `ZoomableScrollView.swift` in folder `Sources` to your project
#### Simple to use
Drag an UIScrollView to your storyboard, change Class and Module in Identity Inspector to ZoomableScrollView. Also, create an IBOutlet in your source file.
```swift
import ZoomableScrollView
class ViewController: UIViewController
@IBOutlet weak var zoomableScrollView: ZoomableScrollView!
let myView = MyCustomView()
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
zoomableScrollView.display(view: myView)
// or
zoomableScrollView.display(image: UIImage(named: "image"))
}
}
```
That's all. Now try zooming and scrolling to see the result.
Note: If your view is aligned left instead of center, try calling below method:
```superViewOfZoomableScrollView.layoutIfNeeded()```
`superViewOfZoomableScrollView` is the view that ZoomableScrollView is added to.
### Features
- Simple to create zoomable scroll view
- Double tap to zoom feature
- Smoother. Fixed bug when zooming out, the control auto zooms from center, and not from the corner.
- Various `ZoomMode`(`.defaultFit`, `aspectFill`, `aspectFit`, `widthFill`, `heightFill`)
