Image cropping plugin which supported different devices orientation. Easy to set up and configure. Has many settings for flexible integration into your project. Behavior is similar to native iOS photo cropper.
## Features
- [x] Overlay view & Crop rectangle full customization
- [x] Flexible settings
- [x] Image rotation
- [x] Infinite "Zoom To Fit"
- [x] Full image resolution
- [x] Ability to draw custom crop rectangle
## Requirements
- iOS 8.0+
- Xcode 7.3
## Installation
### CocoaPods
[CocoaPods][] is a dependency manager for Cocoa projects. To install **AKImageCropperView** with CocoaPods:
1. Make sure CocoaPods is [installed][CocoaPods Installation].
2. Update your Podfile to include the following:
``` ruby
use_frameworks!
pod 'AKImageCropperView'
```
3. Run `pod install`.
[CocoaPods]: https://cocoapods.org
[CocoaPods Installation]: https://guides.cocoapods.org/using/getting-started.html#getting-started
4. In your code import **AKImageCropperView** like so: `import AKImageCropperView`
### Carthage
[Carthage][] is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.
To install **AKImageCropperView** with Carthage:
1. Install Carthage via [Homebrew][]
```bash
$ brew update
$ brew install carthage
```
2. Add `github "artemkrachulov/AKImageCropperView"` to your Cartfile.
3. Run `carthage update`.
4. Drag `AKMaskField.framework ` from the `Carthage/Build/iOS/` directory to the `Linked Frameworks and Libraries` section of your Xcode project’s `General` settings.
5. Add `$(SRCROOT)/Carthage/Build/iOS/AKImageCropperView.framework ` to `Input Files` of Run Script Phase for Carthage.
[Carthage]: https://github.com/Carthage/Carthage
[Homebrew]: http://brew.sh
### Manual
If you prefer not to use either of the aforementioned dependency managers, you can integrate **AKImageCropperView** into your project manually.
1. Download and drop **AKImageCropperView** folder in your project.
2. Done!
## Usage example
### Storyboard
```swift
@IBOutlet weak var cropView: AKImageCropperView!
override func viewDidLoad() {
super.viewDidLoad()
cropView.image = UIImage(named: "yourImage")
}
```
### Programmatically
```swift
var cropView: AKImageCropperView!
override func viewDidLoad() {
super.viewDidLoad()
cropView = AKImageCropperView(frame: CGRect(x: 0, y: 20.0, width: 375.0, height: 607.0))
cropView.image = UIImage(named: "yourImage")
view.addSubview(cropViewProgrammatically)
}
```
> Full examples with constraint, delegates and Overlay view configuration check in demo project.
>
> **NOTE**: If after cropper view initialization your image has top inset. Go to storyboard with your scene and in the attributes inspector, uncheck 'Adjust Scrollview Insets'.
## Initializing an Image Cropper View
```swift
func init(image: UIImage?)
```
Returns an image cropper view initialized with the specified image.
**Parameters**
- `image` : The initial image to display in the image cropper view.
## Accessing the Displayed Images
```swift
var image: UIImage? { get set }
```
The image displayed in the image cropper view.
Default value of this property is `nil`.
```swift
var croppedImage: UIImage? { get }
```
Cropperd image in the specified crop rectangle.
## Instance Properties
```swift
var isEdited: UIImage? { get }
```
Returns the image edited state flag.
## Managing the Delegate
```swift
weak var delegate: AKImageCropperViewDelegate? { get set }
```
The delegate of the cropper view object.
### Delegate methods
```swift
optional func imageCropperViewDidChangeCropRect(view: AKImageCropperView, cropRect rect: CGRect)
```
Tells the delegate that crop frame was changed.
Parameters:
- **`view`**: The image cropper view.
- **`rect`**: New crop rectangle origin and size.
## Customizing an Overlay View
```swift
var overlayView: AKImageCropperOverlayView? { get set }
```
Overlay view represented as AKImageCropperOverlayView open class.
