## Usage

Import library

```javascript
import ImagePicker from 'react-native-image-crop-picker';
```

### Select from gallery

Call single image picker with cropping
```javascript
ImagePicker.openPicker({
  width: 300,
  height: 400,
  cropping: true
}).then(image => {
  console.log(image);
});
```

Call multiple image picker

```javascript
ImagePicker.openPicker({
  multiple: true
}).then(images => {
  console.log(images);
});
```

Select video only from gallery

```javascript
ImagePicker.openPicker({
  mediaType: "video",
}).then((video) => {
  console.log(video);
});
```

**Android: The prop 'cropping' has been known to cause videos not to be display in the gallery on Android. Please do not set cropping to true when selecting videos.**


### Select from camera

```javascript
ImagePicker.openCamera({
  width: 300,
  height: 400,
  cropping: true
}).then(image => {
  console.log(image);
});
```

### Crop picture

```javascript
ImagePicker.openCropper({
  path: 'my-file-path.jpg',
  width: 300,
  height: 400
}).then(image => {
  console.log(image);
});
```

### Optional cleanup

Module is creating tmp images which are going to be cleaned up automatically somewhere in the future. If you want to force cleanup, you can use `clean` to clean all tmp files, or `cleanSingle(path)` to clean single tmp file.

```javascript
ImagePicker.clean().then(() => {
  console.log('removed all tmp images from tmp directory');
}).catch(e => {
  alert(e);
});
```

# Install

## Install package

```bash
npm i react-native-image-crop-picker --save
```

Link the package using react-native link:

```bash
react-native link react-native-image-crop-picker
```

## Post-install steps

### iOS

#### Step 1:

In Xcode open Info.plist and add string key `NSPhotoLibraryUsageDescription` with value that describes why you need access to user photos. More info here https://forums.developer.apple.com/thread/62229. Depending on what features you use, you also may need `NSCameraUsageDescription` and `NSMicrophoneUsageDescription` keys.

#### Step 2:

##### Cocoapods (Highly recommended)

```bash
cd ios
pod init
```

After this you have to add pod dependencies to `Podfile`. Open `Podfile` with your editor, and add or adjust example configuration:

```bash
platform :ios, '8.0'

target '<your_project_name>' do
    pod 'RSKImageCropper'
    pod 'QBImagePickerController'
end
```

After this run:

```bash
pod install
```

##### Manual

- Drag and drop the ios/ImageCropPickerSDK folder to your xcode project. (Make sure Copy items if needed IS ticked)
- Click on project General tab
  - Under `Deployment Info` set `Deployment Target` to `8.0`
  - Under `Embedded Binaries` click `+` and add `RSKImageCropper.framework` and `QBImagePicker.framework`

### Android

- Make sure you are using Gradle `2.2.x` (project build.gradle)

```gradle
buildscript {
    ...
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
        ...
    }
    ...
}
```

- Add the following to your `build.gradle`'s repositories section. (project build.gradle)

```gradle
allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}
```

- Add `useSupportLibrary` (app build.gradle)

```gradle
android {
    ...

    defaultConfig {
        ...
        vectorDrawables.useSupportLibrary = true
        ...
    }
    ...
}
```

- [Optional] If you want to use camera picker in your project, add following to `AndroidManifest.xml`
  - `<uses-permission android:name="android.permission.CAMERA"/>`

## Production build

### iOS

#### Cocoapods (Highly recommended)

- You are already done

#### Manual

If you are using pre-built frameworks from `ios/ImageCropPickerSDK`, then before deploying app to production you should strip off simulator ARCHs from these, or you can add frameworks from `Libraries/imageCropPicker/Libraries/_framework_name_.xcodeproj/Products/_framework_name_.framework` to Embedded Binaries instead of pre-built ones.
Related issue: https://github.com/ivpusic/react-native-image-crop-picker/issues/61.

Details for second approach:

1. Remove the pre-built frameworks from `Embedded Binaries`
2. Build for Device
3. Add the newly built binaries for both frameworks to `Embedded Binaries` (located at `Libraries/imageCropPicker/Libraries/_framework_name_.xcodeproj/Products/_framework_name_.framework`)
