</p>

## 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

## Step 1

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

## Step 2

### iOS

#### - If you use Cocoapods which is highly recommended:

```bash
cd ios
pod init
```

After this edit Podfile. Example content is following:

```bash
platform :ios, '8.0'

target '<project_name>' do
  # this is very important to have!
  rn_path = '../node_modules/react-native'
  pod 'yoga', path: "#{rn_path}/ReactCommon/yoga/yoga.podspec"
  pod 'React', path: rn_path, subspecs: [
    'Core',
    'RCTActionSheet',
    'RCTAnimation',
    'RCTGeolocation',
    'RCTImage',
    'RCTLinkingIOS',
    'RCTNetwork',
    'RCTSettings',
    'RCTText',
    'RCTVibration',
    'RCTWebSocket'
  ]

  pod 'RNImageCropPicker', :path =>  '../node_modules/react-native-image-crop-picker'
end

# very important to have, unless you removed React dependencies for Libraries 
# and you rely on Cocoapods to manage it
post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end
  end
end
```

After this run:

```bash
pod install
```

After this use `ios/<project_name>.xcworkspace`. **Do not use** `ios/<project_name>.xcodeproj`.

#### - If you are not using Cocoapods which is not recommended:

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

### Android

```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

##### Only if you are not using Cocoapods

- 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`
  
#### Step Optional - To localizate the camera / gallery text buttons

- Open your Xcode project
- Go to your project settings by opening the project name on the Navigation (left side)
- Select your project in the project list 
- Should be into the Info tab and add in Localizations the language your app was missing throughout the +
- Rebuild and you should now have your app camera and gallery with the classic ios text in the language you added.

### Android

- Make sure you are using Gradle >= `2.2.x` (android/build.gradle)

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

- **VERY IMPORTANT** Add the following to your `build.gradle`'s repositories section. (android/build.gradle)

```gradle
allprojects {
    repositories {
      mavenLocal()
      jcenter()
      maven { url "$rootDir/../node_modules/react-native/android" }

      // ADD THIS
      maven { url 'https://maven.google.com' }

      // ADD THIS
      maven { url "https://jitpack.io" }
    }
}
```

- Add `useSupportLibrary` (android/app/build.gradle)

```gradle
android {
    ...

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

- Use Android SDK >= 26 (android/app/build.gradle)

```gradle
android {
    compileSdkVersion 27
    buildToolsVersion "27.0.3"
    ...
    
    defaultConfig {
      ...
      targetSdkVersion 27
      ...
    }
    ...
}
```

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

- [Optional] If you want to use front camera, also add following to `app\src\main\AndroidManifest.xml`
  - `<uses-feature android:name="android.hardware.camera" android:required="false" />`
  - `<uses-feature android:name="android.hardware.camera.front" android:required="false" />`

## 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`)

## TO DO

- [ ] [Android] Standardize multiple select
- [ ] [Android] Video compression
