# react-native-syan-image-picker
## Getting started
`$ npm install react-native-syan-image-picker --save`
### Mostly automatic installation
`$ react-native link react-native-syan-image-picker`
### Manual installation
#### iOS
1. In XCode, in the project navigator, right click `Libraries` ➜ `Add Files to [your project's name]`
2. Go to `node_modules` ➜ `react-native-syan-image-picker` and add `RNSyanImagePicker.xcodeproj`
3. In XCode, in the project navigator, select your project. Add `libRNSyanImagePicker.a` to your project's `Build Phases` ➜ `Link Binary With Libraries`
4. Run your project (`Cmd+R`)<
#### Android
1. Open up `android/app/src/main/java/[...]/MainActivity.java`
- Add `import com.reactlibrary.RNSyanImagePickerPackage;` to the imports at the top of the file
- Add `new RNSyanImagePickerPackage()` to the list returned by the `getPackages()` method
2. Append the following lines to `android/settings.gradle`:
```
include ':react-native-syan-image-picker'
project(':react-native-syan-image-picker').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-syan-image-picker/android')
```
3. Insert the following lines inside the dependencies block in `android/app/build.gradle`:
```
compile project(':react-native-syan-image-picker')
```
#### Windows
[Read it! :D](https://github.com/ReactWindows/react-native)
1. In Visual Studio add the `RNSyanImagePicker.sln` in `node_modules/react-native-syan-image-picker/windows/RNSyanImagePicker.sln` folder to their solution, reference from their app.
2. Open up your `MainPage.cs` app
- Add `using Com.Reactlibrary.RNSyanImagePicker;` to the usings at the top of the file
- Add `new RNSyanImagePickerPackage()` to the `List<IReactPackage>` returned by the `Packages` method
## Usage
```javascript
import RNSyanImagePicker from 'react-native-syan-image-picker';
// TODO: What to do with the module?
RNSyanImagePicker;
```

/*
经过测试，比起xib的方式，把TZAssetCell改用纯代码的方式来写，滑动帧数明显提高了（约提高10帧左右）
最初发现这个问题并修复的是@小鱼周凌宇同学，她的博客地址: http://zhoulingyu.com/
表示感谢~
原来xib确实会导致性能问题啊...大家也要注意了...
