最近需要在react native项目中集成相机和相册的功能,于是在网上找了一个好用的第三方插件:react-native-image-picke.
该插件可以同时给iOS和Android两个平台下使用,但是需要配置下各自平台下的文件,github上有详细的文字说明,但是本人对于文字向来无感,所以特地图解记录下配置说明和用法.
1. 首先,安装下该插件:
npm install react-native-image-picker@latest --save
2. 先别link,先添加进来该库之后 再link.
下面对于各自平台进行配置即可.
iOS:
- In the XCode's "Project navigator", right click on your project's Libraries folder ➜
Add Files to <...>
- Go to
node_modules
➜react-native-image-picker
➜ios
➜ selectRNImagePicker.xcodeproj
=> 打开Xcode打开项目,点击根目录,右键选择 Add Files to 'XXX',选中项目中的该路径下的文件即可:node_modules
➜ react-native-image-picker
➜ ios
➜ select RNImagePicker.xcodeproj
OK,添加进来之后,再进行 link命令. react-native link react-native-image-picker
3.Add RNImagePicker.a
to Build Phases -> Link Binary With Libraries
4.For iOS 10+, Add the NSPhotoLibraryUsageDescription
and NSCameraUsageDescription
keys to your Info.plist
with strings describing why your app needs these permissions
=>对于适配iOS10,需要在info.plist中配置NSPhotoLibraryUsageDescription和NSCameraUsageDescription
iOS平台配置完毕.
Android:
1.Add the following lines to android/settings.gradle
:
include ':react-native-image-picker' project(':react-native-image-picker').projectDir = new File(settingsDir, '../node_modules/react-native-image-picker/android')
2.Add the compile line to the dependencies in android/app/build.gradle
:
dependencies { compile project(':react-native-image-picker') }
3.Add the required permissions in AndroidManifest.xml
:
<uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
4.Add the import and link the package in MainApplication.java
:
import com.imagepicker.ImagePickerPackage; ......... new ImagePickerPackage()
OK,安卓这边也配置完毕.
用法:
配置弹出框信息
import ImagePicker from 'react-native-image-picker'; //第三方相机 var photoOptions = { //底部弹出框选项 title:'请选择', cancelButtonTitle:'取消', takePhotoButtonTitle:'拍照', chooseFromLibraryButtonTitle:'选择相册', quality:0.75, allowsEditing:true, noData:false, storageOptions: { skipBackup: true, path:'images' } }
点击事件
cameraAction = () =>{ ImagePicker.showImagePicker(photoOptions,(response) =>{ console.log('response'+response); if (response.didCancel){ return } }) }
