篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了RN 使用第三方组件之react-native-image-picker相关的知识,希望对你有一定的参考价值。

首先给个github地址:https://github.com/react-community/react-native-image-picker 

该插件可以同时给iosandroid两个平台下使用,但是需要配置下各自平台下的文件

 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:

      手动添加库 :

  1. In the XCode\'s "Project navigator", right click on your project\'s Libraries folder ➜ Add Files to <...>
  2. Go to node_modules ➜ react-native-image-picker ➜ ios ➜ select RNImagePicker.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

(注意这里的只要出现RNImagePicker.就可以了,跟前面的图标没关系)

 

     

     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

(点击加号 选择privacy camera usage Description 和 privacy. PhotoLibraryUsageDescription )

iOS平台配置完毕.

Android:

    1.Add the following lines to android/settings.gradle:

1
2
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:

1
2
3
dependencies {
    compile project(\':react-native-image-picker\')
}

  

     3.Add the required permissions in AndroidManifest.xml:

1
2
<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:   

复制代码
复制代码
import com.imagepicker.ImagePickerPackage;


.........



 new ImagePickerPackage()
复制代码
复制代码

 

 

 

OK,安卓这边也配置完毕.

用法:

   配置弹出框信息

/**底部弹出框选项*/
var photoOptions = {
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

choosePhoto() {
ImagePicker.showImagePicker(photoOptions,(response) =>{
console.log(\'response\'+response);
if (response.didCancel){
showMsg("取消")
return
}else {
let source = { uri: response.uri };


}

})
}
