} @Override protected List<ReactPackage> getPackages() { return Arrays.<ReactPackage>asList( new MainReactPackage(), new SplashScreenReactPackage() //添加这一句 ); } }; @Override public ReactNativeHost getReactNativeHost() { return mReactNativeHost; } } ``` **iOS:** 1. 在 XCode的项目导航视图中单击 `Libraries``Add Files to [your project's name]` 2. 将 `SplashScreen.xcodeproj`添加到你的项目中,`node_modules``react-native-splash-screen``SplashScreen.xcodeproj` 3. 在XCode中打开`Build Phases``Link Binary With Libraries``libSplashScreen.a` 添加到你的项目中。 4. 如果在使用过过程中出现 `'SplashScreen.h' file not found`问题,你可以下面的代码添加到Header Search Paths中,步骤如下: 选择你的项目,TARGET → Build Settings → Search Paths → Header Search Paths 添加: `$(SRCROOT)/../node_modules/react-native-splash-screen/ios` ### 第三步(配置): **Android:** 更新你的 MainActivity.java 文件如下: ```java public class MainActivity extends ReactActivity { @Override protected void onCreate(Bundle savedInstanceState) { SplashScreen.show(this); // 添加这一句 super.onCreate(savedInstanceState); } // ...other code } ``` **iOS:** 更新你的AppDelegate.m 文件如下: ```obj-c #import "AppDelegate.h" #import "RCTRootView.h" #import "SplashScreen.h" // here @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // ...other code [SplashScreen show]; // 添加这一句,这一句一定要在最后 return YES; } @end ``` ## 使用说明 `react-native-splash-screen` 导入你的JS 文件。 `import SplashScreen from 'react-native-splash-screen'` **Android:** 创建一个名为 launch_screen.xml 的布局文件来自定义你的启动屏幕。 ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/launch_screen"> </LinearLayout> ``` **另外:** 你也可以启用app主题透明选项来解决在APP启动时因主题原因导致的短暂白屏的问题,具体步骤如下: 打开 `android/app/src/main/res/values/styles.xml`文件,添加 `<item name="android:windowIsTranslucent">true</item>`,如下 : ```xml <resources> <!-- Base application theme. --> <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- Customize your theme here. --> <!--设置透明背景--> + <item name="android:windowIsTranslucent">true</item> </style> </resources> ``` **更详细的介绍,可以查看 [examples](https://github.com/crazycodeboy/react-native-splash-screen/tree/master/examples)** **iOS** iOS可以通过LaunchImage或LaunchScreen.xib来自定义你的启动屏幕。 **更详细的介绍,可以查看 [examples](https://github.com/crazycodeboy/react-native-splash-screen/tree/master/examples)** 最后,你可以在适当的时候关闭启动屏幕(如:启动初始化完成后): ```JavaScript import SplashScreen from 'react-native-splash-screen' export default class WelcomePage extends Component { componentDidMount() { // do anything while splash screen keeps, use await to wait for an async task. SplashScreen.hide();//关闭启动屏幕 } } ``` ## API 方法 | 类型 | 可选 | 描述 ----------------- | -------- | -------- | ----------- show() | function | false | 打开启动屏幕 hide() | function | false | 关闭启动屏幕 ## 贡献 欢迎大家提问题,如果能给问题加上一个截图,则是极好的。另外欢迎`Pull requests`贡献你的代码。 --- **MIT Licensed**
