iOS 上的 React Native 启动画面

Question

我正在使用 React Native 开发一个应用程序，并尝试在 ios 上添加启动屏幕。我在 AppDelegate.mm 上添加了以下代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  self.moduleName = @"eCare";
  // You can add your custom initial props in the dictionary below.
  // They will be passed down to the ViewController used by React Native.
  self.initialProps = @{};
  [RNSplashScreen show]; //Added this line

  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}

此后我的应用程序卡在启动屏幕中。我将启动屏幕隐藏在 React Native 的根屏幕上。我按照官方指南这里

Answer 1

我查看了库的doc，发现您的 AppDelegate 代码有所不同。看到方法最后

didFinishLaunchWithOptions

有一个

return YES

，尝试用这个代替

 return [super application:application didFinishLaunchingWithOptions:launchOptions];

，看看是否有效。如果它不起作用，请回答，以便我们尝试找到另一个答案。

Answer 2

切换返回 [超级应用程序:application didFinishLaunchingWithOptions:launchOptions];

与以下...

bool didFinish=[超级应用程序:应用程序didFinishLaunchingWithOptions:launchOptions];

[RNSplashScreen 显示]; // 这里返回 didFinish;

Answer 3

#import "RNSplashScreen.h" // At top

- (BOOL)application:(UIApplication *)application 
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
     {
self.moduleName = @"abc";
// You can add your custom initial props in the dictionary below.
// They will be passed down to the ViewController used by React Native.
self.initialProps = @{};

// Add these lines ----------------
[super application:application didFinishLaunchingWithOptions:launchOptions];
[RNSplashScreen show];
return true;
}
