为什么Dimensions.get（'window'）。height在iOS上返回0？

Question

对于iOS：Dimensions.get（'window'）。height = 0

但是Dimensions.get（'screen'）。height =某物

为什么可以？

console.log('DIMENSIONS', Dimensions.get('window'), Dimensions.get('screen'));


// logs
window = {fontScale: 1, height: 0, width: 0, scale: 2} 
screen = {fontScale: 1, height: 896, width: 414, scale: 2}

已修复。 RNSplashScreen在AppDelegate.m中存在问题。

问题代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [RNSplashScreen show]; // here

    // ...other code
    return YES;
}

工作：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // ...other code

    [RNSplashScreen show];  // here
    // or
    //[RNSplashScreen showSplash:@"LaunchScreen" inRootView:rootView];
    return YES;
}
