我在Expo中发现了这个问题，每当Stack.Navigator（@react-navigation/native-stack）更改屏幕时，从一个包含透明属性设置为true的Modal的屏幕，应用程序在iOS上崩溃（而不是在Android上）。
代码：

// Login.tsx file 

 <Modal transparent={true} visible={modalVisible} animationType='slide'>
                <View style={[styles.container, {justifyContent: "flex-end"}]}>
                    <View style={[styles.container, {flex: 0.8}]}> 
                        <TextInput onChangeText={(text) => setEmail(text)} value={email} autoCapitalize='none' style={styles.input} placeholder='email' placeholderTextColor={"#898989"}></TextInput>
                        <TextInput onChangeText={(text) => setPassword(text)} value={password} autoCapitalize='none' style={styles.input} placeholder='password' secureTextEntry placeholderTextColor={"#898989"}></TextInput>
                        {loading ? <ActivityIndicator size="large" color="#c59e69"/> : 
                        <>
                        <Button color="#c59e69" title="login" onPress={signIn}/>
                        <Button color="#c59e69" title="create account" onPress={signUp}/>
                        <Button color="#121212" title="Guest" onPress={guestAccess}/>
                        </>}
                    </View>
                </View> 
                <Button title="Remove Modal" onPress={() => setModalVisible(false)}/>
   </Modal>

字符串
signIn和guestAccess函数分别会导致firebase函数signInWithEmailAndPassword和signInAntively。这会更改Auth状态，然后更改App.tsx上的用户状态变量，该变量用于标识用户应该在哪个堆栈屏幕上：

// App.tsx

const Stack = createNativeStackNavigator()

export default function App() {

  const [user, setUser] = useState<User | null>(null)

  const auth = AUTH

  useEffect(() => {
    onAuthStateChanged(AUTH, (user) => setUser(user)) 
  
   
  }, [])
  

  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName='Login'>
        { user ? <Stack.Screen name='Inside' component={InsideLayout} options={{ headerShown: false,}}/> : <Stack.Screen name="Login" component={Login} options={{ headerShown: false}} />}
      </Stack.Navigator>
    </NavigationContainer>
  );
}

// This is my package.json

的数据

**你尝试了什么，你期待什么？**在改变屏幕之前尝试将透明设置为假，但不起作用。

编辑：也尝试了presentationStyle=“formSheet”，也崩溃了。
