我有一个与本机导航有关的问题
const Swipe = ({signUp}) => {
const Stack= createStackNavigator()
return(
<NavigationContainer>
<Stack.Navigator screenOptions= {{headerBackTitleStyle:{color:'white'}}}>
<Stack.Screen name="SignUp" options={
{
headerStyle: {
backgroundColor: Color.Primary
},
}
}>
{
()=>(
<SignUp signUp={signUp}/>
)
}
</Stack.Screen>
<Stack.Screen name="SignIn" component={SignIn} options= {
({navigation, route})=> ({
HeaderTitle: ()=> route.params.name,
headerStyle: {
backgroundColor: Color.Primary
}
})
}/>
</Stack.Navigator>
</NavigationContainer>
)
}
export default Swipe
in the root app:
<Swipe signUp= {signUp}/>
问题是我何时将signUp函数传递给导航 它可以正常工作,但是当我导航到signIn组件时,它表明导航错误是未定义的对象
有人可以帮助我
答案 0 :(得分:0)
是否可能没有将登录组件作为道具提供?像:
const Swipe = ({signUp, signIn}) => {
const Stack= createStackNavigator()
return(........)
})
