我有这个问题,我的代码运行良好,但如果我输入一个Accessory Right or Left错误Nothing was returned from the render。在其他屏幕上它工作得很好,但在这个屏幕上它是不可能的。UIKItten 有些东西我真的不明白。感谢您的帮助。

  userChange = () =>  {
    this.state.navigation.navigate('Login', {noAutoConnect : true});
  }

  Disconnect = () => {
    <TopNavigationAction icon={Quit} onPress={this.userChange}/>
  }
  
  render() {    
    return (
        <>
          <TopNavigation style={{ borderWidth: 1 }} title='Acceuil' alignment='center' accessoryLeft = {this.Disconnect}  />
            <View style = {style.lay}>
              <Button size = "giant" onPress = {this.navigateArticles} status = "danger"><Text>Accéder à mes Pdf</Text></Button>
            </View>
       </>
    );
  }
