解决快速点击多次跳转
当我们快速点击跳转时，会开启多个重复的界面，如何解决呢。其实在官方Git中也有提示，解决这个问题需要修改react-navigation源码：
找到scr文件夹中的addNavigationHelpers.js文件,替换为如下文本即可：
export default function<S: *>(navigation: NavigationProp<S, NavigationAction>) {
  // 添加点击判断
  let debounce = true;
  return {
      ...navigation,
      goBack: (key?: ?string): boolean =>
          navigation.dispatch(
              NavigationActions.back({
                  key: key === undefined ? navigation.state.key : key,
              }),
          ),
      navigate: (routeName: string,
                 params?: NavigationParams,
                 action?: NavigationAction,): boolean => {
          if (debounce) {
              debounce = false;
              navigation.dispatch(
                  NavigationActions.navigate({
                      routeName,
                      params,
                      action,
                  }),
              );
              setTimeout(
                  () => {
                      debounce = true;
                  },
              500,
              );
              return true;
          }
          return false;
      },
    /**
     * For updating current route params. For example the nav bar title and
     * buttons are based on the route params.
     * This means `setParams` can be used to update nav bar for example.
     */
    setParams: (params: NavigationParams): boolean =>
      navigation.dispatch(
        NavigationActions.setParams({
          params,
          key: navigation.state.key,
        }),
      ),
  };
}
