tabnavigator

问题 I am in doubt about mixing navigator and tabbar. Explaining: the main page (Main page1) consists of two child pages (tab1 and tab2) that are accessed by tabbar, while the other pages (page2 and 3) are accessed through the navigator. The tab1 page is the first one actived. Layout: the tab1 and tab2 pages have the same toolbar (on the top). The page2 and page3 has different toolbar with back-button and another button to redirect to mainpage tab1. My code is this, but i don`t know if it is

问题 I am trying to have a DrawerNavigator when user taps on the last tab(for example 'More') in TabNavigator. How is this possible to achieve it without having a screen for that tab and then calling the DrawerNavigator in componentWillMount. componentWillMount() { this.props.navigation.navigate("DrawerOpen") } It is kind of a hack which is not proper solution I think(This way 'More' screen is loaded), there has to be a better solution for that. 回答1: This is also a bit of hack but I think its the

问题 I have an application whereby I am creating tabs in a TabNavigator dynamically. As you can see as per my codes I am basically having 5 tabs with specific names.

What I want to do is to load

问题 I have a strange problem where I am trying to build tabs in a tab navigator with a combination of mxml and AS-3.

Any ideas what's happened- and how to handle this? http://pastebin.com
