Navigation 离子2：清除离子选项卡导航历史记录

我有一个有5个标签的页面。我可以导航到一个选项卡，比如tab 1，然后如果我更改了该选项卡并返回到上一个选项卡，则会保留上一个选项卡（tab 1）导航堆栈

Sequence of events:

1) By default Tab 1 is showing with list of items 
2). I click on the item , go into the item detail and now back button is displayed 
3). Now I'm  moving to the second tab. 
4). finally moving to the first tab. Here again I see the item detail with the back button.

有人帮忙吗

没有你的代码很难说。原因可能是您没有在导航中将页面设置为rootPage，或者您可能在ion标题中使用了ion导航栏，而不是使用了ion工具栏
