在主页选项卡中，单击“科学事实”按钮并转到下一页，隐藏选项卡栏，效果很好。 接下来，单击“更多事实”按钮转到下一页，但不会隐藏选项卡栏。 我不知道为什么，$ rootScope.hideTabs是真的，但标签栏仍在这里。
感谢。

删除指令 ＆＃34; hideTabs＆＃34;
.directive('hideTabs', function($rootScope) {
......
});
并添加以下简单代码，工作正常。
.run(function($rootScope, $location, $ionicPlatform) {
$ionicPlatform.ready(function() {
$rootScope.$on("$locationChangeStart", function(event, next, current) {
if ($location.url() == '/tab/facts2' || $location.url() == '/tab/facts') {
$rootScope.hideTabs = true;
}else{
$rootScope.hideTabs = false;
}
});
});
})
