Grouped Listview overlapping with bottom navigation bar for iOS?

I have a bottom navigation bar (Tabbed Page) with four 4 tabs, the 4th tab has navigation page which will navigate to other pages.
The 4th tab is having grouped listview which will navigate to other pages and again if I click on the 4th tab from child pages of 4th Tab will navigate to the Top page (which is grouped list page) making the problem. If I click other Tabs and come back to 4th Tab is not creating the problem.
If I coming back to the 4th tab (grouped listview page) from child page of list page the last 2 items are not able to click. Here my assumption is the bottom tab bar is overlapping with listview while coming back from the child page.
But if I come back from the main tabs it is working fine. And this is occurring for iOS only Android is working fine.
Can anybody help me out to fix this issue?
