iOS custom Modify navigation Back button

iOS development, navigation's return button is English "back", want to change into Chinese "return" or custom text; it was a simple thing to toss for half an hour. It turned out to be confused by the way Leftbarbuttonitem and Rightbarbuttonitem were set up.
We set Leftbarbuttonitem and Rightbarbuttonitem in the current page, while Backbarbuttonitem is on the parent page, so we need to call

 [ Self.Navigationcontrollerpushviewcontroller:p HotocontrollerAnimated:YES];

The code is as follows:

   Self.Navigationitem.Backbarbuttonitem=[[Uibarbuttonitemalloc] Initwithtitle:@ "return"Style:Uibarbuttonitemstyleborderedtarget:NilAction:Nil];

    [ Self.Navigationcontrollerpushviewcontroller:p HotocontrollerAnimated:YES];

Give it a try!
