Return to multi-level interface after Iospush

With the navigation controller push, pop can reverse back to the previous interface, but we need to return to the multi-level interface in the following two ways

Invoke API

-(Nsarray *) Poptoviewcontroller: (Uiviewcontroller *) Viewcontroller animated: (BOOL) animated;

1. Return by obtaining the subscript of the controller inside the navigation controller

[Self.navigationcontroller poptoviewcontroller:[self.navigationcontroller.viewcontrollers ObjectAtIndex:1] Animated:yes];

2. Traverse the controller inside the navigation controller to find the one that you want to return.

for(Uiviewcontroller *controllerinchSelf.navigationController.viewControllers) {
if([Controller Iskindofclass:[userinfocontrolclass]]) {
[Self.navigationcontroller Poptoviewcontroller:controller Animated:yes];
}
}
