first have present modal view controller inside navigation controller:

myviewcontroller *vc = [[myviewcontroller alloc] initwithnibname:@"mynib" bundle:nil]; uinavigationcontroller *nc = [[uinavigationcontroller alloc] initwithrootviewcontroller:vc];  [self presentmodalviewcontroller:nc animated:yes];  [vc release]; [nc release];

then inside myviewcontroller can do:

otherviewcontroller *vc = [[otherviewcontroller alloc] initwithnibname:@"myothernib" bundle:nil]; [self.navigationcontroller pushviewcontroller:vc animated:yes]; [vc release];

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
