ios - Resize subviews on animated frame change (autoresizing mask)? -

i know works if change view's frame via changing of layer's transform (in case takes view subviews , works if single image). not enough me use because:

1. it hard calculate appropriate position;
2. i use hmlauncherview has logic based on frames not transforms.

i tried lot of ways described here seems autolayout because none of them works. depending on type of autoresizing mask elements jump destination position , of them not affected @ or affected via strange ways.

how solve such issue? there ways solve via autoresizing mask?

animation code (the same result setting of center/bounds):

[uiview animatewithduration:0.3 animations:^{                  lastlaunchericon.layer.transform = catransform3didentity;                 cgrect r = self.bounds;                 r.origin.y = max(0, min(self.scrollview.contentoffset.y, self.scrollview.contentsize.height - self.bounds.size.height));                 launchericon.frame = r;             } completion:^(bool finished) {                  ...             }]; 

the code of layoutsubviews seems because have tried subclass uilabel jumps animation destination position. investigation showed frame of label set when set view's frame/bounds only. in other cases label's setcenter, setframe , setbounds called when call them directly.

this question similar suggested solution doesn't work case. found out had broken view transformation doesn't appear on ios 7.1 (maybe 7.x) works on 8.3.
