ios - UIView transitionWithView animating property change: slide in from right? -


i have readonly uitextview, , i'm updating text. when new text appears, want animate follows: new text slides in right, old text slides offscreen toward left side.

is possible transitionwithview? if not, what's best way it? can make crossdissolve, that's not animation i'm looking for:

    [uiview transitionwithview:self.storytextview                   duration:0.5                    options:uiviewanimationoptiontransitioncrossdissolve                 animations:^{                     [self.storytextview settext:withstory.storytext];                 }                 completion:nil];

the reason insisting on right left animation because want user able trigger swiping toward left on uitextview.

catransition allow this, transition type of 'push' , subtype of 'from right'. it's straightforward use: 

catransition *transition = [catransition new]; transition.type = kcatransitionpush; transition.subtype = kcatransitionfromright;  // make view changes self.textview.text = newtext;  // add transition [self.textview.layer addanimation:transition forkey:@"transition"];

note this, while it's you've asked for, won't fit nicely gesture without tinkering - tie gesture you'd need set layer speed 0 , manually update progress of animation match gesture.
