ios - UIImageView CurlUp transition below a toolbar -

-

i working on implementation of slideshow control in ipad application.

manage different kinds of transitions between images, particularly uiviewanimationoptiontransitioncurlup.

viewcontroller's xib composed of 2 superposed uiimageviews, uitoolbar on 2 uiimageviews in order give user play/pause control.

here how looks : enter image description here

i today face problem when curlup transition occurs between 2 uiimageviews, see uitoolbar (which on 2 other views) animate : enter image description here

here how transition code looks :

if ([slideshow.images count] <= 1) {     return; } currentimageindex = ((currentimageindex + 1) >= [slideshow.images count]) ? 0 : currentimageindex + 1;  //imagestackview contains 2 uiimageviews bound iboutlets xib uiimageview *loadingimageview = [imageviewstack objectatindex:1]; loadingimageview.image = [slideshow.images objectatindex:currentimageindex]; uiimageview *currentimageview = [imageviewstack objectatindex:0];  [uiview transitionfromview:currentimageview                     toview:loadingimageview                   duration:slideshow.duration                    options:uiviewanimationoptiontransitioncurlup                 completion:^(bool finished) {                       uiimageview *swap = [imageviewstack objectatindex:0];                       [self.view bringsubviewtofront:toolbar];                       [imageviewstack removeobjectatindex:0];                       [imageviewstack addobject:swap];                       [self schedulenextanimation];         }];

please let me know if have idea !

thanks in advance !

i solved problem appending 2 uiimageviews in nib in parent uiview.
result, have view hierarchy following :

  • uiview
    • uiview (parent view uiimageviews)
      • uiimageview
      • uiimageview
    • uitoolbar
