objective c - View lose cornerRadius with Animation of UIViewAnimationOptionTransitionFlipFromLeft on iOS 8 -

in code, have set:

imageview.layer.maskstobounds = yes; imageview.layer.cornerradius = imageview.frame.size.width/2; 

and run in animation block:

[uiview transitionwithview:imageview                       duration:1.0                        options:uiviewanimationoptiontransitionflipfromleft                     animations:nil                     completion:^(bool finished) {                         imageview.hidden = yes;                     }]; 

but when running on ios 8, imageview normal, means there no cornerradius imageview.

could tell me why?

you need slash corners of uiimage not uiimageview using calayer using below code.

// load image on imageview programmatically  uiimage *image = [uiimage imagenamed:@"yourimage.png"];  // assign changes reflected using method before load image imageview image = [self makeroundedimage:image radius:_imageview.frame.size.width/2]; _imageview.image = image; 

---

// method create round image -(uiimage *)makeroundedimage:(uiimage *) image radius: (float) radius{      calayer *imagelayer = [calayer layer];     imagelayer.frame = cgrectmake(0, 0, image.size.width, image.size.height);     imagelayer.contents = (id) image.cgimage;      imagelayer.maskstobounds = yes;     imagelayer.cornerradius = radius;      uigraphicsbeginimagecontext(image.size);     [imagelayer renderincontext:uigraphicsgetcurrentcontext()];     uiimage *roundedimage = uigraphicsgetimagefromcurrentimagecontext();     uigraphicsendimagecontext();      return roundedimage; }  

now can apply animation simply.
