UIImageView에 애니메이션을 추가 할 수없는 이유는 무엇입니까?

Question

음, UIImageView에 애니메이션을 추가하려하지만 항상 실패합니다. 왜? 여기에 코드입니다 : 사용

 //(…) 
     UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();  
     animationImage = [[UIImageView alloc]initWithImage:newImage]; 
     [self.view addSubview:animationImage]; 

     CATransition *animation = [CATransition animation]; 
     [animation setDelegate:self]; 
     [animation setDuration:0.35]; 
     [animation setTimingFunction:UIViewAnimationCurveEaseInOut]; 
     animation.type = @"pageCurl"; 
     animation.fillMode = kCAFillModeForwards; 
     animation.endProgress = 0.58; 
     [animation setRemovedOnCompletion:NO]; 
     [[animationImage layer] addAnimation:animation forKey:@"pageCurlAnimation"];

시도 :

[animation setTimingFunction:UIViewAnimationCurveEaseInOut];
