iPhone UIImageView и CABasicAnimation

Question

Я делаю простой поворот карты, который работает нормально, но когда я добавляю пользовательский фон изображения, после вращения карты изображение обрезается наполовину.Есть идеи?

float scaleValue = M_PI/2;

CABasicAnimation *yRotation;
yRotation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];
yRotation.fromValue = [NSNumber numberWithFloat:0.0];
yRotation.toValue = [NSNumber numberWithFloat:scaleValue];
yRotation.duration = .5;

CABasicAnimation *yRotation2;
yRotation2 = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];
yRotation2.fromValue = [NSNumber numberWithFloat:scaleValue];
yRotation2.toValue = [NSNumber numberWithFloat:0.0];
yRotation2.duration = .5;
yRotation2.cumulative = YES;
yRotation2.beginTime = .5;

CAAnimationGroup *groupAnim = [CAAnimationGroup animation];
groupAnim.removedOnCompletion = NO;
groupAnim.duration = 1;
groupAnim.fillMode = kCAFillModeForwards;
groupAnim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
groupAnim.animations = [NSArray arrayWithObjects:yRotation, yRotation2, nil];

[[image objectAtIndex:num] addAnimation:groupAnim forKey:@"animateCard"];
[self.view bringSubviewToFront:[image objectAtIndex:num]];

однажды попробуй, он будет отлично работать ... без рубки
