folderView_ = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"brownPaper.jpg"]];

[self.splitViewController.view addSubview:folderView_]; float duration = 1.5f; folderView_.hidden = NO;

if (folderView_.layer.anchorPoint.x != 0.0f) { folderView_.layer.anchorPoint = CGPointMake(0.0f, 0.5f); folderView_.center = CGPointMake(folderView_.center.x - folderView_.bounds.size.width/2.0f, folderView_.center.y); }

folderView_.frame.size.height);

[UIView animateWithDuration:duration delay:0.0f options:UIViewAnimationOptionCurveEaseInOut animations:^{ CATransform3D endTransform = CATransform3DMakeRotation(3.141f/2.0f, 0.0f, -1.0f, 0.0f); endTransform.m34 = 0.001f; folderView_.layer.transform = endTransform; } completion:^(BOOL finished) { if (finished) { folderView_.hidden = YES; [folderView_ removeFromSuperview]; [folderView_ release]; folderView_ = nil; } }];
