Flip is slow on iPad 3.

This is more of a comment then an actual bug but because of the retina display, "[self.layer renderInContext:UIGraphicsGetCurrentContext()];" is very slow causing a bad user experience.
We are wondering if there would be a way around it besides pre-loading/caching.
Thanks in advance for your feedback.

try to replace it for this:

if ([self respondsToSelector:@selector(drawViewHierarchyInRect:afterScreenUpdates:)]) [self drawViewHierarchyInRect:self.bounds afterScreenUpdates:YES]; else [self.layer renderInContext:UIGraphicsGetCurrentContext()];
