Nested Carousels makes every view lose quality #559

I used the nested carousel example and I noticed it was slowed than usual. Even though I tried to do the same. But my view is complex this time with uiimageview's, lots of labels, etc.

I'm using iOS 8.1 and Asset Catalogs.

But it somehow loses quality when using them on nested carousel. I'm posting an image with the nested carousel, and without it. Take a look:

Without nested carousels:

What could be causing this? And is there a way to fix it?

Are you just using linear transforms? If so, try using SwipeView instead of iCarousel as it doesn't exhibit this problem.

pbassut commented 9 years ago

@nicklockwood How is SwipeView implementation any different from iCarousel?

I'll try that anyway.

pbassut commented 9 years ago

Geez, it worked. Why? They have the same implementation.

Is it because iCarousel handles 3D and SwipeView doesn't?

nicklockwood commented 9 years ago

Yeah, it's because iCarousel uses 3D transforms and SwipeView uses 2D affine transforms.
