Image Compression libraries for Objective-C

Question

OK, this is what I need :

Lossy and/or Lossless compression (all options are going to be considered, although Lossless compression will be favoured)
PNG and JPG files support
Cocoa-friendly code and easy integration

I've used OptiPNG in the past but I'm currently looking for an alternative.

Any suggestions?

@phix23 ImageIO only allows you to shrink an image, not to compress an image without changing its pixel dimensions. — Aaron Brager, Feb 06 '13 at 15:46

For lossy PNG compression use libimagequant (it will convert RGB/RGBA data to palette+alpha, which is 3 times smaller) combined with lodePNG (which supports palette+alpha format, unlike Cocoa's built-in methods).
