Is there a wrapper or some sort of built-in functionality available in RestKit
to load a UIImage
from an NSURL
asynchronously using callba
Not sure about a RestKit solution, but SDWebImage is a library that will let you easily load images asynchronously by adding a category to UIImageView, so all you have to write is this (for example):
[myImageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
placeholderImage:[UIImage imageNamed:@"placeholder.png"]];
