Question

I am building an iOS app using Rubymotion. I need to cache remote images located in a table view. I am trying to use the Cocoapod called “JMImageCache” found here: https://github.com/jakemarsh/JMImageCache.

I cannot figure out how to use it and how to convert the objective-c code to Ruby.

This is the Objective-C code:

UIImage *image = [[JMImageCache sharedCache] imageForURL:@"http://dundermifflin.com/i/MichaelScott.png" delegate:self];

I tried to convert it like this but it is wrong:

image = JMImageCache.sharedCache(imageForURL:post.image_medium, delegate:self)

Answer 1

Try this:

image = JMImageCache.sharedCache.imageForURL(post.image_medium, delegate:self)

imageForURL is a method on sharedCache, sharedCache returns an object, but you were sending it arguments like it was a method.
