Load image asynchronously in IOS

Hi, I’m trying to asynchronously load an image from a url in IOS. I tried adding the ofxThreadedImageLoader class, but I can’t get it to work. I’m not even sure if it is compatible with IOS. Has anyone managed to use the ofxThreadedImageLoader class with IOS or should I use some other method?

When I add the ofxThreadedImageLoader files to my Xcode project it indicates an error at line 7 ofAddListener(ofEvents().update, this, &ofxThreadedImageLoader::update);
"Type ‘ofCoreEvents’ does not provide a call operator

Any thoughts?
Am I missing something obvious?
best,
Richard

I have same trouble.
When I try run simple app, compiller write that have error in this place:
ofxThreadedImageLoader.cpp

entry.image->setUseTexture(false); Thread 1: EXC_BAD_ACCES (code=1, address = 0x118)
