Caching or saving an image from web Objective C - objective-c

Question

I currently have an app that loads an image from the web like this
[self.userImage setImageWithURL:IMAGEURL placeholderImage:[UIImage imageNamed:#"userPhoto.png"]];
and it works perfectly. I'm still wondering if I can somehow save or cache the image so it shows up quicker when the user opens the app again.
Any help is greatly appreciated.
EDIT:
After importing SDWebImage to my class and upon compiling I get this error

Answer 1

Sure, you can save the file to disk yourself and check if it exists before you try to load it (all based on URL matching). There are also libraries that will do this kind of stuff for you like SDWebImage / HJCache.

Answer 2

You can try AsyncImageView. It has inbuilt caching support.

Answer 3

try this:
you can try with EGOImageLoading
for image caching support.
