Question

How can I store a UIImage in an NSDictionary?

Answer 1

It depends on what you want to do with your NSDictionary. While, yes, you can store a UIImage in NSDictionary, you may not be able to use said dictionary object in instances where you need it to conform to certain standards.

For example, you can use an NSDictionary as a value in standardUserDefaults, but only if every object in that dictionary is a property list object. UIImage is not a property list object. NSData is, so you can convert your UIImage to NSData with UIImageJPEGREpresentation, and store it that way, as mentioned above.
