Objective-C categories: Can I add a property for a method not in my category?

Question

I want to use a category to make a method on the original class available as a property as well.

Class A:

@interface ClassA
- (NSString*)foo;
@end

Here's the warning you're getting:

warning: property ‘foo’ requires method '-foo' to be defined - use @synthesize, @dynamic or provide a method implementation

To suppress this warning, have this in your implementation:

@dynamic foo;
