Objective-C Protocol Forward Declarations

Question

ObjectProperties.h

@protocol ObjectProperties 

@property (strong, nonatomic) NSString *name;
@property (strong, nonatomic) NSDate *         


        

Answer 1

Since you're declaring conformance to the protocol, you should #import the header containing the protocol.

This is the same as #importing a superclass, rather than forward declaring it:

@class Foo;

@interface Bar : Foo
// Will get error: attempting to use the forward class 'Foo' as superclass of 'Bar'
@end;
