How to handle Objective-C protocols that contain properties?

Question

I\'ve seen usage of Objective-C protocols get used in a fashion such as the following:

@protocol MyProtocol 

@required

@property (readonly)         


        

Answer 1

Here's an example of mine that works perfectly, the protocol definition first of all:

@class ExampleClass;

@protocol ExampleProtocol

@required

// Properties
@property (nonatomic, retain) ExampleClass *item;

@end

Below is a working example of a class supporting this protocol:

#import 
#import "Protocols.h"

@class ExampleClass;

@interface MyObject : NSObject  {

    // Property backing store
    ExampleClass        *item;

}


@implementation MyObject

// Synthesize properties
@synthesize item;

@end
