AtSugarMixin

AtSugarMixin extends AtSugar to easily uses Mixins. Mixin functionality is provided by ObjectiveMixin.

Installation

AtSugarMixin is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "AtSugarMixin"

Then include the header:

#import <AtSugarMixin/ASMixin.h>

First, declare a protocol for behavior implemented by a mixin. AtSugarMixin even allows you to mixin properties!

@protocol MyMixinProtocol <NSObject>

@property (strong, nonatomic) NSString* aStringProperty;
@property (strong, nonatomic) NSArray* anArrayProperty;

- (void)doSomething;

@end

You then create a class that will provide the mixin implementation. This class conforms to your mixin protocol.

#define MyMixinSynthesizeProperties aStringProperty, anArrayProperty


@interface MyMixin : NSObject <MYMixinProtocol>

@end

We need to define MyMixinSynthesizeProperties so that that AtSugarMixin will synthesize the properties from the protocol.

@implementation MyMixin

@synthesize_from_mixin (MyMixin)

- (void)doSomething
{
    // implementation
}

@end

Now we can mixin our MyMixin behavior to any class we want.

@interface MyObject : NSObject <MyMixinProtocol>

@end

@implementation MyObject

@synthesize_from_mixin (MyMixin)

@end

Now MyObject has 2 mixed in properties: aStringProperty and anArrayProperty. It also has a mixed in method: -doSomething.
