Test.h

/**
myProtocol.h
*/
@protocol MyProtocol <NSObject>
@property (nonatomic) BOOL myVariable;
@end
  
/**
MyClass.h
*/
@interface MyClass <MyProtocol>
@end

/**
MyClass.m
*/
@implementation MyClass
@synthesize myVariable;
@end

context nya lo hanya mau instance dari myVariable ya?

/**
MyClass.h
*/
@protocol MyProtocol
@interface MyClass
@Property(nonatomic, weak) id delegate;
@EnD

/**
MyClass.m
*/

@implementation
@synthesize delegate;
// do stuff with myVariable through the delegate
@EnD

hmm, kalau gw mw implementasi property di dalam delegate nya gmna pak?

kalau di swift dia bakal jadi setter getter

extension MyClass: MyProtocol {
  public var myVariable: Bool {
    get {
      // code here
    }
    set(myVariable) {
      // code here
    }
  }
}

kalau di objc, setelah di @synthesize, harus di init kah ?

ga perlu init lagi, akses dari delegate nya.

/**

@protocol MyProtocol <NSObject>
@property (nonatomic) BOOL myVariable;
@end

*/

/**
MyClass.m
*/

@implementation
@synthesis delegate
[delegate myVariable] = true;
@end
