Objective C Generics

Objective C Generics is an implementation of Objective C on github that is similar to C ++, Java, and C.

The usage is as follows:

SetObjectiveCGenerics.hDrag into your project. when defining a new class, useGENERICSABLEMacro description.

#import "ObjectiveCGenerics.h"GENERICSABLE(MyClass)@interface MyClass : NSObject<MyClass>@property (nonatomic, strong) NSString* name;@end

Then you will be able to use the paradigm like C ++, Java, and C.

ObjectiveCGenerics.hThe source code is as follows:
