Given a Go package defining an interface,
package testpkg
type I interface {
Fn()
}
I is mapped to an objective-c protocol and a proxy interface
that implements the routing of method calls from Go.
@protocol GoTestpkgI
-(void)Fn;
@end
Users implement a class conforming the generated protocol. For example,
@interface MyI <GoTestpkgI> {
}
@end
@implementation MyI {
}
- (void)Fn { .... }
@end
Gobind will also create a proxy interface to handle Go objects
implementing the interface and passed to Objective-C, but that will
be hidden from users.
@interface GoTestpkgI : NSObject <GoTestpkgI> {
...
-(void)Fn;
@end
The gobind code to generate the objective-c binding is in a separate CL.
