Using callback from Objective-C to Cocoascript

callback_objc2cocoa.md

Re-build cocoa framework

• Clone source code from: https://github.com/ccgus/CocoaScript
• Make MOJavascriptObject.h as public headers in Build Phases
• Build project and we will get CocoaScript.framework
• Copy CocoaScript.framework to your Xcode project

Define the objective-c methods with callback

API.h

#import <Foundation/Foundation.h>
#import <CocoaScript/MOJavaScriptObject.h>
#import <CocoaScript/COScript.h>

@interface Api : NSObject
- (void) login:(NSDictionary*)params onComplete:(MOJavaScriptObject*)onComplete;
@end

API.m

- (void) login:(NSDictionary*) params onComplete:(MOJavaScriptObject*)onComplete {
  // handle your logic
  
  // call the callback
   COScript *script = [[COScript alloc] init];
  [script callJSFunction:[onComplete JSObject] withArgumentsInArray:@[@true, @{@"name": @"Sam"}]];
}

Using in .cocoascript

var api = API.alloc().init();
api.login({
  username: 'sam',
  password: '123456'
}, function (success, user) {
  log(success);
  log(user);
});
