JS code:

share({
text:"test text",
url:"http://codingnext.com",
callback:function(){
    console.log('test func');
  }
});

Objective-C code:

- (void)share:(NSDictionary *)params {
    NSString *text = params[@"text"];
    NSString *url = params[@"url"];
    JSValue *callBack = params[@"callback"];
    [callBack callWithArguments:nil];
  }

I got the right text and url ,but the wrong callback.I want to know why and how to fix it .

  • Yes,but my problem is different.The params and callback are mixed so the Obj-C code can't figure out which should turn to JSValue. And when I use params[@"callback"],the application exits. Commented Mar 12, 2018 at 15:21
