JSInterfaceWebViewWrapper

JSInterfaceWebViewWrapper allow you to publish some class methods on a Javascript object in the JSInterfaceWebView Using dataSource you can provide some infos to the wrapper to configure it as well. Conforming to JSInterfaceWebViewDelegate protocol, you will have access to all UIWebViewDelegate protocol's methods and to another one that it is - (void)webView:(JSInterfaceWebView *)webView didReceiveCallToSelector:(NSString *)selectorName withParams:(NSDictionary *)params; This method will return the selector name (always without :, also if it accepts parameters, so, you have to check it out before call it) and a dictionary that it contains values for the key you passed before on - (NSArray *)webView:(JSInterfaceWebView *)webView publicParametersForSelector:(NSString *)selectorName;

Simple usage

JSInterfaceWebViewWrapper *webViewWrapper = [[JSInterfaceWebViewWrapper alloc] init];
webViewWrapper.delegate = self;
webViewWrapper.dataSource = self;
JSInterfaceWebView *webView = [webViewWrapper viewForWebView];
[self.view addSubview:webView];


- (void)webView:(UIWebView *)webView didReceiveCallToSelector:(NSString *)selectorName withParams:(NSDictionary *)params
{
  // In this example, if selectorName is "firstPublicMethod", dictionary will be
  // @{@"param1":VALUE,
  //   @"param2":VALUE};
  // If selectorName is "secondPublicMethod", dictionary is nil
  if (selectorName)
  {
    SEL selectorWithParams = NSSelectorFromString([NSString stringWithFormat:@"%@:", selectorName]);
    if ([self respondsToSelector:selectorWithParams])
    {
      [self performSelectorOnMainThread:selectorWithParams
                             withObject:params
                          waitUntilDone:YES];
    }
    else
    {
    [self performSelectorOnMainThread:NSSelectorFromString(selectorName)
                           withObject:nil
                        waitUntilDone:YES];
    }
  }
}
