NSURLConnection making Asynch call a Synch and handle self signed certificate

Question

I am trying to make a Asynchronous Call , a Synchronous one. I know its not a better idea to do it. But, I do need such to code to handle Auth Challenge of Self Signed Certificate while Keeping the call still as Synchronous.

But, I am not sure whether it is a perfect way to make Asycnh call a Synch one.

-(NSData*) startConnection{
     NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];

   while(!isFinished && [[NSRunLoop currentLoop] runMode: NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]){
   }


   return responseAppData;
}


     - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
      //Code to handle Certificate
}


- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
       [responseAppData appendData:data];
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection{
         isFinished=YES;
}

I also thought of using the while Loop as below, so which one should be used?

   while(!isFinished ){
   }

a better way is to use block coding – Sunny Shah Jan 10 '14 at 05:20 — Sunny Shah, Jan 10 '14 at 05:20

Actually it's the opposite. If you want to handle these NSURLConnectionDelegate methods, you need to use asynchronous calls, NOT synchronous. Otherwise the delegates are never called.

My code works Asynchronous, responds to delegate and because of while condition it works as Synchronous code. – NNikN Jan 10 '14 at 05:42

 typedef void (^onDownload)(NSData *data);

@property (nonatomic,assign) onDownload block;


-(void) startConnectionwithBlock:(onDownload) pBlock;{
    self.block = [pBlock copy];
}
-(void) connectionDidFinishLoading:(NSURLConnection *)connection{
    block(self.data);
}

I do have method to work with block, but I need a synchronous method to handle self signed certifcate – NNikN Jan 10 '14 at 05:33
i think you can manage at didReceiveAuthenticationChallenge method for this? – Sunny Shah Jan 10 '14 at 05:37
