AFJSONRPCClient *client = [AFJSONRPCClient clientWithEndpointURL:[NSURL URLWithString:url]];
[client invokeMethod:@"call" success:^(AFHTTPRequestOperation *operation, id responseObject){
        NSLog(@"response %@",responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *err){
        NSLog(@"errr  %@",[err description]);
    }];

i want wait until the response not getting.

Answer 1

You should use a delegate. Call it when you get a response.

Answer 2

Try to use completion handler block like this:

    - (void)doProcess_With_Comp:(void (^)(void))completion{
      dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        // Add Your process here
        AFJSONRPCClient *client = [AFJSONRPCClient clientWithEndpointURL:[NSURL URLWithString:url]];
        [client invokeMethod:@"call" success:^(AFHTTPRequestOperation *operation, id responseObject){
        NSLog(@"response %@",responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *err){
        NSLog(@"errr  %@",[err description]);
    }];
        dispatch_async(dispatch_get_main_queue(), ^{
          if (completion) {
            completion();
          }});
      });
    }

To call this:

[self doProcess_With_Comp:^{
  NSLog(@"Process Completed");}];

Hope it will help you.
