• How to verify that post to website is coming from a specific purchased iPhone application?

  - by wgpubs

  I have an iPhone application that posts data to a web application ... and I want to only accept data posted from an iPhone application that was purchased from the iTunes store. Is there a way to do this? Is there something (or somethings) I can pass from the iPhone app to the web application that I can use to do such verification? Thanks much btw, using the asihttprequest library to handle requests/responses.

• "out of scope" error when iterating an NSMutableArray

  - by wgpubs

  Why am I getting an "out of scope" error whenever I try to access the "url" variable in this loop? for(NSString *url in self.winnerImageURLs) { [mediaItemString appendFormat:@"{\"type\":\"image\",\"src\":\"%@\",\"href\":\"%@\"},", url, url]; } The class of very item in the "self.winnerImageURLs" NSMutableArray comes back as NSCFString so I'm not sure what the dealio is here. Any ideas on what I'm doing wrong??? Thanks

• How to return objects in an NSArray at specified indexes?

  - by wgpubs

  Example: I have an NSArray with 40 objects. What is the most efficient way to return ONLY those objects with index equal to a number specified in another NSArray (e.g {0, 27, 36} for example)? Can a predicate be used here? Or is there a more simple and efficient approach?

• How to create a project template for Ruby on Rails projects?

  - by wgpubs

  When I build Rails applications I find myself doing the same things over and over again. This includes adding the same gems/plugins, configuration info and custom initializers, rake tasks etc... etc.... This can't be a good thing. So, is there a way to package all this repetitive code into some sort of project template ... so that I can do a "rails myapp" and have everything good to go from there? Btw, running 2.3.5 if that matters :) thanks

• Problem implementing a UITableView that allows for multiple row selections

  - by wgpubs

  This - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; int cardNumber = indexPath.row + 1; if (cell.accessoryType == UITableViewCellAccessoryNone) { cell.accessoryType = UITableViewCellAccessoryCheckmark; if (![self.winningNumbers containsObject:[NSNumber numberWithInt:cardNumber]]) [self.winningNumbers addObject:[NSNumber numberWithInt:cardNumber]]; } else { cell.accessoryType = UITableViewCellAccessoryNone; if ([self.winningNumbers containsObject:[NSNumber numberWithInt:cardNumber]]) [self.winningNumbers removeObject:[NSNumber numberWithInt:cardNumber]]; } [tableView deselectRowAtIndexPath:indexPath animated:YES]; } ... modifies the "accessoryType" of every 6th cell INSTEAD of just the selected row. What am I missing? Thanks

• Core Data: Mass updates possible?

  - by wgpubs

  Is it possible to do mass updates on a given entity in Core Data? Given an Person entity for example, can I do something like this: Person.update(@"set displayOrder = displayOrder + 1 where displayOrder > 5") Or is my only option to fetch all the entities needed and then loop through and update them individually??? Thanks

• Speech recognition webservice that scores the accuracy of one audio clips vs. another?

  - by wgpubs

  Does such a thing exist? Building a Rails based web application where users can upload an audio file of them speaking that then needs to be compared to another audio file for the purposes of determining how similar to voices are. Ideally I'd like to simply get a response that gives me a score of how similar they are in terms of percentage (e.g. 75% similar etc...). Anyone have any ideas? Thanks

• Is there a Ruby on Rails framework like equivalent for .NET development?

  - by wgpubs

  Answers like ASP.NET MVC or Entity Framework really aren't acceptable as they address just one aspect of the problem domain. I'm looking for a framework ... a REAL framework that gives me the same features out of the box that Rails does. As such it should include at minimum: MVC for presentation ORM Ability to provide simple configuration for whatever environment (dev, QA, Production, etc...) Migration like functionality Ability to generate code in all layers (similar to scaffolding like behavior, etc...) Project template so as to create similar functionality as the "rails my_app" command. Thanks.
