title: ihasapp to get list of installed apps on ios giving an error
body: <p>i found the ihasapp framework on github: <a href="https://github.com/danielamitay/iHasApp" rel="nofollow">https://github.com/danielamitay/iHasApp</a></p>
  
  <p>i included the two files into the project..however it is giving an error:</p>
  
  <blockquote>
    <p>2013-03-14 11:21:35.848 apps[4338:2203] <strong>* Terminating app due to
    uncaught exception 'NSInvalidArgumentException', reason: '*</strong>
    -[NSConcreteData initWithContentsOfFile:options:error:]: nil file argument'</p>
  </blockquote>
  
  <p>here's the code that i am using in my viewcontroller:</p>
  
  <pre><code>#import "helloworldViewController.h"
  #import "iHasApp.h"
  
  @interface helloworldViewController ()
  
  @end
  
  @implementation helloworldViewController
  
  - (void)viewDidLoad
  {
      [super viewDidLoad];
      iHasApp *detectionObject = [iHasApp new];
      [detectionObject detectAppDictionariesWithIncremental:^(NSArray *appDictionaries) {
          NSLog(@"Incremental appDictionaries.count: %i", appDictionaries.count);
      } withSuccess:^(NSArray *appDictionaries) {
          NSLog(@"Successful appDictionaries.count: %i", appDictionaries.count);
      } withFailure:^(NSError *error) {
          NSLog(@"Failure: %@", error.localizedDescription);
      }];
  
      // Do any additional setup after loading the view, typically from a nib.
  }
  
  - (void)didReceiveMemoryWarning
  {
      [super didReceiveMemoryWarning];
      // Dispose of any resources that can be recreated.
  }
  
  @end
  </code></pre>
  
  <p>i am really new to ios development so the error might be very minor/silly. but any help would be great! </p>
