title: Try-Catch Error Objective C
body: <p>I am trying to get Captions from a given instagram picture, however if there is no caption the app throws an exception and crashes. How would I implement <code>@try</code> and <code>@catch</code> to do this. Here is what i have so far:</p>
  
  <pre><code>@try {
      RNBlurModalView *modal = [[RNBlurModalView alloc] initWithViewController:self title:[NSString stringWithFormat:@"%@",entry[@"user"][@"full_name"]] message:[NSString stringWithFormat:@"%@",text[@"caption"][@"text"]]];
      [modal show];
  }
  @catch (NSException *exception) {
      NSLog(@"Exception:%@",exception);
  }
  @finally {
    //Display Alternative
  }
  </code></pre>
