Error: Blank body causes crash

[jefflinwood]

If you don't add anything in the body field in the Drupal node, the app will crash with an exception on this line:

    [self.bodyWebView loadHTMLString:[self.tip objectForKey:@"body"] baseURL:nil];

Of TnTViewController.m

In my website I have all three fields mandatory for Tip. But it may be chance that for any other reason tip object or tip "body" object can be nil or "" if kept empty that In have put UIalertView to inform user about the failure.

You can do that, or you can just put in a check to see if the body isEqualTo:[NSNull null] and then put in some default text like "No content found for: "

When body content is left blank, retrieved JSON has string in it So I have matched bodyHTML against that.
