    <p>I want to integrate the <a href="http://www.aviary.com/ios-documentation" rel="nofollow">Aviary SDK</a> Objective-C library into Monotouch project. I use 'Monotouch Binding Project' template for this. I have built the DLL (Thanks smart people!) The project is compiled and run on the simulator.</p> <p>However I can NOT show the main Aviary view and the following code</p> <pre><code> this.afPhotoEditor = new AFPhotoEditorController(UIImage.FromFile("Images/site.jpg")); AFDelegate afDelegate = new AFDelegate(this); this.afPhotoEditor.Delegate = afDelegate; this.PresentModalViewController(this.afPhotoEditor, true); </code></pre> <p>returns the error:</p> <pre><code>Unhandled Exception: MonoTouch.Foundation.MonoTouchException: Objective-C exception thrown.

    1. COJust an idea, have you tried opening the bundle (I think it is "Show Contents", I'm on windows right now) and pulling out all the resources inside it? You could just add them all to your project in MonoDevelop.

    2. COThanks for advice. Yes bundle opens and I can get all files from it. But I tried many combination - No luck. I don't know what can cause this error. Maybe Aviary iOS can't be integrated with MonoTouch. Is it possible? OR MonoTouch can bind ANY ObjC Library?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
