    <p>In general, <a href="https://stackoverflow.com/a/11655492/63225">@Monoman's <code>is</code> solution</a> is the right way to find instances of a particular class, even when you're looking for a CocoaTouch class from within a MonoTouch program.</p> <p>Sometimes, however, you'll discover that there's an internal CocoaTouch class that's not exposed in MonoTouch (or even in the iOS Platform headers). In such a case, you'll have to resort to <a href="https://stackoverflow.com/a/11657997/63225">tricks like @poupou is doing</a>.</p> <p>Unfortunately, his answers won't work here <em>either</em>. <code>view.GetType()</code> is returning the most-derived MonoTouch type that each <code>Subview</code> implements, and then <code>ToString()</code>, <code>Class.Name</code>, or even <code>@selector("description")</code> each operate on the wrong type and give an overly generic answer ("<code>UIView</code>" in this case).</p> <p>In order to make this work, you'll have to go one layer <em>deeper</em> under the covers than @poupou proposed.</p> <pre><code>// ** using MonoTouch.ObjCRuntime; ** private string GetClassName (IntPtr obj) { Selector description = new Selector ("description"); Selector cls = new Selector ("class"); IntPtr viewcls = Messaging.IntPtr_objc_msgSend (obj, cls.Handle); var name = NSString.FromHandle (Messaging.IntPtr_objc_msgSend (viewcls, description.Handle)); return name; } </code></pre> <p>Here's an alternative that's not a whole lot more fiddly (maybe even less?), but will work on any Objective-C class, not just those that respond to <code>NSObject</code>'s <code>description</code> message:</p> <pre><code>// ** using System.Runtime.InteropServices; ** [DllImport ("/usr/lib/libobjc.dylib")] private static extern IntPtr object_getClassName (IntPtr obj); private string GetClassName (IntPtr obj) { return Marshal.PtrToStringAuto(object_getClassName(obj)); } </code></pre> <p>It's actually surprising and a little bit sad that MonoTouch doesn't provide an import for <code>object_getClassName()</code> already.</p> <p>You would use either one of those like so:</p> <pre><code>foreach (UIView view in cell.Subviews) { if (GetClassName(view.Handle) == "UITableViewCellReorderControl") { } } </code></pre> <p><strong>Big fat disclaimer</strong>: Pretty much any time you're resorting to tricks like these, you're relying on CocoaTouch implementation details that Apple reserves the right to change. Rule of thumb: if you can do what you want with @Monoman's solution, you're <em>probably</em> safe. Otherwise, you're taking matters in to your own hands.</p>

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.
