    <p>I want to be able to have my app called from the email app when the users selects to open an attachment with a custom URL. It seems that IOS does recognize the registration but still does not call the application delegate to open the URL.</p> <p>I've registered my app to support a custom URL by adding this to info.plist;</p> <pre><code>&lt;key&gt;UTExportedTypeDeclarations&lt;/key&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;UTTypeConformsTo&lt;/key&gt; &lt;array&gt; &lt;string&gt;public.plain-text&lt;/string&gt; &lt;string&gt;public.text&lt;/string&gt; &lt;/array&gt; &lt;key&gt;UTTypeDescription&lt;/key&gt; &lt;string&gt;TecNotes Data File&lt;/string&gt; &lt;key&gt;UTTypeIdentifier&lt;/key&gt; &lt;string&gt;com.bringardner.textext&lt;/string&gt; &lt;key&gt;UTTypeTagSpecification&lt;/key&gt; &lt;dict&gt; &lt;key&gt;public.filename-extension&lt;/key&gt; &lt;string&gt;testext&lt;/string&gt; &lt;key&gt;public.mime-type&lt;/key&gt; &lt;string&gt;application/vnd.testext+xml&lt;/string&gt; &lt;/dict&gt; &lt;/dict&gt; &lt;/array&gt; </code></pre> <p>This is the code for the application delegate;</p> <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. if( launchOptions == nil) { NSLog(@"nil options"); } else { NSLog(@"Have options"); NSObject *obj = [launchOptions objectForKey:UIApplicationLaunchOptionsURLKey]; NSLog(@"url? %@",obj); } return YES; } -(BOOL) application:(UIApplication *)application handleOpenURL:(NSURL *)url { NSLog(@"handle %@",url); return YES; } - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { NSLog(@"open %@",url); return YES; } -(BOOL) application:(UIApplication *)application willFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSLog(@"willFinishLaunchingWithOptions "); return YES; } </code></pre> <p>Prior to adding the entries in info.plist I get the following message from the email app; <img src="https://i.stack.imgur.com/0QETU.png" alt="email error"> After adding entries to info.plist the email application opens a blank page but none of the application delegate methods are called. <img src="https://i.stack.imgur.com/Up9a8.png" alt="After image"> </p> <p>I've seen several similar questions but nothing I've attempted has solved the problem. </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.

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