    <p>I trying to write rhodes native extension extension for opening <em>iOS MailComposer</em>. Now code "works", but <em>MFMailComposeViewController</em> not displaying and xcode shows warning:</p> <pre><code>Attempt to present &lt;MFMailComposeViewController: 0x12b60840&gt; on &lt;Iosmailto: 0xc1898d0&gt; whose view is not in the window hierarchy! </code></pre> <p>I read that UIViewControllers must be in hierarchy, but i can't provide this from Rhodes ruby code or clear-C extension wrapper. Now i'm trying to present my <em>UIViewController</em> with <em>MFMailComposeController</em> from <em>[UIApplication sharedApplication].keyWindow.rootViewController</em> but mail composer not show yet.</p> <p>interface from iosmailto.h:</p> <pre><code>@interface Iosmailto : UIViewController&lt;MFMailComposeViewControllerDelegate&gt; { } @property(nonatomic, assign) id delegate; //-(IBAction)send_mail:(id)sender; @end </code></pre> <p>implementation from iosmailto.m:</p> <pre><code>@implementation Iosmailto - (void)viewDidLoad { [super viewDidLoad]; [self send_mail]; } - (void)send_mail { if ([MFMailComposeViewController canSendMail]) { MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init]; composer.mailComposeDelegate = self; [composer setSubject:[NSString stringWithUTF8String:subj]]; NSArray *recipients_array = [NSArray arrayWithObject:[NSString stringWithUTF8String:recipients]]; [composer setToRecipients:recipients_array]; NSString *composerBody = [NSString stringWithUTF8String:message]; [composer setMessageBody:composerBody isHTML:NO]; [composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; [self presentModalViewController:composer animated:YES]; [composer release]; } else { NSLog(@"Device is unable to send email in its current state."); } } /* some unnecessary for this question methods */ @end </code></pre> <p>And C function defined in iosmailto.m thats called from Rhodes:</p> <pre><code>// find root vc UIViewController *topController = [UIApplication sharedApplication].keyWindow.rootViewController; // find topmost vc while (topController.presentedViewController) { topController = topController.presentedViewController; } iosmailer = [[Iosmailto alloc] init]; iosmailer.delegate = topController; [topController presentViewController:iosmailer animated:YES completion:nil]; </code></pre> <p>This app is not for AppStore. Hacks is welcome if needed.</p> <p><strong>Update</strong> init for Iosmailto:</p> <pre><code>- (id)init { self = [super initWithNibName:nil bundle:nil]; return self; } </code></pre> <p><strong>Update 2</strong> The short version of this code (without UIViewController wrapper) was my starting point. That's don't work too. And this have the same warning and one more:</p> <pre><code>UIViewController *topController = [UIApplication sharedApplication].keyWindow.rootViewController; while (topController.presentedViewController) { topController = topController.presentedViewController; } if ([MFMailComposeViewController canSendMail]) { MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init]; composer.mailComposeDelegate = (id&lt;MFMailComposeViewControllerDelegate&gt;)topController ; [composer setSubject:[NSString stringWithUTF8String:subj]]; NSArray *recipients_array = [NSArray arrayWithObject:[NSString stringWithUTF8String:recipients]]; [composer setToRecipients:recipients_array]; NSString *composerBody = [NSString stringWithUTF8String:message]; [composer setMessageBody:composerBody isHTML:NO]; [composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; [topController presentModalViewController:composer animated:YES]; [composer release]; } else { } </code></pre>

    1. COWhat's your init method look like for Iosmailto? You'll want to be sure that you either call initWithNib: (defined in UIViewController, inherited by your subclass) or make sure your custom init method calls [super initWithNib:]

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.
