    <p>really, really odd error</p> <p>I have an app that was working fine in iOS5/.1, now I'm having a few transition problems with iOS6 but this one is confusing. </p> <p>I have some code that launches a mail composer, and since iOS 6 it causes a crash with this error:</p> <p><strong>* Assertion failure in -[UICGColor encodeWithCoder:], /SourceCache/UIKit/UIKit-2372/UIColor.m:1191 2012-09-26 02:14:38.044 MyCQs Medical[2126:1b03] *</strong> Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Only support RGBA or the White color space, this method is a hack.'</p> <p>Any suggestions? Through trial and error commenting out various lines it seems to be the alloc/init line that causes the error, though when all the lines are uncommented, all of the NSLogs are executed, including "present" which indicates that everything that should be called, has been. the app crashes before the mailcomposer is presented on screen, I'd really appreciate any advice here</p> <pre><code> if (indexPath.row == 3) { if([MFMailComposeViewController canSendMail]){ mailComposer = [[MFMailComposeViewController alloc]init]; NSLog(@"Alloc, init"); mailComposer.mailComposeDelegate = self; NSLog(@"Set delegate"); NSArray *toArray = [[NSArray alloc]initWithObjects:@"john@doe.com", nil]; NSLog(@"To array"); [mailComposer setToRecipients:toArray]; NSLog(@"To recipients"); [mailComposer setSubject:@"Message from a MyCQs user!"]; NSLog(@"Subject"); NSLog(@"About to present mail composer"); [[mailComposer navigationBar] setTintColor:[UIColor blackColor]]; [self presentModalViewController:mailComposer animated:YES]; NSLog(@"Present"); } } </code></pre>

    1. COHave you tried setting the tint coor of your mailComposer's navigationBar like this? mailComposer.navigationBar.tintColor = [UIColor colorWithRed:1.0 Green:1.0 Blue:1.0 Alpha:1.0];?

    2. COhi Gerald cheers for the reply - yes I have tried that, as I suspected it might be the fact that I've taken advantage of iOS 6's 'custom status bar tint color' (long shot I know). My app has custom graphics for navigation bars etc....not sure if that has anything to do with it

    3. COhe assertion failure details lead me to believe that, perhaps unawares, you are attempting to archive a color that does not conform to the NSCoding protocol. Hopefully that gives you some kind of hint. I hae to run at the moment but I'll look in later and see whether you've resolved this issue and whether I can try to help.

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.
