    <p>I have an app where I display the photo chooser (UIImagePickerController) but after the user dismisses it only single touches are working. And I think I know the root of the issue, but I don't know how to solve it... Before I show the modal dialog the stack during a touch is as follows:</p> <pre> ... #3 0x00074de0 in -[EAGLView touchesBegan:withEvent:] at EAGLView.m:289 #4 0x30910f33 in -[UIWindow _sendTouchesForEvent:] ... </pre> <p>But after showing and then removing the modal dialog the stack has these two mysterious forwardMethod2 calls:</p> <pre> ... #3 0x00074de0 in -[EAGLView touchesBegan:withEvent:] at EAGLView.m:289 #4 0x3098dc95 in forwardMethod2 #5 0x3098dc95 in forwardMethod2 #6 0x30910f33 in -[UIWindow _sendTouchesForEvent:] ... </pre> <p>Here is the code I use to display and remove the UIImagePickerController: Notes: 1. pickerViewController is a member of this class that extends UIViewController) 2. Director is from Cocos2D and contains only a single view attached directly in the root window called openGLView, which is why I made a UIViewController to house my image picker.</p> <pre><code>-(void)choosePhoto: (id)sender{ UIImagePickerController *imagePickerController = pickerViewController.imagePickerController; imagePickerController.delegate = self; imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; imagePickerController.allowsImageEditing = YES; UIView *theView = [[Director sharedDirector] openGLView]; UIView *pickerViewControllerView = pickerViewController.view; [theView addSubview:pickerViewControllerView]; [pickerViewController presentModalViewController:imagePickerController animated:YES]; } </code></pre> <p>And the code to dismiss the dialog:</p> <pre><code>- (void)imagePickerControllerDidCancel:(UIImagePickerController *)imagePickerController { // Dismiss the image selection [pickerViewController dismissModalViewControllerAnimated:YES]; [pickerViewController.view removeFromSuperview]; // HERE... IS THERE MORE WORK TO BE DONE TO COMPLETELY REMOVE THE PICKER VIEW???? } </code></pre> <p>There must be something I'm missing in cleaning up the picker view... Help is greatly appreciated :)</p>

    1. COare you sure you need to do the addSubView? I don't think that's necessary, and I'd try removing it to see if it's causing the strange behavior.

    2. COYeah, taking that part out never shows the dialog. Because "self" isn't a viewController and otherwise my app doesn't use ViewControllers for anything, I have to make one and add it' view to my existing view.

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.
