    <p>I'm trying to create programmatically a uiPickerView and add it to a view without using interface builder. Don't get me wrong, I like IB but the reason why I want to do it this way is because i'm trying to build an object that I can quickly plug in to produce popup menus using UIPopoverViewController and a variety of different subViews (such as uiPickerView) as the menu in the popup. I've already made this work by building the menu in IB and initializing the popup with its ViewController so I know how this works for the most part.</p> <p>I've entered the relevant code below and this is the two errors I get when I run it: - "Could not find mapped image UIPickerViewFrameRight-162-Popover.png" - "Could not find mapped image UIPickerViewFrameLeft-162-Popover.png"</p> <p>I don't know what these images are but I'm assuming they are the png's of the picker view.</p> <pre><code>menu = [[UIPickerView alloc]initWithFrame:CGRectMake(0,100,162,162)]; menu.delegate = self; menu.dataSource = self; [menu reloadAllComponents]; [menu selectRow:0 inComponent:0 animated:YES]; //Add the picker to the view [customViewController.view addSubview:menu]; popView = [[UIPopoverController alloc] initWithContentViewController:customViewController] ; [popView setDelegate:self]; CGRect pos = [rootView frame]; [popView presentPopoverFromRect:CGRectMake(pos.origin.x,pos.origin.y,0,pos.size.height) inView:displayView permittedArrowDirections:arrowDir animated:YES]; </code></pre> <p>Now this Code will crash the program unless you remove the line where I try to add the picker to the view, at which point I just get the blank popover. So I know that it is the picker that is causing this issue however I don't know how to fix it. I've been searching all day but every tutorial online on uipickers all include using IB. My guess is that this is a really stupid error like missing an import or something but if anyone can tell me what I'm doing wrong it would be greatly appreciated.</p> <p>Also note that I followed the tutorials on how to set up the dataSource and delegate methods for the UIPickerView and I'm pretty sure they are fine however if you want to verify here you are: Thanks again.</p> <pre><code>#import "PopUpMenuViewController.h" @implementation PopUpMenuViewController @synthesize menuType; @synthesize data; @synthesize popView; @synthesize menu; @synthesize customViewController; #pragma mark - #pragma mark UIPOPOVERCONTROLLER DELEGATE METHODS #pragma mark - - (BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController{ //Delegate this too the User of this class return TRUE; } - (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController{ //Delegate this too the User of this class } #pragma mark - #pragma mark CUSTOM POPOVERVIEWCONTROLLER METHODS #pragma mark - -(void) initWithMenuType:(int)type{ menuType = type; } -(id) initWithMenuType:(int)type andData:(NSMutableArray *)dataSet fromViewItem:(id)sender withMainView:(UIView *)mView{ [super init]; menuType = type; data = dataSet; rootView = sender; displayView = mView; arrowDir = UIPopoverArrowDirectionUp; customViewController = [[UIViewController alloc] initWithNibName:@"PopUpMenu" bundle:nil]; return self; } -(void) setPopUpArrowDirection:(UIPopoverArrowDirection) arrow{ arrowDir = arrow; } -(void) showPopUp{ //UIPicker Menu if (menuType==1) { //UIPicker Setup menu = [[UIPickerView alloc]initWithFrame:CGRectMake(0,100,162,162)]; menu.delegate = self; menu.dataSource = self; [menu reloadAllComponents]; [menu selectRow:0 inComponent:0 animated:YES]; //Add the picker to the view [customViewController.view addSubview:menu]; popView = [[UIPopoverController alloc] initWithContentViewController:customViewController] ; [popView setDelegate:self]; CGRect pos = [rootView frame]; [popView presentPopoverFromRect:CGRectMake(pos.origin.x,pos.origin.y,0,pos.size.height) inView:displayView permittedArrowDirections:arrowDir animated:YES]; //[popView setPopoverContentSize:CGSizeMake(menu.frame.size.width+5,menu.frame.size.height+5)]; } } #pragma mark - #pragma mark VIEW CONTROLLER DELEGATE METHODS #pragma mark - // The designated initializer.

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.
