    <p>I made a popover class that I could call easily for basic popovers - you give it data and set the size and it should do the rest. </p> <p>This was working fine until iOS5, now the popover opens but with just the border, no white space or content at all.</p> <p>I've searched and searched, any ideas you could throw my way would be great.</p> <pre><code>@protocol BasicPickerDelegate - (void)basicPickerItemSelected:(NSMutableDictionary *)thisDic; @end @interface BasicPickerController : UITableViewController { // data IBOutlet NSMutableArray *theData; // stuff to set IBOutlet int myWidth; IBOutlet int myHeight; IBOutlet int myPopoverNum; // delegate id&lt;BasicPickerDelegate&gt; delegate; } @property (nonatomic, retain) IBOutlet NSMutableArray *theData; @property (nonatomic, assign) IBOutlet int myWidth; @property (nonatomic, assign) IBOutlet int myHeight; @property (nonatomic, assign) IBOutlet int myPopoverNum; @property (nonatomic, assign) id&lt;BasicPickerDelegate&gt; delegate; - (void)setSize; - (void)checkData; @end </code></pre> <p>Then the setSize function is viewDidLoad</p> <pre><code>- (void)setSize { if (!myWidth || !myHeight) { NSLog(@"WIDTH AND HEIGHT NOT SET, SETTING DEFAULTS"); myWidth = 100; myHeight = 100; } self.contentSizeForViewInPopover = CGSizeMake(myWidth, myHeight); } </code></pre> <p>Then I call it like this:</p> <pre><code>- (IBAction)showBasicPopover:(id)sender { // Show Basic Popover - can be reused if (basicPicker != nil) { self.basicPicker = nil; [self.basicPicker release]; } self.basicPicker = [[[BasicPickerController alloc] initWithStyle:UITableViewStylePlain] autorelease]; basicPicker.delegate = self; self.basicPickerPopover = [[[UIPopoverController alloc] initWithContentViewController:basicPicker] autorelease]; // Give popover the data it needs NSMutableDictionary *sizeDic = [self returnPopoverSize:[sender tag]]; self.basicPicker.myHeight = [[sizeDic objectForKey:@"height"] intValue]; self.basicPicker.myWidth = [[sizeDic objectForKey:@"width"] intValue]; self.basicPicker.myPopoverNum = [sender tag]; [basicPicker viewDidLoad]; self.basicPicker.theData = [self returnPopoverData:[sender tag]]; NSLog(@"giving popover dic (%d) with %d derps", [sender tag], [self.basicPicker.theData count]); // Set display settings and show popover [basicPicker viewWillAppear:YES]; CGRect popoverRect = [self.view convertRect:[sender frame] fromView:[sender superview]]; [self.basicPickerPopover presentPopoverFromRect:popoverRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; } </code></pre> <p>When I run it, the <code>WIDTH AND HEIGHT NOT SET, SETTIN DEFAULTS</code> dialogue comes up. For some reason it's not reading in the values it's given. Though with some fiddling, even if I can get it to read them in it don't think they are valid and overrides them.</p> <p><strong>edit:</strong> So basically:</p> <p>With setSize being called in viewDidLoad it doesn't know what the width and height is. So it sets the default.</p> <p>If setSize isn't called in viewDidLoad, it comes up with "no size" - ie it has popover border but no content in it at all.</p> <p>When setSize is called in viewWillAppear, viewDidAppear or anything like that (after viewDidLoad) it doesn't actually set the size of the popover.</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.
