I'm trying to draw some lines onto a MKMapView like in this example. But somehow the lines are not being drawn in my iPad app though it's pretty much the same as in the example. Are there some kind of common pitfalls I should think about? It's been driving me nuts for the last two days. Thanks –f ...

In DetailViewController.h, it declares the interface as normal: @interface DetailViewController : UIViewController <UIPopoverControllerDelegate, UISplitViewControllerDelegate> { UIPopoverController *popoverController; UIT...

Can someone answer this definitively? It seems that sometimes changing the frame of a UIImageView resizes its image and sometimes it doesn't. I have loaded an image and created a UIImageView with it, sized about 100x100. Doing the following has absolutely no effect: myImageView.contentMode = UIViewContentModeScaleAspectFit; myImageView...
Hi, I have a window with a UIView and a transition to another UIView. But when I do the transition, the window to transition to is displayed in portrait, and after the transition is finished, it goes to landscape..

This is my first stab at creating two targets within one project for iPhone and iPad. My question is, if I save an array to NSUserDefaults, and the iPhone syncs with iTunes, and then I sync the iPad, will the iPad version have access to the array synced to it? ...
Is there some library that provides a UIView/UIViewController similar to the iPad popover on the iPhone? I'm just talking about a temporary view that appears on top of the current view, and does the nice transitions that a UIPopoverView does on an iPad. ...
I have been playing with the most excellent GrooveMaker - http://www.groovemaker.com/home - on iPad and marveling at how well the graphics sync to the audio. I will be building a imaging app where I need music to drive short animated loops. Can someone suggest what GrooveMaker might be doing and how that might be applied in a more genera...
For an iOS application I'm making I need to show groups of elements grouped together according to their type, and different groups of types separated from each other in a nicely done layout. I thought of using an undirected graph, with the grouped nodes all pointing to each other in a sort of circular reference, and then each group as ...
Are there any known pitfalls to avoid when storing user passwords in the Keychain? I am planning to give users the ability to require a password in order to access my iPad app. I have basic read and write of a string to the Keychain working. I just want to make sure that I don't allow them to get into a scenario that they lock themselves...
I hope this has a technical (rather than a religious) answer, but I wonder if I should use Objective-C or C++ to create an OpenGL ES Application on the iPad? As the ultimate goal would be to compile it on Windows and OS X as well, I'm inclined to use C++ (and only use ObjC for the stuff that I have to: App Delegate etc.), but I have zer...
I have been trying to solve this bug for 2 days straight and can't seem to find the problem.

So it can consider as a grid with UILabels(total no of labels = table rows * table columns). When the data gets refreshed I have added an animation for the UILabel to highlight the table ...
Hi, In a UIWebView (multi-touch enabled) I got a page with two divs (div1 and div2), each of them having registered for the touchstart and touchend events. Everytime they are receiving touch events, I am dumping the content of: event.touches: contains all current touches event.targetTouches: contains touches relevant to the given tar...
