The system seems to change this ba...

As you may all know (if not, click here), Apple has finally decided to allow apps created using Adobe Flash CS5's iPod Packager on the store. Owning a PC and not a Mac, this is great news for me as I longed to give a crack to iPod development. I did try to use a fake certificate (yes I admit it) to publish an app and test it on my brot...
Hi guys, I know that it's trivial to add a red number badge to an app's icon on the home screen. What's the best way to get a badge that looks like this within my app?

I have created a new application using the View Based Application Template in xCode. My first view, which displays on loading the app, is a button based menu. One of the buttons (Make) should load a new navigation stack using a NavigationViewController. There are other buttons that when implemented will do other things outside of Navig...
I am currently trying to setup a NSFetchedResultsController that will order my table view based on the number of entities in a to-many relationship. I am not sure if this makes a difference when counting, but this is also an inverse relationship. I thought something like this would work just fine: NSEntityDescription *entity = [NSEntit...

When I test iAd on the simulator, I get the test advertisement with no problem. When I try to test it on the device, all I get are calls to ...
I'm attempting to ad AdMob to an iPhone app as a backup for iAd, unfortunately, I can't follow the documentation. It's telling me to add the 'MediaPlayer' and 'MessageUI' frameworks, but they don't appear to be present -- I can add a number of other frameworks, but those two are AWOL. Please note that I can add any number of other fram...

My app's icon is named: appicon57x57.png This works great on simulator and device. I don't have a retina device to test on. But if I make a 114x114 version of my app icon and call it: [email protected] and put in in the same place as the other icon, will it show on the retina devices? ...
Hi there, Sorry for the long title. In essence, I want to accomplish the same thing that the Calendar app does for Event details. The first cell shows the title and date of the event. The second shows an alert, if there is one, otherwise Notes, if there are any, or nothing else if none of these fields is present. The way I am doing it ...
Aside from the WYSIWYG editor, what are the advantages of using XIB/NIB files over defining the layout in code in iPhone/iPad/iOS? While I don't find XIB files much useful, many iOS developers do, which makes me suspect I might not know their benefits or how to use them properly. ...
