Not sure how to properly subclass UIApplication while using storyboards
I want to return to my storyboard’s initial viewcontroller after X time of user inactivity (no touch events fired). After some research I see that the most common way of detecting inactivity is to fire an NSTimer and reset the interval when an event is fired. To detect a fired event, we override [UIApplication sentEvent:] […]
Connect to MySQL directly from an iPad app (not via PHP, etc.)
Before anyone has a chance: Yes, i know it’s a bad idea. Please, don’t give me a lecture on how i should use a web service instead. Thanks. So, how could this be done? I found this bit http://www.karlkraft.com/index.php/2010/09/17/mysql-for-iphone-and-osx/ and thought it might do the trick. I got a bunch of ARC error messages, cleaned […]

Remove ability for portrait orientation for app in iPhone SDK
Is there a way where I can only allow my app viewable in landscape mode? I’ve managed to default the application’s orientation to landscape, however in the iPad simulator, when I do Command->Arrow, the application rotates to portrait. I’ve removed the listings in the plist under “Supported interface orientations” for both of the Portrait entries, […]
Why is my object not being passed correctly via segue?
Say I have 2 controllers, BarViewController and FooViewController. FooViewController has an outlet to a UIImageView called imageView: @property (nonatomic, weak) UIImageView *imageView; BarViewController has an outlet to a UIButton button.

I am using the iOS 5.1 SDK with Xcode 4.2 on Snow Leopard, which I understand is not an “officially supported” configuration. However, I can’t imagine why that would affect what is happening purely on the […]
Trying to understand AVAudioPlayer and audio level metering
I’m trying to understand AVAudioPlayer and audio level metering. What I have below is an object “AudioPlayer” that is playing a short audio sound. Now I want to output the power of this sound (decibels). Somehow I don’t think I’m doing this right. audioPlayer.meteringEnabled = YES; [audioPlayer play]; int channels = audioPlayer.numberOfChannels; [audioPlayer updateMeters]; for […]
Localizable.strings (base) x English
When you localize a file on Xcode 5 now, you have this “base” file, that I understand will be used if the user is using another language that was not localized. On older versions of Xcode, you did not have that. I want english to be the base language, that will be used by default. […]
