Decided on a long name for your application when you created it, but are now fed up of seeing it display like this on the home screen?
You can quickly and easily change the display name of your application but amending InfoPlist.strings to the following
/* Localized versions of Info.plist keys */ CFBundleDisplayName = "My App";
Easy as that, since the plist file is localised, we can use this for multiplate languages/locales.
Sending Tweets from your iOS5 app, easy!

Sending a tweet from your iOS application could not be any easier, Apple and Twitter really were looking out for their developers.
With iOS 5, the twitter account is authenticated under the settings menu of the device, which means that any application can request this account to use for tweet, and that is all you need to do; sign in, then request these details in your application.
Follow these easy steps
Sign into twitter on your phone
Go to Settings > Twitter > Sign in, as displayed below
Improving Tesseract OCR results on the iOS platform

If you’ve found yourself using Tesseract on the iOS platform, and you’re scratching your head as to why the OCR results are so terribly incorrect, you might be interested in the following. Most of the tesseract iOS tutorials talk about compiling the libraries, but don’t really cover how to use it.
Theres always an app for that, but how do you understand how it works?
Are you using something like this to interface with the tesseract API?
char* text = tess->TesseractRect(imageData,(int)bytes_per_pixel,(int)bytes_per_line, 0, 0,(int) imageSize.height,(int) imageSize.width); NSLog(@"Converted text: %@",[NSStringstringWithCString:text encoding:NSUTF8StringEncoding]);
I was using this to start with, and the results were terrible, if it was able to read anything it was mostly returning special characters or just utter nonsense.
