(Objective C) Quickest Way to Shell - Use system() instead of NSTask - zingo

Sat, 09 Jul 2011 04:53:37 GMT

Cocoa provides NSTask to run subprocesses. It can be used to run shell scripts, but all this manual pipe and file handling is a bit cumbersome. Fortunately, for a simple script, we can use the trusty old system and redirect its result to a file.

(Objective C) Checking If You App Has Been Run Before - zingo

Thu, 26 May 2011 14:19:04 GMT

Do you need you app to do something when it is first run on a certain computer? Do you need to know if it has been run before? Enter the following code into your Application Delegate. This code creates a BOOL that is created when the app is run. The if-else statement reads the value of the BOOL -- Yes or No. NOTE: You'll notice that if you run the app from xcode with the run button it says "Not run before". When you run it again it still says that. In order to truly test locate you apps Debug .app application then run that. Xcode clears out the data when you run it again. IT DOES WORK though, so don't worry if running you app in Xcode still gives you the Not Run Before result.

(Objective C) Sending emails from Cocoa - zingo

Sat, 23 Jan 2010 22:02:38 GMT

With 10.5 Apple deprecated the use of NSMailDelivery – without a replacement. So the questions comes up regulary – how does one send emails from Cocoa? Turns out there are couple of frameworks available that can also be used to do the job. * Pantomime (LGPL license) - http://www.collaboration-world.com/pantomime/ * MailCore (New BSD license) - http://www.mronge.com/m/MailCore/ * EDMessage (BSD syle license) - http://www.mulle-kybernetik.com/software/EDFrameworks/download.html#EDMessage EDMessage has been around for ages. Checkout the example on how to use the API. MailCore is also really easy to use. But both lack support for asynchronous mail delivery. With MailCore I couldn’t even work out how to send attachments. Also no idea if it’s getting developed anymore. So if you are OK to use a LGPL library Pantomime seemed like a good choice. Sending simple emails is quite straight forward.

(Objective C) UIView and Subviews Exploded - phifty

Tue, 11 Aug 2009 22:04:04 GMT

This is adapted from Erica Sadun's explode code in her book "iPhone Developer's Cookbook". It takes any UIView-based element and exposes all of the subviews and their subviews, etc. Its a good way to dig into UIKit elements as well as debug your own UIView-based code. In code, always set level to zero.

(Objective C) Kill App after Expire Date (Suicidal Code Redux) - zingo

Wed, 09 Jul 2008 22:39:05 GMT

Using a gcc predefined macro, __DATE__, the code can know for itself when it was compiled, and build in an expiration date based on that value. The former code (http://snipplr.com/view/3448/kill-app-after-expire-date/) was not internationalised and might cause an issue when run outside of English speaking countries. This code resolves the locale issue.
