(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) 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.

(Objective C) Importing data with coredata - zingo

Thu, 11 Oct 2007 21:57:17 GMT

A database table is basically an array of dictionary objects. As long as all the fields are valid property list types, you can loop through the array creating a managed object for each dictionary and setting the values. If you have an array controller in your nib and it's configured for your managed object, you can use this (where plist is expected to be an NSArray* - not sure why I made it an id).
