We all love Siri’s little witty quips, but I recently read a heartwarming article over on Mashable that reflects the power of technology to change lives in ways that most of us would never appreciate. I won’t spoil
Now more than ever, we have the power to change humanity with technology, and today we are helping cure cancer. Over the last 5 years cancer has taken away many people close to me, and
So today I realised it was Earth Hour. The event didn’t have much hype this year so I suppose you can forgive me for forgetting about it. The only reason I remembered it was because
When developing on the Mac and using custom frameworks in your application, when you compile the frameworks are copied into your applications bundle then linked at runtime. These frameworks will most likely be bundled up with their headers. Some of the frameworks you include may not be things you want to make public to the world, which you are essentially doing by including the headers with the framework.
Since Xcode 4.1 when your application throws an exception your console just prints a list of function pointers and you don’t get a proper stack trace. This isn’t helpful if you’re trying to find the exact line the error occurred on.
In Xcode the build settings screen can be pretty daunting for some people, especially when you start iOS/Mac development. Knowing which settings to pick can be tricky, but I still see a lot of people that do this individually for each of their projects, which makes it easy to miss crucial build parameters you don’t want to distribute your app without. Using a .xcconfig file is extremely useful for solving this problem, it is a type of file for determining build parameters, meaning you can have this file sitting in one spot and have each of your projects referencing it. If you need to make a build setting change to all your projects, you can just add it to this one file and the next time you compile each of the projects the change will be taken into account.

In Objective-C most things that get passed around inherit from NSObject. Because of this when you want to add a primative type to an array or dictionary you need to wrap it in an NSObject, usually an NSNumber.
