Ok, so I've been using NSLog in objective-C for awhile now to debug and I know it's supposed to print to the terminal whatever I put in the parentheses. For some reason, it just stopped printing to the terminal and I'm not sure how to fix this error. I was wondering what other people would suggest doing to fix this problem. I've only inc...
I'm learning ObjectiveC and ran into a problem relating to introspection. Basically, I'm looping through an array of objects and determining if they accept the lowercaseString selector.

Hello, I am using an NSDocumentController subclass to do some custom stuff when I create my NSDocuments. The strange thing is that when the document is created, the Save option in the menu is disabled.

From the isKindOfClass: method documentation in NSObject: Be careful when using this method on objects represented by a class cluster. Because of the nature of class clusters, the object you get back may not always be the type you expected. The documentation then proceeds to give an example of why you should never ask something like th...

I can get the tests working for the public interface to my classes (although I'm still on the fence because I'm writing more testing code than there is in the methods being tested).
