Hi all.
I'm writing an iPhone app that interacts with a database over the Web
using XML, and PHP on the server side.
Obviously, delays in downloading data are frequent, so I'm using Grand
Central Dispatch to do a bunch of it asynchronously. This brings up a
basic question: How do I notify all

Hi all,
In a document-based app, I have the main Document xib a Loading xib. The
latter is shown while the program reads a file closes after.
When reading a file, my Document object tells LoadingWindowController to show
its window [loadingWindowController setDocument:self];
This is to

I had been using Graham's GCMathParser but we needed something more powerful,

excellent, albeit much more complex en Dave's or Graham's solution (I had to

Basically, if I add an observer using the path document.someProperty, KVO
attaches the observer to the the someProperty object, not document. So if I

Under 4.1 the reading is updated only when the heading changes. Under 4.2 it is

now it acts (more or less) the way I expect.
What I find strange is that when I bring a magnet near the

Rua,
This won't work with an instance of the custom view in the toolbar.
A workaround would be to use a borderless (Custom / No Border) NSBox instead of
a custom view. This is probably the most straightforward fix.

This most certainly works a treat.

I am thinking about doing something like this:
- to init a custom object, call a convenience initializer that in turn calls
the designated initializer
- in the convenience initializer, before the designated initializer is called,
check some conditions. If that test fails return nil.
Use the Keychain.
