I wonder if it would be more secure to rely on a NSNumberFormatterBehavior10_4 instead of default, because default may change arbitrary some day in future, and suddenly the app looks ugly. Or am I wrong with that? ...
The documentation is hard to interpret on this topic. Does this value return me how many characters the calculated format string will contain? Or does it tell me how big actually that string is? Or can I tell it how big (in unit squares or "pixels") the output should be? Maybe someone can point out what this methods do... ...

Background: I have created an application that allows users to submit an entry to an online database, and view other entries from that database. These entries contain geocodes for latitude and longitude which are used for positioning the annotations on the MapKit. Users can submit the location using either their current location or an ad...
That looks like a bug in the API: When my input CGFloat is 0.0, I get this: Input = 0.000000, Output = +0 When my input CGFloat is 1.0, I get this: Input = 1.000000, Output = +2 Obviously that's not what I want ;-) Now here is how I create that NSNumberFormatter object: NSNumberFormatter *formatter = [[NSNumberFormatter allo...
Hello I found out how to send some text on the user's wall, with the FBConnect API, on iphone.
