I'm building an app that has several different sections to it, all of which are pretty image-heavy. It ties in with my client's website and they're a "high-design" type outfit. One piece of the app is images uploaded from the camera or the library, and a tableview that shows a grid of thumbnails. Pretty reliably, when I'm dealing with t...

I'm wondering what's the easiest/best way to determine the magnitude of a given frequency in a sound. It's my understanding that a FFT function will return the magnitudes of all frequencies in a signal. I'm wondering if there is any shortcut I could use if I'm only concerned about a specific frequency. I'll be using the iPhone mic to r...
I've got quite a weird problem. To make it short, i'll write some pseudo-code: init: create a dictionary and insert n elements. create a "repeat timer" and add it to the currentRunLoop using the timerRefresh selector. timerRefresh: using a list of keys, find the items in the dictionary if the item exists -> call a f...

At the end of each record I need to clear my string variables but I read that someString = @"" actually just points to a new string & causes a memory leak. What is the best way to handle this? Should I rather use mutable string vars and use setString:@"" between iterations? ...

I have a subclass of UIView which draws itself based on data held in a corresponding model class, which is a subclass of NSManagedObject. The problem is, some fields in the data model (e.g. the position of the view) are already held in the view (i.e. the frame property in this case). I then have a data duplication/synchronization probl...

I'm still a bit unsure about exactly how the hierarchy should loo...
