The iPhone's accelerometer is very sensitive. If I log acceleration values with a frequency of 100Hz, there are so many values related to noise, car vib...

There are hundreds of videos, each with about ten attributes. (The videos are never downloaded, only streamed, using MPMoviePlayerC...

I have a UITableView that is loaded from an NSMutableArray. The array is populated by data that I get from a RESTful web service request. In order to speed up the delivery of data to the user, I'm using a couple other NSArrays to hold a cache of the next sets of data. What I've done is when i'm nearing the end of my current set, in ...
Our application is using a few ports out of the standard ones (80 etc) and users are complaining that our app doesn't work but in fact it is their network that is restricting their access to those ports. Is there a way to detect this in the code so that we can warn them with some sort of error? ...

It seems that if I store NSNumber in two dictionaries with the value from one serving as the key to the other, sometimes, the key isn't found in the 2nd dictionary even though I'm certain it's in there. What I'...
Is there a way to get any kind of thread identifier of the currently running thread without resorting to Objective-C's NSThread. I'm improving our custom debug tracing system to handle multiple threads properly. For each line of trace output, I'd like to print a thread id or a thread name. Threads are instantiated in various ways, e.g....
