I have an array of dictionaries. I would like to filter that array by seeing if the @"name" field of each dictionary contains a given string. The catch is that I would like to make my filtering insensitive to case and diacritics. If the array contained only strings I could easily use an NSPredicate. However, it doesn't, and I don't s...

Situation I'm using NSURLConnection to download an mp3 file to the documents directory on my app. On the simulator I get the full mp3 file downloaded with no probs.

Sort of an hollisti...

I'm really new at this. I've been working my way through a couple of "HelloWorld" type tutorials that basically have a text field, a button, and when you click the button it alerts whatever's in the text field. I've gotten as far as getting an alert to show and being able to set the title, message, and button text directly. However my at...
