I'm trying to use a method from a class I downloaded somewhere. The method executes in the background while program execution continues. I do not want to allow program execution to continue until this method finishes. How do I do that?

 if(self=[super initWithCoder:aDecoder])

This is the code that makes the progress meter pop up.

This will show a progress meter while the method myTask is running.

            Is it possible to use the iPhone's hardware accelerated decoding of mp3s and AAC when using the OpenAL library?
I suppose there are two possible approaches if this is possible.
iPhone specific OpenAL extensions.
iPhone APIs to decode audio into raw bytes.
I have two specific use cases.

In my table view, if the user taps one particular cell, I slide up a UIView that contains a toolbar with bar items and a picker view (it very much behaves like an action sheet).

            In my project, the iPhone 4 does not show italics for command       
textLabel.font=[UIFont italicSystemFontOfSize:16];
but the iPhone 3 shows italics properly. 
Is it true that iPhone 4 does not support italics? If not using systemFont, can you get italics?
thanks,

I'm having a problem figuring out how to represent a many-to-many relationship model in a NSTokenField. I have two (relevant) models:
Item
Tag
An item can have many tags and a tag can have many items. So it's an inverse to-many relationship.
What I would like to do is represent these tags in a NSTokenField. I would like to end up...
