What is the right way to play next file using Audio Queue Services? When "play next" button is pressed should I first call AudioQueueStop and then AudioQueuePrime/AudioQueueStart or it is enough to just fill buffers with next file data? The problem is that the latter gives me sound glitches on iPhone. ...

I am currently doing a lot of data wrangling. I ingest a lloonngg NSData byte streams and then parse that data. The parsing is trivial. However, I have to simulate consumption of the data as I parse via not particularly elegant bookkeeping. Here is what a typical method looks like in the category of NData I have implemented: // Grab a l...
I've got a custom ModalDialog class, which I've got working well in most situations. It returns its results via a delegate method, which then continues the app appropriately based on the user's button selection. However, there are some places in my app where the dialog really needs to pop up in the middle of a method (for example, my ga...

I'm writing an iPhone app that requests data from a web service, and in order to get that data, I'm using NSMutableURLRequest. The problem that I am having is that the amount of data being requested is quite large (~11Mb), and this is causing my app to be killed by the OS. Is there any way of streaming the data in a way that will allow...
What's the best way to get a reference to other views using default controllers? My MainView.xib is a TabBarController, and I want to know the best way to call methods from one view on another, or change data properties. Any transfer of data will also necessitate that the tabs switch, but I haven't figured out how to programatically cont...

However, I'm still getting "framework not found" ...
