AVAudioSession Interruptions

阅读更多关于 AVAudioSession Interruptions

So in my app, running on iOS 6, everything seems to work fine with audio. I use the old C API format to catch interruptions using a callback; setting up via: AudioSessionInitialize(NULL, NULL, interruptionListenerCallback, (__bridge void *)self) and it was great. Using iOS 7 SDK though, it seems that my interruption callback is never called when the device receives calls or an alarm goes off. After some looking around, I heard that the old C api were deprecated and that you should move to the newer AVAudioSession functions. More reading revealed that the AVAudioSession delegate is deprecated

If I have a function with a try/finally section, and the thread running it is interrupted while in the try block, will the finally block execute before the interruption actually occurs?

Here's the full passage: The finally block always executes when the try block exits. This ensures that the finally block is executed even if an unexpected exception occurs. But finally is useful for more than just

When does Java's Thread.sleep throw InterruptedException? Is it safe to ignore it? I am not doing any multithreading. I just want to wait for a few seconds before retrying some operation. Benny Bottema You should generally NOT ignore the exception. Take a look at the following paper: Don't swallow interrupts Sometimes throwing InterruptedException is not an option, such as when a task defined by Runnable calls an interruptible method. In this case, you can't rethrow InterruptedException, but you also do not want to do nothing. When a blocking method detects interruption and throws
