I have managed to get to the point where I can record and play the recordings with AVAudioRecorder and AVAudioPlayer. But whenever I try to record, pause recording and then play, the playing part fails with no error. I can guess that the reason it's not playing is because the audio file hasn't been saved yet and is still in memory or something. Is

问题 I'm stuck on some weird memory leak problem related to the AVAudioPlayer and I need help after trying everything that came to mind. Here is the short description of the problem - code appears right after.
