CDAudioManager manages audio requirements for a game.
- Firmware: OS 2.2 or greater
- Files: CDAudioManager., CocosDenshion.
- Frameworks: OpenAL, AudioToolbox, AVFoundation
- 自从
- v0.8 It provides access to a CDSoundEngine object for playing sound effects. It provides access to two CDLongAudioSource object (left and right channel) for playing long duration audio such as background music and narration tracks. Additionally it manages the audio session to take care of things like audio session interruption and interacting with the audio of other apps that are running on the device.
Requirements:
- Firmware: OS 2.2 or greater
- Files: CDAudioManager., CocosDenshion.
- Frameworks: OpenAL, AudioToolbox, AVFoundation
- 自从
