当按下按钮时，我正在尝试播放和循环铃声，在播放铃声时我还有其他逻辑运行 .
在没有其他逻辑的情况下进行测试时，铃声不会中断，但在添加其他逻辑时会被中断 .
我怎样才能避免这种中断？注意：铃声播放一两秒然后停止 .
func makeVideoCall(callReceiverId : String) {
self.playSound(nameOfAudioFileInAssetCatalog: "outgoingRingtone2")
// Other logic/code executed here, like making calls to the backend and calling callKit functions
}
func playSound(nameOfAudioFileInAssetCatalog: String) {
//private
if let sound = NSDataAsset(name: nameOfAudioFileInAssetCatalog) {
do {
try! AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
try! AVAudioSession.sharedInstance().setActive(true)
try self.soundPlayer = AVAudioPlayer(data: sound.data, fileTypeHint: AVFileTypeWAVE)
self.soundPlayer!.numberOfLoops = -1 // By setting to -1 the sound will be played infinitely, and will be stopped when the participant adds videotrack or when there is an error connecting the call
self.soundPlayer!.play()
} catch {
print("error initializing AVAudioPlayer")
}
}
}
