I was also facing same crash while using Folioreader in my app. I have fixed it by doing below changes in my code.
In FolioReaderAudioPlayer.swift file. Update these 5 methods.
#objc func pause() -> MPRemoteCommandHandlerStatus {
playing = false
if !isTextToSpeech {
if let player = player , player.isPlaying {
player.pause()
}
} else {
if synthesizer.isSpeaking {
synthesizer.pauseSpeaking(at: .word)
}
}
return .success
}
#objc func togglePlay() -> MPRemoteCommandHandlerStatus {
isPlaying() ? pause() : play()
return .success
}
#objc func play() -> MPRemoteCommandHandlerStatus {
if book.hasAudio {
guard let currentPage = self.folioReader.readerCenter?.currentPage else { return .commandFailed }
currentPage.webView?.js("playAudio()")
} else {
self.readCurrentSentence()
}
return .success
}
#objc func playPrevChapter() -> MPRemoteCommandHandlerStatus {
stopPlayerTimer()
// Wait for "currentPage" to update, then request to play audio
self.folioReader.readerCenter?.changePageToPrevious {
if self.isPlaying() {
self.play()
} else {
self.pause()
}
}
return .success
}
#objc func playNextChapter() -> MPRemoteCommandHandlerStatus {
stopPlayerTimer()
// Wait for "currentPage" to update, then request to play audio
self.folioReader.readerCenter?.changePageToNext {
if self.isPlaying() {
self.play()
}
}
return .success
}
