在 Swift 中,如何让音乐在用户使用我的应用程序时继续播放? (快速用户界面)
In Swift, How can I make music keep playing while user is using my app? (swiftUI)
当用户点击按钮时,它会播放音乐,然后停止播放背景音乐。但我想要的是背景音乐即使在用户点击按钮后也能继续播放
这是播放音乐的代码
@State var bombSoundEffect: AVAudioPlayer?
Button("Button") {
let path = Bundle.main.path(forResource: "example.mp3", ofType:nil)!
let url = URL(fileURLWithPath: path)
do {
self.bombSoundEffect = try AVAudioPlayer(contentsOf: url)
self.bombSoundEffect?.play()
} catch {
// couldn't load file :(
}
}
如何让背景音乐在用户点击此按钮后继续播放?
将下面的代码放在self.bombSoundEffect = try AVAudioPlayer(contentsOf: url)
之前
_ = try? AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, mode: .default, options: .mixWithOthers)
为了可重用性,我发现创建一个 class 非常有用,可以避免在其他视图中重复代码。
class Sounds {
static var audioPlayer: AVAudioPlayer!
static func play(sound: String, type: String) {
if let path = Bundle.main.path(forResource: sound, ofType: type) {
do {
//Doesn't stop background music
_ = try? AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, mode: .default, options: .mixWithOthers)
//Load & play sound
audioPlayer = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: path))
audioPlayer?.play()
} catch {
print("Error playing sound")
}
}
}
}
然后像这样
通过Button
在你的视图中使用它
Button("Play Sound") {
Sounds.play(sound: "bombSoundEffect", type: "mp3") //Local file example
}
