我正在尝试制作一个应用程序，您可以在一定时间内按尽可能多的按钮以获得积分。在过去的一周左右的时间里，我每天都在我的 iPhone 上构建并运行它，但现在 Xcode 突然给我一个错误“segmentation failure 11”。我已经删除了添加的代码，从 Storyboard 中删除了一些内容，甚至重新安装了 Xcode，但没有任何方法可以解决问题。有关于如何修复它的文章和视频，但似乎都不适合我。
这是我的代码:
import UIKit
import Foundation
import AudioToolbox
// PlaySounds
class PlaySounds {
private var soundID: SystemSoundID = 0
public init(named name: String) {
if let soundURL = soundURL(forName: name) {
let status = AudioServicesCreateSystemSoundID(soundURL as CFURL, &soundID)
if status != noErr {
print("Unable to create sound at URL: '\(name)'")
soundID = 0
}
}
}
public func play() {
if soundID != 0 {
AudioServicesPlaySystemSound(soundID)
}
}
private func soundURL(forName name: String) -> URL? {
let fileExtensions = ["m4a", "wav", "mp3", "aac", "adts", "aif", "aiff", "aifc", "caf", "mp4"]
for fileExtention in fileExtensions {
if let soundURL = Bundle.main.url(forResource: name, withExtension: fileExtention) {
return soundURL
}
}
print("Unable to find sound file with name '\(name)'")
return nil
}
deinit {
if soundID != 0 {
AudioServicesDisposeSystemSoundID(soundID)
}
}
}
// ViewController
class ViewController: UIViewController {
let startTimer = Timer.scheduledTimer(timeInterval: 0.4, target: self, selector: #selector(UIMenuController.update), userInfo: nil, repeats: true)
let XDSound = PlaySounds(named: "XDDDDDDD")
@IBAction func playButtonPressed(_ sender: AnyObject) {
XDSound.play()
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

它在错误的底部显示“swift:56:40”，我认为这意味着第 56 行的第 40 个字符，但所有这些都是 ViewController 的左括号。帮忙？
最佳答案
初始化计时器的行导致错误。
您不能在类的顶层调用目标/操作方法。
将变量声明为隐式未包装可选
var startTimer : Timer!
并在viewDidLoad中初始化它
override func viewDidLoad() {
super.viewDidLoad()
startTimer = Timer.scheduledTimer(timeInterval: 0.4,
target: self,
selector: #selector(UIMenuController.update),
userInfo: nil,
repeats: true)
}
或者将变量声明为带有闭包的lazy
lazy var startTimer : Timer = {
return Timer.scheduledTimer(timeInterval: 4.0, target: self, selector: #selector(update), userInfo: nil, repeats: false)
}()
并调用它来启动计时器
let _ = startTimer
