线程1：我的CLLocationManager的EXC_BAD_ACCESS代码= 2，地址= 0x7ffee84eaf60

如何解决线程1：我的CLLocationManager的EXC_BAD_ACCESS代码= 2，地址= 0x7ffee84eaf60

我不知道为什么会这样或如何解决。错误：线程1：EXC_BAD_ACCESS（代码= 2，地址= 0x7ffee84eaf60）出现在我的行​​上：

let locationManager = CLLocationManager()

我在viewDidLoad（）以上的类中声明了它。我已经无数次运行此模拟器了很多次，现在它随机弹出了。我检查了一下是否是我添加的最新代码，方法是在没有上述代码的情况下再次运行它，并且错误仍然存​​在。以防万一，您并不是将我的默认位置设置为none，而是在之前遇到了该错误并进行了修复。这是使用locationManager的代码的所有部分：

let locationManager = CLLocationManager()

然后：

override func viewDidLoad() {
    super.viewDidLoad()
    
    locationManager.delegate = self
    locationManager.requestWhenInUseAuthorization()
    locationManager.startUpdatingLocation()
    
    mapView.delegate = self
    mapView.showsUserLocation = true
    
    tapToAddJumpSpotLabel.isHidden = true
}

然后：

@IBAction func allowLocationButtonpressed(_ sender: UIBarButtonItem) {

    switch CLLocationManager.authorizationStatus() {

    // Case when authorization not determined.
    case .notDetermined:
        locationManager.requestWhenInUseAuthorization()

    // Case when authorization granted.
    case .authorizedAlways,.authorizedWhenInUse:
        let alertController = UIAlertController(title: "Location Access Granted",message: "We already have access to your location.  If you want to change this,go to your settings app,and change our location access.",preferredStyle: .alert)

        let okayAction = UIAlertAction(title: "Okay",style: .cancel,handler: nil)

        alertController.addAction(okayAction)

        self.present(alertController,animated: true,completion: nil)

    // Case when authorization denied or restricted.
    case .restricted,.denied:
        let alertController = UIAlertController(title: "Location Access disabled",message: "We need access to your location in order to provide you with cliff jumping spots.",preferredStyle: .alert)

        let cancelAction = UIAlertAction(title: "Cancel",handler: nil)

        let openAction = UIAlertAction(title: "Open Settings",style: .default) { (action) in
            if let url = URL(string: UIApplication.openSettingsURLString) {
                UIApplication.shared.open(url,options: [:],completionHandler: nil)
            }
        }
        alertController.addAction(cancelAction)
        alertController.addAction(openAction)

        self.present(alertController,completion: nil)

    // Default (Apple has possible future cases to be added to CLAuthorizationStatus).
    @unkNown default:
        return
    }
}

最后：

//MARK: - CLLocationManagerDelegate Methods

extension ViewController: CLLocationManagerDelegate {

func locationManager(_ manager: CLLocationManager,didFailWithError error: Error) {
    if let error = error as? CLError,error.code == .denied {
        locationManager.stopUpdatingLocation()
        print(error)
        return
    }
    
}

func locationManager(_ manager: CLLocationManager,didUpdateLocations locations: [CLLocation]) {
    let lastLocation = locations.last!
    mapView.centerCoordinate.latitude = lastLocation.coordinate.latitude
    mapView.centerCoordinate.longitude = lastLocation.coordinate.longitude
}

}

我不知道是什么原因造成的，因此不胜感激：）

解决方法

嗯，经过进一步的挖掘，我感到很愚蠢。只是一个旧对象在另一个类中进行初始化，反之亦然，导致无限循环。好东西是其中之一很旧，我只是忘了删除它，所以去吧！
