ios - 尝试获取用户位置时出错(快速)

Question

我正在尝试获取用户在 iOS 上的位置。我使用 CLLocationManagerDelegate 来实现它。

if CLLocationManager.locationServicesEnabled() {
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
    locationManager.requestLocation()
}

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let location = locations.first
    print("locations = \(location?.coordinate.latitude) \(location?.coordinate.longitude)")
}

但我收到此错误

2017-03-24 18:03:57.183 *** Assertion failure in -[CLLocationManager requestLocation], /BuildRoot/Library/Caches/com.apple.xbs/Sources/CoreLocationFramework_Sim/CoreLocation-2100.0.34/Framework/CoreLocation/CLLocationManager.m:867
2017-03-24 18:03:57.194 *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Delegate must respond to locationManager:didFailWithError:'

实现locationManager:didFailWithError:后

func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
    print(error.description)
}

我有这个警告

Instance method 'locationManager(:didFailWithError:)' nearly matches optional requirement 'locationManager(:didFailWithError:)' of protocol 'CLLocationManagerDelegate'

又出现这个错误

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Delegate must respond to locationManager:didFailWithError:'

不知道哪里错了。 locationManager:didFailWithError: 已实现，但我有同样的错误。

Answer 1

更改为

@objc(locationManager:didFailWithError:)
func locationManager(_ manager: CLLocationManager, didFailWithError error: NSError) {
    print(error.localizedDescription)
}

对我的情况有帮助
