ios - Google Maps SDK for iOS 在发布到 App Store 后崩溃

Question

我在我的 iOS 应用程序中集成了 Goole Map (v1.5)，当我在真实设备 (iPad 4 iOS 6.1) 上以 Debug模式对其进行测试时，它工作正常。

我发布了我的应用程序，但当用户打开 map 时应用程序崩溃了。

我不知道问题出在哪里，为什么会崩溃。

ELocation.m 加载 View :

    _locationManager = [[CLLocationManager alloc] init];

    _locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    _locationManager.delegate = self;

    [_locationManager startUpdatingLocation];

    _destLocation = nil;

    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:_locationManager.location.coordinate.latitude longitude:_locationManager.location.coordinate.longitude zoom:12]; //**line 45**

    mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];

    mapView.settings.zoomGestures = YES;

    mapView.settings.myLocationButton = YES;

    mapView.myLocationEnabled = YES;

    mapView.delegate = self;

    self.view = mapView;

}

Answer 1

当您调用 [_locationManager startUpdatingLocation] 时，您将在位置可用时通过 locationManager:didUpdateLocations: 收到回调，稍后会异步接收。在那之前，_locationManager.location 可能为 nil - 尽管如果您的应用之前已经缓存了位置，则可能不是。

这可能对于之前没有运行过应用程序的用户来说是导致崩溃的原因，因为在第 45 行，您假设您有一个有效的位置来创建相机位置。虽然我不确定，因为在 nil 上调用 .coordinate.latitude 应该只返回 0 而不是崩溃。

可能是系统提示您的用户访问其位置，而在他们回答"is"之前尝试访问该位置是导致崩溃的原因。要在您自己的设备上重现该内容，您需要重置您的位置和隐私设置。通过设置 -> 通用 -> 重置 -> 重置位置和隐私来执行此操作。不幸的是，这会为您的所有应用程序和所有隐私选项(即位置、照片、联系人等)重置它。即使您删除并重新安装您的应用程序，iOS 也会记住您之前的回答是"is"。一种更简单的方法可能是尝试临时更改您的包 ID，但您还需要获取新的 Google map key 。
