ios定期获取我的位置，并设置button来获取我的位置 – 谷歌地图不工作
我正在使用Google Map Module，使用1.9.0 Bundle来定期查找我的位置，比如说10秒钟，并创build一个button来获取我的位置button作为一个地图视图设置
当执行和位置服务打开时，单击右下angularbutton后没有响应，位置pipe理器不工作。 我可以显示使用位置服务的任何迹象。
我不知道我在设置这个地图上缺less什么，因为我严格遵循SDKDemos – iOS的谷歌演示项目来设置我的模块。 你能告诉我确切的方法来设置它吗？
以下是我的代码：
@implementation MapViewController -(bool)isNetworkAvailable { SCNetworkReachabilityFlags flags; SCNetworkReachabilityRef address; address = SCNetworkReachabilityCreateWithName(NULL, "www.apple.com" ); Boolean success = SCNetworkReachabilityGetFlags(address, &flags); CFRelease(address); bool canReach = success && !(flags & kSCNetworkReachabilityFlagsConnectionRequired) && (flags & kSCNetworkReachabilityFlagsReachable); return canReach; } - (void)requestAlwaysAuthorization { CLAuthorizationStatus status = [CLLocationManager authorizationStatus]; // If the status is denied or only granted for when in use, display an alert if (status == kCLAuthorizationStatusAuthorizedWhenInUse || status == kCLAuthorizationStatusDenied) { NSString *title; title = (status == kCLAuthorizationStatusDenied) ? @"Location services are off" : @"Background location is not enabled"; NSString *message = @"To use background location you must turn on 'Always' in the Location Services Settings"; UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:title message:message delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Settings", nil]; [alertView show]; } // The user has not enabled any location services.

NSLocationAlwaysUsageDescription – >位置是需要找出你在哪里NSLocationWhenInUseUsageDescription – >位置是需要找出你在哪里
我的testing设备是8.3，iphone 6
你的- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{ get called？
如果没有，你需要确保你的MapViewController实现了CLLocationDelegate 。 （例如： MapViewController.h文件中的@interface ViewController : UIViewController<CLLocationManagerDelegate> ）
你可以试试GitHub的这个工作例子 ，或者从这个Gist 的代码片断 。
另外，你应该在你真实的设备上testing它，否则你必须在你的XCode模拟器中模拟一个位置（见下图，但它可能不总是工作）。
您必须将NSLocationWhenInUseUsageDescription或NSLocationAlwaysUsageDescription添加到您的info.plist文件（注意：不要重命名或更改info.plist文件的扩展名，扩展名必须为.plist ）：
