ios定期获取我的位置并设置按钮获取我的位置-谷歌地图不起作用

我正在使用Google地图模块，使用1.9.0捆绑包，定期查找我的位置，比如说10秒，并创建一个按钮以获取我的位置按钮作为mapview设置之一

当执行和位置服务打开时，无论是否单击右下角按钮，都没有响应，位置管理器不工作。我可以显示任何使用定位服务的迹象

我不确定我在设置这个地图时遗漏了什么，因为我严格按照SDKDemos-ios谷歌演示项目来设置我的模块。请告诉我确切的设置方法好吗

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;
}

    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

        [alertView show];
    }

我已经在我的项目中设置了pinfo.list的以下参数

NSLocationAlwaysUsageDescription->Location是查找您所在位置所必需的 NSLOCATIONWhenUsageDescription->Location是查找您所在位置所必需的

我的测试设备是8.3，iphone6

你的

-（void）locationManager:（CLLocationManager*）管理器没有更新位置：（NSArray*）位置{

被呼叫了吗

如果没有，则需要确保

MapViewController

实现

CLLocationDelegate

（例如：

@interface ViewController:UIViewController

在

MapViewController.h

文件中）

您可以从GitHub或本指南中进行尝试

此外，您应该在真实设备中测试它，否则您必须在XCode模拟器中模拟一个位置（参见下图，但它可能并不总是有效）

您必须将

nslocation当不使用usagedescription

或

NSLocationAlwaysUsageDescription

添加到

info.plist

文件时（注意：不要重命名或更改

info.plist

文件的扩展名，扩展名必须是

.plist

）：
