ios - CLLocationManager 的多种实现

Question

我想知道在一个应用中实现两个使用 CLLocationManager 功能的不同 SDK 是否有问题。

两个 SDK 都在监控 CLBeaconRegions，并且都使用 CLLocationManager 实例和委托(delegate)实现实现了不同的类。

可能出现的问题:

如果其中一个 SDK 从它的 CLLocationManager 中删除所有受监控的 CLBeaconRegions 会怎样。这是否也会影响其他 SDK 的 CLLocationManager？

如果两个 SDK 开始寻找相同的 UUID(但具有不同的 CLBeaconRegion 标识符)怎么办...是否都收到委托(delegate)调用？

我想不出这不起作用的任何其他原因，但也许我遗漏了什么？

您尝试过共享实例吗？您可以做的是尝试使用相同的位置管理器实例来管理您的代码。因此，委托(delegate)中的任何更改都可能反射(reflect)在单个类中，您可以从那里管理您的代码。

例子:-.h

#import <Foundation/Foundation.h>
#import <CoreLocation/CoreLocation.h>
@interface LocationManager : NSObject <CLLocationManagerDelegate>
@property (nonatomic,strong) CLLocationManager         *objLocationManager;
@property (nonatomic,assign) CLLocationCoordinate2D    currentcoordinate;
+ (LocationManager *) SharedInstance;
+ (CLLocation *)      currentLocation;
@end

.m

#define currentCordinates [LocationManager SharedInstance].currentcoordinate
#define currentLocationmanger   [LocationManager SharedInstance].objLocationManager
// Shared Manager
static LocationManager *SharedInstance = nil;

+ (LocationManager *) SharedInstance
{
    @synchronized(self)
    {
        if (SharedInstance == nil)
        {
            SharedInstance = [[super allocWithZone:NULL] init];
            currentLocationmanger = [[CLLocationManager alloc]init];
            currentLocationmanger.delegate = [LocationManager SharedInstance];


            /* Pinpoint our location with the following accuracy:
             *
             *     kCLLocationAccuracyBestForNavigation  highest + sensor data
             *     kCLLocationAccuracyBest               highest
             *     kCLLocationAccuracyNearestTenMeters   10 meters
             *     kCLLocationAccuracyHundredMeters      100 meters
             *     kCLLocationAccuracyKilometer          1000 meters
             *     kCLLocationAccuracyThreeKilometers    3000 meters
             */
            currentLocationmanger.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;

            /* Notify changes when device has moved x meters.
             * Default value is kCLDistanceFilterNone: all movements are reported.
             */
            currentLocationmanger.distanceFilter = 2.0f;

            /* Notify heading changes when heading is > 5.
             * Default value is kCLHeadingFilterNone: all movements are reported.
             */
            currentLocationmanger.headingFilter = 5;

            [LocationManager SharedInstance].geocoder = [[CLGeocoder alloc] init];

            [[LocationManager SharedInstance].objLocationManager startUpdatingLocation];

            // update location
            if ([CLLocationManager locationServicesEnabled]){
                [currentLocationmanger startMonitoringSignificantLocationChanges];
            }
        }
    }
    return SharedInstance;
}

//.m 中要管理的其他委托(delegate)和内容

有些地方在你使用的时候是与共享实例一起使用

//region.span = span;
    region.center = [LocationManager SharedInstance].currentcoordinate;
