关于配置官方文档写的很全，简单描述2点
1、建议pod
platform :ios, '7.0'
target 'myApp' do #工程名字
pod 'BMKLocationKit'
end
2、plist.info 配置
NSLocationWhenInUseUsageDescription：表示应用在前台的时候可以搜到更新的位置信息；
NSLocationAlwaysUsageDescription：表示应用在前台和后台（suspend 或 terminated）都可以获取到更新的位置数据；
NSLocationAlwaysAndWhenInUseUsageDescription：申请永久定位权限，以便应用在前台和后台都可以获取位置数据；
直接上代码
引头文件
#import <BMKLocationkit/BMKLocationComponent.h>
添加属性, 配置授权代理,持续定位代理
@interface AppDelegate ()<BMKLocationManagerDelegate,BMKLocationAuthDelegate>
@property (nonatomic, strong) BMKLocationManager *locationManager;
@property (nonatomic ,assign) BMKLocatingCompletionBlock completionBlock;
@end
配置百度地图key，并且初始信息，这里采取的是 百度推荐的 kCLLocationAccuracyHundredMeters ，偏差在百米左右，超时时间设置在2s-3s左右即可，allowsBackgroundLocationUpdates 此时设置NO（不允许后台定位）
// 地图配置
- (void)setLocationConfig
{
// 百度地图key
[[BMKLocationAuth sharedInstance] checkPermisionWithKey:@"百度开发者申请的地图key" authDelegate:self];
//初始化实例
_locationManager = [[BMKLocationManager alloc] init];
//设置delegate
_locationManager.delegate = YES;
//设置返回位置的坐标系类型
_locationManager.coordinateType = BMKLocationCoordinateTypeBMK09LL;
//设置距离过滤参数
_locationManager.distanceFilter = kCLDistanceFilterNone;
//设置预期精度参数
_locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters;
//设置应用位置类型
_locationManager.activityType = CLActivityTypeAutomotiveNavigation;
//设置是否自动停止位置更新
_locationManager.pausesLocationUpdatesAutomatically = NO;
//设置是否允许后台定位
_locationManager.allowsBackgroundLocationUpdates = NO;
//设置位置获取超时时间
_locationManager.locationTimeout = 2;
//设置获取地址信息超时时间
_locationManager.reGeocodeTimeout = 2;
}
单次定位block
// 单次定位block
- (void)singleLocationBlock
{
self.completionBlock = ^(BMKLocation *location, BMKLocationNetworkState state, NSError *error)
{
if (error)
{
NSLog(@"locError:{%ld - %@};", (long)error.code, error.localizedDescription);
}
if (location) {//得到定位信息，添加annotation
if (location.location) {
NSLog(@"LOC = %@",location.location);
}
if (location.rgcData) {
NSLog(@"rgc = %@",[location.rgcData description]);
}
if (location.rgcData.poiList) {
for (BMKLocationPoi * poi in location.rgcData.poiList) {
NSLog(@"poi = %@, %@, %f, %@, %@", poi.name, poi.addr, poi.relaiability, poi.tags, poi.uid);
}
}
if (location.rgcData.poiRegion) {
NSLog(@"poiregion = %@, %@, %@", location.rgcData.poiRegion.name, location.rgcData.poiRegion.tags, location.rgcData.poiRegion.directionDesc);
}
}
};
}
持续定位代理
- (void)BMKLocationManager:(BMKLocationManager * _Nonnull)manager didUpdateLocation:(BMKLocation * _Nullable)location orError:(NSError * _Nullable)error
{
if (error)
{
NSLog(@"locError:{%ld - %@};", (long)error.code, error.localizedDescription);
} if (location) {//得到定位信息，添加annotation
if (location.location) {
NSLog(@"LOC = %@",location.location);
}
if (location.rgcData) {
NSLog(@"rgc = %@",[location.rgcData description]);
}
if (location.rgcData.poiList) {
for (BMKLocationPoi * poi in location.rgcData.poiList) {
NSLog(@"poi = %@, %@, %f, %@, %@", poi.name, poi.addr, poi.relaiability, poi.tags, poi.uid);
}
}
if (location.rgcData.poiRegion) {
NSLog(@"poiregion = %@, %@, %@", location.rgcData.poiRegion.name, location.rgcData.poiRegion.tags, location.rgcData.poiRegion.directionDesc);
}
}
}
单次定位方法
// 单次定位
- (void)singleLocationMethod
{
[self.locationManager requestLocationWithReGeocode:YES withNetworkState:YES completionBlock:self.completionBlock];
}
持续定位方法
// 持续定位
- (void)continuedLocationMethod
{
// 持续定位返回地址信息
[self.locationManager setLocatingWithReGeocode:YES];
[self.locationManager startUpdatingLocation];
}
didFinishLaunchingWithOptions调用单次定位或者持续定位方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
--------------------
其他初始化代码
--------------------
// 地图配置
[self setLocationConfig];
// 单次定位block
[self singleLocationBlock];
// 单次定位
[self singleLocationMethod];
return YES;
}
如果定位配置信息里面的 _locationManager.allowsBackgroundLocationUpdates = NO;（不允许后台定位）
- 成功获取定位信息
如果定位配置信息里面的 _locationManager.allowsBackgroundLocationUpdates = YES;（允许后台定位）
-
配置1个 出现报错，得不到定位信息

配置3个 出现报错，得不到定位信息
截屏2021-07-30 14.33.51.png 配置1或者3个都会出现报错，并且得不到定位信息

解决方法
方法1、Targets -> Siging&Capability - >Background Modes 勾选Location updates, 但是开启后台定位模式。此选项App审核会被拒，需要说明后台使用定位的原因
截屏2021-07-30 14.47.53.png
方法 1 请注意，程序切换到后台，如果是持续定位，打印台每过几秒就会地址打印信息
方法2、创建 CLLocationManager分类, pch文件直接导入即可
#import "CLLocationManager+Extension.h"
#import <objc/runtime.h>
@implementation CLLocationManager (Extension)
+ (void)load {
if ([UIDevice currentDevice].systemVersion.floatValue >= 9.0) {
method_exchangeImplementations(class_getInstanceMethod(self.class, NSSelectorFromString(@"setAllowsBackgroundLocationUpdates:")), class_getInstanceMethod(self.class, @selector(swizzledSetAllowsBackgroundLocationUpdates:)));
}
}
- (void)swizzledSetAllowsBackgroundLocationUpdates:(BOOL)allow {
if (allow) {
NSArray *backgroundModes = [[NSBundle mainBundle].infoDictionary objectForKey:@"UIBackgroundModes"];
if( backgroundModes && [backgroundModes containsObject:@"location"]) {
[self swizzledSetAllowsBackgroundLocationUpdates:allow];
} else {
NSLog(@"APP想设置后台定位，但APP的info.plist里并没有申请后台定位");
}
} else {
[self swizzledSetAllowsBackgroundLocationUpdates:allow];
}
}
@end
