携手创造，共同生长！这是我参与「日新计划 8 月更文挑战」的第5天，点击查看活动概况

导言

需求布景：收款页面需求恳求IP定位API获取经纬度，因为高德的API的库不准确（没有实时更新），运用公司决议换腾讯API。

自己推荐app侧的SDK定位运用高德，因为高德SDK定位更准确，过错信息也更具体。

app侧运用定位的相关功用：

  1. 商户进件APP： 商户概况的从头定位，修改进件信息时的商户地址定位、支付终端绑定的从头定位、新增拜访记载的定位、新增/修改企业的企业地址定位

  2. 商户端APP： 终端管理的设备定位、店肆定位。

注意：仅当TencentLBSRequestLevel为TencentLBSRequestLevelPoi有回来值，否则为空。

/**

 *  仅当TencentLBSRequestLevel为TencentLBSRequestLevelPoi有回来值，否则为空
 */
@property (nonatomic, strong, nullable) NSArray<TencentLBSPoi*> *poiList;

过错信息

typedef NS_ENUM(NSUInteger, TencentLBSLocationError) {
    TencentLBSLocationErrorUnknown = 0,                 //!< 过错码，表明现在方位不知道，可是会一直测验获取
    TencentLBSLocationErrorDenied = 1,                  //!< 过错码，表明定位权限被禁止
    TencentLBSLocationErrorNetwork = 2,                 //!< 过错码，表明网络过错
    TencentLBSLocationErrorHeadingFailure = 3,          //!< 过错码，表明朝向无法承认
    TencentLBSLocationErrorOther = 4,                   //!< 过错码，表明不知道过错
};

1.2 高德SDK

  1. 增加依赖 pod 'AMapLocation', '2.6.7'
  2. 导入头文件：“
- (void)setuprequestLocationWithAMapLocatingCompletionBlock:(AMapLocatingCompletionBlock)completionBlock{
    self.block =completionBlock;
    self.location = [[AMapLocationManager alloc]init];
    self.location.delegate = self;
    [SVProgressHUD showWithStatus:@"定位中.."];
    if (@available(iOS 14.0, *)) {
        self.location.locationAccuracyMode = AMapLocationFullAndReduceAccuracy;
    } else {
        // Fallback on earlier versions
    }
    [self.location setDesiredAccuracy:kCLLocationAccuracyHundredMeters];
    //   定位超时时刻，最低2s，此处设置为2s
    self.location.locationTimeout = 2;
    //   逆地舆恳求超时时刻，最低2s，此处设置为2s
    self.location.reGeocodeTimeout = 2;
    [self.location requestLocationWithReGeocode:YES completionBlock:^(CLLocation *location, AMapLocationReGeocode *regeocode, NSError *error) {
            [SVProgressHUD dismiss];
        if(completionBlock){
            completionBlock(location,regeocode,error);
        }
    }];
}

过错信息分析

///AMapLocation errorCode
typedef NS_ENUM(NSInteger, AMapLocationErrorCode)
{
    AMapLocationErrorUnknown = 1,               ///<不知道过错
    AMapLocationErrorLocateFailed = 2,          ///<定位过错
    AMapLocationErrorReGeocodeFailed  = 3,      ///<逆地舆过错
    AMapLocationErrorTimeOut = 4,               ///<超时
    AMapLocationErrorCanceled = 5,              ///<取消
    AMapLocationErrorCannotFindHost = 6,        ///<找不到主机
    AMapLocationErrorBadURL = 7,                ///<URL反常
    AMapLocationErrorNotConnectedToInternet = 8,///<连接反常
    AMapLocationErrorCannotConnectToHost = 9,   ///<服务器连接失利
    AMapLocationErrorRegionMonitoringFailure=10,///<地舆围栏过错
    AMapLocationErrorRiskOfFakeLocation = 11,   ///<存在虚拟定位风险
    AMapLocationErrorNoFullAccuracyAuth = 12,   ///<准确定位权限反常
};

II 判别经纬度是否在国内

2.1 判别经纬度是否在国内

TencentLBSLocationUtils
/**
 *  判别经纬度是否在国内
 *  
 */
+ (BOOL) isInRegionWithLatitude:(double)latitude longitude:(double)longitude;

blog.csdn.net/z929118967/…

封装


/**
 根据经纬度判别 是否在大陆地区
 */
+ (BOOL)inChineseMainlandWithCLLocation:(CLLocation *)location province:(NSString *)province{
    //coordinate.longitude
    if([TencentLBSLocationUtils isInRegionWithLatitude:location.coordinate.latitude longitude:location.coordinate.longitude]){
        // 扫除 香港、澳门、台湾
        if([province isEqualToString:@"香港特别行政区"] || [province isEqualToString:@"澳门特别行政区"] || [province isEqualToString:@"台湾"]){
            return NO;
        }else{
            return YES;
        }
    }else{//其他地区
        return NO;
    }
    return YES;
}

2.2 根据定位回来信息判别当时方位的行政区

/**
 *  回来当时方位的行政区划, 0-表明中国大陆、港、澳, 1-表明其他
 */
@property (nonatomic, assign) NSInteger areaStat;

III 封装定位SDK，一致数据模型

为了便于灵敏切换，新增定位一致进口，用于封装腾讯SDK和高德SDK，便于灵敏切换。

        [CRMLBSManager singleLocationIsShowError:YES WithcompletionBlock:^(CRMLBSLocationModel * _Nonnull location) {
            if(location.error){
                return;
            }
            if(!location.isInRegion){
                [SVProgressHUD showInfoWithStatus:@"您最新定位不在支撑范围内！"];
                return;
            }            
                    weakSelf.locationView.adressLab.text = location.address;
        }];
    }];

3.1 定位数据模型

@interface CRMLBSLocationModel : NSObject
/**
 *  回来当时方位的CLLocation信息
 */
@property (nonatomic, strong) CLLocation *location;
/**
 是否在国内，扫除港、澳、台
 */
@property (nonatomic, assign) BOOL isInRegion;
/**
 *  回来当时方位的地址
 */
@property (nonatomic, copy, nullable) NSString *address;
/**
 *  回来当时方位的省份
 */
@property (nonatomic, copy, nullable) NSString *province;
/**
 *  回来当时方位的大街
 */
@property (nonatomic, copy, nullable) NSString *street;
/**
 *  回来当时方位的大街编码
 */
@property (nonatomic, copy, nullable) NSString *street_no;
///爱好点名称
@property (nonatomic, copy) NSString *POIName;
@property (nonatomic, strong) NSError  *error;
@end

3.2 封装腾讯SDK的定位数据

/**
 isShowError: 发生过错是否展示提示语
 completionBlock： 定位回调
 */
+ (void)singleLocationIsShowError:(BOOL)isShowError WithcompletionBlock:(void (^)(CRMLBSLocationModel * _Nonnull location))completionBlock{
    [ERPLBS.shareERPLBS SingleLocation:^(TencentLBSLocation * _Nullable location, NSError * _Nullable error) {
        if ([SVProgressHUD isVisible]) {
            [SVProgressHUD dismiss];
        }
        CRMLBSLocationModel *model = [CRMLBSLocationModel new];
        if(error){//TencentLBSLocationError
            NSLog(@"locError:{%ld - %@};", (long)error.code, error.localizedDescription);
            if(isShowError){
                NSString *errorInfo = error.userInfo[@"NSLocalizedDescription"];
                errorInfo=errorInfo?errorInfo:@"定位失利请从头再试!";
                [SVProgressHUD showErrorWithStatus:errorInfo];
                //           [self showHUDMessage:errorInfo];
            }
            model.error = error;
            if(completionBlock){
                completionBlock(model);
            }
            return;
        }
        // 定位成功
        if (!location)
        {
            if(completionBlock){
                completionBlock(model);
            }
            return;
        }
        NSLog(@"location:%@", location);
        model.street = location.street;
        model.street_no = location.street_no;
        model.address= location.address;
        model.location = location.location;//经纬度
        model.POIName =[location.poiList.firstObject name];//[ERPLBS POInamebyArr:location.poiList]
        model.province = location.province;//
        // 判别是否在大陆 areaStat
        model.isInRegion= [ERPLBS inChineseMainlandWithCLLocation:location.location province:location.province];
        if(completionBlock){
            completionBlock(model);
        }
    }];
}

3.3 封装高德SDK的定位数据

+ (void)singleLocation4AMapIsShowError:(BOOL)isShowError WithcompletionBlock:(void (^)(CRMLBSLocationModel * _Nonnull location))completionBlock{
    [[ProjectMethod shareProjectMethod] SingleLocation:^(CLLocation *location, AMapLocationReGeocode *regeocode, NSError *error) {

        }
        CRMLBSLocationModel *model = [CRMLBSLocationModel new];
        if(error){//AMapLocationErrorCode
            NSLog(@"locError:{%ld - %@};", (long)error.code, error.localizedDescription);
            if(isShowError){
                NSString *errorInfo = error.userInfo[@"NSLocalizedDescription"];
                errorInfo=errorInfo?errorInfo:@"定位失利请从头再试!";
                [SVProgressHUD showErrorWithStatus:errorInfo];
                //           [self showHUDMessage:errorInfo];
            }
            model.error = error;
            if(completionBlock){
                completionBlock(model);
            }
            return;
        }
        // 定位成功
        if (!location)
