1. 首先在info.plist 文件中添加两个属性值 都为 YESNSLocationAlwaysUsageDescription   NSLocationWhenInUseUsageDescription2.实现 BMKLocationServiceDelegate，BMKGeoCodeSearchDelegate  这两个代理方法@interfaceMKLocationManager()- (void)getCurrentLocated:(CLLocationCoordinate2D)coordinate;- (void)stopLocating;@end@implementation MKLocationManager- (id)init{    self = [superinit];    if (self)    {        [UIApplicationsharedApplication].idleTimerDisabled =YES;        //设置定位精确度，默认：kCLLocationAccuracyBest        [BMKLocationServicesetLocationDesiredAccuracy:kCLLocationAccuracyNearestTenMeters];        //指定最小距离更新(米)，默认：kCLDistanceFilterNone        [BMKLocationServicesetLocationDistanceFilter:100.f];        _locService = [[BMKLocationServicealloc]init];        _locService.delegate =self;        [selfstartLocating];
