描述：最近專案中用到了百度地圖獲取附近的店鋪資訊，改店鋪資訊需要用自定義PaoPaoView來展示，其設定步驟如下：

#import <MapKit/MapKit.h>

    [super viewWillAppear:YES];
    self.navigationController.navigationBarHidden = NO;
    _mapView.delegate = self; // 此處記得不用的時候需要置nil，否則影響記憶體的釋放
    _locService.delegate = self;
}

    //使用者位置追蹤(使用者位置追蹤用於標記使用者當前位置，此時會呼叫定位服務)

    _mapView.showsUserLocation = YES;                //設定為可以顯示使用者位置
    
    //設定經緯度
    SharedInfo *shared = [SharedInfo sharedDataInfo];
    float latitude = [shared.localLatitude floatValue];
    float longitude = [shared.localLongitude floatValue];
    
    coordinate.latitude = latitude;//緯度
    coordinate.longitude = longitude;//經度

    [BMKLocationService setLocationDistanceFilter:300.0f];

    BMKCoordinateRegion adjustedRegion = [_mapView regionThatFits:viewRegion];
