类似于微信中的发送位置，拖拽重新定位，以及反编码，列表附近的位置。
思路就是将一个UIImageView固定在地图中间，每次更新位置，给UIImageView添加动画即可。
代码如下：
#import "FTBasicController.h" typedef void (^SelectBlock) (NSString *address,CLLocationCoordinate2D select); @interface FTUploadAddressController : FTBasicController @property(nonatomic, copy)SelectBlock selectBlock; @end
#import "FTUploadAddressController.h" #import "FTBMKPoiInfo.h" #import "FTPoiCell.h" @interface FTUploadAddressController ()<BMKMapViewDelegate,BMKLocationServiceDelegate,UITableViewDelegate,UITableViewDataSource,BMKGeoCodeSearchDelegate> @property(nonatomic,strong)BMKLocationService *locService;

@property(nonatomic,strong)UIImageView *loactionView; @property(nonatomic,strong)NSMutableArray *dataA; @property(nonatomic,strong)LxButton *poiBackBtn; @property(nonatomic,assign)CLLocationCoordinate2D selectedCoordinate;
