定位iOS百度地图反编码个人见解

iOS百度地图反编码个人见解

类似于微信中的发送位置拖拽从新定位以及反编码列表附近的位置。

百度地图拖拽更新位置.gif

思路就是将一个UIImageView 固定在地图中间每次更新位置给UIImageView添加劢画即可。

代码如下

#import "FTBasicControl ler.h"typedef void (^SelectBlock) (NSString *address,CLLocationCoordinate2D select);@interface FTUploadAddressControl ler : FTBasicControl ler

@property(nonatomic, copy)SelectBlock selectBlock;

@end

#import "FTUploadAddressControl ler.h"

#import "FTBMKPoiInfo.h"

#import "FTPoiCel l.h"
