Swift Foundation--Gold Map Practice (i)

The development of the German map needs to be http://lbs.amap.com/console/to register an AK, create a new Swift project, and then add a info.plist Nslocationalwaysusagedescription or nslocationwheninuseusagedescription.

A library of gold maps and a dependency library added to the project

The required libraries are as follows:

Add header file

See Swift basics in a specific way-call a third-party OC Project, add the following code to the Bridging-header.h, so we can invoke the map-related interfaces

#import <MAMapKit/MAMapKit.h> #import <AMapSearchKit/AMapSearchAPI.h>

Basic Map class implementation

The basic class is composed of map related initialization and function development, the interface is as follows: include positioning, data refresh, zoom in and out add, and function implementation.
