Swift basics: no foundation for swift

Swift basics: no foundation for swift

AMAP developers need to register an ak on the official website http://lbs.amap.com/console/, create a swift project, and then add an NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription in Info. plist.

Add the library and dependent library of AMAP to the project.

The required libraries are as follows:

Add header file

For details about the method, refer to the basic Swift-call the third-party OC project, add the following code in the Bridging-Header.h, so that we can call the AMAP-related interface

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

Basic Map implementation

Write map-related initialization and function development in the basic class. The interface is as follows: including positioning, data refresh, zoom-in, zoom-in, and add functions.
