Function Documentation

AMapCoordinateConvert()

FOUNDATION_EXTERN CLLocationCoordinate2D AMapCoordinateConvert	(	CLLocationCoordinate2D	coordinate,
		AMapCoordinateType	type
	)

转换目标经纬度为高德坐标系，不在枚举范围内的经纬度将直接返回。

Converts the input coordinate to AMap coordinate system; coordinates outside the supported enum range are returned unchanged.

Parameters

coordinate	待转换的经纬度 Longitude and latitude to be converted
type	坐标系类型 coordinate system type

Returns

高德坐标系经纬度 Gaode coordinate system latitude and longitude

AMapDataAvailableForCoordinate()

FOUNDATION_EXTERN BOOL AMapDataAvailableForCoordinate

(

CLLocationCoordinate2D

coordinate

)

判断目标经纬度处是否有高德数据。输入参数为高德坐标系。此方法为粗略判断，在边界地区可能会不准确。

Determines whether AMap data is available at the specified coordinate. The input is expected in the AMap coordinate system. This is an approximate check and may be inaccurate near borders.

Parameters

coordinate

待判断的目标经纬度 Coordinate the target latitude and longitude to be determined

Returns

布尔值。YES:有数据，NO:没数据

Boolean value. YES: data available, NO: no data

AMapEmptyStringIfNil()

FOUNDATION_STATIC_INLINE NSString * AMapEmptyStringIfNil

(

NSString *

s

)

如果字符串为nil则返回空字符串

Returns an empty string if the input string is nil
