Coordinate Conversion between Baidu navigation SDK and iOS navigation sdk

Coordinate Conversion between Baidu navigation SDK and iOS navigation sdk

Examples of code for converting coordinates of Baidu navigation iOS SDK. For more information, see.

 

// Navigation coordinate --------------> map coordinate

// Assume that the coordinate obtained from the navigation sdk is (116.304847, 40.025281)

// (1) construct the input parameter BNPosition required by the Conversion Function

BNPosition * naviPos = [[BNPosition alloc] init];

NaviPos. x = 116.304847;

NaviPos. y = 40.025281;


// Define output parameters

BMapPoint mapPoint = {0, 0 };


// Call the Conversion Function

BOOL ret = [BNTools ConvertBaiduNaviPoint: naviPos ToBaiduMapPoint: & mapPoint];


// Use the converted map coordinates

If (ret)

{

NSLog (@ "the navigation coordinates are converted into map coordinates. After the conversion, MapPoint = (% f, % f)", mapPoint. x, mapPoint. y );

}

Else

{

NSLog (@ "Conversion failed ");

}
