Initialize Baidu map and location

Mapview = [[Bmkmapview alloc]initwithframe:cgrectmake (0, +, [UIScreen mainscreen].bounds.size.width, [UIScreen MAINSCREEN].BOUNDS.SIZE.HEIGHT-50)];

[Self.view Addsubview:mapview];

Locservice = [[Bmklocationservice alloc]init];

Set up Proxy

Locservice.delegate = self;

Start Locationservice

[Locservice Startuserlocationservice];

The following _mapview are Bmkmapview objects

Agent

#pragma mark-locationinfomation (user location information)

Update my location data

Geo Search service (converting latitude and longitude to address, city, etc., known as reverse geocoding)

Receive Reverse geocoding results

#pragma mark-configdelegate (set up agent and cancel agent)

Set up Proxy

-(void) Viewwillappear: (BOOL) animated

}

Remember to set nil when not in use, otherwise affect the release of memory

-(void) Viewwilldisappear: (BOOL) animated

Mapview.delegate = nil; When not in use, place nil

_searcher.delegate = nil;

}

#pragma mark-checknetwork (check network and authorization)

Check network status

-(void) Ongetnetworkstate: (int) Ierror

{

NSLog (@ "Networking success");

}

else{

#pragma mark-bmkmapviewdelegate (map callout and route color)

return polylineview;

}

return nil;

}

Open follow

Mapview.usertrackingmode = Bmkusertrackingmodefollow;

Mapview.showsuserlocation = yes;//Show positioning layer

It's not very good    to write a preservation role for yourself.
