ios - Add Overlay to Mapview -


i have been doing ios dev few months. have map view couple of annotations pinned , can show users current location.

i haven been trying read through docs implement simple overlay using set of cllocationcoordinate2d draw out line (simple static route). has been struggle

my mkoverlayrenderer method doesnt seem running @ all. if not mistaking shouldn't need mkmapviewdelegate. trying implement mkoverlay delegate , have "@synthesize boundingmaprect;".

here code trying implement overlay

- (void)drawlineroute {     cllocationcoordinate2d purplepoints[2];     purplepoints[0] = cllocationcoordinate2dmake(28.541944, -81.382936);     purplepoints[1] = cllocationcoordinate2dmake(28.538447, -81.383096);      mkpolyline *purplepolyline = [mkpolyline         polylinewithcoordinates:purplepoints count:2];     purplepolyline.title = @"citrus bowl connection";  [self.mapview addoverlay:purplepolyline]; }  - (mkoverlayrenderer *)mapview:(mkmapview *)mapview viewforoverlay:  (id<mkoverlay>)overlay { if([overlay iskindofclass:[mkpolyline class]]) {     mkpolygonrenderer *polyrender = [[mkpolygonrenderer alloc] initwithoverlay:overlay];     polyrender.linewidth = 2;     polyrender.strokecolor = ovopurple;     return polyrender; }  return nil; } 

any or guidance appreciated. thank in advance.

there 2 different delegate methods:

it incorrect implement viewforoverlay returns mkoverlayrenderer.

bottom line, if need support ios versions prior ios 7, implement viewforoverlay returns mkoverlayview, not mkoverlayrenderer. if don't need support ios versions prior 7, not implement viewforoverlay @ all, rather implement rendererforoverlay returns mkoverlayrenderer.
