objective c - IOS custom pin is not showing -

i trying show image instead of default red pin source location , image destination location.

- (void) sourcemarker:(mkplacemark * ) homeloc { mkannotationview *point = [[mkannotationview alloc] init];  mkpointannotation *ml = point.annotation;  ml.coordinate = homeloc.coordinate;  ml.title = @"home";  point.image = [uiimage imagenamed:@"home.png"]; point.canshowcallout = yes;  [self.mapview addannotation:ml]; } 

as suggested apple doc annotating maps. 1 has create custom annotation class, please refer following code.

myannotation.h

@interface myannotation : nsobject<mkannotation> { cllocationcoordinate2d coordinate; nsstring *title; nsstring *subtitle; nsstring *type;  }   @property (nonatomic, assign) cllocationcoordinate2d coordinate;  @property (nonatomic, copy) nsstring *title;  @property (nonatomic, copy) nsstring *subtitle;  @property (nonatomic, copy) nsstring *type; @end 

myannotation.m

@implementation myannotation   @synthesize coordinate;   @synthesize title;   @synthesize subtitle;   @synthesize type;  @end 

yourviewcontroll.m - showing map.

create annotation , set type property

myannotation *ann = [[myannotation alloc] init]; offann.coordinate = offlocation.coordinate; offann.title = @"my office"; offann.type = @"office"; [_mapview  removeannotation: offann]; [_mapview addannotation: offann];     - (mkannotationview *)mapview:(mkmapview *)mapview viewforannotation:(id <mkannotation>)annotation { nslog(@"viewforannotation called"); if ([annotation iskindofclass:[myannotation class]]) {     myannotation *myann=(myannotation *)annotation;      mkannotationview *pinview = (mkannotationview*)[self.mapview dequeuereusableannotationviewwithidentifier:@"myannotation"];     if (!pinview)     {         pinview = [[mkannotationview alloc] initwithannotation:annotation reuseidentifier:@"myannotation"];         //pinview.animatesdrop = yes;         pinview.canshowcallout = yes;         pinview.calloutoffset = cgpointmake(0, 4);      } else {         pinview.annotation = annotation;     }     if([myann.type  isequal: @"office"]) {         pinview.image = [uiimage imagenamed:@"office.png"];     }     return pinview; } return nil; }
