ios - Customizing MKAnnotationView only through subclassed MKMapView? -


i've tried both (mkmapview delegate):

-(void) mapview:(mkmapview *)mapview didaddannotationviews:(nsarray *)views {     (mkannotationview *annotationview in views)     {         annotationview.image = [uiimage imagenamed:@"itemtype2.png"];         annotationview.rightcalloutaccessoryview = [uibutton buttonwithtype:uibuttontypedetaildisclosure];         annotationview.canshowcallout = yes;     }         }

and (on vc has mkmapview):

[self.themapview addannotations:annotationsarray];  (id <mkannotation> itemannotation in self.themapview.annotations) {             mkannotationview *itemannotationview = [self.themapview viewforannotation:itemannotation];      itemannotationview.image = [uiimage imagenamed:@"itemtype2.png"];     itemannotationview.rightcalloutaccessoryview = [uibutton buttonwithtype:uibuttontypedetaildisclosure];     itemannotationview.canshowcallout = yes;      //[self.themapview setneedsdisplay]; }

whithout success on changing mkannotationview's appearance, appear simple red pins without disclosure buttons or anything....

is way of changing them through creating subclassed mkmapview , using - (mkannotationview *)viewforannotation:(id < mkannotation >)annotation ??? feel it's desnecessary create subclass changing annotations, why don't above methods work?

you don't need subclass set properties on mkannotationview.

you need implement viewforannotation delegate method , set properties there.

see this answer code example.

the change example use mkannotationview instead of mkpinannotationview.
