even though displays pin , want to, semantic issue , cant seem solve problem

if great thanks

heres code, problem in //brewmapviewcontroller.m error on line

myannotation *annotation = [[myannotation alloc] initwithdictionary:brewerydict];

you have put method signature - (id) initwithdictionary:(nsdictionary *) dict header file in order tell brewmapviewcontroller method exists:

/*myannotation.h*/ #import <foundation/foundation.h> #import <mapkit/mapkit.h> @interface myannotation : nsobject <mkannotation> { cllocationcoordinate2d coordinate; nsstring *title; nsstring *subtitle; nsstring *test; } @property (nonatomic, readonly) cllocationcoordinate2d coordinate; @property (nonatomic, copy) nsstring *title; @property (nonatomic, copy) nsstring *subtitle; @property (nonatomic, copy) nsstring *test; - (id) initwithdictionary:(nsdictionary *) dict; @end
