    - (ibaction)nextbtn:(id)sender    {         nslog(@"click");    } 

i have used above code not working please tell me i'm doing wrong how resolve issue.

thanks in advance.

it not working because mapview still handles touch event. add detailview in the:

- (mkannotationview *)mapview:(mkmapview *)mapview viewforannotation:(id <mkannotation>)annotation  {      if ([annotation iskindofclass:[mkuserlocation class]])         {             return nil;         }      static nsstring *reuseidentifier = @"your_identifier";      mkannotationview *view = [mapview dequeuereusableannotationviewwithidentifier:reuseidentifier];     if (view == nil)     {         view = [[mkannotationview alloc] initwithannotation:annotation reuseidentifier:reuseidentifier];         view.image = [uiimage imagenamed:@"your_annotaion_image.png"];     }       view.canshowcallout = yes;       uibutton* rightbutton = [uibutton buttonwithtype:uibuttontypedetaildisclosure];      [rightbutton addtarget:self action:@selector(showdetails:) forcontrolevents:uicontroleventtouchupinside];      view.rightcalloutaccessoryview = rightbutton;       uiimageview *icon = [[uiimageview alloc] initwithimage:[uiimage imagenamed:@"your_icon_image"]];      view.leftcalloutaccessoryview = icon;       return view;     } 

and can call:

-(void)showdetails:(uibutton*)button {    //do stuff here } 

there absolutely no need build annotation callout view yourself, change design of default one.
