ios - How do I display an arrow for MKPinAnnotationView.rightCalloutAccessoryView, like in Apple Maps? -

-

do initialize button image similar or there default values can use?

enter image description here

mkpinannotationview *newannotation = [[mkpinannotationview alloc] initwithannotation:annotation reuseidentifier:@"pinlocation"]; newannotation.animatesdrop = yes; newannotation.canshowcallout = yes; newannotation.rightcalloutaccessoryview = [uibutton buttonwithtype:uibuttontypedetaildisclosure];

you can show disclosure button following code:

- (mkannotationview *) mapview:(mkmapview *)mapview viewforannotation:(id <mkannotation>) annotation {        mkpinannotationview *newannotation = [[mkpinannotationview alloc]     initwithannotation:annotation reuseidentifier:@"pinlocation"];      newannotation.canshowcallout = yes;     newannotation.rightcalloutaccessoryview = [uibutton buttonwithtype:uibuttontypedetaildisclosure];   //for custom button  uiimage *btnimage = [uiimage imagenamed:@"arrow.png"]; uibutton *btn = [uibutton buttonwithtype:uibuttontypecustom]; [btn setimage:btnimage forstate:uicontrolstatenormal];    newannotation.rightcalloutaccessoryview = btn;  //try custom image on callout accessory view    newannotation.rightcalloutaccessoryview = [[uiimageview alloc] initwithimage:[uiimage imagenamed:@"arrow.png"]];      return newannotation; }

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
