objective c - Can Delphi XE4 import iOS ObjC Class ? ( Static Library *.a ) -


can delphi xe4 import ios objc class ? ( static library *.a )

objc code : test.a

// test.h --------------------------------------------------------------- #import <foundation/foundation.h> @interface mycalc : nsobject {    bool busy;   } - (int) calc : (int) value; @end   //  test.m -------------------------------------------------------------- #import "test.h" @implementation mycalc  -(int) calc:(int)value {     busy = true;     return ( value + 1);   } @end

delphi xe4 code "unit1.pas" testing

unit1;  interface  uses   system.sysutils, system.types, system.uitypes, system.classes,    system.variants,system.typinfo,   fmx.types, fmx.controls, fmx.forms, fmx.dialogs, fmx.stdctrls,   //   posix.dlfcn,   macapi.objectivec,macapi.objcruntime,   iosapi.cocoatypes,iosapi.foundation,iosapi.uikit,iosapi.coregraphics;  {$link libtest.a} // <-- objc static library (3 architectures included)                   //     compiled binary size same,                   //     or without "$link libtest.a" lines.  type   //   mycalc = interface(nsobject)    ['{12891142-0f45-410d-a9ef-212f1ae23294}'] // unique guid    function  test(value : integer) : integer; cdecl;    end;    mycalcclass = interface(nsobjectclass)    ['{42891142-0f45-410d-a9ef-212f1ae23295}'] // unique guid    end;    //the tocgenericimport maps objc classes delphi interfaces    // when call create of tobjc_testclass   tmycalcclass = class(tocgenericimport<mycalcclass, mycalc>) end;    // -------------------------------------------------------------------------   tform1 = class(tform)     button1: tbutton;     procedure button1click(sender: tobject);   private   public   end;  var   form1: tform1;  implementation  {$r *.fmx}  procedure tform1.button1click(sender: tobject);  var   occalc : mycalc;   rtn    : integer;   handle : integer; begin  handle := dlopen('libtest.a',rtld_lazy); // ## q2 : right ?  occalc := tmycalcclass.create;           // ## q3 : error :                                           //          can't found objc class mycalc    rtn := occalc.test(100);                    button1.text := 'rst:' + inttostr(rtn); end;  end.

i rewrite code lars' advice xe4 ( firemonkey + ios static library) , pascal conversion objective c class?, compiling ok.

but, after running program in ipad3 device, when press button, shows "objectivec class myclac cound not found"

my questions are

q1. right syntax xe4 & ios static library ?

q2. / wihtout line {$link libtest.a} compiled size same always. what's wrong in code ?

q3. know ios app can't use static library except apple library. so, dlopen not required. right ?

always thanks

simon, choi

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
