I managed to get Xcode (running as a VM under Windows) pushing an XE2 build FireMonkey iOS HD app to my (jailbroken) iPhone after XE-script-prep (creating the Xcode folder), with a valid company certificate.

Anyway, faking the native cocoa controls seems a little seedy, but sticking a TToolbar (panel with standard iPhone gradient), a couple of TSpeedButtons (which h开发者_Python百科ave this curious V slope thing going on), and a TStringGrid and you're almost in the realms of basic iPhone app design.

Drop a TLabel on the TToolbar for a caption and straight away you'll want to change the colour, which there doesnt appear to be a property for. Yeah but it's all style (TLayout) driven now I hear you say, which is what I thought, but the style editor doesnt have a colour (color!?) property within TLayout or TText aspects of the Style Designer.

Shoe-horning a second question which is just as quick, I dropped a TStringGrid on there and thought I'd dynamically set the rows, so I created a string column, set the RowCount to 6, then set the

Cells[1, n] := 'Row ' + IntToStr(iLoop); 

...with no effect (I also tried Cells[0, n], in case it was a zero-based list).

Am I going mad?

Still stumped on connectivity (how do you talk to anything outside the iPhone!?), and the performance of spinning a 48x48 image with a TFloatAnimation on an iPhone 4 was quite frankly appalling. But I'm optimistic, we've got this far!


This works fine for me.

procedure TForm3.Button1Click(Sender: TObject);
var
  i: Integer;
begin
  for i:= 0 to 6 do
  begin
    StringGrid1.Cells[0,i] := 'Row:' + IntToStr(i);
  end;
end;

I noticed you had both nand iLoop wich one was the loop variable?

As to the color setting Roberts answer works designtime, if you want to set it in code you can do Label1.FontFill.Color := TAlphaColorRec.Beige;

better way.

Label1.ApplyStyleLookup;
Label1.FontFill.Color := TAlphaColorRec.White;

But I think the correct approach would be to give FontFill a setter function like:

function GetFontFill: TBrush;
begin
  if FNeedStyleLookup then ApplyStyleLookup;
  Result := FFontFill;
end;


To change the color of a Label you need to use the Style.

Right Click on the Component and select Edit|Custom Style...

Then expand the Tlayout to find and select the TText

Then adjust the Fill Property to change the color.
