    So am I missing something? How do you use the compass within Googlemaps? I was expecting the maps to move around depending on which direction you were standing in? They seem to work exactly the same as on the 3G!

    I forgot which button you press, but from within the google maps app, I think it's the little radar icon, circle with crosshairs in it, tapping it twice will enable the compass and it will show you which direction you're pointing with a cone shape

    help me

    hello ! there.

    i am new to the objective c delelopement.

    for me objective c is like.

    but i have to learn it any how as it is part of my duty.

    so, i have a problem.

    problem is i can't set @required and @optional in my protocol file.

    i am using mingw32 from windowsxp & i am using gcc compiler.
    compiler gives erros something like following
    shape.h:2: error: stray '@' in program
    shape.h:3: error: syntax error before '-' token
    shape.h:7: error: stray '@' in program
    shape.h:8: error: syntax error before '-' token
    main.m: In function `main':
    main.m:11: warning: `rectangle' may not respond to `-displayArea'
    main.m:11: warning: (Messages without a matching method signature
    main.m:11: warning: will be assumed to return `id' and accept
    main.m:11: warning: `...' as arguments.)
    main.m:12: warning: `rectangle' may not respond to `-h'
    main.m:16:2: warning: no newline at end of file

    my original protocol file is as below - shape.h
    @protocol shape
    -(int) h;
    -(int) w;
    -(void) seth : (int) a;
    -(void) setw : (int) b;
    -(void) displayArea;
    -(void) setx : (int) a;
    -(void) sety : (int) b;
    -(int) x;
    -(int) y;

    haha dude you registered and posted to the wrong forum. i have no clue how you managed to end up so far off, but I am truly impressed, not by your development skills, but your ability to make me laugh.

    While the compass orientation is nice, I wish it would stick. For example I find my current location, tap the button again to swing around to the direction I'm facing, but as soon as I scroll the map to look down the road or whatever the view swings back to the default orientation. Pretty annoying.

    I think I've used that compass feature once so far, and that was when I first go the phone to play around with it..

    haha...I agree, that guy is totally lost. Kind of ironic that he posted on a thread talking about how to get a compass to work.
