So the iPhone 3GS compass (magnetometer)

[hotpace1]

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!

tap the location button twice.. once gets you your location 2nd does map orientation using the compass

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: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
@optional
-(int) h;
-(int) w;
-(void) seth : (int) a;
-(void) setw : (int) b;
@required
-(void) displayArea;
-(void) setx : (int) a;
-(void) sety : (int) b;
-(int) x;
-(int) y;
@end

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.

Wow...I just tried doing this and I completely agree. This is very annoying.
