Question

I’ve been moving an alert view slightly higher so i can fit a keyboard on screen as well. I just do this by grabbing the frame of the alert and changing the Y after i have already shown the alert so that the frame variables are legit. This works fine on the simulator, but when I do this on the hardware, the alert starts at the correct position but then almost immediately jumps down to it’s original vertical center place. Is the UIAlertView position a fixed thing that isn’t supposed to change per the usability guidelines or am i just doing something incorrectly?

Thanks!

What OS are you trying this against? I got this to work on both the OS 3.0 Simulator and OS 3.0 Device:

UIAlertView * alert = [ [ UIAlertView alloc ] initWithTitle:@"Alert" message:@"Alert" 
                        delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil ];

alert.transform = CGAffineTransformTranslate( alert.transform, 0.0, 100.0 );

[ alert show ];

CGAffineTransformTranslate takes three arguments: the existing transform, an x transform, and a y transform. In the example I used, the alert view appeared 100 pixels higher than it normally would. Give this a try and see what happens.

Also, I’m pretty certain you can modify the frame before showing the alert as it likely sets up the alert’s frame in init to be the center of the entire screen by default.
