Good size for ipad icon-buttons?

[Danneman]

What's a good size for custom buttons (icons) in an ipad app? Ive been using anything between 24px to 34px on iphone, but Im guessing a bit bigger should probably be a better choice for the ipad?

What i do for a square button is...

I make a 600 by 600 image

then

i make my button saveit as a jpg or png

then

in put it in xcode the open interface builder put in a uiimage view resieze it to make the button image look good...

Then i drag in a Button change the alpha to 0.02 resize it to fit the button (so now the button is amost invisible and it shows the image under it)

then i add my actions build and go and there you have it a image button

Ok, that's a smart way of doing it

However, my project is based on a webview, so I have to use ready-to-use images correctly resized from the beginning, preferably, not to get a lot of overhead.

But won't images with the size 600x600 make the app very much larger? I mean, even though the image is resized by the interfacebuilder, the image is still left included in the project with its original size, right?

The only time I have that
Problem is if I try to make the button the image on my image view I think I have the mode set to scale to fill I believe and it doesn't resize them some times I havE used evenn bigger image like 1500 by 1500 sso I get good quality when I use them and this has worked for me since I started about 3-4 months ago
