Question

I write my first iOS application and I read many tutorials about how to handle pictures for different screen sizes of vaious iPhone version.
But how can I handle the size (width) of textbox which is tied with the background image (the image is changed by izs name for the relevant iPhone version, but the textbox width)?

I hope that bunch of if statements in code isn’t the only way..

Thank you

If you’re setting up the textbox in Interface Builder, check out the Size helper (in the right-hand panel, this is the tab marked with a ruler icon), and look at the image labeled “autosizing”. You’ll see a box containing two arrows (vertical and horizontal), surrounded by four brackets (to the left, to the right, above, and below). The arrows (“springs”) represent the dimensions of the textbox itself – if they are solid, the textbox will adjust its size to fit a larger screen. The brackets (“struts”) represent the margins around the textbox – if they are solid, the textbox will maintain its position relative to the corresponding screen edges. Each of these arrows and brackets can be toggled on and off by clicking.
