xcode4.5 - On xcode, how do I say the length of the screen -

-

i have image appear in middle of screen. when change ios simulator iphone 4s 5, image doesn't appear in middle of screen, appears more top.

i thinking there way like: uiimageview.center.y = length of screen/2

please let me know if there way that.

you going want screen dimensions first cgrect. can use cgrect screens height , width.

cgrect screensizerect = [[uiscreen mainscreen] bounds]; cgfloat width = screensizerect.size.width; cgfloat height = screensizerext.size.height;

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
