- (uitableviewcell *)tableview:(uitableview *)tableview      cellforrowatindexpath:(nsindexpath *)indexpath { }

when debug project, it's never been called.then related codes , storyboard checked, nothing wrong, deleted pasted functions codes, , wrote codes word word; debug, run , it's been called.

the other pasted codes run , called. function had issue.

after all, studied issue, , cannot find why happened.

please, me solve "the paste codes cannot called".

thanks lot.

you have capitalization issue in method name. change tableview: tableview: 

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath

should this

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath

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.
