• What's the best way to have functions share an array in Objective-C?

  - by editor

  I understand that in Objective-C you declare an array in the header file and interact with it in a class. So far I'm adding things and fetching them fine within a single function. I'm new to the language however and can't figure out how to share that array across other functions. I'd like to initialize array data in my viewDidLoad and access it from various functions later on. Is this possible and if so what's the best way to do it?

• Replacing ’ character in PHP

  - by richard

  Hello, I'm having a hard time trying to replace this weird right single quote character. I'm using str_replace like this: str_replace("’", '\u1234', $string); It looks like I cannot figure out what character the quote really is. Even when I copy paste it directly from PHPMyAdmin it still doesn't work. Do I have to escape it somehow?

• Combine file transfer dialogs

  - by SamuelDavis

  I am considering upgrading my work computer to use windows 8 as the new file transferring feature seems very useful. Unfortunately after installing windows 8 on my home pc to test it out, the files are being transferred in separate dialogs as opposed to this image provided by microsoft. As I am transferring files constantly a single transfer dialog would make things much less confusing. Does anyone know what settings to change to make file transfers appear in the same window?
