• UITableViewCell checkmark change on select

  - by user333673

  Am I correct in thinking that to change the checkmark for "on" to "off", I must change the CellAccessoryType between none and checkmark on the didSelectRowAtIndexPath? Because I have done this but I have noticed the behaviour is not perfectly identical to like the checkmark cells on the auto lock settings on the iphone. Or is there some other way checkmarks are meant to be handled?

• How can I parse raw email source and extract the HTML part?

  - by Matthew Brindley

  In my iPhone app, I'm handed the raw source of an email, in RFC822 (or "eml") format. I'd like the HTML part of this message (if one exists). Rather than attempting to parse it out myself and converting escape chars and so on, I thought I'd check to see if anyone knows of an objective-c library to do this for me. In .NET, I've always used the Mailbee classes for anything email related, but I can't seem to find anything similar for cocoa.

• Hiding a navigation bar via scrolling (safari style)

  - by eagle

  After a page is loaded in Safari on the iPhone, when you begin scrolling down, the navigation bar is also scrolled out of view. When you scroll back up, the navigation scrolls back into view. I'm looking to implement this same behavior using a UIWebView underneath the UINavigationBar, but I'm guessing it should be possible with any UIScrollView descendant. How can this behavior be implemented?
