Getting the title of a Web View in Cocoa Touch

by

In an application I’m working on, I display a UIWebView with a navigation bar. I wanted to display the title of the web page in the navigation bar when I load a page, but there doesn’t appear to be any obvious way to do it.

There’s actually a very easy way to get the title (or any other property) of a page in a web view: stringByEvaluatingJavaScriptFromString:.

In this case, I use the delegate method webViewDidFinishLoad to obtain the page title and set the title of the navigation bar,

- (void)webViewDidFinishLoad:(UIWebView *)webView
{
    NSString* title = [webView stringByEvaluatingJavaScriptFromString: @"document.title"];
    navbar.title = title;
}

The result looks like this:

Douchebag teacher of the year

by

Via Slashdot:

A teacher came upon a student demonstrating Linux to other kids and handing out LiveCDs. The teacher confiscated the CDs and wrote an angry email to HeliOS’s founder, Ken Starks: “Mr. Starks, I am sure you strongly believe in what you are doing but I cannot either support your efforts or allow them to happen in my classroom. At this point, I am not sure what you are doing is legal. No software is free and spreading that misconception is harmful. … This is a world where Windows runs on virtually every computer and putting on a carnival show for an operating system is not helping these children at all. I am sure if you contacted Microsoft, they would be more than happy to supply you with copies of an older version of Windows and that way, your computers would actually be of service to those receiving them…” Starks pens an eloquent reply, which contains a factoid I have not seen mentioned before: “The fact that you seem to believe that Microsoft is the end all and be-all is actually funny in a sad sort of way. Then again, being a good NEA member, you would spout the Union line. Microsoft has pumped tens of millions of dollars into your union. Of course you are going to ‘recommend’ Microsoft Windows.”

New Blog Editor

by

Blogo is a very intriguing new blog editor with some very unique features, including a built-in Twitter client. It has a very nice rich text editing mode as well as a HTML mode.

Unfortunately the user interface is a lot more cluttered than MarsEdit and, at least for a long-time MarsEdit user, a lot less intuitive.

I really like the built-in Twitter client, but the editor looks un-Mac-like. I also find that switching between rich text & HTML modes inserts some extraneous tags. At least for now, I’m sticking with MarsEdit because it looks a lot more Mac-like and feels a lot smoother.

I started this post in Blogo but ended up using MarsEdit after it messed up the embedded images.
