Split View / drill down

Hi, I would like to create a drill down as done in mail. I found a nice tutorialhttp://www.iphonesdkarticles.com/2009/03/uitableview-drill-down-table-view.html. It worked fine for a navigation based template. I tried to modify it for a split view template. In this case the I got: terminating

NStoolbaritem and a custom view

For NSToolbarItem and a custom view, do you need to call the selector for the action or is that handled automatically? I think it's not handled automatically because I have to handle the mouse events to update the drawing so I assume by calling super, it won't invoke the action because I change

Re: Scroller With CATiledLayer Running out of Memory

I chose 1024 width so that it would at least cover the (landscape) width, and not have to redraw the same line multiple times. The optimized drawing requires some computation itself, so I figured 512 was a good compromise that would require three tiles max per screen. Font size can go up to 192 p

I have a very long text view (CoreText) for iPad. It a CATiledLayer, 1024 x 512 tiles. I'm doing optimized drawing (first to last line) in drawRect, which gets called for each tile. I have a vertical slider that appears when you tap the right side in order to fast (live) scroll when needed. I'm

Sometimes a word in your original language can have multiple translations, depending in the context. Where I work, we use symbolic keys so that we can allow for context-sensitive translations. Dave Sent from my iPhone On Aug 6, 2010, at 9:50 AM, Richard Somers wrote: > String table entrys h

I have a segmented control to do up and down pages, that lives in an NSToolbar. I'd like to make it so that up and down arrow select the 0 and 1 segment respectively. However, I don't see a "Key equivalent" in the object inspector... A little research shows that the fact that its in a toolbar

String table entrys have the following form. "Key1" = "Value1" There appears to be two different ways to approach naming the keys. The first way is to use a literal key where the key and value are equal for the primary language. /* Ask user a question. */ "Do you need help?"
