Trying to customize UITableViewCell with IB but having odd exception

In two classes, I've subclassed UITableViewCell in order to do some major customization. I'd like to use a Xib file to keep the amount of UI layout code to a minimum. I'm coming across an odd exception: if (!cell) { if (indexPath.row == 0) { cell = [[[SearchCellTop alloc]

Blocks and Methods...

I'm writing code in for iOS 5 Ok, in my async com class, I'm receiving a block in one method and want to execute it in the another method. I've concluded that I need to place the block in a property. The only way that has worked is via copy. Is this the conventional way to save a block? Th

NSRuleEditor templates?

Hello list, Forgive me if this has been asked and answered, but what does one do in XC4.2 to create the requisite rule editor templates? I find nothing useful in the docs on this topic, and the only example code used IB 3.0 to do this task. Help? Erik

Re: How to get the dispatch queue for the current thread's runloop?

Hi Jens, My understanding is that dispatch queues are tied to threads that are managed by the system and are separate from run loops. It's therefore non-sensical to ask for a runloop's queue. Regardless though, I think a better solution for you is a category on NSTimer. I use something like the f

This works: dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{}); On 2012-01-27, at 3:14 PM, Jens Alfke wrote: > I'm really used to using -performSelector:withObject:afterDelay: to make > something happen later. But I'd much rather use a block than a target/action.

How to get the dispatch queue for the current thread's runloop?

I'm really used to using -performSelector:withObject:afterDelay: to make something happen later. But I'd much rather use a block than a target/action. I can't find any API for this, however. Am I missing something? What I want is basically like PerformBlockAfterDelay(^{ …code here…}, 5.0

Re: How to open CMYK TIF in Cocoa?

I stand corrected as I have learned a lot more about this. They are premultiplied. Even though I got my feature working using libTiff, I like Jens idea of just walking thru the alpha data and manually setting the values. This would save having yet another lib linked in and seems to be a cleaner

Re: boundingRectWithSize problem?

Good thought Tim, but for some reason it doesn't work in this case (both on 10.6 & 10.7). As you would expect, it is size/font sensitive so I can get the same failure result (for the sample text given) with Times-Roman 11 point. Of the various text samples, it's only 1 in 10,000 or so that do
