Open-Source: NSBegin*AlertSheet(…) with ^Blocks

There’s NSBeginAlertSheet, NSBeginInformationalAlertSheet and NSBeginCriticalAlertSheet, so the * is a wild-card for all those functions.

What is this?

I’ve been growing more and more tired of always having to set up a callback-method (in the worst case, two, for didDismiss and didEnd) for NSBegin*AlertSheet(…) calls, like

– (void)alertSheet:(NSPanel *)panel endedWithCode:(NSInteger)returnCode contextInfo:(void *)info
{
 …code here…

Especially, since we have such a great thing like blocks where you can pass blocks of code as arguments to methods and functions, just like an Objective-C object.

So instead of having to set up callback methods for NSBegin*AlertSheet(…), I created ESSBegin*AlertSheet(…). Instead of callback @selectors, it takes blocks for didEnd and didDismiss callbacks.

I find it also makes for cleaner code having the callbacks right in the ESSBegin*AlertSheet(…) calls as you don’t lose the context of what’s happening before the call in my code.

Available for OS X Snow Leopard and up

Blocks were introduced with OS X Snow Leopard, so I assume (yes, I assume since I’ve only tested this on OS X Mountain Lion) it should run on Snow Leopard as well.

Today I released my first open source framework for OS X Lion – ESSVideoShare.

What is ESSVideoShare

It’s a framework for OS X Lion that makes it very easy to implement video publishing to these services:

YouTube, Vimeo, Facebook and Flickr

What you need

Import ESSVideoShare into your project, make sure ti’s being copied to your app’s bundle in a build copy phase.
And of course, for each service, you need an API key.

I explain the process of implementing ESSVideoShare step by step on its github page.

In-Depth

If you’re interested in how it all works, please head on over to the public github repository.

Support

If you have any questions or suggestions for improvement, be sure to let me know either through the comments below or by mail 🙂

Take care,

I received three (yes, I counted them) crash logs of flickery with this particular problem, so it’s not really common, but I still thought I should let you know what it’s about.

Apparently, when using NSOperationQueue and NSOperation on 10.5 there’s a chance an exception is thrown and the application will crash.

I’ve been checking on this for quite some time now and finally stumbled upon this blog post by Rogue Amoeba’s Mike Ash.
What he’s saying is that NSOperationQueue is buggy on 10.5 which causes applications to crash. This is really sad because it’s such a great tool for us developers.

I haven’t been able to work around this issue yet, however, I’ll keep working on it and see if I can do something about it, short of rewriting the whole application.

Fingers crossed.
