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
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.
