OliverLetterer / XCDUUID.m

Created January 26, 2013 17:05

With this gist, I, as a total assembly noob, am trying to understand the XCDUUID runtime hack (https://github.com/0xced/NSUUID/blob/1.0.1/NSUUID.m#L167-L221) to be able to use NSUUID on iOS < 6.0.

	@implementation XCDUUID

	+ (void) load
	{
	// query runtime if NSUUID class already exists, if so => done
	if (objc_getClass("NSUUID"))
	{
	return;
	}
