I just re-factored this OCUnit code to Kiwi

Kiwi (new)

[[[user1Dict[@"highscores"] valueForKey:@"fb_id"] should] contain:fbId_user2];
[[[user2Dict[@"highscores"] valueForKey:@"fb_id"] should] contain:fbId_user1];

OCUnit (old)

NSDictionary *iphoneDictInIpadDict = nil;
NSDictionary *ipadDictInIphoneDict = nil;
for (NSDictionary *dict in user2Dict[@"highscores"])
{
	STAssertTrue(dict[@"fb_id"] != nil, @"Has to contain fb_id");
	if ([dict[@"fb_id"] isEqual:fbId_user1])
	{
		iphoneDictInIpadDict = dict;
	}
}
for (NSDictionary *dict in user1Dict[@"highscores"])
{
	STAssertTrue(dict[@"fb_id"] != nil, @"Has to contain fb_id");
	if ([dict[@"fb_id"] isEqual:fbId_user2])
	{
		ipadDictInIphoneDict = dict;
	}
}
STAssertTrue(iphoneDictInIpadDict != nil, @"Should have retrieved dictionary.");
STAssertTrue(ipadDictInIphoneDict != nil, @"Should have retrieved dictionary.");

Even without Kiwi, you could accomplish something also as short using MACollectionUtilities:

import "MACollectionUtilities.h"

STAssertTrue (MATCH (user2Dict[@"highscores"], [[obj objectForKey:@"fb_id"] isEqualTo:fbId_user1])), @"Should have retrieved dictionary.");
STAssertTrue (MATCH (user1Dict[@"highscores"], [[obj objectForKey:@"fb_id"] isEqualTo:fbId_user2])), @"Should have retrieved dictionary.");

Nice, thanks @iljaiwas :)
