　　代码10，HCIsCollectionHavingInAnyOrder实现

 

(BOOL)matches:(id)item
{
NSUInteger index = 0;
BOOL matched = (0 >= [self.matchers count]);
for (id matcher in self.matchers)
{
if ([matcher matches:item]) {
[self.matchers removeObjectAtIndex:index];
matched = YES;
return YES;
}
++index;
}
return matched;
}

　　代码11，更新过的matches:方法
　　(void)testAddConfig
　　{
　　[UMNavigationController setViewControllerName:@"ViewControllerA" forURL:@"um://
　　viewa2"];
　　NSMutableDictionary *config = [UMNavigationController config];
　　HC_assertThat([config allKeys]，
　　HC_hasInAnyOrder(HC_equalTo(@"um://viewa2")， nil));
　　GHAssertEqualStrings(config[@"um://viewa2"]， @"ViewControllerA"，
　　@"config set error.");
