当从命令行运行 OCUnit 测试时，我无法弄清楚为什么钥匙串访问失败。
为了继续我的测试，我在我的单元测试目标中添加了一个 hacktastic 类别：

#import "SFHFKeychainUtils+UnitTestHacks.h"
static NSMutableDictionary *fakeKeyChainHolder;
@implementation SFHFKeychainUtils (UnitTestHacks)
+ (NSMutableDictionary *)fakeKeyChainForServiceName:(NSString *)serviceName {
if (nil == fakeKeyChainHolder) {
fakeKeyChainHolder = [NSMutableDictionary dictionary];
}
NSMutableDictionary *fakeKeyChain = [fakeKeyChainHolder objectForKey:serviceName];
if (nil == fakeKeyChain) {
fakeKeyChain = [NSMutableDictionary dictionary];
[fakeKeyChainHolder setObject:fakeKeyChain forKey:serviceName];
}
return fakeKeyChain;
}
#pragma clang diagnostic push

请注意，这不是一个好的解决方案，而是让单元测试工作直到找到更好的解决方案的变通方法。
