Ios 在Xcode中运行OCUnit测试时EXC\u访问错误

我被这个问题困住了。我有视力测试。我可以在iOS 7模拟器上成功运行它们，但我在iOS 6模拟器上获得了EXC_BAD_访问权限

以下是Xcode的屏幕截图：

我使用的是

OCMockito

和

OCHamcrest

你知道是什么原因吗？我正在调查并找出原因

更新：

这里是测试用例的代码（至少来自日志）：

来自Xcode的更多图像：

更新： 看起来问题出在从mock调用方法的方法中，其中一个参数是block，它在

self

上有很强的引用

以下是此方法的代码：

- (void)requestDiscoveryWithEmail:(NSString *)email andPassword:(NSString *)password
{
    ...
    // store email / password on view
    _email = [email copy];
    _password = [password copy];

    [self.loginView showSpinner];

    [self.network discoveryWithEmail:email
        andPassword:password
        andCallback:^(NSDictionary *response, NSError *error) {
        // Hide the spinner
        [self.loginView hideSpinner];

        if (error) {
            [self showError:error];
        }
        else {
            if (![self isResponseComplete:response]) {
                _response = [response copy];
                [self.alertManager showAlertMessage:NSLocalizedString(@"We were unable to reach some services because maintenance or some issues", @"Unreachable services message")
                                      withTitle:NSLocalizedString(@"Issues happened", @" Issues happened title")
                                    andDelegate:self];
            }
            else {
               [self processDiscoveryResponse:response];
            }
        }
    }];
}

你能展示一些代码吗？你不能把错误缩小到一个方法吗？你能教我怎么做吗？试着单独运行测试，看看是哪一个导致崩溃！当我试图调用mock实例上的对象时，问题似乎出现了。调查！

- (void)requestDiscoveryWithEmail:(NSString *)email andPassword:(NSString *)password
{
    ...
    // store email / password on view
    _email = [email copy];
    _password = [password copy];

    [self.loginView showSpinner];

    [self.network discoveryWithEmail:email
        andPassword:password
        andCallback:^(NSDictionary *response, NSError *error) {
        // Hide the spinner
        [self.loginView hideSpinner];

        if (error) {
            [self showError:error];
        }
        else {
            if (![self isResponseComplete:response]) {
                _response = [response copy];
                [self.alertManager showAlertMessage:NSLocalizedString(@"We were unable to reach some services because maintenance or some issues", @"Unreachable services message")
                                      withTitle:NSLocalizedString(@"Issues happened", @" Issues happened title")
                                    andDelegate:self];
            }
            else {
               [self processDiscoveryResponse:response];
            }
        }
    }];
}
