ios - Xcode で OCUnit テストを実行中の EXC_BAD_ACCESS

Question

問題に行き詰まりました。OCUnit テストがあります。iOS 7 シミュレーターでは正常に実行できますが、iOS 6 シミュレーターでは EXC_BAD_ACCESS が発生します。

Xcode のスクリーンショットは次のとおりです。

と を使用OCMockitoしてOCHamcrestいます。

何が原因だったのか分かりますか？調べて原因を探っています。

テストケースのコード（少なくともログから）：

static NSString *const EMAIL = @"foo@example.com";
static NSString *const PASSWORD = @"secret";

@interface MDLoginViewControllerTest : SenTestCase

@end

@implementation MDLoginViewControllerTest {
    MDLoginViewController *controller;

更新: モックからメソッドを呼び出しているメソッドに問題があるようで、引数の 1 つは に強い参照を持つブロックselfです。

このメソッドのコードは次のとおりです。

- (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];
            }
        }
    }];
