不能使用OCMock存根方法

Question

我在一個objC項目上使用OCMock。

我有以下代碼：

DB_Account *Lena = [[DB_Account alloc] init]; 
    Lena.niceName = @"Lena"; 
    Lena.userId = @"Lena"; 
    id mockStorageManager = OCMClassMock([V4_StorageManager class]); 

    [[[mockStorageManager stub] andReturn:Lena] getAccountByDBId:@1]; 

    id mockDBNotificationManager = OCMClassMock([DBNotificationManager class]); 

    id partialV4DBNotificationManagerMock = OCMPartialMock([V4_DBNotificationManager manager]); 

    [[[mockDBNotificationManager stub] andReturn:(NotificationPolicy *)[NotificationPolicy Never]] getNotificationPolicy]; 

    [[[partialV4DBNotificationManagerMock stub] andReturn:mockDBNotificationManager] dbNotificationManager]; 
    BOOL shouldShow = [[V4_DBNotificationManager manager] showOnLoginExpired:Lena]; 

    assertThatBool(shouldShow,is(isFalse())); 

此代碼無法編譯上下面的行：

[[[mockDBNotificationManager stub] andReturn:(NotificationPolicy *)[NotificationPolicy Never]] getNotificationPolicy]; 

與此錯誤：

Error:(95, 5) multiple methods named 'getNotificationPolicy' found with mismatched result, parameter type or attributes 

此方法返回一個對象NotificationPolicy *類型，沒有其他類實現或聲明具有該名稱的方法。

出了什麼問題？

我不得不這樣做是爲了解決問題

[(DBNotificationManager*)[[mockDBNotificationManager stub] 
andReturn:[NotificationPolicy Never]] getNotificationPolicy];
