核心數據sqlite文件已損壞

Question

我正在處理註銷的應用程序我正在刪除sqlite文件並登錄時我正在創建一個新的應用程序，但是在重新登錄並從服務器獲取數據我現在遇到一個神祕的問題，我不能因爲2周修復：

2013-04-29 07:05:09.107 APP[85958:1cd03] CoreData: sql: SELECT 0, t0.Z_PK, t0.Z_OPT, t0.ZACTION, t0.ZDISPLAYNAME, t0.ZENTITYNAMELIST, t0.ZFIELDCONSULTANTID, t0.ZKEY, t0.ZLASTUPDATETIME, t0.ZMESSAGE, t0.ZPATH, t0.ZPERIODMONTH, t0.ZPERIODYEAR, t0.ZREQUESTDURATION, t0.ZREQUESTNAME, t0.ZREQUESTSTARTTIME, t0.ZSTATE, t0.ZSTOREID, t0.ZTERRITORYID, t0.ZUPDATEDURATION, t0.ZUPDATESTARTTIME FROM ZSYNCREQUESTENTITY t0 WHERE t0.ZKEY = ? LIMIT 1 
2013-04-29 07:05:09.107 APP[85958:1cd03] CoreData: details: SQLite bind[0] = "TERRITORY_DATA" 
2013-04-29 07:05:09.108 APP[85958:1cd03] CoreData: annotation: Disconnecting from sqlite database due to an error. 
2013-04-29 07:05:09.166 APP[85958:1cd03] CoreData: error: (26) Fatal error. The database at /Users/admin/Library/Application Support/iPhone Simulator/6.0/Applications/C01FFF00-8530-4C8E-B954-AD9A70149972/Library/Application Support/APP/APP.sqlite is corrupted. SQLite error code:26, 'file is encrypted or is not a database' 

我使用MagicalRecord第三方來處理在背景方面的融合。我不確定是否可以成爲問題的原因

任何幫助將不勝感激？

謝謝。

試圖清除我的核心數據「數據庫」時，我收到了同樣的錯誤堆棧跟蹤。

Christian在你的問題上的評論爲我解決了這個問題。刪除我的NSPersistentStore後，我還清除了我們的文檔目錄。這會刪除sql日誌文件，這會爲我刪除錯誤。

NSPersistentStore *store = [ad.managedObjectContext.persistentStoreCoordinator.persistentStores lastObject]; 
NSError *error; 
NSURL *storeURL = store.URL; 
NSPersistentStoreCoordinator *storeCoordinator = ad.persistentStoreCoordinator; 
[storeCoordinator removePersistentStore:store error:&error]; 
[[NSFileManager defaultManager] removeItemAtPath:storeURL.path error:&error]; 
[self deleteFilesInDocumentsDirectory]; 


- (void)deleteFilesInDocumentsDirectory 
{ 
    NSString *folderPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 
    NSError *error = nil; 
    for (NSString *file in [[NSFileManager defaultManager] contentsOfDirectoryAtPath:folderPath error:&error]) { 
     [[NSFileManager defaultManager] removeItemAtPath:[folderPath stringByAppendingPathComponent:file] error:&error]; 
    } 
}
