從sqlite中獲取數據時發生內存泄漏

Question

我寫了一個fetchAllFromDatabase從我的db中獲取數據。 的代碼是：

if ([tableName isEqualToString:kFavouriteStoresList]) { 
        NSMutableDictionary *dictFavStoreDetails = [[NSMutableDictionary alloc] init]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,0)] forKey:kFavouriteStoresList_ZipCode]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,1)] forKey:kFavouriteStoresList_StoreNumber]; // Leaking Memory 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,2)] forKey:kFavouriteStoresList_Address]; // memory leak 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,3)] forKey:kFavouriteStoresList_StoreName]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,4)] forKey:kFavouriteStoresList_City]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,5)] forKey:kFavouriteStoresList_State]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,6)] forKey:kFavouriteStoresList_Phone]; // Memory leak 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,7)] forKey:kFavouriteStoresList_Latitude]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,8)] forKey:kFavouriteStoresList_Longitude]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,9)] forKey:kFavouriteStoresList_sHrsMonToThu]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,10)] forKey:kFavouriteStoresList_sHrsFri]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,11)] forKey:kFavouriteStoresList_sHrsSat]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,12)] forKey:kFavouriteStoresList_sHrsSun]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,13)] forKey:kFavouriteStoresList_pHrsMonToThu]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,14)] forKey:kFavouriteStoresList_pHrsFri]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,15)] forKey:kFavouriteStoresList_pHrsSat]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,16)] forKey:kFavouriteStoresList_pHrsSun]; 
        [dictFavStoreDetails setObject:[NSString stringWithUTF8String:(char *) sqlite3_column_text(compiledStatement,17)] forKey:kFavouriteStoresList_StoreServicesList]; 

        [tempFetchArray addObject:dictFavStoreDetails]; 
        [dictFavStoreDetails release]; 
        dictFavStoreDetails = nil; 
       } 

在這裏，我對3個系得到一個內存泄漏（見在此定義3行的內存泄漏的評論）。誰能告訴我爲什麼會發生這種情況

你使用靜態分析儀嗎？如果案件仔細查看信息，有時泄漏不會放在正確的線路上。
