1、sqlite转NSDirectory或者NSArray（里面的每一个item都是NSDirectory）

NSMutableArray *results = [NSMutableArray array]; 

FMResultSet *appointmentResults = [[DataClass getDB] executeQuery:@"SELECT * FROM Appointments WHERE date = ?",currDateString]; 

while ([appointmentResults next]) 

{

 [results addObject:[appointmentResults resultDictionary]]; 

}
