對iOS7的多個條件的pfquery的排序

Question

我想對多個條件的pfquery進行排序，下面的代碼只排序一列。請幫忙。

- (PFQuery *)queryForTable 
{ 
    PFQuery *query = [PFQuery queryWithClassName:self.parseClassName]; 
    [query whereKey:@"mStatus" equalTo:@"running"]; 
    [query orderByAscending:@"mName"]; 
    [query orderByAscending:@"mOrder"]; 
    return query; 
}

- (PFQuery *)queryForTable { 
    PFQuery *query = [PFQuery queryWithClassName:self.parseClassName]; 
    [query whereKey:@"mStatus" equalTo:@"running"]; 
    [query orderByAscending:@"mName"]; 
    [query addAscendingOrder:@"mOrder"]; 
    return query; 
}
