我的应用程序已设置好,如果用户使用Oauth或Openid登录,则无需确认其电子邮件地址.但是,Devise仍在发送电子邮件确认.当我调用User.skip_confirmation时!我得到一个未定义的方法错误.我的模特:

class User < ActiveRecord::Base
  devise :database_authenticatable, :registerable, :recoverable, :rememberable, 
  :trackable, :validatable, :confirmable, :lockable, :token_authenticatable, :omniauthable

  attr_accessible :username, :email, :password, :password_confirmation, :remember_me
  validates_presence_of :username
  validates_uniqueness_of :username, :case_sensitive => false

  def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
    data = access_token.extra.raw_info
    if user = User.where(:email => data.email).first
      user
    else 
      #User.skip_confirmation!
      User.create!(:username => data.name, :email => data.email, :password =>    Devise.friendly_token[0,20]) 
    end
  end

  def skip_confirmation!
   self.confirmed_at = Time.now
 end
end

我的控制器:

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    @user = User.find_for_facebook_oauth(request.env["omniauth.auth"], current_user)
    @user.skip_confirmation!
    if @user.persisted?
      sign_in @user
      @fname = …

我正在尝试实现一个链表，所以我有一个带有头文件的 Node 类，如下所示：

@interface Node : NSObject

@property(nonatomic,assign)int data;
@property(nonatomic,strong) Node *right;
@property(nonatomic,strong) Node *left;

@end

然后在另一个类中，我分配它们，然后调用一个方法来销毁给定值的所有出现：

Node *node0 = [[Node alloc]init];
Node *node1 = [[Node alloc]init];
Node *node2 = [[Node alloc]init];
Node *node3 = [[Node alloc]init];
Node *node4 = [[Node alloc]init];
node0.data = 1;
node1.data = 2;
node2.data = 5;
node3.data = 5;
node4.data = 3;
node0.right = node1;
node1.right = node2;
node2.right = node3;
node3.right = node4;
node4.right = NULL;
[self removeNodeWithValue:node0 value:5];
NSLog(@"node %d, %d, %d, %d, …

我试图弄清楚这个合并排序实现有什么问题.当我连接剩下的左右数组时,我已经缩小了范围.在递归的第三个循环中,出现了问题.

-(NSArray *)mergeSort:(NSArray *)unsortedArray
{
  //unsortedArray is 4,2,6,5,3,9
  if ([unsortedArray count] < 2)
 {
    return unsortedArray;
 }
   int middle = ([unsortedArray count]/2);
   NSRange left = NSMakeRange(0, middle);
   NSRange right = NSMakeRange(middle, ([unsortedArray count] - middle));
   NSArray *rightArr = [unsortedArray subarrayWithRange:right];
   NSArray *leftArr = [unsortedArray subarrayWithRange:left];
   return [self merge:[self mergeSort:leftArr] andRight:[self mergeSort:rightArr]];
}

-(NSArray *)merge:(NSArray *)leftArr andRight:(NSArray *)rightArr
{
  NSMutableArray *result = [[NSMutableArray alloc]init];
  int right = 0;
  int left = 0;

  while (left < [leftArr count] && right < [rightArr …
