在iOS 5和6中使用Facebook实现登录 [英] Implement Login with Facebook in iOS 5 and 6

问题描述

这个问题看起来很重要，你们有50％是重复的，因为我没有找到任何好的答案。

让我把我的问题分成三部分。 / p>

目前情况：
我已经通过电子邮件，出生日期，性别和邮政编码。

这是非常好的工作。我也在iOS 5和6中实现了Facebook和Twitter的共享功能
但是现在我想用Facebook和Twitter进行实现，例如

，如下面的示例屏幕所示：

有什么问题：
我想知道如何在iOS 5中使用Facebook实现登录。twitter与ios 5和6，Facebook与iOS 6，所以这不是很大的（现在我认为）。我已经为iOS 5和Android推出了Twitter和Twitter的共享功能6.所以我需要做些什么来实现登录。

我得到的回应是：
正如我所说，我需要注册时的电子邮件，出生日期，性别和邮政编码。
如果我使用Facebook和Twitter进行登录，我该如何获取这些信息。
如果用户没有给出或阻止此社交网站的信息，该怎么办？

谢谢.......

解决方案

这是我在应用程序中如何实现这个功能：

1. 从此处下载适用于iOS的Facebook SDK




2. 在您的 AppDelegate.h 中创建Facebook对象的属性。

     #import< UIKit / UIKit.h> 
    #importFacebook.h
    
    @interface OutpearAppDelegate：NSObject< UIApplicationDelegate> {
    UIWindow * window; 
    IBOutlet UINavigationController * navigationController; 
   } 
    
    @property（非原子，保留）IBOutlet UINavigationController * navigationController; 
    @property（非原子，保留）IBOutlet UIWindow *窗口; 
    @property（非原子，保留）Facebook * facebook; 
    +（DemoAppDelegate *）getAppDelegate; 
     




3. 在您的 AppDelegate.m 写这个：

    综合Facebook; 
     

   并在您的 applicationDidFinishLaunching 方法中写下：

     //使用应用程序ID初始化Facebook 
    facebook = [[Facebook alloc] initWithAppId：FB_APP_KEY andDelegate：nil]; 
    //这里FB_AP_Key是您的Facebook应用程序密钥
     

   并发布在 dealloc




4. 您要在哪里登录Facebook功能：

      - （void）loginWithFacbookIdClicked 
    {
    [DemoAppDelegate getAppDelegate] .facebook.sessionDelegate = self ; 
    
    if（isInternetAvailable）
    {
    if（[[DemoAppDelegate getAppDelegate] .facebook isSessionValid]）
    {
    // [facebookIntegration getUserFacebookPersonalInfo]; 
    NSLog（用户已经登录了Facebook）; 
   } 
    else 
    {
    [[DemoAppDelegate getAppDelegate] .facebook authorize：[NSArray arrayWithObjects：@read_stream，
    @publish_stream，
    @email，
    @user_birthday，
    @friends_about_me，
    @friends_activities，
    @friends_likes，
    nil]]; 
   } 
   } 
    else 
    {
    NSLog（无Internet连接）; 
   } 
   } 
     




5. 登录后，Facebook SDK委托方法被自动调用。在委托方法中做你的东西。

      - （void）fbDidLogin 
    {
    NSLog（ Facebook的）; 
    //你的逻辑在这里。 
   } 
    
     - （void）fbDidNotLogin：（BOOL）已取消
    {
    DLog（@登录取消）; 
   } 
    
     - （void）fbDidExtendToken：（NSString *）accessToken expiresAt :( NSDate *）expiresAt 
    {
    
   } 
    
     - （void）fbSessionInvalidated 
    {
    
   } 
    
     - （void）fbDidLogout 
    {
    
   } 
     




This question look duplicate and ye it is 50% duplicate because there is no good answer I found any where.

let me divide my question in three part.

Current Situation: I have implemented sign up screen with Email, Date of birth, Gender and Zipcode.
This is working very nice. I have also implement share feature in facebook and twitter in iOS 5 and 6
But now I want to implement it with facebook and twitter like
shown in following example screen:

What is problem: I want to know how can I implement login with facebook in iOS 5. twitter is integrated with ios 5 and 6, Facebook with iOS 6 so that is not big deal (right now I think so). I have already implemented share feature for both twitter and facebook for iOS 5 & 6. so what more I need to do to implement login.

What I get in response: As I said I need Email, Date of birth, Gender and Zipcode at time of signup. How can I get this information if I use login with facebook and twitter. What should I do if user have not given or block this information of this social site.

Thanks.......

解决方案

Here is how I implemented this feature in my app:

1. Download the Facebook SDK for iOS from here

2. In your AppDelegate.h make a property of the Facebook object.

   #import <UIKit/UIKit.h>
   #import "Facebook.h"
   
   @interface OutpearAppDelegate : NSObject <UIApplicationDelegate> {
       UIWindow *window;
       IBOutlet UINavigationController *navigationController;        
   }
   
   @property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
   @property (nonatomic, retain) IBOutlet UIWindow *window;
   @property (nonatomic, retain) Facebook *facebook;
   +(DemoAppDelegate*)getAppDelegate;
   

3. In your AppDelegate.m write this:

   synthesize facebook;
   

   and in your applicationDidFinishLaunching method write this:

   // Initialize Facebook with app ID
   facebook=[[Facebook alloc]initWithAppId:FB_APP_KEY andDelegate:nil];
   //here FB_AP_Key is your Facebook application key
   

   and release facebook in dealloc

4. Where you want to login with Facebook write this function:

   - (void)loginWithFacbookIdClicked
   {
       [DemoAppDelegate getAppDelegate].facebook.sessionDelegate=self;
   
       if(isInternetAvailable)
       {
           if([[DemoAppDelegate getAppDelegate].facebook isSessionValid])
           {
               //[facebookIntegration getUserFacebookPersonalInfo];
                NSLog("User already logined with facebook");
           }
           else
           {
               [[DemoAppDelegate getAppDelegate].facebook authorize:[NSArray arrayWithObjects:@"read_stream",
                                    @"publish_stream",
                                    @"email",
                                    @"user_birthday",
                                    @"friends_about_me",
                                    @"friends_activities",
                                    @"friends_likes",
                                    nil]];
           }
       }
       else
       {
          NSLog("No Internet Connection");
       }       
   }
   

5. After login, the Facebook SDK delegate methods are automatically called. Do your stuff in delegate methods.

   - (void)fbDidLogin
   {
      NSLog("Logged into Facebook");
      // Your logic goes here.   
   }
   
   -(void)fbDidNotLogin:(BOOL)cancelled
   {
       DLog(@"Login Cancelled");
   }
   
   -(void)fbDidExtendToken:(NSString *)accessToken expiresAt:(NSDate *)expiresAt
   {
   
   }
   
   -(void)fbSessionInvalidated
   {
   
   }
   
   -(void)fbDidLogout
   {
   
   }
