IOS-Twitter和Facebook

---

简介

Twitter已经整合到iOS5.0，而Facebook已经被集成在 iOS 6.0中。本教程的重点讲解如何利用苹果提供的类在iOS5.0和iOS6.0中部署Twitter和Facebook。

实例步骤

1. 创建一个简单View based application

2. 选择项目文件，然后选择"targets(目标)"，然后在 choose frameworks（选择框架）中添加Social.framework 和 Accounts.framework

3. 添加两个名为facebookPost 和 twitterPost的按钮，并为他们创建 ibActions。

4. 更新 ViewController.h 如下

#import <Social/Social.h>

#import <Accounts/Accounts.h>

#import <UIKit/UIKit.h>



@interface ViewController : UIViewController



-(IBAction)twitterPost:(id)sender;

-(IBAction)facebookPost:(id)sender;



@end

5. 更新ViewController.m ，如下所示

#import "ViewController.h"



@interface ViewController ()



@end



@implementation ViewController



- (void)viewDidLoad

{

    [super viewDidLoad];

}



- (void)didReceiveMemoryWarning

{

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}



-(IBAction)facebookPost:(id)sender{

   

   SLComposeViewController *controller = [SLComposeViewController 

   composeViewControllerForServiceType:SLServiceTypeFacebook];

   SLComposeViewControllerCompletionHandler myBlock = 

   ^(SLComposeViewControllerResult result){

          if (result == SLComposeViewControllerResultCancelled)

          {                

            NSLog(@"Cancelled");                

          } 

          else                

          {

            NSLog(@"Done");

          }

          [controller dismissViewControllerAnimated:YES completion:nil];

        };

   controller.completionHandler =myBlock;        

   //Adding the Text to the facebook post value from iOS

   [controller setInitialText:@"My test post"];        

   //Adding the URL to the facebook post value from iOS

   [controller addURL:[NSURL URLWithString:@"http://www.test.com"]];        

   //Adding the Text to the facebook post value from iOS

   [self presentViewController:controller animated:YES completion:nil];    

}



-(IBAction)twitterPost:(id)sender{

    SLComposeViewController *tweetSheet = [SLComposeViewController 

    composeViewControllerForServiceType:SLServiceTypeTwitter];

    [tweetSheet setInitialText:@"My test tweet"];

    [self presentModalViewController:tweetSheet animated:YES];

}



@end
