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
