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 #import #import @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
