# 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
```
