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
