在iOS应用中集成Twitter和Facebook分享功能，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。
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请确保在实际操作时参考最新的官方文档，因为随着时间的推移，API可能会有变化和更新。尤其对于Facebook分享，在2018年之后，由于Facebook调整了API策略，直接分享至用户的时间线可能需要额外的审核和权限管理流程。
