Twitter已集成到iOS 5.0中,而Facebook已集成到iOS 6.0中。我们的教程侧重于使用Apple提供的类,Twitter和Facebook的部署目标分别是iOS 5.0和iOS 6.0。

涉及的步骤

步骤1-创建一个简单的基于视图的应用程序。

步骤2-选择您的项目文件,然后选择目标,然后在选择框架中添加Social.framewor k和Accounts.framework

步骤3-添加两个名为facebookPost和twitterPost的按钮,并为它们创建ibActions。

步骤4-更新ViewController.h如下-

#import 
#import 
#import 

@interface ViewController : UIViewController

-(IBAction)twitterPost:(id)sender;
-(IBAction)facebookPost:(id)sender;

@end

步骤5-如下更新ViewController.m-

#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
