iOS - Twitter 和 Facebook

---

Twitter已集成在iOS 5.0中，Facebook已集成在iOS 6.0中。我们的教程重点是使用 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.framework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 <Social/Social.h>
#import <Accounts/Accounts.h>
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

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

@end

步骤 5 - 更新ViewController.m如下 -

#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

当我们运行应用程序并单击 facebookPost 时，我们将得到以下输出 -

当我们点击 twitterPost 时，我们将得到以下输出 -
