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

第1步 - 创建一个简单的基于视图的应用程序。

步骤2 - 选择项目文件，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。

第4步 - 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

第5步 - 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
