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

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 targets，然后在 choose frameworks 中添加 Social.frameworkk 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 −

实例


#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 −

实例


#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
