iOS - Twitter & Facebook

簡介

Twitter已經整合到iOS5.0，而Facebook已經被集成在iOS6.0中。本教程的重點是使用由蘋果提供的類，部署目標Twitter和Facebook分別爲：iOS5.0和iOS6.0。

涉及的步驟

1. 創建一個簡單的應用程序。

2. 選擇項目文件，然後選擇「目標」，然後選擇框架中添加Social.framework 和 Accounts.framework

3. 添加兩個按鈕名爲facebookPost 和 twitterPost，併爲他們創建 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

4. 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

輸出

現在，當我們運行應用程序並單擊「facebookPost」我們將得到下面的輸出。

當我們單擊「twitterPost」我們將得到下面的輸出。
