iOS Twitter和Facebook

IOS-Twitter和Facebook

简介

Twitter已经整合到iOS5.0，而Facebook已经被集成在 iOS 6.0中。本教程的重点讲解如何利用苹果提供的类在iOS5.0和iOS6.0中部署Twitter和Facebook。

实例步骤

1. 创建一个简单View based application

2. 选择项目文件，然后选择"targets(目标)"，然后在 choose frameworks（选择框架）中添加Social.framework 和 Accounts.framework

3. 添加两个名为facebookPost 和 twitterPost的按钮，并为他们创建 ibActions。

4. 更新 ViewController.h 如下

#import

#import

#import

@interface ViewController : UIViewController

-(IBAction)twitterPost:(id)sender;

-(IBAction)facebookPost:(id)sender;

@end

5. 更新ViewController.m ，如下所示

#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
