将Facebook SDK与旧版Xcode集成以支持iOS 5和iOS 6 [英] Integrating Facebook SDK for older versions of Xcode to Support both iOS 5 and iOS 6

问题描述

我仍在使用XCode 4.3.2和iOS 5.1基础SDK。我想要实现的是集成Facebook API for iOS 5.0+设备。只是基本功能，例如代表发布和获取基本用户信息。

I am still using XCode 4.3.2 and iOS 5.1 base SDK. What I want to achieve is to integrate Facebook API for iOS 5.0+ devices. Just basic features such as posting on behalf and getting basic user information.

我假设Facebook SDK在iOS 5上运行，将在iOS 6上运行，但我我不确定。

I am assuming that which ever Facebook SDK works on iOS 5, will work on iOS 6, but I am not sure about that.

作为Facebook整合的新手，任何人都可以对这个问题有所了解。 （因为我正在开发项目，所以不能升级XCode和iOS SDK）

As a rookie on Facebook Integration, can anybody shed some light on this issue. ( Since I am working on the project, upgrading the XCode and the iOS SDK is not an option)

• 我应该寻找哪个iOS SDK成？


• 我可以同时支持iOS 5和
  6，基本SDK 5.1和XCode 4.3吗？


• 是否有支持这两个iOS版本的API？


• Facebook集成的任何必须品？

• Which iOS SDK should I be looking into?
• Can I support both iOS 5 and 6, with base SDK 5.1 and XCode 4.3?
• Is there an API supporting both iOS versions?
• Any musts for Facebook Integration?

推荐答案

首先，您阅读了Facebook开发者发表的这篇文章

First of all you read this article published from Facebook developers

http://developers.facebook.com/docs/getting-started/facebook- sdk-for-ios /

在第1步中它也适用于xcode 4.3

in step 1 it will also work for xcode 4.3

你仔细阅读了所有的步骤n

you carefully read all steps one by one n implement

在第6步中你编写代码如下Facebook Btn Pressed

In step6 you write code as follow on where Facebook Btn Pressed

 - (IBAction)facebookBtnPressed:(id)sender
{


        // if it is available to us, we will post using the native dialog
        BOOL displayedNativeDialog = [FBNativeDialogs presentShareDialogModallyFrom:self
                                                                        initialText:[NSString stringWithFormat:@"Here U write code which u want to post on facebook"]
                                                                              image:[UIImage imageNamed:@"1.jpg"]
                                                                                url:[NSURL URLWithString:@""]
                                                                            handler:nil];

        if (!displayedNativeDialog)
        {
            NSString *shareStr = [NSString stringWithFormat:@"Here U write code which u want to post on facebook"];
            NSMutableDictionary* params = [[NSMutableDictionary alloc] initWithObjectsAndKeys:
                                           shareStr,@"description",
                                           @"sharelink", @"link",
                                           @"ImageName", @"picture",
                                           nil];

            [self performPublishAction:^{

                [FBRequestConnection startWithGraphPath:@"me/feed" parameters:params HTTPMethod:@"POST" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {

                    if (error)
                    {
                        NSLog(@"error in post");
                    }
                    else
                    {
                        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Post Successfully" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
                        [alert show];
                    }

                }];
            }];
        }
    //}

    //===set delagate in Viewcontroller.h of mySLComposerSheet
    [mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {
        NSString *output;

                output = @"Post Successfully";
                break;
            default:
                break;
        } //check if everything worked properly. Give out a message on the state.
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Facebook" message:output delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
        [alert show];
    }];
}
