使用Facebook SDK 3.1支持iOS 5和iOS 6 [英] Supporting both iOS 5 and iOS 6 with the Facebook SDK 3.1

问题描述

我有一个应用程序，目前支持使用旧的Facebook SDK for iOS通过提要对话框发布到Facebook。

I have an app that currently supports posting to Facebook through the feed dialog using the old Facebook SDK for iOS.

更新到适用于iOS的Facebook SDK 3.1后，似乎我可以：

After updating to the Facebook SDK 3.1 for iOS, it seems that I can either:

1. 使用旧式API（ Facebook.h ，实例化 Facebook ，调用对话框：... ）


2. 或使用新样式API（ FacebookSDK.h ，使用共享 FBSession ，原生对话框）

1. use the old style API (Facebook.h, instantiate a Facebook, call dialog:...)
2. or use the new style API (FacebookSDK.h, use shared FBSession, native dialogs)

不同的头文件冲突并且看起来完全不兼容。

The different header files collide and seem completely incompatible.

可以我这两个都做？如果是这样，那么如何？

Can I do both? If so, then how?

推荐答案

只需包含Facebook.h即可。要首先执行此操作，请将DeprecatedHeaders文件夹复制到Frameworks项目中。 DeprecatedHeaders位于〜/ Documents / FacebookSDK / FacebookSDK.frameworks / Versions / A /下。复制时不要将项目复制到项目中，因此将它们复制为参考。

Just include Facebook.h instead. To do this first, Copy the DeprecatedHeaders folder into your Frameworks project. The DeprecatedHeaders are found under ~/Documents/FacebookSDK/FacebookSDK.frameworks/Versions/A/. When you copy it over do not copy the items into your project, so they stay copied as a reference.

接下来，在您的代码中：

Next, in your code where you have:

#import <FacebookSDK/FacebookSDK.h>

替换为：

#import "Facebook.h"

您可能会收到错误，哪个案例关闭并重新打开项目。

You may get an error, in which case close and reopen the project.

接下来，您希望声明一个Facebook对象并设置会话或在会话打开或关闭时清除它。

Next you want to declare a Facebook object and set the session or clear it whenever your Session is open or closed.

以示例为例： https://github.com/fbsamples/ios-3.1-howtos/tree/master/ShareNativeDialogsHowTo ， https://developers.facebook.com/docs/howtos/share-native-dialogs-ios-sdk/

您可以对该示例进行以下更改以回退到Feed对话框，而不是回退到具有共享UI的视图控制器。在ViewController.m中，您将在包含Facebook标题后进行这些更改：

You could make the following changes to that sample to fallback to the feed dialog instead of falling back to a view controller with a share UI. In ViewController.m you would make these changes after including the Facebook header:

....
@property (unsafe_unretained, nonatomic) IBOutlet UIButton *publishButton;
@property (nonatomic, retain) Facebook *facebook;

....
@synthesize authButton;
@synthesize facebook = _facebook;

....
- (void)sessionStateChanged:(NSNotification*)notification {
    if (FBSession.activeSession.isOpen) {
        self.publishButton.hidden = NO;
        [self.authButton setTitle:@"Logout" forState:UIControlStateNormal];
        if (nil == self.facebook) {
            self.facebook = [[Facebook alloc]
                             initWithAppId:FBSession.activeSession.appID
                             andDelegate:nil];
            // Store the Facebook session information
            self.facebook.accessToken = FBSession.activeSession.accessToken;
            self.facebook.expirationDate = FBSession.activeSession.expirationDate;
        }
    } else {
        self.publishButton.hidden = YES;
        [self.authButton setTitle:@"Login" forState:UIControlStateNormal];
        self.facebook = nil;
    }
}

- (void) publishUsingFeedDialog {
    // Put together the dialog parameters
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"Facebook SDK for iOS", @"name",
                                   @"Build great social apps and get more installs.", @"caption",
                                   @"The Facebook SDK for iOS makes it easier and faster to develop Facebook integrated iOS apps.", @"description",
                                   @"https://developers.facebook.com/ios", @"link",
                                   @"https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png", @"picture",
                                   nil];

    // Invoke the dialog
    [self.facebook dialog:@"feed" andParams:params andDelegate:nil];
}


- (IBAction)publishButtonAction:(id)sender {
    BOOL displayedNativeDialog =
    [FBNativeDialogs
     presentShareDialogModallyFrom:self
     initialText:@""
    ....

    if (!displayedNativeDialog) {
        /*ShareViewController *viewController =
        [[ShareViewController alloc] initWithNibName:@"ShareViewController"
                                              bundle:nil];
        [self presentViewController:viewController
                           animated:YES
                         completion:nil];*/
        [self publishUsingFeedDialog];
    }
}
