使用ShareSDK完成Facebook第三方登录和Facebook分享时没办法跳转到Facebook应用

NSMutableDictionary *shareParams =[NSMutableDictionary dictionary];

So with iOS 9 out, there are a few enhancements in security. With that being said, the way your app integrates Facebook may be acting strange, or not working at all.

More than likely this is because you are being affected by App Transport Security. ‘App Transport Security is a feature that improves the security of connections between an app and web services. The feature consists of default connection requirements that conform to best practices for secure connections. Apps can override this default behavior and turn off transport security. ‘ -Apple

With all this being said, this is definitely something that you want to keep inside of your app. But now…. how do you make it work!?!

There are two solutions

1.

First: Whitelist Facebook Servers for Network Requests.
To do this add the following to your info.plist file:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>facebook.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>                
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
        <key>fbcdn.net</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
        <key>akamaihd.net</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
    </dict>
</dict>

Then, Whitelist Facebook Apps by adding this to your info.plist as well:

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fbapi20130214</string>
    <string>fbapi20130410</string>
    <string>fbapi20130702</string>
    <string>fbapi20131010</string>
    <string>fbapi20131219</string>    
    <string>fbapi20140410</string>
    <string>fbapi20140116</string>
    <string>fbapi20150313</string>
    <string>fbapi20150629</string>
    <string>fbauth</string>
    <string>fbauth2</string>
    <string>fb-messenger-api20140430</string>
</array>

There you go, that should do the trick

2.

If this seems to be too much of a hassle for you, the second option is to turn off App Transport Security. You can do that by adding the following to your info.plist file:

<key>NSAppTransportSecurity</key>
<dict>
	<key>NSAllowsArbitraryLoads</key>
	<true/>
</dict>
