Build failed for iOS with SocialSharing-PhoneGap-Plugin

[AdamDiament]

I recently upgraded to Cordova 4.1.0 from 3.9.2 for iOS. iOS platform:Xcode 7.3.1, Build version 7D1014

I now get two errors when building for ios from the command line:

Error 1.

Plugins/cordova-plugin-socialsharing/SocialSharing.m:26:24: error:
no visible @interface for 'UIView' declares the selector
'stringByEvaluatingJavaScriptFromString:'

Error 2.
Plugins/cordova-plugin-socialsharing/SocialSharing.m:471:34: error:
no known class method for selector 'dataFromBase64String:'
NSData *fileData = [NSData dataFromBase64String:base64content];

for reference, seems like a similar issue to the one you fixed here Telerik-Verified-Plugins/PushNotification#71 with your push plugin earlier this year.

There are also 2 warnings:

1. /Plugins/cordova-plugin-socialsharing/SocialSharing.m:20:8: warning:
   incompatible pointer to integer conversion initializing 'BOOL'
   (aka 'signed char') with an expression of type 'Class _Nullable'
   [-Wint-conversion]
   BOOL avail = NSClassFromString(@"UIActivityViewController");
2. /Plugins/cordova-plugin-socialsharing/SocialSharing.m:76:15: warning:
   'setCompletionHandler:' is deprecated: first deprecated in iOS 8.0 - Use
   completionWithItemsHandler instead. [-Wdeprecated-declarations]

Really appreciate your plugins, and your help with this, thanks!

Which version of the plugin is this? Surely not the most recent one as line 26 (error 1) is not the same. Please update and try again.
