iOS build failure

[craig-at-rsg]

Issue: xcode fails to build AppPreferences.m

The message is:
.../Plugins/cordova-plugin-app-preferences/AppPreferences.m:24:16: No visible @interface for 'UIView' declares the selector 'stringByEvaluatingJavaScriptFromString:'

Here's the function:

- (void)defaultsChanged:(NSNotification *)notification {
	NSString * jsCallBack = [NSString stringWithFormat:@"cordova.fireDocumentEvent('preferencesChanged');"];
	[self.webView stringByEvaluatingJavaScriptFromString:jsCallBack];
}
