Mysterious magnifying glass in Facebook Feed Dialog - ios

Question

I installed Facebook iOS SDK via CocoaPods with Podfile
platform :ios, '6.0'
pod 'Facebook-iOS-SDK'
Screenshot is as follow:
A magnifying glass appears on the top right corner in Simulator, when I use the following code (in a button's IBAction) to attempt to share a message to Facebook (I follow the tutorial at Getting Started):
FBShareDialogParams *params = [[FBShareDialogParams alloc] init];
params.link = [NSURL URLWithString:#"http://www.google.com"];
params.name = #"Google";
params.caption = #"Google is Great";
params.picture = [NSURL URLWithString:#"http://i.imgur.com/g3Qc1HN.png"];
params.description = #"Google is a good search engine";
if([FBDialogs canPresentShareDialogWithParams:params]) {
// Present share dialog (requires Facebook App v6.0+ installed)
[FBDialogs presentShareDialogWithLink:params.link
name:params.name
caption:params.caption
description:params.description
picture:params.picture
clientState:nil
handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
if(error) {
NSLog(#"%#", [NSString stringWithFormat:#"Error publishing story: %#", error.description]);
} else {
NSLog(#"result %#", results);
}
}];
} else {
// Present feed dialog
NSMutableDictionary *params1 = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"Google", #"name",
#"Google is Great", #"caption",
#"Google is a good search engine", #"description",
#"http://www.google.com", #"link",
#"http://i.imgur.com/g3Qc1HN.png", #"picture",
nil];
[FBWebDialogs presentFeedDialogModallyWithSession:nil
parameters:params1
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
if (error) {
// An error occurred, we need to handle the error
// See: https://developers.facebook.com/docs/ios/errors
NSLog(#"%#",[NSString stringWithFormat:#"Error publishing story: %#", error.description]);
} else {
if (result == FBWebDialogResultDialogNotCompleted) {
// User cancelled.
NSLog(#"User cancelled.");
} else {
// Handle the publish feed callback
NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
if (![urlParams valueForKey:#"post_id"]) {
// User cancelled.
NSLog(#"User cancelled.");
} else {
// User clicked the Share button
NSString *result = [NSString stringWithFormat: #"Posted story, id: %#", [urlParams valueForKey:#"post_id"]];
NSLog(#"result %#", result);
}
}
}
}];
}
And this at the end of the class, before #end:
// A function for parsing URL parameters returned by the Feed Dialog.
- (NSDictionary*)parseURLParams:(NSString *)query {
NSArray *pairs = [query componentsSeparatedByString:#"&"];
NSMutableDictionary *params = [[NSMutableDictionary alloc] init];
for (NSString *pair in pairs) {
NSArray *kv = [pair componentsSeparatedByString:#"="];
NSString *val =
[kv[1] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
params[kv[0]] = val;
}
return params;
}
Feed dialog is used because the Simulator does not have Facebook App v6.0+
The magnifying glass blocks the Share button completely. How can I remove it?
Note: The version installed is v3.13.0 (at the moment of writing, the official latest version is 3.13.1).
Note: iOS used are 6.0, 7.0, 7.1.

This issue has been resolved by Facebook in server side. The magnifier has been removed.
No need to update Facebook SDK.
