Open Facebook app with predefined text to share - ios

Question

Please take a look at this piece of code:
NSString *text = [NSString stringWithFormat:#"%#",
[#"Hello world!" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *post = [NSString stringWithFormat:#"fb://publish/profile/me?text=%#", text];
NSURL* url = [NSURL URLWithString:post];
if ([[UIApplication sharedApplication] canOpenURL:url])
{
[[UIApplication sharedApplication] openURL:url];
}
By means of this code I would like to open Facebook app installed on the device and open it on a share dialog with the text string used as a predefined text to share. But unfortunately what it does is just open my timeline. What am I doing wrong? Or is it even possible? I can't find any documentation or tutorial on how to do that properly. Thanks

There is simple way using FacebookSDK's framework. This takes only 2 minutes to go.
FBSDKCoreKit.framework
FBSDKShareKit.framework
If in your device facebook app is not installed then this will open default web browser.
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKShareKit/FBSDKShareKit.h>
// in viewdidload or somewhere else
FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
content.contentTitle = #"Scare Prank";
content.contentDescription = #"Someone just got Scare Pranked with ♫";
content.contentURL = [NSURL URLWithString:soundUrl];
content.imageURL = [NSURL URLWithString:#“some icon url”];
FBSDKShareButton *button = [[FBSDKShareButton alloc] initWithFrame:CGRectMake(0, 0, 200, 43)];
button.center = self.center;
button.shareContent = content;
[self addSubview:button];
