Adding the Facebook Like Button in an iPhone App
Solution 1
Check out this nice bit of code: http://angelolloqui.blogspot.com/2010/11/facebook-like-button-on-ios.html
Add the FBLikeButton
class to your view:
FBLikeButton *likeButton = [[FBLikeButton alloc] initWithFrame:CGRectMake(0, 372, 320, 44)
andUrl:@"http://www.facebook.com/pages/De-Zilk/108209735867960"];
Thanks a lot Angel García Olloqui
EDIT: Nice to add... For bonus points:
If you use above method the webpage is not well formatted for an iPhone. What you can do is run some JavaScript code to remove all the disturbing divs. Use this (long sentence):
[_webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"javascript:document.getElementsByClassName('uiButton')[2].style.visibility='hidden';var child1 = document.getElementById('standard_status');var parent1 = document.getElementById('login_form');parent1.removeChild(child1);var child2 = document.getElementById('pageheader');var parent2 = document.getElementById('booklet');parent2.removeChild(child2);document.getElementById('loginform').style.width = '200px';var child3 = document.getElementById('reg_btn_link');var parent3 = document.getElementsByClassName('register_link')[0];parent3.removeChild(child3);var child4 = document.getElementById('signup_area');var parent4 = document.getElementById('login_form');parent4.removeChild(child4);var child5 = document.getElementsByClassName('mbm')[0];var parent5 = document.getElementById('loginform');parent5.removeChild(child5);var child6 = document.getElementsByClassName('reset_password form_row')[0];var parent6 = document.getElementById('loginform');parent6.removeChild(child6);var child7 = document.getElementsByClassName('persistent')[0];var parent7 = document.getElementById('loginform');parent7.removeChild(child7);"]];
You can place it in the delegate method webViewDidFinishLoad
from the FBDialog
Facebook class.

It is an old question, but we just got the answer
By using fb sdk now we can simply add the like button
FBLikeControl *likeButton = [[FBLikeControl alloc] init];
like.objectID = @"http://ihackthati.wordpress.com/photo1/";
[self addSubview:like];

Fb like Widget can be embedded in our application. You just have to add a webView and get the Fb Like Widget html code/URL here.
in ViewController.h where you want to add fb like button:
#import <UIKit/UIKit.h>
@interface TestViewController : UIViewController <UIWebViewDelegate>
@property (strong, nonatomic) UIWebView * fbLikeWebView;
-(void)embedFBLikeButton;
@end
in TestViewController.m
#import "AboutUsViewController.h"
@implementation AboutUsViewController
@synthesize fbLikeWebView = _fbLikeWebView;
- (void)viewDidLoad
{
[super viewDidLoad];
//Add this code for FbLike Webview
self.fbLikeWebView = [[UIWebView alloc] initWithFrame: CGRectMake(100.0, 50.0, 55.0, 70.0)];
_fbLikeWebView.opaque = NO;
_fbLikeWebView.backgroundColor = [UIColor clearColor];
_fbLikeWebView.delegate = self;
[self.view addSubview:_fbLikeWebView];
for (UIScrollView *subview in _fbLikeWebView.subviews)
{
if ([subview isKindOfClass:[UIScrollView class]]) {
subview.scrollEnabled = NO;
subview.bounces = NO;
}
}
}
then in ViewWillAppear method call the enbeddFBLikeButton Method to add the fbLike button wigdet on web view:
-(void)viewWillAppear:(BOOL)animated
{
[self embedFBLikeButton];
[_fbLikeWebView reload];
}
-(void)embedFBLikeButton
{
NSString *facebookUrl = //here paste the url you get from fb developer link above;
[self.fbLikeWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:facebookUrl]]];
}
You conform to UIWebViewDelegate now its turn to defining th edelegate method here:
#pragma mark - WebView Delgate Methods
- (BOOL)webView:(UIWebView *)webview shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
if ([request.URL.lastPathComponent isEqualToString:@"login.php"])
{
[self login];
return NO;
}
return YES;
}
-(void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
[_fbLikeWebView stopLoading];
}
This method for login the user to facebook Account:
- (void)login
{
[FBSession setActiveSession: [[FBSession alloc] initWithPermissions:@[@"publish_actions", @"publish_stream", @"user_photos"]]];
[[FBSession activeSession] openWithBehavior: FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
switch (status) {
case FBSessionStateOpen:
// call the legacy session delegate
//Now the session is open do corresponding UI changes
if (session.isOpen) {
FBRequest *me = [FBRequest requestForMe];
[me startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *my,
NSError *error) {
if (!my) {
NSLog(@"Facebook error:\n%@", error.description);
[[[UIAlertView alloc] initWithTitle: @"Error"
message: @"Facebook Login error."
delegate: self
cancelButtonTitle: @"Ok"
otherButtonTitles: nil, nil] show];
return;
}
}];
[_fbLikeWebView reload];
[[[UIAlertView alloc] initWithTitle: @""
message: @"Successfully Login. Please click on like button"
delegate: self
cancelButtonTitle: @"Ok"
otherButtonTitles: nil, nil] show];
}
break;
case FBSessionStateClosedLoginFailed:
{
[_fbLikeWebView reload];
}
break;
default:
break; // so we do nothing in response to those state transitions
}
}];
}

Several of the solutions above (e.g. @floorjiann, @fabiobeta, @Stephen-Darlington, @scott) assume that the iPhone application is also a Facebook application (with its own id).
However if your iPhone application just has a fan page, this is not the case.

Hemang about 11 yearsIn the reply from the author, after this post Facebook has made 50 times changes to the SDK, so its now outdated and not like to avail.

Jayprakash Dubey over 8 yearsReplaced with FBSDKLikeButton in latest version of FB SDK. Also there is no selector initWithFrame.
