i want to add a facebook like button in my app. in developer.facebook.com i couldn't fine anything about that. is it possible to use iframe created by facebook like button in UIWebView? it think if its possible then i can add a UIWebView in my app which use that iframe. thanx. please write some example code.
Yes it is possible, I am using iFrame to load youtube Video inside the app.
Following simple steps will guide you to achieve it.
Step 1 : Create a UIWebView in xib
Step 2 : Connect it to your ViewController's .h file. (I am referring it as _wevView in my project).
Step 3 : Create a method embedYouTube in your ViewController's .m file.
-(void)embedYouTube {
// Read create a NSString object with iframe
NSString *embedHTML = #"<iframe width=\"300\" height=\"250\" src=\"http://www.youtube.com/embed/rOPI5LDo7mg\" frameborder=\"0\" allowfullscreen></iframe>";
// Initialize the html data to webview
[_webView loadHTMLString:embedHTML baseURL:nil];
// Add webview to your main view
[self.view addSubview:_webView];
}
Step 4: Add the webview to your main view by by making a call to the method embedYouTube inside viewDidLoad
[self embedYouTube];
Step 5: Compile and run the app. You should be able to view the YouTube player embedded in the page.
Yes that is possible you can use the iframe in webview. You need to load the webview with the HTML string. You can also find the related code of HTML for iframe if you search over the net. Moreover you can also use javascript, in webview using the method stringByEvaluatingJavaScript: of UIWebview.

Here we are using UIWebview related application.
while clicking on some links, it's automatically connect(go) to the itunes.
but it's cannot get back to the app after clicking a itunes link (with out clicking on Exit).
My Question is, how can come back to the app after clicking a itunes.
Try this one uiwebview delegate method.
-(BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType
{
NSURL* url = [request URL];
if (UIWebViewNavigationTypeLinkClicked == navigationType)
{
[[UIApplication sharedApplication] openURL:url];
return NO;
}
return YES;
}
I usually insert a button next to UIWebView.
Use a new view and insert button in any corner of view and then put your UIWebView, set your uiwebview is not fit to screen so you can push to exit button. When you tap to button than hide your view. ITs usually what i do for such situation, maybe it can help to you
When you click on any link and you now go to at this link of page and if you want to go previous to your application. Generally You can not go Back to your Application because Apple iOS does not provide this types of feature.
I am not sure but It may be possible in JB Device.
you can add custom tool bar at the top of your view and add back button to custom tool bar to come back to your app. Below to custom tool bar add your webview.Hope it will helps you.
If you are loading the webpage with Safri or you are opening iTunes app with custom schema, it is not possible, because you are leaving the app.
But yes you can do this, If you will load that itunes connect link through web view, and there you can place a custom back button to come back to your previous page.
For Example :
UIWebView *webView=[[UIWebView alloc]init];
[self.view addSubview:webView];
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.xyz.com"]]];
This is very strange to me...
I have a simple WebView that loads and interacts with the user exactly like safari mobile (iPhone). Now when you visit m.youtube.com in safari, the url changes when you click on a link to something like this...
http://m.youtube.com/watch?gl=US&hl=en&client=mv-google&v=HX6SyoZ5kw8
The problem with this is I don't think that url is being used in my webview... What do I mean? The following code is used to load a url every time the user try's to click on a link, and it works, but I have a problem with Youtube...
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {
NSURL *url = request.URL;
NSString *urlString = url.absoluteString;
NSLog(#"%#",urlString);
VideoURLTextBox.text = urlString;
return YES;
}
When I first start up the webview it loads m.youtube.com and NSLogs() it into my console, but when I decide to click on a video it fails to NSLog() therefore I don't think a new url is being loaded, but when you load m.youtube.com in safari and click on a video you load a url like above, so why does this not NSLog() in my iPhone application?
What your probably seeing is that the youtube video is running javascript to play the video, you'd have to intercept the javascript callbacks to see that. Here's a link to the youtube video player api, detailing the callbacks, https://developers.google.com/youtube/js_api_reference#SubscribingEvents
If you just want to embed a youtube video in an iOS application then use this.
Using the mobile YouTube site isn't great, I had lots of problems with it in the past and ended up making a UIWebView category. I came across your question and decided to throw it on github :-)
https://github.com/enigmaticflare/UIWebView-YouTube--iOS-Category--ARC-compliant-code
UIWebView+YouTube iOS category to simplify loading youtube videos.
Instructions
1) Add these files to your project
UIWebView+YouTube.h
UIWebView+YouTube.m
2) Initiate UIWebView for example
#property (strong, nonatomic) UIWebView *webView;
#synthesize webView = _webView
_webView = [[UIWebView alloc] initWithFrame:CGRectMake(0,0,212,172];
//set the X,Y origin of CGRect to where you want the webView to appear.
_webView.delegate = self;
[_webView loadYouTubeVideoID:#"gR8dO7Cln6M"];
[self.view addSubView:_webView];
Good luck, hope this is what your looking for :)

m.youtube.com is one giant java web app, delegate methods won't get called, presumably because any loading is written directly to the DOM in the UIWebView. Ran into this problem at work, not sure of the fix but there may be a way to inject the source with a JS click handler.
For legal reasons, I'm obligated to show Terms of Service in my application, a PDF on an external server. What I believe would be easiest to do would be to create a UIBarButton item and then create an IBAction that launches the link in Safari.
So I create a button:
IBOutlet UIBarButtonItem *legal;
Then I make it into a nonatomic property and synthesize it in my implementation file, right? I go on to create an IBAction:
-(IBAction)legalButtonPressed:(id)sender;
I go into my implementation file, and here's where the issue comes. When it comes to defining those actions, I become confused. As I am new to iOS development, I could use some guidance. I don't know how to force the link into safari in the action. Any help would be greatly appreciated!
Thanks!
IBOutlet and IBActions are used for Interface Builder connections. If you have your UIBarButtonItem on a xib file, you can connect its action to the controller by right clicking in the files owner object. The same with the outlet.
Once you have the action in the controller connected to the button in the xib file, (I see no need to get an outlet here), you just implement the method as follows:
-(IBAction)legalButtonPressed:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString: #"http://yourdomain.com/legal.pdf"]];
}
this will automatically open safari with the given url
Take a look at UIApplication's documentation, it has a openURL method you might find useful.
Another option is to include your legal text in a UITextView.
Example:
By clicking Join you agree to company's
Terms of Service, found here: http://www.site.com/tos.html and
Privacy Policy, found here: http://www.site.com/privacy.html
Make sure Link Detection is turned on in the UITextView and it will automatically recognize URLs. Any clicks on those URLs will automatically launch Safari.
Although you can do this approach (i.e. launch the link in Safari). I would suggest that you try to keep the user as much as possible in your app. I am guessing this LEGAL TERMS is a HTML doc?
You can do that using UIWebView. Init a webView and do this -
NSURL *url = [NSURL URLWithString:webAddress];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[webView loadRequest:req];
This will open the url in your app only! You can make the UIWebView open up as a modal window or in many other ways...
I have never use youtube api in iPhone ...I tried to use GData but was missed in some steps here are link ans tutorial ....So never implemented it...
Due to which i used RSS feed and load it on tableView ...
and when user click on any row then the actual webPage opens in WebView and user have to click on the video to run it....
But now i don't want this ....
Can anyone provide me a better solution....
Thanks...
As I have given a brief answer here
I am explaining it in detail:
Put a button of same size and without any background image over your webview.
When the user presses this button open a new modal view with only a full screen size webview in it.
Pass the same html string to load the webview (that you were passing in your smaller webview).
Pass the touches programmatically to the webview like:
– (void) touchTheWebViewProgrammatically{
for(UIView* vw in [webView subviews]){
if([vw isKindOfClass:[UIButton Class]])
[vw sendActionsForControlEvents:UIControlEventAllEvents];
}
}
In my app i want to put my website's url on home screen and on clicking on it i want it to be open as a WebView.
How should i go for this.
Thanks,
Previous commenter is incorrect. You can open any hyperlink either externally with Safari or internally with a UIWebView.
Add a UIWebViewController to your project. Then, instantiate an instance of a the UIWebViewController that will be shown inside your app--you'll do this by declaring a property & synthesizing it within your main view controller (which will need to be declared as a UIWebViewDelegate), such as:
#interface MyMainViewController: UIViewController <UIWebViewDelegate> {
// Your implementation code here
}
When a user taps the button (assuming you make it a button, rather than just a text hyperlink), you instruct your app to add the UIWebView to the view stack, loading the correct link. You'll want to either do this within a modal view or within a navigation stack so your users can get back out of the web view, of course.
In your MyMainViewController implementation file, something like this:
-(void) showWebView {
// NOTE: I have not tested this, just prototyping
// off the top of my head
UIWebView *myWebView = [[UIWebView alloc] init];
myWebView.delegate = self;
NSURL *homeUrl = [[NSURL alloc] initWithString:#"http://example.com"];
NSURLRequest *homeRequest = [NSURLRequest requestWithURL:homeURL];
[myWebView loadRequest:homeRequest];
[self.presentModalViewController: myWebView animated:YES];
// Don't forget to release objects when you're done
[myWebView release]; // etc.
}
Now, this is off the top of my head from what I know and have done. But I hope you get the general idea. I offer no warranty of any kind here, but do guarantee this is entirely possible with minimal headache. If you get stuck, check out the developer references for UIWebView. Apple's docs are top-notch & show great examples to get you up and running quickly.
Best.
