Hello Everyone i am trying to play video based on URL that i am getting through API but i am getting Error like Access Denied.
The reason why i am playing video in UIWebView is because Video is not the Primary feature in my Application its just for Show Tutorial to the User so i have not used MPMoviePlayerController but if required than i can use.
But i want know the exact reason why such Error occurs in UIWebView.
Any guide or help will be appreciated.
Thanks in Advance.
Add below method to your ViewController.m :
//This method should get called when you want to add and load the webview
- (void)loadUIWebView
{
UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.bounds];
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:currentURL]]];
[self.view addSubview:webView];
[webView release]; // No need of this line if ARC is implemented in your project
}
Using Interface Builder-
Add a UIWebView object to your interface.
Set the "hidden" property to checked (in the "Attributes Inspector" window in Interface Builder). You should keep it hidden until you want to display WebView.
Add the following code to your ViewController.h.
#property (nonatomic, retain) IBOutlet UIWebView *webView;
Add the following line below the #synthesize in your ViewController.m
#synthesize webView;
Add [webView release]; in the dealloc method. // No need of this line if ARC is implemented in your project
}
Go back into IB and click on File's Owner, and connect the webView
outlet to the webView you created.
Add the following method.
//This method should get called when you want to add and load the webview
- (void)loadUIWebView
{
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:currentURL]]];
self.webView.hidden = NO;
}
I hope it will help you.

I am working on an IPhone app and i have a UIWebview that by default loads a url.
I need to create a UIToolbar with three buttons under UIWebview which will allow users to hit the buttons and load a new url in UIWebview?
you have to add three buttons to your toolbar( This can be easily done by using the Interface builder(IB) and connect them to there respective IBAction in the IB.
now when tap on a a button you can do like this.
you have a UIWebView say myWebView //declared in .h file and properly linked with the your View using IB.
when you are done with the basic initialization
for button1 press
-(IBAction)button1:(id)sender
{
NSURL *url = [NSURL URLWithString:#"http://www.google.com"];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[myWebView loadRequest:requestObj];
}
so by clicking on the button1 google webpage is loaded in your webView.
do the same for other button also.
:)
These methods and properties of UIWebview maybe help:
- (void)reload;
- (void)stopLoading;
- (void)goBack;
- (void)goForward;
#property(nonatomic,readonly,getter=canGoBack) BOOL canGoBack;
#property(nonatomic,readonly,getter=canGoForward) BOOL canGoForward;
#property(nonatomic,readonly,getter=isLoading) BOOL loading;
i'm going to write an app including an UIWebView. So first I wanted to try it out by just simply loading an URL.
Created the UIWebView in Interface Builder
Hooked up to the code
#property(nonatomic,retain) IBOutlet UIWebView *webView;
viewDidLoad:
- (void)viewDidLoad {
[super viewDidLoad];
if(!webView)
{
webView = [[UIWebView alloc]init];
}
webView.delegate = self;
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.google.com"]]]; }
also I implemented the didFailLoadWithError and webViewDidFinishLoad delegate methods.
webViewDidFinishLoad is called and indicating that HTML has been loaded.
Problem is: Even though webViewDidFinishLoad is called, the UIWebView doesn't display the website. It's only showing white color. The scroll bars right and at the bottom are shown when the UIWebView is touched and dragged but not content is visible. Nowhere found anything. Seems quite strange..
EDIT
This screenshot shows the connections of the xib:

If you hooked everything up in Interface Builder correctly, the following lines should not be needed:
if(!webView)
{
webView = [[UIWebView alloc]init];
}
webView.delegate = self;
Try removing them and see what happens. Also, put an NSLog(...) in the webView:didFailLoadWithError: callback and see if it is output.
I got it.. I used synthesize in the following way:
#synthesize webView = _webView;
So it was necessary to call the UIWebView in the following way:
[self.webView loadRequest:...];
New to this naming convention which is why i'm not used to necessity of self
Have you checked the File's Owner connect to the webView you declared?
Besides, webViewDidFinishLoad does not mean the HTML was loaded!
Whatever the content is loaded successful, this method will be called.
I have this kind of 4 paragraphs.
like this:
I stand here today humbled by the task before us, grateful for the trust you have bestowed, mindful of the sacrifices borne by our ancestors. I thank President Bush for his service to our nation, as well as the generosity and cooperation he has shown throughout this transition.
I want to use this paragraphs in different views using webview.
I mean I want to show such paragraphs in UIWebview
can anyone please tell me how to do this?
[webView1 loadHTMLString:#"Welcome to StackOverFlow" baseURL:nil];
[myWebView loadHTMLString:#"<p>I stand here today humbled by the task before us, grateful for the trust you have bestowed, mindful of the sacrifices borne by our ancestors. I thank President Bush for his service to our nation, as well as the generosity and cooperation he has shown throughout this transition</p>"]
If you really have to show the Text in an UIWebview implement a class which implements the UIWebView Delegate protocoll, like this:
#interface Web : UIViewController <UIWebViewDelegate> {
UIWebView *webView;
NSString *uRLString;
}
#property (nonatomic, retain) IBOutlet UIWebView *webView;
#property (nonatomic, retain) NSString *uRLString;
in your .m file you set the delegate and the view in your viewDidLoad like this:
self.view = webView.view;
self.webView.delegate = self;
and implement the openURL like this:
- (void)openURL:(NSString *)urlString
{
[myWebView loadHTMLString: <your static string in html-formate>]
}
But like I said before: You should use an UITextView to stick to Apple guidelines and you can also set preferences of UITextView without IB. In fact you really never HAVE to use the IB.
For a current project I am embedding a mobile site into an iOS app. I've taken use of the goback() and goforward() functions, with UIWebView. But how would I make a custom function that onClick (or onTouch which ever is the correct term) Sends the UIWebView back to the page initially loaded? Any Help would be much appreciated as I have bene unable to find anything on the web thus far.
Add something like to the implementation file:
- (IBAction)loadPage:(id)sender;
{
NSURL *url = [NSURL URLWithString:#"http://www.stackoverflow.com/"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];
}
And add this to the header file (each line at the appropriate position):
- (IBAction)loadPage:(id)sender;
IBOutlet UIWebView *webView;
Then bind the button to loadPage within interface builder,
and bind webView to the UIWebView.
Response to comment:
I created this sample project, hopefully it helps:
- http://dd5.org/static/iPhone_Browser_Sample.zip
Binding the button:
Right-click and drag to the class where you added the code above.
Release the button. Now a little dark-gray panel should appear.
Then click on the loadPage: entry within that panel.
If the code was added correctly, the entry should show up there.
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.
