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;

In my app there is a vimeo video. I have opened it in WebView using following code ;
NSURL *url = [NSURL URLWithString:#"https://vimeo.com/47278503"];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
webview.delegate = self;
[webview loadRequest:req];
And place one cancel button above the WebView to close the vimeo video.
But the problem is that audio still plays after closing the WebView by clicking that cancel button.
And another issue is that on viewing full screen, video is not showing ,only audio plays in background and after clicking cancel button the video is playing in background.
UPDATE :
There is a similar issue in link. I have tried it's code but it doesnt work. I have written the code
[self.view addSubview:self.view.window.rootViewController.view];
in tableview's didSelectRowAtIndexPath() method. (and this tableview is in popover).
I have also tried [self.view addSubview:self.view.window.rootViewController.view]; in WebView's viewDidLoad() , but it doesnt work.
What can be the issue ?
Thanks.
for stop BG sound. you just remove, release and set nil to your UIWebView.
I have a UIView which, on viewDidLoad creates and shows a UIWebView. The web view doesn't actually show its contents until the view has actually appeared though. The navigation bar appears with the view during its animation process but the web view is populated a second after the animation has finished. How can I make the web view load the contents BEFORE animation begins. Here is my code, thanks:
-(void)viewDidLoad
{
[super viewDidLoad];
self.title = #"Help";
NSString *html = #"my html contents goes here, all local and all within a string - does contain one BG image though";
UIWebView *webView = [[UIWebView alloc] initWithFrame:_webFrame];
NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithpath:path];
[webView loadHTMLString:html baseURL:baseURL];
[self.view addSubView:webView];
[webView release];
}
I think a UIWebView needs some time to initialize, since it uses the WebKit engine.
You could try adding a simple timeout before actually pushing the new viewcontroller or show a placeholder during the 'push' animation.
As far as I know, a UIWebView has to be on screen in order to load and render.
i'd try the following:
create and add web view on the calling view controller.
set frame of the web view in a way only one pixel is shown on screen.
load html content.
push to new ViewController, remove Web View from old parent and add to new one.
might work, but it's really not worth the hassle, why not try to "solve" the issue by adding a load indicator or a placeholder text?
I am loading a UIWebview of a hosted .jpg. It's actually a schedule, so it is a rather large image. Instead of having users have to zoom in right away, I would like to load the web view already zoomed in. Although I still need the user to be able to zoom in and out, and scroll. Basically I am just looking for an "initial" zoom. How would I accomplish this? Just FYI I put the method below I am using to load the image...Thanks!
// Webview code
NSString *urlAddress = #"http://www.google.com";
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[webview loadRequest:requestObj];
In iOS 5 you can access the UIWebView's scrollView property and set the zoom level on it after the page has loaded. That would likely work as you wanted. To get the same thing on pre-iOS 5 you'd probably want to go through the UIWebView's subviews until you find a UIScrollView and do the same thing on that.
I don't think there's any other way to programatically zoom it. Unless you can do it with Javascript and execute some using UIWebView's stringByEvaluatingJavaScriptFromString: method.
If you have a UIWebView with a textfield and a button that takes the value from that textfield and then performs some action.
When you touch the textfield, the keyboard is displayed with a Go Button. I'm trying to figure out what exactly happens under the hood when that Go Button is pressed?
How I would simulate that action programmatically?
The following will be used, when user press on GO button of Keyboard ...
NSString *urlAddress = mytextFieldText.text;
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *aRequest = [NSURLRequest requestWithURL:aURL];
//load the index.html file into the web view.
[aWebView loadRequest:aRequest];
Thanks

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.
