I have a older app where in a UIWebView I loaded a movie from a URL. It worked just fine. But now on iOS 5 ... when I enter the ViewController containing the UIWebView ... the thumbnail of the video starts "growing" like someone would zoom on it and it doesn't stop.
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.link_go_here"]];
[infoWebView loadRequest:request];
(it's a universal app ... the same happens on both devices)
Have you set the infoWebView.scalesPageToFit = NO; property of the webview? You could also try to set
<meta name='viewport' content='initial-scale=1.0,maximum-scale=1.0'/>
of the html page your 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 webview.. with the following attributes:
1.scalesPageToFit
2.Autoresizing masks
3.contentmode = aspectFit
After loading it fits to the page as obvious. But as soon as i zoom in and then zoom out to normal; rotating the device doesn't fit completely.
As a tweak, i have checked if the orientation mode is landscape reload the web page. I read various posts in this regard, but couldn't find any solution.
You have 2 folowing options:
Add this into head section of your html file:
<meta name="viewport" content="width=device-width" />
Or call [myWebView reload] when orientation changes
You can use this Code
NSString *website =#"http://www.google.com";
NSURL *url = [NSURL URLWithString:website];
NSURLRequest *requestURL =[NSURLRequest requestWithURL:url];
mywebview.scalesPageToFit = YES;
mywebview.autoresizesSubviews = YES;
[mywebview loadRequest:requestURL];
It took more than 2 days to find out the reason causing this issue. Actually webview was working correctly except the fact that if you try to use PinchGesture to zoom out further.. webview will baheve in the same way.
To overcome this issue, we need to set the zoom scale of scroll view in Webview under willRotate method. However, it's animating weirdly but one can make a guess where the issue lies.
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.
I have navigation controller with a tableview. When you click on one of the cells it pushes on a view with a uiwebview on it. You are taken to a YouTube page.
When you are on the table view in portrait and click on a cell you see the youtube page in portrait. Changing your orientation the video thumbnail does not refresh. So the thumbnail is smaller. This is fine. I actually prefer it smaller. All the content that would consume 2 lines will then consume 1 line. So in other words everything else adjusts for the new dimensions.
The problem comes in when you start off in landscape. Since the thumbnail doesn't resize on orientation change, changing to portrait mode, the image now goes off the screen, while the rest of the content adjusts correctly.
[webVIew refresh];
does work but it obviously loads the entire page again. So depending on the connection there will be a flicker or possibly the site will go white until its finished loading (on slower connections).
I also tried load the website in an iframe. I asked a similar question yesterday, this was for local pages i was creating. The answer to that question was to put <meta name='viewport' content='width=device-width; initial-scale=1.0; maximum-scale=1.0;'> in the head. So I tried that with an iframe going and getting the page. That seemed like a dumb hack to begin with, but i was willing to go there. It wouldn't even load the page at all. I guess because the youtube page i'm loading redirects to yet other page. Upon further research it seemed like there were other issues with the iframe such as scrolling.
So my question is how can i:
A. Get just the thumbnail to resize/reload on orientation change
OR
B. Get the thumbnail to load in the dimensions it would load in portrait mode all the time, even if it was started in landscape.
You should override this method in your UIViewController class and do the resizing there:
(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration;
I found the answer, maybe someone could explain it or offer a better solution. There was also an addition bug that I had to work out.
I made sure the uiwebview had the delegate set to files owner.
I changed the parent view when it pushed the view onto the form from:
[self.navigationController pushViewController:controller animated:YES];
to (the important part being the 320, i'm restricting the view to portrait):
[self.navigationController pushViewController:controller animated:YES];
controller.webView.hidden = YES;
controller.webView.frame=CGRectMake(0, 0, 320,367);
3.On the webview i load the url as i always did:
NSURL *url = [NSURL URLWithString:sUrl];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
4.In the webviewdidfinishload i now have:
if (self.interfaceOrientation ==
UIInterfaceOrientationLandscapeLeft ||
self.interfaceOrientation ==
UIInterfaceOrientationLandscapeRight) {
self.webView.frame=CGRectMake(0, 0, 480,227);
}
self.webView.hidden = NO;
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
All this would normally have solved my issue, but then i found out that the gdata url i'm getting from youtube service actually gets resolved to a 2nd url. Then i guess youtube changed their url format so it is forwarded to a 3rd url. This means that my didfinishload code was being called before the final url had loaded. To solve this i added:
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if ([[[NSString stringWithFormat:#"%#",request.URL] substringWithRange:NSMakeRange(0, 26)] isEqualToString:#"http://m.youtube.com/watch"]) {
NSString *sUrl=[NSString stringWithFormat:#"%#",request.URL];
sUrl = [sUrl stringByReplacingOccurrencesOfString:#"http://m.youtube.com/watch?" withString:#"http://m.youtube.com/#/watch?"];
NSURL *url = [NSURL URLWithString:sUrl];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
return NO;
}
//NSLog(#"request:%#",request.URL);
return YES;
}
Which im sure could be better but basically i tell it to ignore the 2nd url, and make my own change to go to the 3rd url.
Up until a few days ago it worked fine: opening facebook.com in iPad/UIWebView rendered as standard web. Now Facebook is force-rendered as touch - as if the URL was http://touch.facebook.com. This happens regardless of the UIWebView frame size. Here is a simple code for the main view controller to see the problem:
UIWebView *wv = [[UIWebView alloc] initWithFrame:self.view.frame];
NSURLRequest *req = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.facebook.com"]];
[wv loadRequest: req];
[self.view addSubview: wv];
I tried changing the user agent as suggested here - no good.
Using http://www.facebook.com?m2w should resolve this. "m2w" sounds like it is short for "mobile 2 web", and it's the link that you arrive at when you click "full site" from the mobile site.
