How do you prevent a WebView from cropping the web content? - ios

I thought the content would wrap to fit inside the WebView, but instead the right hand side is clipped off.
Sorry for asking such a noob question (WV should just wrap!).

Wrapping would be done in the HTML5 webpage, as it understands the device(PC or Mobile) and behaves accordingly, for others you need special webpage e.g. (m.facebook.com which acts as interface for mobile and www.facebook.com for PCs).
For displaying the complete screen in single screen webview(scaled down) use the following code
yourWebView.scalesPageToFit = YES;

Iframe automatically goes full screen using Ionic 3.9.2 on iOS

Iframe automatically goes full screen using Ionic 3.9.2 on iOS.
I've tried removing all the fullscreen tags. I notice that it is not happening anywhere else. Only happens on iOS. On other devices, I have to manually make it full screen.
Why does Iframe automatically go full screen on iOS?
<iframe src="https://d1mlukbqb3dh9w.cloudfront.net/PortraitCourse/Module01/Module01Section1/story.html" height="655" width="100%"></iframe>
A while ago I would have been able to provide you with a spot-on answer. Unfortunately I no longer have access to the resources I would need to do so... meaning my answer won't be a complete solution.
IFRAME, on iOS, works slightly differently than on Android. Getting an IFRAME to take only the height you want is not simply a matter of setting the HEIGHT property on the tag as the rendering engine works differently. You'll have to play around with CSS both in the container of the tag and in the contents of the body itself.
Try proceeding as follows:
prepare a mock target page that doesn't take all the height, make
its background red and see how much space it takes
make the mock page longer than the height of the screen by adding lots of text and images to it and observe the change
wrap the IFRAME in a DIV and set the style=height: xxx of the div, as well as its overflow.
wrap the contents of the mock page in a div, setting its height, overflow, position and display style
properties to control its appearance.
repeat step (4) with both the HTML and BODY tags of the mock page.
Playing with these in real-time using Safari to alter their values will prove most useful. It was to me at least, when I had the problem over an year ago.

Adjust WinRT WebView content to control

im trying to fit a Facebook likebox in a webview on a Windows Store APP.
I have done it fine on Android and IOS, just setting the likebox url as html string to the webview.
But in WinRT it shows the box on the upper left corner and A LOT of white space, so the box is really small, i can zoom in to fit it well by hand.
Android and IOS just fit the box in the webview.
Is there any way i can fit it well? also i need to disable user scroll, i only want the user to be able to click the like button.
Thanks in advance.

html5/css3, Asp.net MVC3 - View pdf in an html page on mobile safari

My upcoming mobile web project requires viewing dynamically chosen pdf files inside the webpage. I am using iFrame to display the pdf file and the file can be scrolled using two-finger scrolling. But the problems I am facing are:
The first page of the file is not displayed completely on the iPad and gets cut off along the width unlike when I view it on the desktop browsers where the first page of the pdf is always entirely displayed although zoomed out to fit in the iFrame area.
There is no visual indication for the users that the pdf document can be scrolled, i.e., there is no scroll bar on the pdf document.
The controls (page navigation, zoom etc.) for the pdf viewer (Adobe reader) don't appear on the document unlike when I see it on the desktop browsers.
What is the best way to achieve what I am trying to do? Do any of you experts know any solutions/workarounds to the problems I am facing? An entirely different approach using anything other than iFrame can also be considered.
The reason why the pdf should be inside the html page is that, the list of pdf files will be on a menu bar on the left side of the page and the user can click on any of them to view on the same page. Ideally, they will have the capability to toggle between full screen view and that view.
Any help is appreciated.
I created a tiny JavaScript module that helps you to show a PDF inline and be able to scroll it. But I also couldn't figure out a way to make it fit the total width of the parent container.

I came across this Recommended way to embed PDF in HTML? while researching on the web to find an answer.
The mentioned link discusses about some options that I can use and the google document viewer works for me though don't know if there is anything (like data limit) I need to be aware of before using it on the website. Also I have no idea if it is a good solution (though the full screen mode is not available, but zoom-in/zoom-out and next/prev page buttons are there are show up in the mobile safari on the iPad) to use for an web app that will be run on the iPad.
Anyway, I will keep researching for a better solution and if i don't find any, I'll stick to the google document viewer.
The issue appears to be a bug with Safari on the IPad.
I didn't find a solution for embedding the pdf in html but I did find this:
If you return FileStreamResult from your controller action instead of a view, the pdf will open in a new tab, it's not embedded html but at least your user is not having to download files and open them manually.
I had the same problem of the pdf not being displayed completely. The only thing I found to fix this was the change the size of the div containing the pdf.
For example if the element containing the pdf is a div then I change its width to any value and the rollback to the value it had before. Changing Width or height any one works.
Sometimes I had to wait a little using a setTimeout before calling my resizable method

Like Box Social Plugin iframe doesn't scroll in an UIWebView

I loaded the Like Box iframe code generated on Facebook into an UIWebView on my iPhone App. It works well, but when I scroll, it scrolls the UIWebView itself, and not the content inside the iframe. How can I block the UIWebView from scrolling (i.e the UIWebView takes the fullscreen frame) and allow the overflowed content of the iframe to scroll instead ?
ps : I tested a simple .html in MobileSafari.app and I have the same problem
You use two fingers in the like box instead of one. Then it scrolls.
You won't have much control over a plugin that is rendered as an iframe due to cross domain restrictions and they do not give many options to customize the appearance.
You could replace it with a Facebook like button. Then below it, you could add code that reads and displays the Fan Page feed using the graph api's page's feed connection (/pageId/feed). This would give you full control over the rendering and still gives the user the option to like your page. To improve performance of this solution you could use the Facebook real-time updates API to get notified when new updates get posted to the page and then you could pull those down and cache them.

Scrolling on iPad for an iframe within GWT window

PLEASE NOTE: This is not a "use two fingers to scroll" problem. Whether it is one finger, or two, or three, or the whole hand, for some reason our iframe does not scroll on an iPad. :)
Here is the scenario:
In our web application, which is built using EXT-GWT, we have a few windows that open as (maximized) pop-ups and present some forms to the users. These forms, which are most of the times external, are rendered in an iFrame and some of the forms have their content collapsed at the initial load - the user can choose to expand any section of the form, fill it in and submit. Now everything works fine except the scrolling in iPad. After the iframe's content is loaded and collapsed (collapsing is done using JS on the client side, basically, the content loads as expanded by default and then is collapsed by JS) iPad just fails to provide scolling to the iframe. Even after the content of the iframe is expanded the iframe does not get any scrolling.
As of now, we have solved this problem by increasing the height (using JavaScript) of the EXT-GWT window to the size of the expanded iframe body content. This makes the whole window scrollable, instead of just the iframe within the window. While it works, the window becomes way to big, so I was wondering if there is any better way for us to provide scrolling to the iframe.
Thanks for the help,
Nitin
For iOS devices you need set overflow: auto; or the scrolling won't work. For my web apps I used fancybox to display iframes modally and once I change the overflow setting in the css file the two finger scroll worked perfectly on the iPad.
After trying (almost) everything, I have come to the conclusion that increasing the GWT window height to the iframe.body.height is the only solution for getting the window/iframe to scroll on iPad. Hopefully, this will help someone in future.
I´m pretty new to GWT, but for me it worked like this:
The parent-div of the iframe has a class in my case, x-component.
I made an entry to my css file like this:
.x-component{-webkit-overflow-scrolling: touch; overflow:auto;}
It works as well if I set these entries not to the class, but to the div-element itself.
Hope that helps
