Problem
We have an Ionic2 project. Ionic (on iOS) creates a Safari browser. Safari allows for what I call "overscroll". This is when you can scroll beyond the top or bottom of the page and the page snaps back.
One of our pages has a small signature pad. If a user tries to sign with their finger, they instead scroll the screen. The page content is small enough that it shouldn't be scrollable, but the overscroll causes the page to move.
Desired
We just want to disable the blasted overscroll.
Really all of our Ionic projects suffer from this drawback in some form or another, but this is the first project where it blatantly breaks functionality. In other cases it's just an annoyance.
Appeal
Is anyone familiar with how to disable this overscroll? Whether through ionic, a cordova plugin, or the HTML itself.
If I have understood you correctly then this is actually really easy to do.
Just add no-bounce to your <ion-content> element.
e.g.
<ion-content no-bounce>

I am currently developing a hybrid app in iOS that loads a website and has some other features (contacts, sharing, notifications...) using cordova plugins. I do have access to the content of the site that is being displayed by the iframe.
The normal way this is done is to load the website in an iframe. I have already done this in android and it works very well. In iOS however:
Safari messes up the size of the frame. I fixed this by setting the min-width css style to 100% for the frame.
Scrolling on the iframe is always set to "no" even if you specify "yes. I "fixed" this (so I thought) by using the only solution I could find which is to wrap the iframe in a div and scroll the div. This made the header (position:fixed) scroll with the page when it should be fixed to the top of the page and broke other things on the page that rely on scroll position to trigger an action. I also tried modifying the body of the content to contain css styles mentioned here but this didn't work either. I was back to square one.
I have spent a total of a week researching how to fix this with no avail. Recently I have discovered that loading my website in iOS's UIWebView or WKWebView works well to display the site exactly how I would expect.
That brings me to two possible solutions (and my question):
Maybe I missed something with the css style on the content of the site. I read that it is possible to get scrolling to work this way but I am sceptical because safari does not allow scrolling on an iframe.
(The likely solution but the one I cannot figure out) Make my cordova app use a one of iOS's webviews. This is what I am having problems with. I cannot figure out how to do this. Is a webview an iframe? How do I use one of these webviews in my app? What does the index.html (cordova specific file) look like when I use a webview instead of an iframe (because currently this is where my iframe is).
I solved this. Since I have access to the contents of the page, I added:
position:absolute
top: 0
right:0
bottom:0
left: 0
overflow-y: auto
overflow-x: hidden
-webkit-overflow-scrolling: touch
To the scrolling body of the page. This fixed my problem
I don't know if this is something that can be helped, but when I tap and hold on a web page in mobile safari, or in cordova/phonegap-made apps run in iOS, there is this pretty useless empty "tooltip" popping up close to the top of the viewport, and it only moves horizontally across the screen.
Here is a screenshot of what I'm talking about (that annoying thing circled in red that totally gives away that this is a cordova app)
My question being : is it possible to prevent this behavior, and how ? It seems to not be present on anchor <a> anchor elements but putting anchors all over the place seems like overkill for this.
And if anyone knows, just so I go to bed a little less stupid, what is this feature called and what is it for exactly ?
I already have the following css properties in my body
-webkit-user-select: none;
and
-webkit-touch-callout: none;
to prevent the text selection and the copy and save of images.
I've downloaded other phonegap-made apps from the App Store and they too have this feature, so maybe there's no fixing it.
Anyways, thanks for taking the time to read this.
It's a bug on the UIWebview
It's been fixed on cordova and will be available on next release, but you can use this plugin meanwhile

I am New to Phonegap Development, I am Using jQuery mobile to create my UI. I have two Issues here,
Response of button for touch event is very slow. Why..?
I have Created a form with some elements like 2 Inputs text type, 2 Button one after another.
M problem is when I click on input, the keyboard popup makes the page move up, that's OK but when I press the keyboard resign button, the page stay little up.
Can you please help me out..!
and how to Optimize the responsiveness of JQuery mobile UI. I have completely avoided the images.
First, you can follow this link to remove the delay (300ms) from the click event.
And for the second one, i hope you are facing this issue for android. if so, then you need some changes to be done on the AndroidManifest.xml
Use below android property in application tag,
android:hardwareAccelerated="false"
android:windowSoftInputMode="adjustPan"
Will look something like
<application android:icon="#drawable/icon" android:label="#string/app_name"
android:hardwareAccelerated="false"
android:windowSoftInputMode="adjustPan">
This should resolve your issue.
I am building a cross-platform app using jQueryMobile and Phonegap. Currently using jQM 1.1.0 and Phonegap 1.6.1.
The page transition function sometimes just seems to break down when the user clicks a button or list item that links to another page in the app.
<a href="#page2">
This kind of link is what the whole app is made of. But depending on god knows what, sometimes when you click a link the app stalls. External links will still be followed, and buttons that don't trigger any page changing work fine. But anything with href and $.mobile.changePage seems to be broken.
This problem occurs in iPad Simulator and iPhone Simulator, not in Chrome. It seems to have something to do with the type of page transition specified (i.e. fade or slide or flip etc). Some transitions seem to cause problems, sometimes it seems to be the lack of a specified transition that is the cause, and sometimes neither of those explanations have any traction.
Before I add a whole bunch of code, I'm interested if anyone has similar experiences.
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,

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
