I'm building a reactjs widget which has scrollable lists (vertically) inside it, which takes the entire viewport on mobile (I prevent the default for "touchmove" on the window so as not to scroll the background).
But when I open the widget on iPhone (tested on both Safari and Chrome), I can scroll down the list, but can't scroll back up! if I want to scroll back up, I need to scroll a bit down before I scroll up (one action, without lifting the finger).
I also have reversed lists (same design, only with flex-direction: column-reverse), and I have the exact same behavior regardless of the flex direction.
I also noticed that the "touchmove" event on the list is not firing when I can scroll, but it is firing when I can't.
It works great on desktop, tablets (iPad as well) and android devices - just not on iPhone.
I need the scroll to work both ways on iPhone as well
It was my mistake - it was a combination of using body-scroll-lock and preventDefault of "touchmove" on the body.
All fixed now
I need to scroll a list of images horizontally in ionic v3. I tried using ion-scroll component and works perfect for android platform, but i need same behavior in the browser.
So when I hide the scroll bar it doesn't work, also I tried to set scroll width to 0. Seems that the swipe funcionality only works in mobile devices.
::-webkit-scrollbar, *::-webkit-scrollbar {
display: none;
//width: 0 !important
}
I need to archive something like this.
I also check ngx-swiper-wrapper library, but i could not get the expected result.
Is there other library that can help with this?
Thanks.
I was trying to achieve the same (horizontal scrolling behavior across all devices and browser) and eventually did this using slider:
https://ionicframework.com/docs/components/#slides
Slides component is based on iDangerous swiper and was made to support coverflow like UIs with multiple slides visible: http://idangero.us/swiper/demos/110-slides-per-view.html
Here is simple implementation:

Am stumped! Have just found a very weird anomaly when viewing with an iPad. My forms work fine on a desktop computer and on the iPad in landscape mode but when in portrait mode the fields and buttons cannot be selected.
This form will not work in portrait mode:

But this one will:

Have no idea what might be causing this!!
Any help sorting this out most appreciated.

Try adding clear:both to #services-widget, it makes the element drop below floated elements.
I'm currently migrating my app on ios 7 and I've been stuck for hours on the new navigationcontroller/bar management.
Before, when we had a navigation controller, we had a snippet like this :
UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:[[MainViewController alloc]init]];
In interface builder, we had the choice to set an existing navigationbar for the view and everything match the content of the real view.
OK so now, i have no clue of how to design properly with interface builder.
I still have my snippet to initialize my navcontroller. However in the interface builder for my MainViewController if I set a status bar to translucent or opaque navigation bar, i have an offset of 44px at the top (see below).
Interface Builder_________________________And the result
Now, if i set status bar to none, there is no offset at top but since the view on simulator is smaller because of navigation bar the bottom of the view in interface builder is cut off.
Interface Builder_________________________And the result
I guess i'm really missing something here but i can't find any topic or apple info in iOS7 Transitions Guide about that.
Thanks for your help
EDIT
As we can see in the pictures, the first child of the view is a UIScrollView which contains both labels, the problem does not appear when there is no scrollview. It also appears if it's a UITableView.
If a label is outside the UIScrollView, there is no offset to that label.
OK so i found the solution, I have set in my controller the property:
self.automaticallyAdjustsScrollViewInsets = false
I don't really understand the true benefit of this property though, (or why the default value is true)
The only documentation i found was there:
https://web.archive.org/web/20160405135605/https://developer.apple.com/library/ios/documentation/userexperience/conceptual/TransitionGuide/AppearanceCustomization.html
https://developer.apple.com/documentation/uikit/uiviewcontroller/1621372-automaticallyadjustsscrollviewin
Update
In iOS 11 automaticallyAdjustsScrollViewInsets is deprecated
You should now use:
self.tableView.contentInsetAdjustmentBehavior = .never
I also encourage you to check this question and its answer to get a better understanding of those properties
#Justafinger's answer worked like a charm for me as well.
Just wanted to add that this setting can also be adjusted easily from the interface builder.
Select your view controller
Click the 'Attributes Inspector' tab
Uncheck 'Adjust Scroll View Insets'
Enjoy!
I was running into this same issue, but I found a rather odd property on the ViewController in interface builder that seems to have been causing this for me. There is an "Extend Edges" set of check boxes. I removed the "Under Top Bars" check, and everything started laying out properly for me.
With automaticallyAdjustsScrollViewInsets set to YES (the default setting) there is a mismatch in scrollview positioning between ios6 and ios7, so to make them consistent you need to disable this setting. However, ios6 will crash if it comes across automaticallyAdjustsScrollViewInsets, so you either need to make a programatic change of automaticallyAdjustsScrollViewInsets conditional on ios7 or else switch off the option using the storyboard/NIB
I had a similar problem, after dismissing a viewController, the contentOffset from my tableView was changed to (0, -64).
my solution was a little weird, I tried all the other answers but had no success, the only thing that fixed my problem was to switch the tableView position in the controls tree of the .xib
it was the first control in the parent View like this:
I moved the tableView right after the ImageView and it worked:
it seems that putting the table view in the first position was causing the trouble, and moving the table view to another position fixed the problem.
P.D. I'm not using autoLayout neither storyboards
hope this can help someone!
I also face this problem.
UIScrollView content size is calculate by OS as other sizes, origins provided by constraint system - that's why OS has doubtfulness.
How to fix - You should explicitly define content size of UIScrollView:
Embed scrollable content to UIView (I rename it to ContentView)
Add constraints:
ContentView.Weight = View.Weight and ContentView.Height = View.Height
It seems like a work around solution is to view the storyboard file as "iOS 6.1 and earlier" (select storyboard file->File inspector->Interface Builder Document->View As. Positioning subviews in this mode shows the offset.
Thank you guys for the solutions! I struggled for hours trying to solve the problem. Everything was ok when there was no Navigation Bar involved but it went haywire the moment I embedded the ViewController in a NavigationController.
I solved it by unchecking the Adjust Scroll View Insets and the Under Top Bars. Both of these are located in the ViewController's Attribute Inspector. Thanks a million!
Accepted answer by #streem caused some weird behavior with UILabel acting as sections.
This worked for me:
if let navBar = navigationController?.navigationBar {
scrollView.contentInset = UIEdgeInsets(top: -navBar.frame.size.height, left: 0.0, bottom: 0.0, right: 0.0)
}
In an ecommerce site, I would like to display number of items in a row according to browser width, but minimum will be 4 items. Just like what has been done in Amozon site, if you try to browse amozon.com, try to maximize and shrink your browser, you will find that number of items display in [More Items to Consider] section is according to your browser size. It is smart enough to know when it should fully hide or show an item, no partially visible item forever.
Anyone know what is this technology called? Any idea how this can be done? Thanks in advance.
You can do this with float elements in a div with overflow:hidden. I'll jsfiddle a proof of concept for you.
JSFiddle:
http://jsfiddle.net/WLEzw/
Make your browser window bigger and smaller and you will see more and less pears.
That is just CSS based.
An example of what you want to accomplish from a friend website redesign
shrink and wide the browser so you can see the effect
You can also use JQuery to moniter whether browser window is resized, through $(window).resize function. And you'll have to call details of the products shown either using Ajax or with iframe by reloading the page within iframe with more products.
The code to be written inside browser's resize method will be as follows.
$(window).resize(function() {
//Your code on resizing the browser.
});
