How to use both vertical and horizontal ScrollView in Xamarin iOS ?
I am using CollectionView but with it I only get one scrollview working at a time.
It's because it's nature of collection view, you can make it scroll in one direction at a time i.e. either horizontal or vertical. What you exactly want to achieve that you have not mentioned. if you are going to use collection view inside the scroll view, you have to manage it properly.
The best solution would be use a UICollectionView for the horizontal
scroll and the UITableView for the vertical scroll.
But if you want to make it work only using UICollectionView you have to use Subclassing UICollectionViewLayout.
here is link you can refer to make it work, hope this might help you:

I'm generating Views inside FlexBox layout by pressing the Start button. As you can see every item on even line has random size. It works almost as it supposed to be but there is a problem, I need to get rid of vertical gaps between two vertically adjacent views. I've tried all properties of Flex Box Layout but didn't find one that can help to solve my problem. I will be happy if you help me to solve this problem.
I've solved this problem. If you have the same task you should use Relative Layout and its' flags inside your android code. It'll give you all control under the positions of Views. If it will be necessary I can expand this answer to provide more detail.

I am using PanResponder class in react native to achieve this functionalities.
for scrolling I am using scrollTo() . But I am failed do this. I like to share my code but it was too bulky and not understandable.
So my question is Is anyone have any code to achieve this. or Is there any libraries available?
Please help me
Use scrollToEnd({animated: true}) to go the bottom of scrollView in react-native.
From doc.s of facebook https://facebook.github.io/react-native/docs/scrollview#scrolltoend
scrollToEnd()
If this is a vertical ScrollView scrolls to the bottom. If this is a horizontal ScrollView scrolls to the right.
Use scrollToEnd({animated: true}) for smooth animated scrolling, scrollToEnd({animated: false}) for immediate scrolling. If no options are passed, animated defaults to true.
Hey there I have been wanting to implement a layout that is responsive and scaleable. I have been looking into the Linear Layout with the layout_weight attribute but to no success.
Could you give me a hint or point me in the right direction as one would achieve a responsive layout similar to this one in the picture?
After some intense search I found this can be achieve by a couple of ways. Either by using GridLayout or GridView or by just manipulating LinearLayout with elements inside it.
I am new to Xamarin IOS and I have a problem with creating nested layouts in IOS as like in Android(some text controls and a list view) . I added a tableview but not sure how to add some text and image controls in a view and add the tableview below the text and image controls. Also I am using ViewPager in Android and is there an equivalent control that I can use in IOS?
Yes, you should use UIScrollView and enable paggin there. The only issue that you need always to set the ContentSize for it, to make it scroll properly. So you should set the common Size of inner content.
You should check out monotouch.dialog for rapid tableview development. Once you get the hang of it, it makes creating tables a lot easier.
I have gotten UIWebView inside UIScrollView to work, so far anyways, and I have just seen mention on Apple's site that doing so is not advised.
So OK, what's the alternative? I need to display web pages, and I need them to be scrollable, such that if the user swipes leftward then an entirely different page appears coming in from the right. And a reverse situation with swiping rightward.
How is that done without putting UIWebView inside UIScrollView?
Thanks.
Well, you need the UIWebView, which has indeed many features of a UIScrollView, to be able to scroll not only up and down, but also to left and right.
Also, scrolling with two fingers is a no-go, for scrollable elements within a web page, such as textareas can only be scrolled with two fingers.
Three fingers is also not so good because that's not convenient for people with thick fingers...
So my suggestion is that you add a UIGestureRecognizer to your UIWebView and look out for a swipe gesture. Then handle the switching of pages accordingly with animations.
