I want to make a full screen scrollview with various views in it but also have a tableview in it.
The thing is, I don't want the tableview to "reuse" views.
I am using auto-layout.
People keep asking why. Here is why:
I want the scrollview to keep growing in height as cells are added to the tableview. (using storyboard) This is something I want to do. Stop "suggesting" a "better" way because I know the "better" way. I am asking for this way.
For example:
As cells are added to the tableview, the entire scrollview keeps growing.
Hope you are using autolayout, considering this i guess you already added constraint from the bottom of tableview to the uiview below it and also add a height constraint to the tableview. Make a IBOutlet of this height constraint. now write a method that would calculate the height depending on number of items you have to show for the tableview like
func calculateTableViewHeight() {
heightConstraint.constant = YOUR_CELL_HEIGHT * NO_OF_ROWS
}
Call this method after tableview.reloadData(). And also don't for get to set the scrolling for the tableview to false

here is my design structure
I was wondering about creating a horizontal and vertical scrolling tableview. I have tried a tableview inside a scrollview but I failed miserably. What to do?
I use swift4 but I wanted to do in storyboard.
The nature of content is like an excel sheet with lots of horizontal and vertical scrolling rows and columns of data.
Actually you can do this using a hack. Put the tableView inside a scrollView. Then you should give a dynamic width to the tableView by specifying a width in storyboard for tableView or any child view of that scrollView(So we get the horizontal scrolling).You have to adjust some constraints depending on your requirement
Mine worked fine but as many users have said try a collection View if its easy
Note. There is a default scrollView within a tableView, So adjust your height of tableView in a way so the scrollView of tableView work and not the parent scrollView, while scrolling from top to bottom
Instead of using TableView try using collection view, there you can use horizontal and vertical scrolling using storyboard?
Try to use collectionview instead of tableview.
If your requirement demands use of tableview anyhow, then you can use tableview within scrollview.
In tableview within scrollview approach, you need to distinguish your parent scrollview as well as tableview's scrollview. Try to differentiate parent scrollview and tableview's scrollview with different tags. Because both scrollview will call delegate methods of viewcontroller, if implemented. Just check tag of scrollview in all delegate methods of scrollview and perform action accordingly.
As per my understaing you want a view which you want vertical scroll view and horizontal inside it.
So here my suggestion is to use UITABLEVIEW for vertical scrolling and UICOLLECTIONVIEW for horizontal scrolling inside tableview
Both will work fine
I have a problem with a UITableView not detecting touches.
In an iPhone-only app, I have a UIViewController, which containts:
UIScrollView
UIView (let's say a content view)
Some labels
UITableView (last)
The labels have a dynamic height, because they contain some text that I must retrive from the web, so I'm using auto layout.
I'm setting the content size of the UIScrollView inside the viewDidLayoutSubviews method, and I'm doing this by summing UITableView.frame.origin.y and its height.
Here comes the problem: when the labels contain only some words and the UITableView does not exceed the iPhone screen size, everything works ok. But when they grow, and the UITableView gets pushed down, when I scroll down I can't click on the cell anymore. Also, if when loading the view the table is half visible and half not, I can click the visible cells, but if I scroll down, I can't click the others.
I'm using swift 2 and Xcode 7.
Here is an example:
Clickable:
Unclickable:
Do the following thing:
yourView.clipToBounds = true
Now, if UITableView does not appears means your UIView is not same bigger to hold down UITableView.
Make sure that your UIView height is bigger to hold the contents in it and then try to tap on it.
Updated:
If you are using AutoLayout, then do the following thing.
Give the fix height to UIView
Take the outlet of height constraint of UIView
Now, in viewDidLayoutSubviews change the constraint of UIView to UITableView contentSize height.
self.heightConstraint = self.tableView.contentSize.height
Let me know, if this helps!
Adding some info to the #Rémy Virin's answer here:
From Apple Documentation, you shouldn't embed a UITableViewinside a UIScrollView.
Important: You should not embed UIWebView or UITableView objects in UIScrollView objects. If you do so, unexpected behavior can result because touch events for the two objects can be mixed up and wrongly handled.
Addition:Solution Since you want to scroll the content above table also, the one solution is place a Header View for the Table and place the Content over there to make it Scroll along the Table View.
If you use Autolayout, no need to specify contentSize to UIScrollView as it will automatically expand by taking the height of its subview.
In your case, increase the height of the Base UIView (content view as mentioned by you) which holds the tableView when the tableView height increases.
UITableView becomes unresponsive when it extends below its container view.
I have a table with different cells and I need to add a scroller view with special UI in some cells:
I need to develop the UI which you can see in section 0.
So my questions are:
How can I add a scroller view?
How can I load data only for those items which are shown right now?
How can I change the width of "Line" column after scrolling to the right?
I'll answer as best I can with some starting pointers for you...
You need to subclass UITableViewCell and in your subclasses drawRect method you should add a UIScrollView to the contentView.
Not totally sure what you mean here, please expand.
In your new table cell, set it as the delegate of the scroll view you implemented, then you''ll get callbacks when the scrollview scroll with the contentOffset value, which you can use to calculate how much to grow or shrink the line items.
I need to achieve layout shown below. There are UIView and UITableView inside UIScrollView:
UITableView should be aligned right at the bottom of UIScrollView
UITableView should not have scrolling, so it's height should be adjusted according to content.
Row count is not static value.
Here are the constraints of UITableVIew:
If I understand AutoLayout correctly, everything should be fine, but as result I get UITableView's height to be 0. What's wrong with this setup?
I don't know what you are displaying above the UITableView but the normal setup for displaying something, that is above the tableView and scrolls with the tableview would be to use a UITableView (It is a Subview of UIScrollview and thus handles the scrolling itself) and add the things that you want to display above it as a tableHeaderView to your tableView.
The scrollView, which is there with UITableView dose not change it's size.
So I have a UITableView, where Cells are added by the User. Right after adding these cells, I'm calling
[self.tableView reloadData];
Now the tableView shows the new cells added by the User. fine. But, if the tableView get's larger, if it's too big to show everything in the view, it doesen't change the size of my scrollView. I have no scrollView in the view, aside from the "normal" scrollView, which comes with the UITableView. So I can't scroll to the last row, because the scrollView is "too small".
Is there anything I forgot? I'm thinking of something like
[self.tableView.scrollView reload];
I'm using the same concept in another class: The user is able to add cells and they're shown. But in the other class the scrollView "resizes" correctly.
I assume that you have table inside a scrollview. You need to change content size of scrollview after adding cells. Height of content size should change according to content in scrollview so that you can scroll through whole content.
Updated answer:
I think your tableview's frame is larger. It is crossing window's bounds. Try minimizing tableview's height.
