I have a tableViewController utilizing an NSFetchedResultsController to display data. The Cell's primarily consist of textView's which resize based on content. The tableView uses automatically sizing cells.
Everything works fine except that when the tableView is first presented, the cells can be seen resizing horizontally into place. Subsequently when the tableView is presented the cells are sized correctly.
All other behavior is normal. When cells are dequeued they are sized normally and do not resize as they appear.
The cell's are subclassed in the normal way and AutoLayout is used. I have set all the priorities for the content of the textView to 751 in storyboard.
The text is added to the cell in cellForRowAtIndexPath with simply cell.textView.text = someText
Just wondering if I need to call tableView.layoutIfNeeded() or any other methods prior to initially displaying the tableViewController.
I am initializing the NSFetchedResultsController in viewDidLoad
After fetching data from your api, you need to call
tableView.layoutIfNeeded()
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 application that I'm developing in swift. I added a UITableView in a ViewController. The UITableView frame is going out of view in width. I have already checked that the width of TableView in Interface Builder is within the view.
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.
I have UITableView and UIView(used to show image slideshow) inside UIScrollView. The tableview is dynamic and i want to automatically adjust height of table view to show all the cells(and disable scrolling of tableview) and scrollview should show both slideshow and tableview and could be scrollable, I know how to do this with code but i want to know if is possible to do in Interface builder(without using iOS6 auto layout) using previous(iOS5 and early) autoresize method in the xcode size inspecter tab(see image)
I think this is hard to do only using interface builder.
You can set your objects via interface builder. But for maintaing scrolling conditions you need to do it programmatically. Also for table view height to be dynamic you need to be done programmatically.
