I have a custom UITextfield that is x-centered to its superview via a constraint. It also has a height-constraint and a nice thin line right under the text that has the same width as the textfield itself (like I said: custom).
I now want to keep the UITextfield centered while editing its content, adjusting itself in width to its string content.
What right now happens is that it keeps its width while editing, cropping its overlapping content.
My code is kind of
// on textfields editing change event
#IBAction func nameFieldEditingChanged(sender: AnyObject) {
// set width of textfield to width of textstring
checkUserNameTextfieldWidth()
}
func checkUserNameTextfieldWidth(){
println("checkUserNameTextfieldWidth \(userName.text) / \(userName.frame.size.width) / \(view.bounds.width)")
// something has to happen here I guess...
}
Thnx!
You have to use UITextView instead of UITextField and apply its sizeThatFits method (see this response)

I have a TextView as shown below
I am not able to scroll the text view , I have added UITextViewDelegate in UIViewController class as well as set isUserInteractionEnabled property in textViewDidBeginEditing
func textViewDidBeginEditing(_ textView: UITextView) {
textView.backgroundColor = UIColor.lightGray
textView.isEditable = false
textView.isUserInteractionEnabled = true
textView.isScrollEnabled = true
}
What did I need to do?
Also, the scrolling is enabled in attribute inspector
This issue has occurred because the actual UITextView's size was more than screen size as shown below
The real answer is that the UITextView needs its content frame height inferior to its content size height to be able to scroll.
In your case, the content frame height is equal to the content size, so it doesn't scroll.
You just have to set the leading left, trailing, top space and bottom space to the View, but first make sure the Text View is smaller than the actual View (parent).
It starts to get complicated when you have a UITextView on a UIView which is either a view on a UIScrollView or directly on a UIScrollview.
The best thing to do, is to give each of them their own actions when scrolling.
Firstly, make sure you have all of your delegates for EVERYTHING set.
Make sure your UITextViews are not user restricted for what they don't need to be.
What I have to do in one of my published apps is this👇
func scrollViewWillBeginDragging(_ scrollView: UIScrollView)
{
if scrollView == textView1
{
// Do something if you actually want to, or just let textView1 scroll as intended
}
else if scrollView == textView2
{
// Do something if you actually want to, or just let textView2 scroll as intended
}
else if scrollView == zoomingScroll
{
// Do something if you need to or leave it
}
else
{
// Do something with all the other scrollable views if you need to
}
}
I stuck with scrolling content inside UIScrollView in my tvOS app.
I have scrollView with height = 400 and width = 400. Inside this scrollview I have non-scrollable UITextView with height = 800 and width = 400. So I want to scroll this text.
But my scroll view is not scrolled, I don't see any scrolling indicators and also my scrollView have isFocused value = false. How can I solve this problem?
p.s. update I created separate ViewController (image below).
It have black ScrollView and white view with big height with label in the middle of it. ScrollView has fixed width and height and there is no scrolling for some reason! I even didn't connect any separate class - just created it from Interface builder.
UIView isn't focusable by default (and as such in tvOS it can't be scrolled) . You have to subclass it to override canBecomeFocused:
class myUIView: UIView {
override var canBecomeFocused: Bool {
return true
}
}
Then in your example use the class myUIView instead of UIView for your long white view. Setting the right constraints you wouldn't need to design the views out of the controller view boundaries in IB either. Check this answer with the linked gist to see how to build the constraints.
I think you can use the
func gestureRecognizer (_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool
method to judge the view and scroll it
According to the view you touch to do something to intercept
There is some way to fix your problem.
Please check your scrollview in storyboard, is your scrolling or vertical indicator is checked?
U can make your textview scrollable if u just want to scroll the textview content
There is problem in your constraint, you need to cleary add the height, vertical space top, vertical space bottom from your textview to your scrollview.
Hope these advice can help you
So you have to set the scrollview's content size larger than the scrollview bounds, so you should set contentsize to (400, 800), probaly in you xib
I am attempting to set the contentInsets to zero for my textView that I place inside my tableViewCells so that I can align my text with the label and imageView bubble. My current implementation looks like this.
I adopted the solution in this post but does not seem to work for my case.
Blank space at top of UITextView in iOS 10
The solution in the above post is for uiviews but mine is in a tableViewCell, which automaticallyAdjustsScrollViewInsets is not available in tableViewCell.
Any help here pls?
Setting contentInset to zero will not work since it's applied to UIScrollView.
The spacing that you want to remove is actually controlled by NSTextContainer inside of UITextView.
To remove the spacing just put this in your cell (for example inside awakeFromNib):
override func awakeFromNib() {
super.awakeFromNib()
// Removes UITextView inner spacing
textView.textContainerInset = .zero
textView.textContainer.lineFragmentPadding = 0.0
}
Title should read: Automatically adjust width of the containing NSWindow of a view based NSTableView based on NSTableCellView's NSTextField content intrinsic content size.
A bit like this other question, I would like to implement an autocompletion NSWindow with an NSTableView inside it that adjust to the width of the length of the available autocompletions implemented as NSTextField inside an NSTableCellView. Each autocompletion should obviously be displayed on one line...
The previous question has been answered but was only related to the hight of the NSTableView. I would like to know how to do the "same" for the width. I would like to implement the solution as much as possible using auto layout.
I've tried to set the horizontal "Content Hugging Priority" and the "Content Compression Resistance Priority" to the maximum of 1000 for each view element participating in the final display of the NSWindow. I was thinking that the intrinsic content size of the NSTextField would force all other elements to adjust but it does not work.
Setting the NSTableColumn width does not work either since the NSClipView of the NSScrollView is not modified by this width: the NSScrollView adjusts and creates horizontal scroll bars to cover the entire "document".
Here is a link to a sample project to demonstrate the problem:

Any help would be greatly appreciated!
I fixed the problem using this code with the scrollViewWidthConstraint being an IBOutlet to the NSScrollView width constraint, localTableView being an IBOutlet to the NSTableView and tableColumn being an IBOutlet to the NSTableColumn (the only one in my case).
Note: The linked project on GitHub has been updated with the changes.
override func viewDidLoad() {
super.viewDidLoad()
self.updateTable()
}
func updateTable() {
localTableView.reloadData()
var computedWidth: CGFloat = 0
for var row = 0; row < 10; row++ {
let tableCellView = self.tableView(localTableView, viewForTableColumn: tableColumn, row: row) as! NSTableCellView
computedWidth = max(computedWidth, tableCellView.textField!.intrinsicContentSize.width)
}
scrollViewWidthConstraint!.constant = computedWidth
scrollView.needsUpdateConstraints = true
}
I want to change the textField height as the user types in it.
How can I do it?
I don't want to use a TextView.
Every UITextField comes with an action Editing changed, you can drag and drop as an action to your class.
In this method, you can probably change the constraint that defines the height of the UITextField. Make sure to call self.view.layoutIfNeeded() to update the constraint you just changed. For example:
#IBAction func editingChanged(sender: AnyObject) {
editTextHeight.constant += 2.0
self.view.layoutIfNeeded()
}
