Hey so i have a UITextView inside a UIView which i dynamically load with content. I'm resizing the height of the text view using this solution

I have auto layout turned off for this to work (other solutions like sizeToFit() were not working with auto layout ON) but when i do this, even though all the content of the text view does get rendered, it overflows the bounds of it's containing UIView.

I tried to use the same solution that worked for the text view on it's container too, but that didn't do anything.

One thing that DOES seem to work is:

newFrame = containerView.frame
newFrame.size.height = textView.frame.size.height
containerView.frame = newFrame

But this isn't what i need coz i'll also have a couple of labels in this container view so it's height can't be the same as the text field's.

Is there a way to fix this without turning auto layout on again? (Will turning auto layout on even help?) And if turning auto layout on will fix this, then is there a way to keep the dynamic size of the text view (coz turning it on will break that)?

I'm very new to this. Appreciate the help.

Oh and i'm actually developing a tvOS application, not an iOS one. Dunno if that makes a difference.

EDIT:

Here's the actual code:

@IBOutlet weak var container: UIView!
@IBOutlet weak var label: UILabel!
@IBOutlet weak var text: UITextView!

override func viewDidLoad() {
    super.viewDidLoad()

    print(text.frame.origin.x, text.frame.origin.y)

    text.scrollEnabled = false

    text.text = "bla blah blah blah boo boo boo boooooo boo blah yo yo yo yo yo hello"
    let fixedWidth = text.frame.size.width
    let newSize = text.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.max))
    var newFrame = text.frame
    newFrame.size = CGSize(width: max(newSize.width, fixedWidth), height: newSize.height)
    text.frame = newFrame
}

This dynamically expands the text view when the content changes. Adding:

newFrame = containerView.frame
newFrame.size.height = textView.frame.size.height
containerView.frame = newFrame

resizes the container UIView, but makes the text.frame.origin.y of the text view 0. So adding any other elements to the container just overlaps with the text view.

You can achieve this with both autolayout or framing. If you are using frame then you need to take into consideration the height of all other components in the containerView. Lets say you have 3 Labels, 1 above the textview and 2 below it having 15 points has vertical distance between each, then your containerView height should be:

newFrame = containerView.frame
newFrame.size.height = 15 + label1.frame.size.height + 15 + textView.frame.size.height + 15 + label2.frame.size.height + 15 + lable3.frame.size.height + 15
containerView.frame = newFrame

With Autolayout you have to set proper vertical constraint among the components to resize accordingly.

  • So i have to actually hardcode the padding i've got between my different components and like add them together? That isn't very clean right? I didn't really get the vertical constraints bit. Is that something i can use on UIView to make it resize dynamically? – alokraop Apr 26 '16 at 11:16
  • Its not clear but before Autolayout that was only the option, You can hardcord the constant part directly to 45. For Autolayout you can go through https://www.raywenderlich.com/110393/auto-layout-visual-format-language-tutorial – Arun Gupta Apr 26 '16 at 11:22
  • hey so the adding heights with padding thing didn't work. Turns out assigning the height of the text view to the container somehow changes the text view's origin, so it will overlap with any other controls above it. No idea why though. – alokraop Apr 26 '16 at 11:39
  • Please update your question with the code,how you are setting up UI and dynamic updating of textView – Arun Gupta Apr 26 '16 at 11:43
