Uitextview Font to Always Be Fixed Size

UITextView font to always be fixed size

Coding

var fontSize : CGFloat = 12.0 // DEFAULT SIZE

In your ViewDidLoad

if UIDevice().userInterfaceIdiom == .phone {
    switch self.view.frame.size.height {
    case 480:
        fontSize = 12.0
    case 568:
        fontSize = 14.0
    case 667:
        fontSize = 16.0
    case 736:
        fontSize = 17.0
    case 812:
        fontSize = 18.0
    default:
        print("unknown")
    }
}
else if UIDevice().userInterfaceIdiom == .pad {

    fontSize = 20.0

}

Then apply this fontSize, wherever u need.

Storyboard

Select UITextView, in Attributes Inspector area, + (plus) symbol is near to Font. By default it will work for iPhone devices. For iPad, Change change size classes to Regular width and Regular Height wR hR . For, that U can increase font size.

UITextView fix character width

As far as I know, Courier New is the only fixed-width font shipped with iOS.

Also, you can always import custom fonts to your xcode project which you know are fixed-width. Here is how: Embed Custom Font in iOS

How do I size a UITextView to its content?

This works for both iOS 6.1 and iOS 7:

- (void)textViewDidChange:(UITextView *)textView
{
    CGFloat fixedWidth = textView.frame.size.width;
    CGSize newSize = [textView sizeThatFits:CGSizeMake(fixedWidth, MAXFLOAT)];
    CGRect newFrame = textView.frame;
    newFrame.size = CGSizeMake(fmaxf(newSize.width, fixedWidth), newSize.height);
    textView.frame = newFrame;
}

Or in Swift (Works with Swift 4.1 in iOS 11)

let fixedWidth = textView.frame.size.width
let newSize = textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat.greatestFiniteMagnitude))
textView.frame.size = CGSize(width: max(newSize.width, fixedWidth), height: newSize.height)

If you want support for iOS 6.1 then you should also:

textview.scrollEnabled = NO;

Scaling UITextView And Font Size Change

The Affine Transform scaling factor is applied to text like anything else. So the onscreen text size should be the nominal textsize times the scaling factor. I.e., a 22px typeface zoomed by pinching to 1.25 scale would be 22 * 1.25 = 27.5px typeface.

Therefore, to keep the text size unchanged, you'd have to do the reverse: In your pinch recognizer, redraw the text in a typesize that is the nominal size DIVIDED by the scaling factor. Hence, draw 22px type at 22/1.25 = (about) 18px fontsize - which when scaled would be close to your original 22px size.

Clearly rounding is a potential issue, and you need to ensure the views of the text objects actually get redrawn. Does this help?

UITextView - setting font not working with iOS 6 on XCode 5

The issue was caused by the editable property being false in the Storyboard. I have absolutely no idea why this caused the font to remain unchanged - and only on iOS 6.

iOS - i want to change UITextView Height from single row to some fixed hight when i enter the text in swift3

You can always increase the frame of the textView to a fixed height on editing start (textViewDidBeginEditing), if you really wish to have it fixed.

But that would mean if user fills it up again, it would stay that way.

You could also track editing changes (editingChanged) like this:

func textViewDidChange(_ textView: UITextView) {
    let width = textView.frame.size.width
    let height = CGFloat.greatestFiniteMagnitude
    let textViewSize = textView.sizeThatFits(CGSize(width: width, height: height)
    var textViewFrame = textView.frame
    textViewFrame.size = CGSize(width: width, height: textViewFrame.height)
    textView.frame = newFrame
}
