Product Version: Latest

Please give a brief summary of your issue:
We only want to support one font (Arial) on iOS. The default is current is Helvetica. How would I set the default and remove the ability to select a different font? Users call select the font from a free text or a call out annotation.

Hi Jack,

You can achieve this by subclassing the PTAnnotStyle class and overriding the availableStyleKeys property. Then removing the “AnnotStyleKeyFont” key from the list of keys.

To override a class have a look at this guide: PDFTron Systems Inc. | Documentation

The code would look something like this:

class CustomPTAnnotStyle: PTAnnotStyle {
    override var availableStyleKeys: [PTAnnotStyleKey] {
        get {
            return super.availableStyleKeys.filter { key in
                key != PTAnnotStyleKey.font

Please let us know if this works for you.

Best Regards,
Sahil Behl.
