How do I update PDFViewCtrl to reflect a change in field value?

[Support]

Q:

When trying to change value of a checkbox by code, the appearance does not refresh.

For example in iOS:

TRNField *field = [self.docToOpen GetField:@"SMP"];

[field SetFlag:e_read_only value:NO];

[field SetValueWithBool:YES];

[field RefreshAppearance];

---------

A:

 

After you call RefreshAppearance, you should call one of the variants of PDFViewCtrl's Update method:
