fn textView_shouldChangeTextInRanges_replacementText( &self, text_view: &UITextView, ranges: &NSArray<NSValue>, text: &NSString, ) -> bool
where Self: Sized + Message,

Available on crate features UIResponder and UIView only.

Asks the delegate if the text at the specified ranges should be replaced with text.

If this method returns YES then the text view will, at its own discretion, choose any one of the specified ranges of text and replace it with the specified replacementText before deleting the text at the other ranges. If the delegate does not implement this method then the textView:shouldChangeTextInRange:replacementText: method will be called and passed the union range instead. If the delegate also does not implement that method then YES is assumed.

Parameter textView: The text view asking the delegate

Parameter ranges: The ranges of the text that should be deleted before replacing

Parameter replacementText: The replacement text

Returns: Returns true if the text at the ranges should be replaced.
