Convert selectedTextRange UITextRange to NSRange
Here's a Swift extension based on the answer by Vitaly S.
extension UITextInput {
var selectedRange: NSRange? {
guard let range = self.selectedTextRange else { return nil }
let location = offsetFromPosition(beginningOfDocument, toPosition: range.start)
let length = offsetFromPosition(range.start, toPosition: range.end)
return NSRange(location: location, length: length)
}
}
Swift 4
extension UITextInput {
var selectedRange: NSRange? {
guard let range = selectedTextRange else { return nil }
let location = offset(from: beginningOfDocument, to: range.start)
let length = offset(from: range.start, to: range.end)
return NSRange(location: location, length: length)
}
}
You need something like this:
- (NSRange) selectedRangeInTextView:(UITextView*)textView
{
UITextPosition* beginning = textView.beginningOfDocument;
UITextRange* selectedRange = textView.selectedTextRange;
UITextPosition* selectionStart = selectedRange.start;
UITextPosition* selectionEnd = selectedRange.end;
const NSInteger location = [textView offsetFromPosition:beginning toPosition:selectionStart];
const NSInteger length = [textView offsetFromPosition:selectionStart toPosition:selectionEnd];
return NSMakeRange(location, length);
}
