Answer 1

Dan's answer is manually changing the text. It's not playing well with UITextView's UndoManager.

Actually it's very easy to insert text with UITextInput protocol API, which is supported by UITextView and UITextField.

[textView replaceRange:textView.selectedTextRange withText:insertingString];

Note: It's selectedTextRange in UITextInput protocol, rather than selectedRange

Answer 2

This is what I use with a custom keyboard, seems to work ok, there may be a cleaner approach, not sure.

NSRange range = myTextView.selectedRange;  
NSString * firstHalfString = [myTextView.text substringToIndex:range.location];  
NSString * secondHalfString = [myTextView.text substringFromIndex: range.location];  
myTextView.scrollEnabled = NO;  // turn off scrolling  

NSString * insertingString = [NSString stringWithFormat:@"your string value here"];

myTextView.text = [NSString stringWithFormat: @"%@%@%@",  
                 firstHalfString,  
                 insertingString,  
                 secondHalfString];  
range.location += [insertingString length];  
myTextView.selectedRange = range;  
myTextView.scrollEnabled = YES;  // turn scrolling back on.

Answer 3

The simplest way (but it won't replace selected text) is to use the insertText: method:

[textView insertText:@"some text you want to insert"];

UITextView conforms to UITextInput which itself conforms to UIKeyInput .

Answer 4

Here is the Glorfindel's answer in Swift3. The text its inserting here it pulls out of the clipboard.

if let textRange = myTextView.selectedTextRange {
   myTextView.replace(textRange, withText:UIPasteboard.general.string!)
}
