Question

I want to replace the text in UITextView text in selected range. This is my question. Here i mention what i did? and what i want to do?. I have an UITextView and entered the below text in textview.

Ask question here, i have saved the range in of the text in textview. The text range is {17, 0}. I take the NSRange in -(void) textViewDidChange:(UITextView *)textView delegate.

Now i want to replace the text question with answer and i want to replace the text here with them. The UITextView.text look like this,Ask answer them` after replaced the texts.

How can i replace the texts with the selected ranges? Can you please help me? Thanks in advance.

Well… I’m not sure to understand correctly what you’re trying to do, but if your goal is to change some characters in a selected range you can follow these steps:

Get your UITextView content and put it in a NSString:

NSString *textViewContent = textView.text;

Change the characters in the range you want:

NSString *newContent = [textViewContent stringByReplacingCharactersInRange:range withString:replacement];

Replace old content with new one:

textView.text = newContent;

Anyway if you just want to replace Ask question here with Ask answer them the fastest solution is just:

textView.text = @"Ask answer them";
