you can register for UITextViewTextDidChangeNotification and trim the string received only to 250 characters if it is greater than 250 characters. You can disable editing the text view from IB.

can you give some example please? – Hiren Sep 30 '12 at 05:39
I don't have access to MAC right now.. so can't give you code... This notification is fired just after the text in textview changes so you can change it just after that, it pretty basic stuff. – Ankit Srivastava Sep 30 '12 at 05:50
i have tried but it's not called http://stackoverflow.com/questions/1328638/placeholder-in-uitextview – Hiren Sep 30 '12 at 05:53
placeholder is something else... what are you trying to do...? – Ankit Srivastava Sep 30 '12 at 05:56
i get the txt from server and i just place the text like placeTxt.text = [listDict objectForKey:@"desc"]; – Hiren Sep 30 '12 at 05:59
before setting the text you can check its length and truncate it if it's greater than 250 character, and why did you give me the link to the placeholder question...? – Ankit Srivastava Sep 30 '12 at 06:03
just for implementation like the link for notification – Hiren Sep 30 '12 at 06:05

You can do like as :

   UITextView *your_txtView;

if ([YourServerString length]>=250) {


    YourServerString = [[YourServerString substringToIndex:249] stringByAppendingString:@"..."];



}
your_txtView.userInteractionEnabled = NO;
your_txtView.text = YourServerString;
