It might seem something simple, but I still remember when I was beginning my life as an iOS developer and certain things were not exactly out of the box. UITextView’s support for multiple lines puts it into a complicate situation when it comes to┬áhandle the return key. Still, that’s something you can easily implement using a delegate method.

-(BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{
if([text isEqualToString:@”\n”]){

[textView resignFirstResponder];

return NO;
}
return YES;

}
