Solved. Sample code as below:-

(BOOL)textField:(UITextField )textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString )string {

if (textField == txtEmail) { if (txtEmail.text.length >= 12 && range.length == 0) { return NO; } if(![txtEmail.text containsString:@"@"]) { txtEmail.errorMessage = @"Invalid Email"; } else { txtEmail.errorMessage = @""; } }

return YES; }
