I'm not able to find any inbuilt property for this. Is there a way by which I can manually achieve this? How to set maximum length of a NSTextField without overwriting the last character ? They shouldn't be able to enter the next character after maximum limit is reached.

Hope this will help you,

-(void)controlTextDidChange:(NSNotification *)obj{
  if([Textfield .stringValue length]>8)//you can set the maximum 
  {
      [[Textfield currentEditor]deleteBackward:nil];
  }
}

**Note:Set your textfiled's delegate to self. Eg:textfiled.delegate = self;*

NSTextField delegate have a function that you can use to check length of text

- (BOOL)textView:(NSTextView *)aTextView shouldChangeTextInRange:(NSRange)affectedCharRange replacementString:(NSString *)replacementString
{
}

If you don't want to apply this delegate function every where you use NSTextField. You can subclass a CustomTextField.

Hope this help.
