Question

I have some code that sets a border around a UITextView. It builds correctly in one class; when I take that code and copy it to another class (changing the object name), it no longer builds, saying “Property ‘borderWidth’ cannot be found in forward class object ‘CALayer *'” (the same message for the other two lines of code). I have done a clean, re-build and nothing helps. Why is this happening? and how do I fix it?

- (void)viewDidLoad  {
[super viewDidLoad];

//--  draw box around notes field
orderNotes.layer.borderWidth = 1.0f;
orderNotes.layer.borderColor = [[UIColor blackColor] CGColor];
orderNotes.layer.cornerRadius = 4; 

}

Object “orderNotes” is defined as UITextView. There are no other errors.

Answer 1

You need to:

#import <QuartzCore/QuartzCore.h>

Otherwise, the layer property is not visible to you.
