Xcode 4.6.2 Lion 10.7.5
Programming with Objective-C seems to indicate I can do this:
#import <Cocoa/Cocoa.h>
#import "Cell.h" //My sub-class
@interface Document : NSDocument
@property Cell *protoCell;
@end
and this (i.e. no need to @synthesize):
@implementation Document
- (id)init
{
self = [super init];
if (self) {
protoCell = [[Cell alloc]init];
// Add your subclass-specific initialization here.
}
return self;
}
……
@end
but the compiler tells me
Use of undeclared identifier 'protoCell'; did you mean '_protoCell'?
If I do refer to the ivar using the internal reserved form _protoCell
the compiler is happy.
What is my lack of understanding? Why am I not allowed to use
the getter protoCell as indicated in the documentation?
TIA
Peter
