Question

It’s as simple as that.

Running Lion.

1. I just upgraded to XCode 4.4
2. loaded my most recent XCode 4.3 project file
3. commented out one @synthesize line of code
4. and errors abound. 🙁

Verified compiler is set to ‘LLVM 4.0’.

Then I did the same test but created a new project within XCode 4.4, and voila! Auto @synthesize works within a 4.4 project.

Auto @synthesize also seems to work on new properties added to the code. But existing old one generate an error.

Anyone else experience this?
Any other things I should check for?

I really want the auto generation features to work.

Thanks.

Answer 1

The Error isn’t the way you declare the property but in the way that you use it.

Auto-synthesized properties create a backing store with a leading underscore by default.

So in your code when you have a property declared as:

@property (nonatomic, strong) UILabel *sectorLabel;

and you auto-sythesize – something like this is being auto-generated for you by the compiler:

@synthesize sectorLabel = _sectorLabel;

Now you can access it through the the property:

self.sectorLabel;

Or, you can access the backing store directly with:

_sectorLabel;
