As far as I know, since XCode 4.4 the @synthesize will auto-generate the property accessors. But just now I have read a sample of code about NSUndoManage
Thanks for clarifying that. I had a similar problem.
@synthesize firstAsset, secondAsset, audioAsset;
@synthesize activityView;
So now, having commented them out, I went through and replaced each occurrence with, for example
self.firstAsset It seems I could also use firstAsset, but I find I miss seeing the "" too often.
