Question

I’m trying to initialise an array of Photos, and am doing so like this:

NSMutableArray *photoList = [[NSMutableArray alloc] init];
self.photos = photoList;

But when this line of code runs, I get this error:

'NSInvalidArgumentException', reason: '-[Project setPhotos:]: unrecognized selector sent to instance 0xee8e310'

I’ve spent about three hours trying to find a fix but couldn’t, can anybody tell me what to do?

It seems to me that you haven’t created a property photos and if you have then it would also seem that this property is not @synthesize‘d in your implementation, maybe you are using @dynamic, in which case it is up to you to create a - (void)setPhotos:(NSMutableArray*)photos; method
