An Objective C Category Item Class and using NSLog with NSInteger EXC_Bad_Access

Hopefully people find this class useful its mainly for my own reference but I ran into a few issues when writing it and learnt alot along the way so I thought others might find it useful.Its just a simple objective c class for a table that is stored in SQLLite database, adding in

It uses the FMDB SQLLite wrapper. Jump over to github I recommend you use it I was previously writing my own code. https://github.com/ccgus/fmdb

When writing this I was overlooking a simple mistake and spent ages trying to figure out why my new getAll method wasn't working it appeared to be retrieving the data from the database but when I went to do something like

NSMutableArray *categoryList = [CategoryItem getAll]; NSLog(@"number of items is %@", [categoryList count]); <<--- %@ should be %i

This was throwing a Program received signal EXC_Bad_Access error on the NSLog statement and for the life of me I couldn't figure out why Turns out you can't use "%@" when printing a NSInteger you have to use %i. Which makes sense right! Since NSInteger is not an objective C class but its on data structure (I'm pretty sure I was thinking of NSNumber as its Objective-C class, a subclass of NSValue to be specific)
