Consider two entities in a many-to-many relationship: Library and Book. In a
NSFetchResultController backed UITableView, I like to show all the books from
one library, so I constructed the following fetch request:
NSFetchRequest *fetchRequest = [NSFetchRequest fetchRequestWithEntityName:
Two things:
1. No, doing a string comparison with contains (and case and diacritical
folding active) is one of the slower kinds of string comparison. Straight
equality should be much faster.
2. You say that there are two entities, with a relationship defined. Why,
then, are you doing a string
I have a Document whose file type is a package and potentially contains a
few thousand files. My test case is about 7500 files (mostly images).
I am using
-(NSFileWrapper *)fileWrapperOfType:(NSString *)typeName error:(NSError
**)outError
The problem is that when there is a very small change
You are right about the [cd], which is not supposed to be here, blame it on
poor copy-paste skills.
So how can I fix the predicate to compare entities?

I think the point I was trying to reach was that your next step is to
investigate what is taking the time. IIRC there’s a NSURL attribute key you
can use to retrieve a file’s inode

I have to add a variable number of NSSliders to a custom view, (although,
probably no more than eight). I’d like these items centered within the view,
but am unsure how to achieve this. I know I could probably “do the math” and
just calculate the position of each as its added, but I thought I
