Objective-C basics - (Why NSNumber conforms to NSCopying protocol)

Hi, This may be very basic question. I am curious to know the details. what was the reason NSNumber conforms to NSCopying protocol. NSNumber is immutable class, Making a copy of NSNumber object returns the same reference. Is there any case where NSNumber returns the new object? if not, then

Re: Dynamic-width Collection View

I definitely remember feeling like there was a bit of a mismatch between the “declarative” feel of auto layout and the more procedural feel of all the necessary collection view layout overrides and whatnot. Bridging that gap was the main reason for all the shenanigans in that code (well, that an

Re: Dynamic-width Collection View

Peter, I really appreciate your feedback and did look at your solution last week. I kind of gave up on the justification issue since it looks like what I saw is "expected" behavior and didn't want to get into workarounds until I figured out the self-sizing cells issue. I looked at your code an

Re: Dynamic-width Collection View

Sorry if this is kind of a cheesy reply, but a while ago I believe we were speaking about “left-justifying” a collection view as well? I think I replied to that thread with a link to a very unattractive toy repo of mine on GitHub to illustrate the approach I’d taken with that. Anyway that repo doe

Re: Dynamic-width Collection View

The main issue is that the cell doesn’t (and shouldn’t) have any idea about what size the collectionView is. You could actually use the delegate though (which has a wider view) and provide the size that way. That said, I did additional research and found other people with your issue. Relevant

Re: Dynamic-width Collection View

Jonathon, Thanks for the feedback. A question that comes to mind is, what about making cells the same size as the collection view requires going through subclassing the collection view layout? Apple documentation IMPLIES this should work. It even documents that developers should use preferredL

Re: Cocoa File Close Notification

Have you considered using a dispatch source? You might have to do some manual checking when you get a notification about activity with your file, but it might be suitable to your needs. Here's a link I was reading: http://stackoverflow.com/questions/11355144/file-monitoring-using-grand-central-

Dynamic-width Collection View

I'm currently trying to implement something that seems basic but has been driving me nuts: making a Collection View with cells that are dynamic-width and height at runtime. I was able to accomplish this with Table Views by using the dynamic height constant. Following Apple documentation, I set
