UIActivityItemSource and Facebook?

Working with the UIActivityItemSource, I'm finding that Facebook won't take anything except an image or URL - is there any way to supply it with text? My code works fine with Mail, Twitter, etc. The Facebook and Messenger apps will display a supplied image, will extract an image from a URL in pre

NSBundleResourceRequest with Initial Install Tags not available immediately?

I've got an app, with a pre-built Core Data persistent store, that I'm trying to use with On-Demand resources, set up with Initial Install tags. Trying to use it on first run in the App Delegate, I'm finding that on a real device attached to Xcode, the resources are not immediately available on t

CloudKit queries for records with CKAssets - one or many?

I've got an app that displays 40-50 thumbnail images at a time via CloudKit. Right now it issues a CKQuery for each image when its corresponding UICollectionViewCell becomes visible. (Once I have them they are kept locally) I could launch 1 or 2 queries to retrieve the entire batch, which would o

Reusable Detail View Controller for UISplitViewController?

This seems too easy - seems to work great. Can anyone point out a defect with this approach? I want to reuse the same view controller instance as the detail view controller for a UISplitViewController - my experience is that constantly instantiating view controllers can be sluggish. Simply makin

Xcode warning from linking to a third-party framework in both app and in framework included in app?

I'm linking to the Parse.com frameworks in both my app and in a private framework of my own included in the app. This generates the linker warning below. Both the app and the included framework use objc[1735]: Class PFObject is implemented in both and . One of the two will be used. Which one i

Xcode 3.23 broke my code signing

Project that built fine for weeks fails to pass validation, won't run when installed. Ran Xcode uninstall, reinstalled from scratch, same deal. Other than randomly trying stuff, does anyone have a known working procedure for fixing this??? Hard to think of a less productive way to waste time.

Big Core Data, countForFetchRequest, and GCD

countForFetchRequest seems to bog down on really big collections of entities. For approx 170K entities it takes around 10 seconds on an iPhone 3GS to count them, which is a problem in a UITableView where you are trying to display a list of entities and associated counts. A GCD based solution, tha

Re: What is the point of a host-reachability test that doesn't test the reachability of the host?

Just to add another two cents on the unreliability of pings for determining reachability, if you are using the wi-fi service in certain airports, cafes, etc. some wi-fi providers will respond to a ping of anything, so it will appear you can reach any host, when in fact you can't reach anything exce

How to create a dial keypad with autolayout?

Core Data, Bindings, NSSearchField, and NSPopUpButton

NSDateFormatter timeStyle NSDateFormatterFullStyle for dates earlier than 1970?

NSDateFormatter (iOS) does not produce time zone names (or abbreviations) prior to January 1, 1970, instead shifting to the "GMT-08:00" style. Is this a bug or a feature? Judging from the tz database, it should be able to produce names prior to 1970 if I understand tz correctly. NSDateFormatter

Best Xcode machine mid-2019?
