Hi All,

I’m about to add some animations to my game and was wondering if any could give me some advice on the implementation given my App. This is for iOS Landscape only at present but I am intending on doing a Mac version too, so if it can be made as compatible as possible that would be good.

The App is a Board Game, there are two main views, the left had side is a Player Area and the right hand side is the Board. The View Hierarchy is something like this:

	RootView
		LeftAreaView
			BoardView
				CellView’s (81 in total - 9 x 9).
		RightAreaView
				BagView 
				ScrollView Containing the Host layer’s current Pieces
				Scroll View Containing the Player has the current turn.

The way the game works is that Players pick pieces at Random from the Bag - the Actually “Picking” is done by the GameEngine and the View Controller gets sent a “Player X picked Piece Y” type message. When this occurs I want to Animate the piece Dropping from the “Bag” into the Players “Stash” (One of the Scroll Views). When a player makes a Move, the View Controller gets sent “Player X Moved Piece Y into Cell X” type message, in this case I want to animate the Piece being removed from the “Stash” and Placed on the board.

What is the best way to achieve this? Do I use CALayer?

Yup, I would recommend using CALayers for the whole UI, pretty much. Back when Core Animation first came out I wrote a framework for building board/card games:

https://bitbucket.org/snej/geekgameboard

It hasn’t been updated since 2011 so it probably needs some fixes for API changes, but I still think the basic design is pretty well thought out. The goal was that you could implement a simple game UI in <200 lines of code, and there are examples included for checkers, tic-tac-toe, Klondike solitaire, and a few others.

Printing NSTextView puts text in middle of page

tridiak

#49

Printing a NSTextView centres the text (if it is less than one page in size) vertically in the page, as opposed to the top.

What do you need to do to fix this?

let tv = NSTextView()

tv.textStorage?.append(ats)

var npo = NSPrintOperation.init(view: tv);

tv.frame.size.width = (sampleViewScroll.documentView?.frame.size.width)!;

tv.frame.size.height = 20000; // or some large number

npo.run();

The attributed text (ats) is valid (displayed in a visible NSTextView).

Do I need to calculate the size of the text and set the margins?

Or is there a justification setting I am missing?

TIA

Where did you find this info? I've seen mention of them, but never an official type doc that lists them.

General information on format specifiers is here:

https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html

I use %td for NSInteger and %tu for NSUInteger. The 't' is a length modifier specifying that a following d, o, u, x, or X conversion specifier applies to a ptrdiff_t or the corresponding unsigned integer type argument. That allows you to use the same format specifier for both 32- and 64-bit platforms, get the correct results, and avoid compiler warnings.

My guess is that it asymmetric for historical and/or compatibility reasons. There’s also something about the Finder storing a “.Localized…” named file inside the bundle, but I don’t know if that’s still a current thing.

But at least you have a way forward that’s set-and-forget?

It never reads Base.lproj, even if the system language = Localization native development region = CFBundleDevelopmentRegion

The problem is that Xcode (obviously unaware of this Finder peculiarity) does NOT allow English as an additional localisation (because the development region already is English; so English speaking computers should just use Base.lproj).

What can be done?I’m not sure I understand completely, but I think you’re missing one point.

As with the base localization, which (as you say) means that Xcode treats it as the “localization” for the development language, and you omit the actual localization for that language (English in your example), the Finder AFAIK uses the “unlocalized” bundle file name as the “base” file name. (Because it’s a bundle, it’s actually a directory name, but the principle is the same.)

If you the developer are on an English system, you can change the “base” file name any time you want, after the app bundle is created, by renaming it in the Finder. I do this all the time for my apps, and the final “base” name is nowhere in my Xcode project settings. Again AFAIK, this has *no* downstream consequences for localized non-English systems — as you’ve seen, the original name is irrelevant when the Finder actually applies localization to the name.

If you want to create the app with the desired English name during archiving, rather than renaming it later, then you must change build settings. AFAIK the one that controls the bundle’s file name is “Product Name”. The default value of this setting is “$(TARGET_NAME)”. If you don’t want the target name, you can put anything you want in there, minus the extension.

So, I assume that if you put the desired English name of your app in the Product Name setting, you’ll get the results you want in all localizations.Here the result of my investigations so far:

1. The file-system-name (shown by ls command) = PRODUCT_NAME.
The PRODUCT_NAME is initially set to $(TARGET_NAME). 
Changing the Target Name to: “New name” changes the Build settings to: PRODUCT_NAME = “New name”.

2. The app-menu and the About Panel show “Bundle name".

3. The Finder shows “Bundle display name" but only if:
3a. Info.plist contains  Bundle display name = $(PRODUCT_NAME)
3b. <current language>.lproj exists, contains InfoPlist.strings and this has CFBundleDisplayName
The Finder does NOT fall back to Base.lproj for current language = development region (as everybody else does).

I fixed my problem by creating a copy of Bundle.lproj/InfoPlist.strings, putting it into an en.lproj folder and adding this in Xcode to the resources of my app.

Sure I could also (as you mentioned) change the PRODUCT_NAME (which has the additional advantage of file-system-name = Finder-name).
But I don’t like the asymmetry of it:
Change the Finder name for development region: change PRODUCT_NAME in Build Settings
Change the Finder name for any other language: change CFBundleDisplayName in xx.lproj/InfoPlist.strings

On the other hand, if the Finder name is the same for all languages, then using the PRODUCT_NAME is clearly better.

Thanks for your help!

One more thing:
Main.strings contains:
/* Class = "NSMenuItem"; title = "AppName"; ObjectID = "1Xt-HY-uBw"; */
"1Xt-HY-uBw.title" = "AppName";

/* Class = "NSMenuItem"; title = "Quit AppName"; ObjectID = "4sb-4s-VLi"; */
“4sb-4s-VLi.title” = “Quit AppName";

I tried to change this to:
"1Xt-HY-uBw.title" = "$(PRODUCT_NAME)";
“4sb-4s-VLi.title” = "Quit $(PRODUCT_NAME)";

But of course the last line does not work. 
Could this work? 
There are quite a few place where the AppName is hardcoded: About, Quit, Help (maybe more).


Kind regards,

Gerriet.
