• Ok to implement backend/shared functionality for iPhone in JavaScript?

  - by John Wright

  Is it ok to use the Webkit Javascript engine to implement cross-platform, non-GUI backend functionality on the iPhone, iPad? In my case, I was interested in re-using Javascript code that I have that works on top of SQLite. I thought I would need to re-implement the logic in Obj-C but perhaps I could just share it and expose some hooks into Obj-C using JSCocoa or straight through JavaScript core. Is this legal per Apple guidelines?

  The Apple documentation says that the sender passed to the NSMenuItem's action can be set to some custom object, but I can't seem to figure out how to do this. Is there a method I'm not seeing someplace in the documentation?

• How to enable the video output on your iPad app?

  - by Sjakelien

  Just found out that the video output of the iPad is not a system level functionality, but that it needs to be explicitly build in into each app. Is there somebody who has any experience with this, who could point me to sample code? Secondary question would be: why wouldn't Apple make this a system feature. Is it a hardware issue, that I should be aware of when building this into my app?

• Historical reason behind different line ending at different platforms

  - by Imran

  Why did DOS/Windows and Mac decide to use \r\n and \r for line ending instead of \n? Was it just a result of trying to be "different" from Unix? And now that Mac OS X is Unix (-like), did Apple switch to \n from \r?

• Is there a way to get a mobile Safari WebApp to "forget" its state?

  - by Alex Mcp

  I have a nascent bridge scoring app that is meant to be stored locally on an iPod touch/iPhone (iPad? Would probably be fugly...) So far so good, got a custom icon rolling and basic JS navigation laid out, but my problem is that it retains its state when I quit the app. Is there a simple magic Apple meta tag for this? Or is it achieved with javascript? Thanks for any insight.

• Are protocols inheritable in Objective-C?

  - by aquaibm

  I saw this in some header file in the framework directory: @interface NSCharacterSet : NSObject <NSCopying, NSMutableCopying, NSCoding> @end @interface NSMutableCharacterSet : NSCharacterSet <NSCopying, NSMutableCopying> @end I thought protocols were inheritable.If I am right about that,There is no need to type <NSCopying, NSMutableCopying> again after "NSMutableCharacterSet : NSCharacterSet".And NSMutableCharacterSet also conforms to NSCoding protocol, right? Than why is Apple typing that again?Am I making mistake?

• IBOutlet on properties and exposition of the class

  - by Espuz

  Apple, for memory management issues, recommend defining outlets on properties, not in the attribute declaration. But, as far as I know, declaring properties exposes the class to external classes, so this could be dangerous. On UIViewController we have the main view definition and the logic, so MVC is slightly cheated in this cases. What is the beteer approach, Apples's recommendation for memory-management or armored classes?

• Which Cross Platform Preprocessor Defines? (__WIN32__ or __WIN32 or WIN32 )?

  - by brubelsabs

  I often see __WIN32, WIN32 or __WIN32__. I assume that this depends on the used preprocessor (either one from visual studio, or gcc etc). Do I now have to check first for os and then for the used compiler? We are using here G++ 4.4.x, Visual Studio 2008 and Xcode (which I assume is a gcc again) and ATM we are using just __WIN32__, __APPLE__ and __LINUX__.

• AppleScript Editor, write message to the "Result" window

  - by Patrick

  I am using the Mac OS X Apple Script Editor and (while debugging) instead of writing a lot of display dialog statements, I'd like to write the results of some calculation in the window below, called "Result" (I have the German UI here, so the translation is a guess). So is there a write/print statement that I can use for putting messages in the "standard out" window? I am not asking to put the messages in a logfile on the file system, it is purely temporary.

• Cocoa Scripting Bridge and <contents> element

  - by Stephen

  So, the application I'm trying to script has a scripting definition file that includes a <contents> element, which is an "implicitly specified container." The question, how do I get at what's inside this element using Scripting Bridge? Or alternatively, how do I send the Apple Event necessary to retrieve it and then transform what I get back into an SBObject? I already tried: [document nameOfKey] document.nameofKey [document contents] document.contents
