Sandboxing, AppleEvents (or other IAC method)

I have an app that was easy to get into the pre-sandbox App Store and am trying to find a way to get it back in there. There are actually two apps.. A GUI and a Renderer. The GUI controls all the settings, starts and stops the renderer and, while the renderer is running, sends messages to the

FSPathMakeRef deprecated - replacement for LSSetItemAttribute?

FSPathMakeRef is deprecated in 10.8, but LSSetItemAttribute requires an FSRef. Is there a correct way to create an FSRef or perhaps there is a replacement for LSSetItemAttribute to modernize: LSSetItemAttribute(fsRef, kLSRolesAll, kLSItemQuarantineProperties, NULL); Thoughts?

Re: Send msg to object by nameed NSString;

I would think 'copy' would still be ok with this (for example in the case of NSStrings) since that should still be released. For 'assign' I can see the advantage. It’s not just an advantage, it’s avoiding a crasher, most likely, and where it’s not, it’s avoiding silently corrupting an

If I have a class: @interface MyClass : NSObject { NSNumber*myNumber; } @property (nonatomic, retain) NSNumber* myNumber; And in the class implementation I have: -(void)doSomething { // it could get this string from anywhere, not always a constant NSString* myString =

Re: Send msg to object by nameed NSString;

A performance related argument: using property getters and setters in -initWithCoder: and -encodeWithCoder: can bring with them serious performance issues. Might not matter in your case, or in most cases, but it really adds up if you have a large and complex object graph. A recent exercise

Dictionaries or custom class containing no methods?

I need to store a large collection of settings (not application preferences, but parameters describing how complex data is to be displayed) and am looking for pros/cons as to the best way. At the top I have a class called MySettings. Within this I need to have groups of related settings. They can
