I've just "modernized" a bunch of cross-platform code in Xcode 4.4, to use the new Obj-C literal and collection-access syntax. Works great when built for Mac OS. But now I discover that the code gets tons of compile errors on iOS because in the 5.1 SDK the NSArray and NSDictionary classes don't declare the -objectForKeyedSubscript: or -objectForIndexedSubscript: methods.
Presumably this will be remedied in the hypothetical future release of Xcode that includes the iOS 6 SDK. But is there anything I can do until then to make this build and run on iOS 5.1? (And does this also imply that code using array/dictionary subscripting won't run on OS X 10.7?) My first thought was to declare some categories on NSArray and NSDictionary to define those methods, but that's likely to cause issues when iOS 6 comes out and already includes those methods — I'll get compile errors (which I can work around with #ifdefs) but also a warning at launch time because the methods are declared in two places. (Note that I'm _not_ asking anything about NDA'd beta software; I'm only asking how to make the compiler feature already available in Xcode 4.4 work on the already-available iOS 5.1.) —Jens _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
