macOS Accessing CFBundleTypeExtensions Array in Program?

[MorphingDragon]

I can't figure out the code to get this to work. I want to retrieve the supported extensions array from info.plist.

[[[[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleDocumentTypes"] objectAtIndex:0] objectForInfoDictionaryKey:@"CFBundleTypeExtensions"];

objectForInfoDictionaryKey is only available for NSBundle, so you should have gotten an error with the 2nd use of it. Did you check to see what object is being returned from objectAtIndex ?

It'd help to post: any errors, what you're expecting, what you're seeing.

What error or warning messages are you getting, if any? I can guess, but it's better if you tell us.

Also note that objectForInfoDictionaryKey: is an NSBundle message. It returns an NSArray (typed as id), which you are correctly using objectAtIndex on. Thereafter, you are incorrectly using objectForInfoDictionaryKey (an NSBundle message, remember), when I think you want objectForKey (an NSDictionary message). Too much copy-pasta?


BTW, I think this is invalid Objective-C syntax in your sig:

[myCake tasty] = YES;

Changed it to objectForKey, works fine now.

Thanks.

Oddly enough, it didn't error, or even a warning.

Man, now you made me want lunch.
