Hi all. I am a little confused as to when it's best to use: static NSString *AppQuitGracefullyKey = @"AppQuitGracefully"; instead of #define AppQuitGracefullyKey @"AppQuitGracefully" I've seen questions like this for C or C++, and I think what's different here is that this is specifically for Objective C, utilizing an object, a...

This produces an immutable string object: NSString* myStringA = @"A"; //CORRECTED FROM: NSMutableString* myStringA = @"A"; This produces a mutable string object: NSMutableString* myStringB = [NSMutableString stringWithString:@"B"]; But both objects are reported as the same kind of object, "NSCFString": NSLog(@"myStringA is type: ...

In Objective-C i can test wether a given class or instance responds to certain selectors. But how can query a class or instance for all its methods or properties of a class (e.g. a list of all methods or properties)? Wether documented or not, it has to be possible as e.g. WebView can query a plugins scriptable object for all methods and...
