Dynamic object property name in objective C

Question

I'm trying to access a property of an object using a dynamic name... is this possible?

like in javascript:

var foo = 'bar';
appr.templates[foo];

the idea is to access appr.templates.bar

Answer 1

You can use valueForKey: for this purpose.

Like this:

NSString *foo = @"bar";

[appr.templates valueForKey: foo]

Answer 2

You can do that using Key-Value Coding or KVC, see the method -valueForKeyPath: . For example:

@interface Foo
@property(strong) NSString *bar;
@end

// Somewhere in other code, foo is an instance of Foo
NSString *bar = [foo valueForKeyPath:@"bar"];
