Obj-C easy method to convert from NSObject with properties to NSDictionary?

Question

I ran across something that I eventually figured out, but think that there\'s probably a much more efficient way to accomplish it.

I had an object (an NSObject which

Answer 1

If the properties had the same names as the keys used to access the dictionary then you could have just used KVC and had valueForKey: instead of objectForKey.

For example given this dictionary

NSDictionary *annotation = [[NSDictionary alloc] initWithObjectsAndKeys:
                             @"A title", @"title", nil];

and this Object

@interface MyAnnotation : NSObject

@property (nonatomic, copy) NSString *title;

@end

it wouldn't matter if I had an instance of the dictionary or MyAnnotation I could call

[annotation valueForKey:@"title"];

Obviously that works the other way as well e.g.

[annotation setValue:@"A title" forKey:@"title"];
