Access Objective-C property dynamically using the name of the property

Question

I know the string name of a property of an object. How would I go about getting and setting that property using the string?

Answer 1

@synthesize propertyName automates the generation of getter and setter methods.

The compiler generates

• - (id)propertyName;
• - (void)setPropertyName;

If you have a selector as NSString, you can use performSelector:NSSelectorFromString.
e.g.:
[object performSelector:NSSelectorFromString(@"propertyName") ...]
