Overriding property accessor names in Objective-C with @synthesize

Question

I'm trying to find documentation on how I can override a property name in Objective-C with @synthesize. If I have an instance variable name of 'foo', I want to write it's accessor as 'bar'.

Doing something such as

@synthesize foo = bar;

gives a compile-time error.

Answer 1

You can but "bar" has to exist first (be a declared variable). From the documentation

You can use the form property=ivar to indicate that a particular instance variable should be used for the property, for example:

@synthesize firstName, lastName, age = yearsOld;

Answer 2

You can change the getter name when you declare the property (getter=bar).

Answer 3

I think you just have it backwards in your @synthesize. What you want is:

@synthesize bar = foo;
