You need to implement the getter also. Example:

// Interface:

@property (retain) NSObject * someProperty;

// Implementation:

- (void)setSomeProperty:(NSObject *)newValue
{
    @synchronized (self)
    {
        // ...
    }
}

- (NSObject *)someProperty
{
    NSObject *ret = nil;

    @synchronized (self)
    {
        ret = [[someProperty retain] autorelease];
    }

    return ret;
}
