Objective-C and Dot Notation
</pre>
A key point to understand about dot notation is that it only works for instance variables for which synthesized accessor methods have been declared. If you attempt to use dot notation to access an instance variable for which no synthesized accessor is available the code will fail to compile.with an error similar to: <tt>error: request for member 'accountBalance' in something not a structure or union</tt>
