After the implementation begins, we must synthesize the accessor for the properties we declared in our interface file and implement the declared methods: #import "HelloWorldViewController. The intent of this concept is to filter out some obviously non-object types while leaving a hook for later tightening if a means of exhaustively marking CF types is made available. Second, it makes it much less likely that the user will see confusing aliasing problems due to the implementation, below, where their store to the writeback temporary is not immediately seen in the original argument variable. P. This is all admittedly convoluted. For all other objects, the lvalue is loaded with primitive semantics. While the interface is described as an explicit hierarchy of pools, the rules allow the implementation to just keep a stack of objects, using the stack depth as the opaque pool handle.
