Objective-C Compiler Directives
@dynamic
"You use the @dynamic keyword to tell the compiler that you will fulfill the API contract implied by a property
either by providing method implementations directly or at runtime using other mechanisms such as dynamic
loading of code or dynamic method resolution. " R[0]p61
"@dynamic just tells the compiler that the getter and setter methods are implemented not by the class itself
but somewhere else (like the superclass or will be provided at runtime)." Ref[4]
"Tells the compiler the setter and getter methods for the given (comma separated) properties are implemented manually,
or dynamically at runtime. Accessing a dynamic property will not generate a compiler warning, even if the getter/setter
is not implemented. You will want to use @dynamic in cases where property getter and setter methods perform custom code.
@end – Marks end of class implementation." Ref[8]
@synthesize
"Generate setter and getter methods for a comma separated property list according to property modifiers.
If instance variable is not named exactly like @property, you can specify instance variable name after the equals sign." Ref[8]
