Difference between @interface declaration and @property declaration

Question

I\'m new to C, new to objective C. For an iPhone subclass, Im declaring variables I want to be visible to all methods in a class into the @interface class definition eg

Answer 1

@interface declares the instances variables of a class in obj-c. You need it to create an instance variable. However the variable is not visible outside the class by default (as the field is by default protected).

@property tells the compiler to specify a particular property accessor (get/set) method. However, you will need to use @synthesize to actually have the compiler generate the simple accessors automatically, otherwise you are expected to create them on your own.
