ios - Difference between @property and variable within interface declaration -


this question has answer here:

what's difference between putting variable inside of @interface{} declaration in header file, , putting in @property after declaration?

e.g.,

@interface gamecentermanager : nsobject { gkinvite* pendinginvite; } @end

as opposed to

@interface gamecentermanager : nsobject @property (weak, nonatomic) gkinvite* pendinginvite @end

declaring property generates getters , setters instance variable, according criteria within parenthesis.

defining variables in brackets declares them instance variables.

following links provides more info on these.

is there difference between "instance variable" , "property" in objective-c?
