Send object in function & comparison them to coincidence with other objects

Question

I want to send some object to function for check it and set him some data.

For example: i have 4 properties (with int type) of self class (inherit from NSObject class). And i want to change their data in one function. I must send dress of this properties into function, check it to compare with this dresses of this properties: self.opt1, self.opt2, self.opt3, self.opt4, and set them some values.

I try to create function:

- (void)setupMultiplierForObject:(id)object

but i don't know how i can check object argument to comparison self.opt1 (object to object, not their values).

What if must set into if (<here>) {} construction?

Maybe [object isKindOfClass: [self.opt1 class]] is what you want? — Evgeny Karkan, Apr 24 '16 at 19:07
All this objects is equal to one class.. I think it's not be helpful.. I must compare objects id (in my opinion)... — Ivan Trubnikov, Apr 24 '16 at 19:12
Than I guess you should look at isEqual API https://developer.apple.com/library/ios/documentation/General/Conceptual/DevPedia-CocoaCore/ObjectComparison.html — Evgeny Karkan, Apr 24 '16 at 19:17
isEqual compare values of objects, not same object or their id... — Ivan Trubnikov, Apr 24 '16 at 19:20
Look at the example (table) of isEqual - it's check values of objects, not object id. Maybe I can't explain what I want. I will try one more time: If (object is self.opt1) object = 1 elseif (object is self.opt2) object = 2...... — Ivan Trubnikov, Apr 24 '16 at 19:35
Operator == compare values too. I don't need compare values..) I want to check: is sending into function object - is this object (self.opt1 for example). And set to this object (which was referred) new value... — Ivan Trubnikov, Apr 24 '16 at 19:50
Take a look at this thread. You should override isEqual and hash methods in you custom class. http://stackoverflow.com/questions/876866/how-do-i-compare-objects-in-objective-c — Evgeny Karkan, Apr 24 '16 at 21:20

I fix-it with next construction:

[self setupMultiplierForObject:&((*self).time1)];

- (void)setupMultiplierForObject:(int*)object { if (object == &((*self).time1)) { // Doing something with self.time1, because we know that ended object - is self.time1 } }

Send object in function & comparison them to coincidence with other objects
