Question

Is it possible like following inverse direction?

[Normally direction of property]

@interface MainClass {
  CustomClass *test1;
 }
 @end

 @implementation MainClass
  self.test1 = [[CustomClass alloc] init];
 @end

[Wondering about inverse directrion of property]

Is it possible to indicate from test1 to self?

ex) like test1.myowner? or test1<-self? or test1/self or etc..

Answer 1

No, not really. You can’t relate from the object that is set to the object of which the proprty is set. You’ll almost certainly want to declare a property on CustomClass also, then in the setter of MainClass, set the property of the instance of CustomClass to self.
