Differences between strong and weak in Objective-C

Question

I\'m new to Obj-C, so my first question is:

What are the differences between strong and weak in @property declarations of poin

Answer 1

Strong: Basically Used With Properties we used to get or send data from/into another classes. Weak: Usually all outlets, connections are of Weak type from Interface.

Nonatomic: Such type of properties are used in conditions when we don't want to share our outlet or object into different simultaneous Threads. In other words, Nonatomic instance make our properties to deal with one thread at a time. Hopefully it helpful for you.
