ios - Unwind to specific instance of ViewController -


i have viewcontroller i'm re-instantiating navigate instance of (there's reason this) following code:

let viewcontroller = storyboard.instantiateviewcontrollerwithidentifier("completionviewcontroller") as! completionviewcontroller self.navigationcontroller?.pushviewcontroller(viewcontroller, animated: true)

everything works fine, except when try unwind... since every instance of control has unwind method:

@ibaction func unwindtothisviewcontroller(segue: uistoryboardsegue) {}

it ends unwinding last instance of vc instead of first (which want), example:

vc1 > vc2 > vc3 > unwind here

i want unwind "vc1", unwinds "vc3".

is there anyway can unwind first instance of vc; or in example "vc1"?

in completionviewcontroller, there 3 icons @ top of view. if ctrl drag left yellow icon right red 1 (the "exit") can choose unwinding segues. can use unwind in code ;)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
