ios - Swift Messaging App - Conversation UIScrollView Alignment -


i building messaging app using swift , parse.com.

i have been making progress, having trouble getting message bubbles align correctly in uiscrollview.

when begin conversation, message aligns bottom of scroller.

however, touch uiscrollview, message(s) pop top of frame.

i think understand why - recent message should align bottom when entire conversation longer scroller. but, when conversation shorter frame, should align top (like in imessage etc.).

i don't know how behave this.

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.
