iOS Objective-C Controlling Button Images -


i have button. unsure if uibutton class type. button dragged object library main.storyboard.

i don't have text, instead have image. , plan use 2 images. 1 "loop on" , other "loop off". i'm playing sound , button controls whether or not loop sound. i'm set understanding how looping versus not.

i have set "loop off" image default image under attributes inspector.

so when button gets touched, i'll change behavior of playing sound "loop forever" , i'd change image of button within ibaction function.

i can set title button in attributes inspector.

but don't see title resource name (auto-typing-complete) within viewcontroller.m code.

i know there properties per state images. believe there's "setimage" action uibutton.

what can't determine how button named in code because button added via dragging out of object library.

anyone have knowledge of these resources named, reference file?

a search found close, following link:

http://ranga-iphone-developer.blogspot.com/2011/08/how-to-change-uibutton-image.html

however solution doesn't appear reference particular button name, title, or id; unless text "button" supposed replaced specific resource name.

have added iboutlet uibutton in code. if not see link

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.
