objective c - Popover segue from NSCollectionViewItem -


tl;wr

what best way popover-segue cloned view (nscollectionviewitem)?

good afternoon,

i'm trying figure out how segue itemprototype, it's not straight-forward hoping, , has tripped up, somewhat.

i've got nscollectionview, variable number of nscollectionviewitems, each button. hoping i'd need do, segue button small information window, connect window button via popover segue, luck have it, that's not how done.

i'm assuming because button on nscollectionviewitem prototype cloned populate nscollectionview, it's passing mixed messages segue, when it's being called. specifically, i'm receiving following error when press 1 of buttons.

primarily, i'm getting sense of dread. also, don't think likes clones (must on dark side).

i have been looking alternatives creating popover segue via storyboard, looks may not common problem (either that, or i'm still not used relatively small amount of developers os x).

specifically, question is: how "do" popover segue itemprototype? i'm okay doing programatically, haven't written gui-code in objective c before, i'd know segue possible, before try figure out. don't want end pulling hair out, due technical impossibility.

thanks taking time read this! appreciate information can give me, , please let me know if provide more details, make question more clear.

to illustrate i'm asking, bellow 2 images; example of collection view, , example of popover segue i'd apply items in collection view. hope helpful, although can see how might confusing, please let me know if have questions.

collectionview view i'd "popover" of collectionviewitems

edit [2015-05-15 19:08]

the above 2 pictures don't enough explain i'm hoping achieve, following representation of end goal. clarify everything.

storyboards relatively new os x. nscollectionview seems not love apple. there have been numerous reports combination of nscollectionview , storyboards buggy. so, may better off doing non-storyboard way.

it may simplest connect button action method on view controller. in action method, can use sender parameter identify button and, there, collection view item.

you can open pop-over window. instantiate view controller load pop-over content view nib (i.e. [[myviewcontroller alloc] initwithnibname:@"mypopovercontentview" bundle:nil]). you'd set view controller's representedobject. you'd create nspopover , set contentviewcontroller view controller , configure other properties. then, you'd present using -showrelativetorect:ofview:preferrededge:. you'd show relative either sender or 1 of ancestor views within collection view item view.

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.
