osx - How To Compare Integer to Objective-C enum -

- (void)updatecheckboxes { nsarray *availablefuncunits = _scanner.availablefunctionalunittypes; for(int = 0; < [availablefuncunits count]; i++) { } }

if set breakpoint within loop, elements of nsarray * 'availablefuncunits' (__nscfnumber *)(int)0 , (__nscfnumber *)(long)3.

the array supposed contain elements of next :

enum { icscannerfunctionalunittypeflatbed = 0, icscannerfunctionalunittypepositivetransparency = 1, icscannerfunctionalunittypenegativetransparency = 2, icscannerfunctionalunittypedocumentfeeder = 3 }; typedef nsuinteger icscannerfunctionalunittype;

shouldn't able following?

if([availablefuncunits objectatindex:i] == icscannerfunctionalunittype.icscannerfunctionalunittypedocumentfeeder) {}

but gives me error saying 'expected identifier or '('.

how can perform comparing correctly? lot help!

there 2 problems see: 1) array availablefuncunits contains nsnumber objects. cant straight compare them primitive types (nsuinteger).

so if should this:

icscannerfunctionalunittype type = [availablefuncunits[i] integervalue] if(type == icscannerfunctionalunittypedocumentfeeder){}

in snippet comparing pointer, not object.

2) error seeing because proper way utilize enums is:

i = icscannerfunctionalunittypedocumentfeeder

Php operator `break` doesn't stop while -

Php operator `break` doesn't stop while - have weird issue, break doesn't break while loop , maintain rotating. logically should break cycle , set output while ($c++ != 5) { // here curl request, doesn't relevant have removed preg_match("!<.*?>(\s*)[^<>]*?{$to}<!", $resp, $result) ; // echo 'cnt = ' .count($result).'<br>'; if(!count($result)) { $amount = 0; echo 'sleep called'; sleep(4); exit; continue; } else { $amount = trim(@$result[1]); $amount = round($amount + $amount * $exchange_ratio, $precision); echo 'break happen<br>'; break; } } so output cnt = 2 break happen cnt = 0 sleep called so skipped break , maintain rotating. how so? edit works fine on localhost issue php version? ...
