objective c - Why am I getting an ARC error with this method? -


this here method im using display items on screen line

cgsize gameareasize = [controller gameareasize];

says receiver type controller2 instance message not declare method selector gameareasize

+(id)ship:(controller2*)controller { cgsize gameareasize = [controller gameareasize]; cgpoint center = cgpointmake(gameareasize.width/2, gameareasize.height/2); items2* item = [[items2 alloc] initat:center withradius:16 andimage:@"viper"]; [item setmovetopoint:center]; [item setspeed:.8]; }

and after use [controller removeactor:item]; remove item off of screen says same thing not being able call removeactor automatic reference counting issue

this not arc issue - controller2 class not implement methods calling on it. – evan mulawski jul 7 '12 @ 1:09
    
@evan: relate arc. arc makes "undeclared selector" compile-time warnings errors -- needs see method signature in order know return value: stackoverflow.com/questions/9245317/… – josh caswell jul 7 '12 @ 7:55
    
possible duplicate of compiler warnings methods not found or not declared – josh caswell jul 7 '12 @ 7:55
    
@joshcaswell: arc may treat undeclared selector warnings errors, still undeclared selectors, means problem class not declare them. – evan mulawski jul 7 '12 @ 16:07
    
@evan: if implemented not declared (or compiler can't see declaration @ point), , arc turned off, code compile , run , question wouldn't exist. – josh caswell jul 7 '12 @ 17:18

c++ - Accessing inactive union member and undefined behavior? -

i under impression accessing union member other last 1 set ub, can't seem find solid reference (other answers claiming it's ub without support standard). so, undefined behavior? the confusion c explicitly permits type-punning through union, whereas c++ ( c++11 ) has no such permission. c11 6.5.2.3 structure , union members 95) if member used read contents of union object not same member last used store value in object, appropriate part of object representation of value reinterpreted object representation in new type described in 6.2.6 (a process called ‘‘type punning’’). might trap representation. the situation c++: c++11 9.5 unions [class.union] in union, @ 1 of non-static data members can active @ time, is, value of @ 1 of non-static data members can stored in union @ time. c++ later has language permitting use of unions containing struct s common initial sequences; doesn't permit type-punning. to determine whether union type-punning is allowe...

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.
