iphone - Unknown class CPTGraphHostingView in Interface Builder file -


i'm using new core plot version. i'm stuck in error. googled , went through many same question on stackoverflow, didn't find solution. want draw bar chart, have done necessary setting , coding require display bar chart, got stuck in error. have checked cptgraphhostingview on view on xib side. did other linker flag seting , wrote barchartview.hostedgraph = barchart. target memembership option checked. please let me know if i'm missing anything.

provided have setup right core plot header files , core-plot library included in project. here did fix problem.

in target build settings, set linker flags to: 

-objc -force_load "core plot library name"

-all_load not needed if using 4.2+ version.

the reason -force_load -all_load trying compile other libraries had in project.

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...

JAVA - what is the difference between void and boolean methods? -

i new java. writing wrapper-library in java make functions available in basic-like language. i got stock @ point when noted code not executed in java-library although compiler did not complain (using eclipse). resolved replacing code follows: public void videoquality(int vquality) //did not work into public boolean videoquality(int vquality) //works here complete code-snippets: public void videoquality(int vquality) //did not work {if (vquality==16) { vidquality=16; } else if (vquality==-16) { vidquality=-16; } else if (vquality==0) { vidquality=0; } else vidquality=-16; vitamioext.setvideoquality(vidquality); } public boolean videoquality(int vquality) //works {if (vquality==16) { vidquality=16; } else if (vquality==-16) { vidquality=-16; } else if (vquality==0) { vidquality=0; } else vidquality=-16; vitamioext.setvideoquality(vidquality); return true; } i think void corresponds sub in visual basic while boolean corresponds function. i found odd following code worked using...
