objective c - iOS: How to dynamically change DetailView in SplitView template? -

-

i've got splitview template project. want change detailview on user selecting item in rootviewcontroller.

in fact can't change what's inside view (detailview) it's done in template (when check "use core data storage" on creating project). want switch between whole views.

i've tried that:

appdelegate *appdelegate = [uiapplication sharedapplication].delegate; [appdelegate.detailviewcontroller setview:curretndetailviewcontroller.view]; appdelegate.detailviewcontroller = currentdetailviewcontroller;

by way don't understand why need line#2 (..setview:..)? why assigning detailviewcontroller (line#3) not enough? - code looks awful=(

but anyway doesn't work want. except detailview disappears. i've changed main view, not detailviewcontroller's

i guess should change in splitviewcontroller didn't find out what=(

thanks attention.

i had questions week ago , got little in forum. hope can change you.

first did know apple has multi detail view example? here apple examples

you have understand splitviewcontroller idea of apple doing. think of splitview controller container within device window. container has 2 compartments, thin left hand side bigger right hand side. change on either side have replace compartment compartment of similar size , nature. cannot put in there compartment not fit or fancy cause not fit.

in technical talk find below code in example. splitview controller has array of 2 views , can change views in array. in array 2 views left called navigationcontroller , right detailviewcontroller. if alloc , initiate view , add either of these 2 view replace current view in splitviewcontroller.

nsarray *viewcontrollers = [[nsarray alloc] initwithobjects:self.navigationcontroller, detailviewcontroller, nil]; splitviewcontroller.viewcontrollers = viewcontrollers;

now second part question - think left hand side want able able choose , able change right hand side....am right?

i have read 3 different ways of doing , not seen says 1 better other.

  1. set notification - whereby when click on on left noticiation sent right hand side.
  2. when start bottom or root view of left hand side have reference right hand side, if add subviews etc left hand side pass along reference right hand side.
  3. the way did set protocol in appdelegate or in rootview delegate, on view want talk right hand side uses protocol , right hand side implements protocol. last 1 learnt preferred method of getting modal views talk other views.

i not expert have not added code each of 3 choices above, suggest little bit of googling topics , see examples. if stuck on 1 let me know , try find again google examples have found in past. least complicated think no.1.

i hope going in right direction.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

fortran - Function return type mismatch -

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

queue - mq_receive: message too long -

-
i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
