objective c - Iphone Custom Navigation Bar - White Box Error -

-

my problem simple. used method of subclassing navigation bar, , using drawrect attempt draw own custom navigation bar image. however, doesn't draw image... blank white space.

the structure of project tab bar navigation controller under each 1 of it's tabs. each navigation controller has navigation bar , have set bars custom class (customnavbar) in ib.

in customnavbar.h file have:

@interface customnavbar : uinavigationbar { }  @end

in customnavbar.m file have:

#import "customnavbar.h"   @implementation customnavbar  -(void) dealloc{     [super dealloc]; }   - (void)drawrect:(cgrect)rect {     uiimage *image = [uiimage imagenamed:@"navigation_bg.png"];     [image drawinrect:cgrectmake(55, 0, self.frame.size.width, self.frame.size.height)]; }  @end

any ideas why image might not showing , instead getting white background? image in project under resources folder.

thank everyone. :)

when implemented code in test project, did in fact see image. did

[image drawinrect:self.frame];

the image ended covering bottom half of nav bar , top half white (like seeing). perhaps image being drawn low? try playing rect values or set self.frame did , see happens. if still don't see image, make sure nav bar class actual set custom class in interface builder , code being called draw nav bar (maybe put print statement sure).

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...
