objective c - iOS: Methods of ViewController subclass not visible in other classes -

-

i'm trying develop iphone application. things working expect , prefer.

right issue i'm having when adding methods 1 of viewcontrollers methods not visible other parts of applications.

when add same methods, same signature other view controllers visible.

i've googled, browsed stackoverflow, reread, copy/pasted, , prayed spaghetti monster divine insight, no avail.

there must minor detail, in folly overlooking. hope able me!

infopageviewcontroller.h

#import <uikit/uikit.h> #import "db.h"  @interface infopageviewcontroller : uiviewcontroller {     iboutlet uiwebview* wv;     db* db; }  @property (retain, nonatomic) iboutlet uiwebview* wv;  -(void) reloadinfopage; @end

infopageviewcontroller.m

#import "infopageviewcontroller.h" @interface infopageviewcontroller ()  @end    @implementation infopageviewcontroller  @synthesize wv;  - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil {     self = [super initwithnibname:nibnameornil bundle:nibbundleornil];     if (self) {         self.title = nslocalizedstring(@"information", @"information");         self.tabbaritem.image = [uiimage imagenamed:@"tabicon-settings"];         db = [[db alloc] init];          // custom initialization     }      return self; }  - (void)viewdidload {    [super viewdidload];    // additional setup after loading view nib.         dbinfopage* dbip = [db getinfopage];    [wv loadhtmlstring:dbip.html baseurl:nil];    //nslog(@"word%@", dbip.html);    [self reloadinfopage]; }  - (void)viewdidunload {     [super viewdidunload];     // release retained subviews of main view.     // e.g. self.myoutlet = nil; }  - (bool)shouldautorotatetointerfaceorientation:(uiinterfaceorientation)interfaceorientation {     return (interfaceorientation == uiinterfaceorientationportrait); }  -(void)reloadinfopage {     dbinfopage* dbip = [db getinfopage];     [wv loadhtmlstring:dbip.html baseurl:nil];     nslog(@"reloading infopage%@", @""); }  @end

infoviewtest.h

#import <uikit/uikit.h> #import "infopageviewcontroller.h" @interface infoviewtest : nsobject  @end

infoviewtest.m

#import "infoviewtest.h"  @implementation infoviewtest -(void)test {     infopageviewcontroller* ivc = [[infopageviewcontroller alloc] init];     [ivc reloadinfopage]; } @end

this yields error of "no visible @interface 'infopageviewcontroller' declares selector 'reloadinfopage'.

i have tried use autocomplete show me available methods of 'infopageviewcontroller', yields list not containing 'reloadinfopage', instance variable 'wv' not visible outside of scope of class.

i have tried closing , reopening xcode, restart computer. have tried 'clean' project.

any appreciated parts of hair, not yet pulled in frustration.

if have been lacking in providing information, please request , i'll best respond.

actually code correct - have clean project , possibly restart xcode.

but optimize linking/compiling making modifications like:

infoviewtest.h

#import <uikit/uikit.h> //@class infopageviewcontroller;  //add if you'll adding ivar or property of type @interface infoviewtest : nsobject  @end

infoviewtest.m

#import "infoviewtest.h" #import "infopageviewcontroller.h" //here's place import other headers  @implementation infoviewtest -(void)test {     infopageviewcontroller* ivc = [[infopageviewcontroller alloc] init];     [ivc reloadinfopage]; } @end

edit: make sure implementation of db class correct. xcode error might lead wrong assumptions. again: code you've posted seems correct, not optimized compilation.

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
