Question

ok, this may be a very basic question and I apologise if it is, but its driving me mad and I really need to get a better understanding.

I have an app that I am developing and using a new view controller and xib file for each page.

I call each page by using this code:-

HelpVC = [[[HelpViewController alloc] initWithNibName:@"HelpViewController" bundle: [NSBundle mainBundle]]autorelease];
[self presentModalViewController:HelpVC animated:YES];

Which works great.

However if I have this declared in a file and I then want to call it somewhere else I am getting errors all over the place.

is there any way to initialise all the xib files first in a class file and then call them from that file when needed??

Thanks

This is the error I get back

error: expected specifier-qualifier-list before ‘UserInputViewController’

It seems to cause all of my declarations in the .h file to error with the message above.

Some sample code is:-

.h file

#import <UIKit/UIKit.h>
#import "CgePWViewController.h"
#import "LogBackInViewController.h"
#import "LoginViewController.h"

@interface SettingsViewController : UIViewController
{
    CgePWViewController *cPWVC;
    LogBackInViewController *LBIVC;
    LoginViewController *login;
}

@property(nonatomic, retain) CgePWViewController *cPWVC;
@property(nonatomic, retain) LogBackInViewController *LBIVC;
@property(nonatomic, retain) LoginViewController *login;

so basically as soon as I have added in LoginViewController it causes everything else to error, if I take this out then the app runs perfectly.

Answer 1

Does your LoginViewController.h imports the SettingsViewController as well? It seems to be a “cross reference” (I don’t know if this term makes sense in English as it does in Portuguese).

Before your

@interface SettingsViewController : UIViewController

put a

@class LoginViewController;

and check if it helps.
