ARC issue in iPhone sdk

i am checking a sample project from github an i got this error,,in one of the class,,there are many classes in it,,but i got door in this class only.the error is "receiver type view controller for instance message does not declare a method with selector 'loadChapter:forBook'

the error came in this method,

- (void)displayBook: (int)theBook andChapter: (int)theChapter andVerse: (int)theVerse
{

    [((PKRootViewController *)self.parentViewController.parentViewController ) showWaitingIndicator];
    PKWait(//here i got this error
           [self loadChapter:theChapter forBook:theBook];
           //[self.tableView reloadData];
           [self reloadTableCache];
           [(PKHistory *)[PKHistory instance] addPassagewithBook:theBook andChapter:theChapter andVerse:theVerse];
           [self notifyChangedHistory];
           ((PKSettings *)[PKSettings instance]).topVerse = theVerse;
           if (theVerse>1)
           {
               [self.tableView scrollToRowAtIndexPath: [NSIndexPath indexPathForRow:theVerse-1 inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:NO];
           }
           else 
           {
               [self.tableView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO];
           }
           UITabBarController *tbc = (UITabBarController *)self.parentViewController.parentViewController;
           tbc.selectedIndex = 0;
           );
}

and also this method have also this error

 - (void)loadChapter: (int)theChapter forBook: (int)theBook
    {
        // clear selectedVerses
        selectedVerses = [[NSMutableDictionary alloc] init];
        PKSettings *theSettings = [PKSettings instance];
        theSettings.currentBook = theBook;
        theSettings.currentChapter = theChapter;
        //[theSettings saveCurrentReference]; -- removed for speed
        [self loadChapter];//here i got the error,,in this case after selector'loadChapter;
    }

The error receiver type view controller for instance message does not declare a method with selector 'loadChapter:forBook' means that the compiler can't found the method loadChapter:forBook: on the interface declaration of self. The same think happens on the other error, but with the method loadChapter. So the problem probably is that you have forgot to declare the methods on the interface, or maybe that you have declare two methods with the same name.

do you have a selector loadChapter without parameters?

aslo check if their declaration is included in interface file or not
