在一个按钮上的IndexPath.row？

Question

I have an app in which you can have some details of something and then inside that thing you have a sub-category of things. I have made a button as there was not enough room for a navigation item and I can't seem to be able to call only the items that are assigned to that in my nsmutablearray. I have tried to used initWithIndexPath:indexPath.row though it comes up with this error:

Use of undeclared identifyer "indexPath"; did you mean "NSIndexPath"

This is the code for my tableView inside my tableView:

#import "PRViewController.h"

#import "Patient.h"

#import "LSAppDelegate.h"

#import "LSViewController.h"

#import "LSAppDelegate.h"

#import "Patient.h"

#import "PatientController.h"

#import "AddPatientController.h"

#import "treatmentController.h"

@interface PRViewController ()

@end

@implementation PRViewController

{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.navigationItem.rightBarButtonItem = self.editButtonItem;
    self.title = @"Treatments";
    LSAppDelegate *delegate = (LSAppDelegate *)[[UIApplication sharedApplication] delegate];
    patients = delegate.patients;
    [[UIToolbar appearance] setTintColor:[UIColor brownColor]];
    // Do any additional setup after loading the view, typically from a nib.

    if(self.tableView) {
        NSMutableArray *indices = [[NSMutableArray alloc] init];
        for (int i=0; i < patients.count; i++) {
            [indices addObject:[NSIndexPath indexPathForRow:i inSection:0]];

        }
        NSArray *lastIndex = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:patients.count inSection:0]];
        if (self.tableView) {

Answer 1

Use of undeclared identifyer "indexPath"; did you mean "NSIndexPath"

This error only happen if your do not declare indexPath but try to use it. As Xcode compiler's code sense detect and show you hint that it may be NSIndexPath instead of indexPath. check the use and declaration of indexPath.

Answer 2

- (IBAction)PatientRecords:(id)sender {
    PRViewController *AddPatient = [[PRViewController alloc] initWithIndexPath:indexPath.row];
    [self.navigationController pushViewController:AddPatient animated:YES];
}

This code looks to be the culprit, you're not declaring the variable indexPath anywhere, you need to use index rather than indexpath from what I can see.
