我有一個應用程序，你可以在其中有一些東西的細節，然後在那個東西里面你有一個子類別的東西。我做了一個按鈕，因爲沒有足夠的空間放置導航項目，我似乎無法僅調用分配給我的nsmutablearray中的項目。我曾嘗試使用initWithIndexPath:indexPath.row儘管這個錯誤出現：IndexPath.row在按鈕上？
Use of undeclared identifyer "indexPath"; did you mean "NSIndexPath"
這是我的tableView我的tableView裏面的代碼：
#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.
}

}
-(IBAction)add:(id) sender{
[self.tableView reloadData];
[self.tableView setEditing:YES animated:YES];
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) {
for (int i=0; i < patients.count; i++) {

}

[self.tableView setEditing:editing animated:animated];
}
}
