Question

我有一个应用程序，你可以在其中获得某些东西的细节，然后在那个东西里面你有一个子类别的东西。我已经创建了一个按钮，因为没有足够的空间来存储导航项目，我似乎无法仅调用在我的nsmutablearray中分配给它的项目。我尝试使用initWithIndexPath:indexPath.row虽然它出现了这个错误：

使用未声明的标识符“indexPath”;你的意思是“NSIndexPath”

这是我的tableView中的tableView的代码：

#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

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    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.
}

{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(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++) {
                UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:[indices objectAtIndex:i]];
                [cell setSelectionStyle:UITableViewCellSelectionStyleBlue];
            }
        }
    }
    [self.tableView setEditing:NO animated:YES];
    treatmentController *AddPatient = [[treatmentController alloc] init];
    [self.navigationController pushViewController:AddPatient animated:YES];
    [super setEditing:NO animated:NO];
}

-(void)setEditing:(BOOL)editing animated:(BOOL) animated {
    if ( editing != self.editing ) {
        [super setEditing:editing animated:animated];
        [self.tableView setEditing:editing animated:animated];

    }
}

#pragma mark UITableViewDataSource Methods

- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tv dequeueReusableCellWithIdentifier:@"cell"];
    if ( nil == cell ) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"];
    }

    NSLog(@"indexPath.row = %d, patients.count = %d", indexPath.row, patients.count);
    Patient *thisPatient = [patients objectAtIndex:indexPath.row];
    if (thisPatient.treatmentName.length > 0) {
        cell.textLabel.text = thisPatient.treatmentName;
        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
        cell.textLabel.textColor = [UIColor blackColor];
    } else {

    }
    if (self.editing) {
        [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
    }
    return cell;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [patients count];
}

#pragma mark UITableViewDelegate Methods

- (void) tableView:(UITableView *)tv commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if ( editingStyle == UITableViewCellEditingStyleDelete ) {
        [patients removeObjectAtIndex:indexPath.row];
        [tv deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft];
    }
}

- (void)tableView:(UITableView *)tv didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    PatientController *patient = [[PatientController alloc] initWithIndexPath:indexPath];
    [delegate.navController pushViewController:patient animated:YES];
    [tv deselectRowAtIndexPath:indexPath animated:YES];

Answer 1

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

如果您没有声明indexPath但尝试使用它，则只会发生此错误。由于Xcode编译器的代码检测检测并显示它可能是NSIndexPath而不是indexPath。检查indexPath的使用和声明。

Answer 2

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

这段代码看起来是罪魁祸首，你不是在任何地方声明变量indexPath，你需要使用index而不是indexpath。

IndexPath.row在按钮上？
