认为不能正常工作，因为我也想要它

Question

我对应用程序开发场景非常陌生，并尝试使用互联网上的信息以及几周前我做过的“短期课程”。

我正试图将信息从我的视图控制器转移到辅助控制器。在第一个视图控制器中，用户输入一个代码，它会查找plist并显示3个代码。

我将提供我的代码，非常感谢任何帮助：

我有3个控制器。

导航控制器

查看Controller.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@property (strong, nonatomic) IBOutlet UITextField *codeTextField;


@end

查看Controller.m

    #import "ViewController.h"

    #import "ViewController.h"
    #import "DetailViewController.h"

    @interface ViewController ()
    @property (strong, nonatomic) NSArray *ID;
    @end

    @implementation GBRFViewController

    #pragma mark View lifecycle
    - (void)viewDidLoad
    {
        [super viewDidLoad];

        // Automatically present the keyboard when this screen is first displayed
        [self.headcodeTextField becomeFirstResponder];

        NSString *dataFilePath = [[NSBundle mainBundle] pathForResource:@"ID" ofType:@"plist"];
        self.ID = [NSArray arrayWithContentsOfFile:dataFilePath];
    }


    #pragma mark Scene management
    - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
    {
        // Move the search term across into the results view controller as it is presented
        GBRFDetailViewController *controller = segue.destinationViewController;
        controller.searchTerm = self.headcodeTextField.text;
    }

    #pragma mark Text field delegate
    - (BOOL)textFieldShouldReturn:(UITextField *)textField
    {
        // Kick off the segue manually when the return key is tapped
        [self performSegueWithIdentifier:@"searchSegue" sender:self];
        return YES;
    }


    @end

DetailViewController.h

#import <UIKit/UIKit.h>

@interface GBRFDetailViewController : UIViewController

@property (strong, nonatomic) NSDictionary *IDDetail;
@property (strong, nonatomic) NSString *searchTerm;

@end

DetailViewController.m

#import "DetailViewController.h"

@interface DetailViewController ()
@property (strong, nonatomic) UIPopoverController *masterPopoverController;
@property (strong, nonatomic) IBOutlet UILabel *titleLabel;
@property (strong, nonatomic) IBOutlet UILabel *code1Label;
@property (strong, nonatomic) IBOutlet UILabel *code2Label;
@property (strong, nonatomic) IBOutlet UILabel *code3Label;

@end

@implementation DetailViewController


#pragma mark View lifecycle
- (void)viewDidLoad
{
    [super viewDidLoad];

    // Setting the title on the view controller will automatically update the navigation bar title
    self.title = self.searchTerm;

    // Only set the outlets up if the book detail is set
    if (self.IDDetail)
        [self configureView];
}

- (void)configureView
{
    // The title of the view controller is displayed in the navigation bar
    self.title = self.IDDetail[@"Title"];

    // Take the data out of the dictionary and populate the outlets
    self.titleLabel.text = self.IDDetail[@"ID"];
    self.code1Label.text = self.IDDetail[@"Code1"];
    self.code2Label.text = self.IDDetail[@"Code2"];
    self.code3Label.text = self.IDDetail[@"Code3"];
}

#pragma mark Property overrides
- (void)setIDDetail:(NSDictionary *)IDDetail
{
    if (_IDDetail != IDDetail) {
        _IDDetail = IDDetail;
        [self configureView];
    }
}

#pragma mark Split view controller
- (void)splitViewController:(UISplitViewController *)splitViewController willHideViewController:(UIViewController *)viewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)popoverController
{
    [self.navigationItem setLeftBarButtonItem:barButtonItem animated:YES];
    self.masterPopoverController = popoverController;
    barButtonItem.title = @"IDs";
}

- (void)splitViewController:(UISplitViewController *)splitViewController willShowViewController:(UIViewController *)viewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem
{
    [self.navigationItem setLeftBarButtonItem:nil animated:YES];
    self.masterPopoverController = nil;
}

@end

我的Plist采用以下格式（虽然有超过25000行）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>ID</key>
    <string>0A00</string>
    <key>M=0</key>
    <string>0</string>
    <key>M=1</key>
    <string>1533</string>
    <key>M=2</key>
    <string>3066</string>
</dict>
</plist>
