Ios 如何使用NSdictionary填充数据？

如何将数据发送到另一个详图视图控制器中的表视图？在我的第一张桌子上，我没有得到预期的输出。现在我需要用具有属性detailContent的数据填充第二个表。这是我的密码

#import <UIKit/UIKit.h>

@interface RecipeBookViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> 

@property (nonatomic, strong) IBOutlet UITableView *tableView;

@end``

\详细视图：

@interface RecipeDetailViewController : UIViewController

@property (nonatomic, strong) IBOutlet UILabel *recipeLabel;
@property (nonatomic, strong) NSString *recipeName;
@property (nonatomic , strong)NSString *recipeTable ;
@property (nonatomic , strong) IBOutlet UITableView *detailContent ;


@end

在实施时：

#import "RecipeBookViewController.h"
#import "RecipeDetailViewController.h"

@interface RecipeBookViewController ()

@end

@implementation RecipeBookViewController {
    NSArray *recipes;
}

@synthesize tableView;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Initialize table data
    recipes = [NSArray arrayWithObjects:@"Veg", @"Non Veg", @"Beverages", nil];
}


- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

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

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"RecipeCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }

    cell.textLabel.text = [recipes objectAtIndex:indexPath.row];
    return cell;
}


- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"showRecipeDetail"]) {
        NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
        RecipeDetailViewController *destViewController = segue.destinationViewController;
        destViewController.recipeName = [recipes objectAtIndex:indexPath.row];
        destViewController.detailContent = [recipes objectAtIndex:indexPath.row];
    }
}


@end

#import "RecipeDetailViewController.h"

@interface RecipeDetailViewController ()

@end

@implementation RecipeDetailViewController

@synthesize recipeLabel;
@synthesize recipeName;

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

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Set the Label text with the selected recipe
    recipeLabel.text = recipeName; 
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

@end

要填充下一个tableView，需要实现UITableView委托和协议方法 在RecipedDetailViewController中
实施：

@interface RecipeDetailViewController () <UItableViewDataSource, UITableViewDelegate>

@end

@implementation RecipeDetailViewController

@synthesize recipeLabel;
@synthesize recipeName;

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

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Set the Label text with the selected recipe
    recipeLabel.text = recipeName;




}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

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

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"RecipeCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }

    cell.textLabel.text = [recipes objectAtIndex:indexPath.row];
    return cell;
}

@结束

返回RecipeBookViewController.m

in PrepareForSegue 

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"showRecipeDetail"]) {
        NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
        RecipeDetailViewController *destViewController = segue.destinationViewController;
        destViewController.recipe = recipe;
    }
}

费萨尔，到底是什么问题？您是否能够按下viewController，或者您在下一个视图中看不到数据的问题？先生，我想填充第二个表。若我在第一个表中单击了veg，那个么我应该会在详细视图表中看到veg列表，如（chappathi、rotti等）。如果（鸡、羊肉等）是那样的话。我不知道在哪里和如何申报这个。你能帮忙吗？请……这对我作为新生会更有帮助。所以，现在你在下一个viewController上看不到蔬菜了，对吗？如果答案是肯定的，那么您是否检查了出口？destViewController.recipeName=[recipes objectAtIndex:indexPath.row]；destViewController.detailContent=[recipes objectAtIndex:indexPath.row]；->将同一字符串两次传递给第二个VC。一本不应该是详细的词典吗？我在任何地方都看不到NSDictionary…@Basheer_CAD:我在第二个控制器中看到了veg标签，我在第二个表中也有一个表视图。现在我想使用NSDictionary在表中填充veg、NOVEG和饮料数据！谢谢你的帮助，先生。现在我需要在单击veg时填充chappathi、rotti等数据。在点击其他类似的项目时。。先生，我有一个“vegDict=[[NSMutableDictionary alloc]initWithObjectsAndKeys:@“Rotti”，“Chappathi”，nil]在详细视图中；“现在我如何传递这些数据？”？同样在我的CelforRowatineXpath中，我有“cell.textLabel.text=[vegDict objectForKey:vegDict]；”请解释如何将vegDict传递到第二个表IR，我有同一个表的更新代码。你能帮我查一下产量吗？
