Question

我试图在视图控制器中使用NSMutableDictionary，在点击图像时将图像和文本加载到详细视图控制器中。我是编程新手，我正在努力理解。有人可以帮忙。

以下是我在视图控制器1 .m

中的代码

- (void) coverflowView:(TKCoverflowView*)coverflowView coverAtIndexWasDoubleTapped:(int)index{



    SomeDetailViewController *detailViewController = [[SomeDetailViewController alloc] initWithNibName:@"SomeDetailViewController" bundle:nil];

        if ((int)index == 0) {
             NSMutableDictionary *myDictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                            @"0002.jpg", @"imagekey",
                            @"This is #1", @"textkey", nil];

        NSLog(@"%@", [myDictionary objectForKey:@"imagekey"]);
        NSLog(@"%@", [myDictionary objectForKey:@"textkey"]);
        }



        [self.navigationController pushViewController:detailViewController animated:YES];
}

当我构建并运行它时，会调用图像键和文本键，但不会显示在详细视图控制器中。我的detailViewController.h

#import <QuartzCore/QuartzCore.h>

@interface SomeDetailViewController : UIViewController < UITextViewDelegate, UINavigationControllerDelegate>{

    IBOutlet UIImageView *imageView;

    IBOutlet UITextView *myText;
    NSString *imagekey;
    NSMutableDictionary *myDictionary;
    NSString *textkey;
}

@property (nonatomic, retain) IBOutlet UIImageView *imageView;
@property (nonatomic, retain) IBOutlet UITextView *myText;
@property (nonatomic, retain) NSString *imagekey;
@property (nonatomic, retain) NSString *textkey;
@property (nonatomic, retain) NSMutableDictionary *myDictionary;
@end

和我的detailViewContoller .m

@synthesize myDictionary;

- (void)viewDidLoad
{
    [super viewDidLoad];

    imageView .image = [[UIImage alloc] init];
    self.imageView.image =[UIImage imageNamed:[(NSMutableDictionary *)myDictionary objectForKey:@"imagekey"]]; 

    self.myText.text =[(NSMutableDictionary *)myDictionary objectForKey:@"textkey"];
}

我知道这与另一篇文章类似，但我建议不要使用NSUsersDefaults，所以我正在尝试这个。

没有错误但没有显示

从视图控制器1 NSDictionary加载图像到detailViewController
