UIImage沒有顯示

我使用AFNetworking解析JSON。UIImage沒有顯示

我從一個視圖傳遞2個圖像和文本到另一個，但我不能在UIImage視圖上查看圖像。

我可以在控制檯上看到圖像的鏈接。

#import "KKDetailsViewController.h" 


@interface KKDetailsViewController() 

@end 

@implementation KKDetailsViewController 

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

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    self.textView.text = [self.importVideoMetaData objectForKey:@"description"]; 

    self.imageView.image = [[UIImage alloc] init]; 
    self.imageView.image = [UIImage imageNamed:[(NSDictionary *)self.importThumbnail objectForKey:@"hqDefault"]]; 


    NSLog(@" imported thumbnail %@", self.importThumbnail); 


}

這裏是.h文件

#import <UIKit/UIKit.h> 

@interface KKDetailsViewController : UIViewController 

@property (weak, nonatomic) NSDictionary *importVideoMetaData; 

@property (weak, nonatomic) NSDictionary *importThumbnail; 

@property (weak, nonatomic) IBOutlet UITextView *textView; 

@property (weak, nonatomic) IBOutlet UIImageView *imageView; 
@end

哪裏是'importVideoMetaData'設置？ – trojanfoe 2013-02-08 12:19:26

self.importVideoMetaData你如何給這個對象數據，你可以發佈一些代碼。 – Rahul 2013-02-08 12:21:37

'imageNamed：'將會返回一個可用於你的目標的圖像，你不能簡單地通過一個網址，並期望它的工作... – Alladinian 2013-02-08 12:21:58

確定這裏是我如何使它工作：

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 

    self.textView.text = [self.importVideoMetaData objectForKey:@"description"]; 

    NSURL *url = [[NSURL alloc] initWithString:[self.importThumbnail objectForKey:@"hqDefault"]]; 

    [self.imageView setImageWithURL:url placeholderImage:[UIImage imageNamed:@"fakeThumbnail.png"]]; 


    NSLog(@" imported thumbnail %@", url); 


}
