我必须从休息服务 url 中检索图像。但我没有单独的图像 URL（图像的路径）。我在 XML 文件中获取它。我解析了 XML 并将其存储在一个数组中。现在我不明白如何从中检索图像。我的数组如下所示：

   (
    {
    Image = "

        }
        )

我不明白这是来自服务的什么格式（字节数组或base64？）？如何在 tableViewCell 中从中检索图像？

If this is base64 string then You can decode base64 string to NSData using this and you can access UIImage from NSData. 

+ (NSData *)decodeBase64WithString:(NSString *)strBase64;

This format is base64 then you should decode this string into data and get image. Use nsdata+ base64 class and import those class in your project.

Use + (NSData *)decodeBase64WithString:(NSString *)strBase64; method in your code. call like this

 NSData *imageData = [NSData decodeBase64WithString:strBase64];

Edit:

 NSString *yourBase64String = [yourDictionary valueForKey:@"Image"];
 NSData *imageData = [NSData decodeBase64WithString:yourBase64String];
 UIImage * image = [UIImage imageWithData:imageData];

可能是因为对 NSData+Base64 文件进行了修改，但现在的方法是 dataFromBase64String 而不是 decodeBase64WithString
