blocks|key|4314295|text|这对我很有帮助：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4314296|首先创建此函数，以帮助拉下图像。如果您正在提取多个图像，您可能想要创建一个新的swift文件并将其设置为静态的，或者只是在您需要它的文件中调用它。这样你就可以引用它而不是重写代码：|4314297|static+func+loadImage(_+imageView:+UIImageView,_+urlString:+String)+{

This helped me:

Create this function first to help pull down the image. If you're pulling multiple images, you may want to create a new swift file and make this static or just call it in the file that you need it. This way you can refer to it instead of re-writing code:

<pre><code>static func loadImage(_ imageView: UIImageView,_ urlString: String) {
 let imgURL: URL = URL(string: urlString)!
 URLSession.shared.dataTask(with: imgURL) { (data, respond, error) in
 guard let data = data, error == nil else { return}

 DispatchQueue.main.async (execute: {
 imageView.image = UIImage(data: data) 
 })
 }.resume()
}
</code></pre>

Then to pull down the info:

<pre><code>if let logoName = variable.logo {
 StaticFileName.loadImage(cell.imgVariableInCell, "\(logoName)")
 }
 return cell
}
</code></pre>

Then you're good to go.

You can use SDWebImage 

First You need to Import this 

<pre><code>import SDWebImage
</code></pre>

Then You may use this method 

<pre><code>let imgUrl = URL(string:"your image URL string")
cell.imageView?.sd_setImage(with: imgUrl, placeholderImage: UIImage(named: "propic"))
</code></pre>

blocks|key|4314466|text|当然，您的图像不会显示给您。因为当Alamofire开始下载你的图像时，它会在后台线程中进行处理。但你是在主线程或UI线程中工作，所以你需要从后台切换到主线程，这将为你工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4314467|Alamofire.request("http://xxxxxxx.com/uploads/"+%2B+(self.array[indexPath.row]["cover"]+as!+String)).responseImage+{+response+in

}|code-block|syntax|javascript|4314468|如果你认为这对你来说很难做到这一点，我建议你使用这个叫做Kingfisher的库，它将为你处理异步加载图像，使你的单元格的表顺利运行。|4314469|链接：https://github.com/onevcat/Kingfisher|offset|length|4314470|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/onevcat/Kingfisher^0|0|0|0|3|11|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|X|8|@]|9|@$K|Y|L|Z|1|10]]|A|$]]|$1|M|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|N|$O|$5|P|Q|R|A|$S|T]]]]

Of course your image will not show for you. Cause when Alamofire starts downloading your image its process in background thread. But you are working in Main Thread or UI Thread so you need to swap from background to Main Thread it will work for you. 

<pre><code>Alamofire.request("http://xxxxxxx.com/uploads/" + (self.array[indexPath.row]["cover"] as! String)).responseImage { response in
 DispatchQueue.main.async {
 if let image = response.result.value {
 cell.imageView?.image = image
 }
 }
}
</code></pre>

If you think it is difficulty for you to do this i recommend you to use this library called Kingfisher it will handle asynchronous loading images for you that make your cell's table run in smoothly.

blocks|key|4314375|text|您的代码是正确的。我认为传输安全屏蔽了你在http上的图像。将此代码添加到info.plist文件中|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4314376|<key>NSAppTransportSecurity</key>

your code is correct. 
i think the transport security block your image over http . 
add this into your info.plist file 

<pre><code>&lt;key&gt;NSAppTransportSecurity&lt;/key&gt;
&lt;dict&gt;
 &lt;key&gt;NSAllowsArbitraryLoads&lt;/key&gt;
 &lt;true/&gt;
 &lt;key&gt;NSExceptionDomains&lt;/key&gt;
 &lt;dict&gt;
 &lt;key&gt;example.com&lt;/key&gt; //put your domain name here
 &lt;dict&gt;
 &lt;key&gt;NSExceptionAllowsInsecureHTTPLoads&lt;/key&gt;
 &lt;true/&gt;
 &lt;key&gt;NSIncludesSubdomains&lt;/key&gt;
 &lt;true/&gt;
 &lt;/dict&gt;
 &lt;/dict&gt;
&lt;/dict&gt;
</code></pre>

and you can also use the alamofire's image library. just add pod alamofireImage.

blocks|key|4314573|text|您应该将链接作为变量传递给单元格中的变量，并覆盖UITableViewCell中的awakefromnib函数。在alamofire+nib中，调用awakeFrom请求将图像加载到单元格中，这样就不会在每次查询重用单元格时都调用它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4314574|所以|4314575|//CellCode|4314576|import+Alamofire

You should pass the link as a variable to a variable in the cell and override the awakefromnib function in UITableViewCell. Inside the awakeFrom nib you call the alamofire request to load the image in the cell, with this way you will not call the query every time it reuses the cell.

so 

//CellCode 

<pre><code>import Alamofire
...

 var imageLink:String?

 override func awakeFromNib() {
 super.awakeFromNib()
 Alamofire.request(imageLink).responseImage { response in
 if let image = response.result.value {
 self.imageView?.image = image
 }
 }
 }


//cell configuration
cell.imageLink = "http://xxxxxxx.com/uploads/" + self.array[indexPath.row]["cover"] as! String)
</code></pre>

I am using AlamofireImages to try to download an image from a server and display it in my table view cell, this is what I got, but my images does not appear, just the textLabel and detailTextLabel

<pre><code>override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -&gt; UITableViewCell {

 let cell = tableView.dequeueReusableCell(withIdentifier: "trendingCell", for: indexPath)

 print(self.array[indexPath.row])

 cell.textLabel?.text = (self.array[indexPath.row]["title"] as! String)

 cell.detailTextLabel?.text = (self.array[indexPath.row]["username"] as! String)

 Alamofire.request("http://xxxxxxx.com/uploads/" + (self.array[indexPath.row]["cover"] as! String)).responseImage { response in
 if let image = response.result.value {
 cell.imageView?.image = image
 }
 }

 return cell
 }
