Question

以下是我从API获取的示例JSON数据。我想使用swift在tableviewcell中显示"ArticleTitle"和"ImageURL"。

"ArticleTitles":[{"ArticleID":"872",
 "ArticleTitle":"IS 'NOTHlNGNESS' AN EXPERIENCE ?",  
 "Author":"Asampoorna",
 "ImageURL":"http://motherofall.org/sites/default/files/blog/Ignorance.png"
},{..........}]

Answer 1

在响应中，您将获得结果数组。然后在你尝试使用数组的东西之后，这是错误的。获得结果数组后，所有处理都应在cellForRowAtIndexPath方法中完成。

将结果数组作为全局而不是取tableData和imageData。

if let url = NSURL(string: "http://motherofall.org/sites/default/files/blog/Ignorance.png") {
    if let data = NSData(contentsOfURL: url){
        cell.imageView.contentMode = UIViewContentMode.ScaleAspectFit
        cell.imageView.image = UIImage(data: data)
    }
}

按照this帖子在tableViewCell中异步加载图片。

使用以下代码将图像加载到tableview单元格内的图像视图中。

class Offers
{
    /**
     * @var string
     * @Assert\Length(
     *      min = 5,
     *      max = 64,
     *      minMessage = "El nombre de la oferta debe de tener al menos {{ limit }} caracteres.",
     *      maxMessage = "El nombre de la oferta no puede superar los {{ limit }} caracteres."
     * )
