我是新来的编码,并拿起一些开源项目来获得这个想法.希望你们可以帮助我解决这个问题
let pictures = ( selectedRestaurant["Pictures"] as! NSArray ) //Here's where i get the error
let picture = ( pictures[zoomedPhotoIndex] as! NSDictionary )
let pictureURL = picture["url"] as! String
let imageURL = NSURL(string: pictureURL)
let urlRequest = NSURLRequest(URL: imageURL!)
NSURLConnection.sendAsynchronousRequest(urlRequest,queue: NSOperationQueue.mainQueue()) {
response,data,error in
if error == nil && data != nil {
self.imageView.image = UIImage(data: data!)
self.imageView.contentMode = UIViewContentMode.ScaleAspectFit
}
}
}
}
只需明确指定什么是图片的类型：
所以代替：
let pictures = selectedRestaurant["Pictures"] as! NSArray
写：
let pictures: NSArray = selectedRestaurant["Pictures"] as! NSArray
