我有一个plist在我的项目中运行，其中包含图像urls数量。我试图将URL图像传递给我的imageView这是在同一viewController.I发现类似的问题从github像Loading/Downloading image from URL on Swift,Swift - Read plist,Can't get plist URL in Swift我经历了所有这些答案，但迄今为止没有运气，而不是致命的崩溃。我的部分代码如下....从Plist加载网址图像在Swift

方法1：

override func viewDidLoad() { 
    super.viewDidLoad() 

    if let path = Bundle.main.path(forResource: "apps", ofType: "plist"), 
     let root = (NSArray(contentsOfFile: path)) 
    { 
     let url = NSURL(string: path) 
     let data = NSData(contentsOf: url! as URL) 
     if let imageData = data { 
     imageView.image = UIImage(data: imageData as Data) 
    } 

     **// Swift Console Printinging as Follows** 

     print(root) 
     // printing all my plist url links like {icon = "https://xxxxxxxxxxx.com/image/girl_face_freckles_eyes_92358_1920x1080.jpg";} 

     print(url) 
     // (/Users/xxxxxx/Library/Developer/CoreSimulator/Devices/52DA3F73-83E0-4C29-9DE1-D8D5F0731C13/data/Containers/Bundle/Applica ... ps.plist) 

     print(data) 
     // nil 

     print(imageView.image) 
     //nil 
    } else { 
     print("Either the file does not exist or the root object is an array") 
    }

方法2：

let path = Bundle.main.path(forResource: "apps", ofType: "plist") 
    let url = NSURL(string: path!) 
    let imgData = try? Data(contentsOf: url as! URL) 
    let img = UIImage(data: imgData!)! 

    print(img) // fatal crash 

}

答

path是通向你的plist中，而不是图像的URL。

图像URL位于“root”数组中的“图标”键中。

获取数组下标与键的第一个项目，你应该把你的图片网址：

if let item = root[0] as? [String:Any] { 
    if let result = item["icon"] as? String { 
     print(result) 
    } 
}

在(NS)Bundle的path是一个文件系统路径和这些路径必须与URL(fileURLWithPath:)创建

let path = Bundle.main.path(forResource: "apps", ofType: "plist") 
let url = URL(fileURLWithPath: path!)

但为什么没有人使用的URL相关的API，它是更方便

let url = Bundle.main.url(forResource: "apps", withExtension: "plist")
