定义UIImage将使用的文件（Swift） [英] Defining the file a UIImage will use (Swift)

问题描述

所以我浏览了苹果网站上的开发者库，我找不到任何文档说明如何使用swift语言来说明用于UIImage的文件（如png）。
所以我尝试使用这段代码：

So I looked around the developer library on apple's site and I couldn't find any documentation that said how to state what file (like a png) to use for a UIImage using the swift language. So I try experimenting with this code:

class ViewController: UIViewController {

@IBOutlet var maintitle: UIImageView

var bigtitle: UIImage!
var smalltitle: UIImage!


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib. 

    func startAnimating(){
        var animatedtitle: AnyObject[] = [bigtitle, smalltitle]
        var animationDuration: NSTimeInterval = 0.15
        var animationRepeatCount: Int = 0
    }
}

我试图做的是动画永无止境系列的两个图像。我定义了两个UIImages（bigtitle& small title），并且想知道如何定义用于那些UIImage的wat .png。我知道这是一个非常基本和新手的问题，但任何帮助都会很愉快。

What I was trying to do there was animate a never ending series of two images. I defined two UIImages (bigtitle & small title) and was wondering how I define wat .png's to use for those UIImage's. I know this is a very basic and novice question but any help would be enjoyed.

推荐答案

即使您使用的是Swift，所有来自 UIKit 的类和其他库仍然是用Objective-C编写的。

Even though you are using Swift, all the classes that come from UIKit and other libraries still are written in Objective-C.

没有区别这些库的接口，只是语法。

There is no difference in the interfaces to these libraries, just the syntax.

在这种情况下，您需要使用对象构造语法：

In this case, you need to use the object construction syntax:

var image = UIImage(named:"ImageName")
