Defining the file a UIImage will use (Swift)
提问by user3708335
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:
因此，我环顾了苹果网站上的开发人员库，但找不到任何说明如何使用 swift 语言说明用于 UIImage 的文件（如 png）的文档。所以我尝试尝试使用以下代码：
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
}
}
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.
我试图做的是动画一个永无止境的两个图像系列。我定义了两个 UIImages（大标题和小标题）并且想知道我如何定义用于那些 UIImage 的 wat .png。我知道这是一个非常基本和新手的问题，但会得到任何帮助。

Even though you are using Swift, all the classes that come from UIKitand other libraries still are written in Objective-C.
即使您使用的是 Swift，来自UIKit其他库的所有类仍然是用 Objective-C 编写的。
There is no difference in the interfaces to these libraries, just the syntax.
这些库的接口没有区别，只是语法不同。
In this case, you need to use the object construction syntax:
在这种情况下，您需要使用对象构造语法：
var image = UIImage(named:"ImageName")
