Swift中的动画GIF动画

我一直试图在Swift中动画GIF，但它不起作用。我想我找到了一种方式，但有一个错误，请帮助。Swift中的动画GIF动画

下面的代码：

@IBOutlet var imageView: UIImageView! 
override func viewDidLoad() { 
    super.viewDidLoad() 

    // Do any additional setup after loading the view. 
    // (Here is the error it states "Cannot assign a value of type '[UIImage?]' to a value of type '[UIImage]?'") 
    imageView.animationImages = [ 

     UIImage(named: "logo1.jpg"), 
     UIImage(named: "logo2.jpeg"), 
     UIImage(named: "logo3.png") 
    ] 

    imageView.animationDuration = 3 
    imageView.startAnimating() 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
    // ... 
}

你只需要通过解开返回的UIImage可选的UIImage（名为:)方法。像这样尝试：

class ViewController: UIViewController { 
    @IBOutlet weak var imageView: UIImageView! 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 
     imageView.animationImages = [ 
      UIImage(named: "logo1")!, 
      UIImage(named: "logo2")!, 
      UIImage(named: "logo3")!] 

     imageView.animationDuration = 3 
     imageView.startAnimating() 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 


}

这仍然不起作用，因为问题是imageView.animationImages –

你能详细说明这个原因吗？ –

我不知道为什么 –

你可以直接运行gif文件，按照下面的链接;

至于在你的代码是问题，因为已经“狮子座Dabus”指出的那样，是你是不是未包裹的UIImage实例。尝试使用相同的代码进行以下修改。

imageView.animationImages = [ 

     UIImage(named: "logo1.jpg")!, //File Extension would not be required if .png 
     UIImage(named: "logo2.jpeg")!, //File Extension would not be required if .png 
     UIImage(named: "logo3.png")! 
    ] 

    imageView.animationDuration = 3 
    imageView.startAnimating()

我已经为您创建了一个示例。

这里是代码：

import UIKit 

class ViewController: UIViewController { 

    @IBOutlet weak var imageView: UIImageView! 
    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 
     imageView.animationImages = [ 
      UIImage(named: "1")!, 
      UIImage(named: "2")!, 
      UIImage(named: "3")!, 
      UIImage(named: "4")!, 
      UIImage(named: "5")!, 
      UIImage(named: "6")!, 
      UIImage(named: "7")!, 
      UIImage(named: "8")!, 
      UIImage(named: "9")!, 
      UIImage(named: "10")!, 
      UIImage(named: "11")!, 
      UIImage(named: "12")! 

     ] 

     imageView.animationDuration = 3 
     imageView.startAnimating() 
    } 
}

你可以看到结果HERE。

和HERE是示例项目。
