Small code example for you. Use array and for loop to do this.
给你的小代码示例。使用数组和 for 循环来做到这一点。
//add images to the array
var imagesListArray :NSMutableArray = []
//use for loop
for position in 1...5
{
var strImageName : String = "c\(position).png"
var image = UIImage(named:strImageName)
imagesListArray.addObject(image)
}
self.imageView.animationImages = imagesListArray;
self.imageView.animationDuration = 1.0
self.imageView.startAnimating()
