利用一组图片来实现动画效果，这里在项目中需要一个LoadingView，自定义了一个UIImageView，使用这个只需在需要的位置创建这个UIImageView即可。在这把自定义UIImageView类全部代码分享给大家

import UIKit
class FMLoadingImageViw: UIImageView {
private var images:[UIImage] = []
override init(frame: CGRect) {
super.init(frame: frame)
self.frame = frame
setData()
}
func setData() {
for item in 0..<6 {
images.append(UIImage(named: "С_0000\(item)")!)
}
self.backgroundColor = UIColor.clearColor()
}
func showLoadingView() {
self.animationImages = images
self.animationDuration = 0.25
self.animationRepeatCount = 0
self.startAnimating()
UIView.animateWithDuration(0.25) {
self.alpha = 1
}
}
func hiden() {
UIView.animateWithDuration(0.25, animations: {
self.alpha = 0
}) { (bool) in
self.stopAnimating()
}
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
}
// 使用方法
indector = FMLoadingImageViw(frame: CGRect(x: 0, y: 0, w: indectorWith, h: indectorHeight))
self.addSubview(indector!)
// 使用SnapKit添加约束
indector?.snp_makeConstraints(closure: { (make) in
make.centerX.equalTo(self.snp_centerX)
make.centerY.equalTo(self.snp_centerY)
})
