在SWRevealViewController

Question

我在左侧使用SWRevealViewController菜单，我想更改默认动画并制作淡出动画。我尝试了他们的代表如下，但它没有成功。

    func revealController(_ revealController: SWRevealViewController!, animateTo position: FrontViewPosition) {
    if position == .left {
        view.alpha = 0.15
    }
    else if position == .right {
        view.alpha = 1
    }
}

Answer 1

import Foundation
import UIKit

extension UIView {
    func fadeIn(_ duration: TimeInterval = 1.0, delay: TimeInterval = 0.0, completion: @escaping ((Bool) -> Void) = {(finished: Bool) -> Void in}) {
        UIView.animate(withDuration: duration, delay: delay, options: UIViewAnimationOptions.curveEaseIn, animations: {
            self.alpha = 1.0
            }, completion: completion)  }

    func fadeOut(_ duration: TimeInterval = 1.0, delay: TimeInterval = 0.0, completion: @escaping (Bool) -> Void = {(finished: Bool) -> Void in}) {
        UIView.animate(withDuration: duration, delay: delay, options: UIViewAnimationOptions.curveEaseIn, animations: {
            self.alpha = 0.15
            }, completion: completion)
    }
}

现在改变你的功能

func revealController(_ revealController: SWRevealViewController!, animateTo position: FrontViewPosition) {
    if position == .left {
        view.fadeOut()
    }
    else if position == .right {
        view.fadeIn()
    }
}
