前言:

MBProgressHUD,是iOS开发中很经典的一个框架,我们可能每个项目,乃至每个ViewController都能用到,越是常用的控件,就更应该简化其调用方式,来优化我们自己的代码.这里我列举出自己常用封装,也建议各位将自己常用的模式也封装起来.

实现效果:

对调用方法进行封装,实现一行代码弹出HUD

实现五种形式:

• 背景半透明显示文字
• 背景透明显示文字
• 背景半透明显示Loading
• 背景透明显示Loading
• 背景透明显示自定义icon+文字

实现方式:

1.新建一个类,并实现创建HUD实例方法.

2.实现显示HUD方法.

3.展示loadingView方法.

4.类Toast只展示文字方法.

5.展示成功,失败类似icon+文字方法.

6.隐藏HUD方法

1.新建一个类,并实现创建HUD实例方法.

     static var hud : MBProgressHUD?
    /// 创建Hud
    ///
    /// - Parameters:
    ///   - view: 加载到哪个View展示.
    ///   - isMask: 是否是蒙层形式,背景半透明.
    private class func createHud(view : UIView? = UIApplication.shared.keyWindow, isMask : Bool = false) -> MBProgressHUD? {
        guard let supview = view ?? UIApplication.shared.keyWindow else {return nil}
        let HUD = MBProgressHUD.showAdded(to: supview
            , animated: true)
        /// 默认不遮盖navigationBar
        HUD.frame = CGRect(x: 0, y: EWScreenInfo.navigationHeight, width: EWScreenInfo.Width, height: EWScreenInfo.Height - EWScreenInfo.navigationHeight)
        HUD.animationType = .zoom
        if isMask {
            /// 蒙层type,背景半透明.
            HUD.backgroundView.color = UIColor(white: 0.0, alpha: 0.4)
        } else {
            /// 非蒙层type,没有背景.
            HUD.backgroundView.color = UIColor.clear
            HUD.bezelView.backgroundColor = UIColor(white: 0.0, alpha: 0.9)
            HUD.contentColor = UIColor.white
        }
        HUD.removeFromSuperViewOnHide = true
        HUD.show(animated: true)
        return HUD
    }

2.实现显示HUD方法.

    /// 直接展示Hud
    ///
    /// - Parameters:
    ///   - message: 显示信息
    ///   - icon: 显示图片
    ///   - view: 加载到哪个View上展示
    ///   - completeBlock: HUD消失后调用block
    private class func showHudTips (message : String?, icon : String?, view : UIView?, completeBlock : (()->(Void))?) {
        let HUD = self.createHud(view: view, isMask: false)
        HUD?.label.text = message
        HUD?.label.numberOfLines = 0
        /// 如果有Icon展示.
        if let icon = icon {
            HUD?.customView = UIImageView.init(image: UIImage.init(named: "\(icon)"))
        }
        HUD?.mode = .customView
        /// 在hud消失时调用completeBlock.
        DispatchQueue.main.asyncAfter(deadline: .now() + hudShowTime) {
            HUD?.hide(animated: true)
            guard let completeBlock = completeBlock else {
                return
            }
            completeBlock()
        }
    }

3.展示loadingView方法.

两个方法,返回实例方法可以根据自己需求修改返回的实例.
调用展示loadingView时,必须在结束loading时手动调用隐藏HUD方法!!!

    /// 展示loadingHUD,可用于网络请求
    class func showLoadingHudView (view : UIView? = UIApplication.shared.keyWindow ,message:String?, isMask : Bool = false){
        let HUD = self.createHud(view: view, isMask: isMask)
        HUD?.mode = .indeterminate
        HUD?.label.text = message
        hud = HUD
    }
    /// 生成实例的loadingHUD,可以再对实例进行自定义修改
    class func showLoadingHudInView (view : UIView? = UIApplication.shared.keyWindow ,message:String?, isMask : Bool = false) -> MBProgressHUD?{
        let HUD = self.createHud(view: view, isMask: isMask)
        HUD?.mode = .indeterminate
        HUD?.label.text = message
        hud = HUD
        return hud
    }

4.类Toast只展示文字方法.

 /// 展示类ToastHUD
    class func showTextHudTips(message : String?, view : UIView? = UIApplication.shared.keyWindow , isMask : Bool = false,afterDelay:Double = hudShowTime) {
        let HUD = self.createHud(view: view, isMask: isMask)
        HUD?.mode = .text
        HUD?.detailsLabel.font = UIFont.systemFont(ofSize: 16.0)
        HUD?.detailsLabel.text = message
        HUD?.hide(animated: true, afterDelay: afterDelay)
    }
    /// 生成实例的类ToastHUD,可以再对实例进行自定义修改
    class func showTextHud (message : String?, view : UIView? = UIApplication.shared.keyWindow , isMask : Bool = false,afterDelay:Double = hudShowTime) -> MBProgressHUD? {
        let HUD = self.createHud(view: view, isMask: isMask)
        HUD?.mode = .text
        HUD?.detailsLabel.font = UIFont.systemFont(ofSize: 16.0)
        HUD?.detailsLabel.text = message
        HUD?.hide(animated: true, afterDelay: afterDelay)
        return HUD
    }

5.展示成功,失败类似icon+文字方法.

本质上是icon+文字形式,传入自己项目图片,建议大小为64X64

// 展示成功HUD,可自己修改图片,icon图片需要自己添加到项目中,建议大小为64X64
    class func showSuccesshTips (message : String?, view : UIView? = UIApplication.shared.keyWindow ,afterDelay:Double = hudShowTime) {
        self.showHudTips(message: message, icon: "Success.png", view: view, completeBlock: nil)
    }
    // 展示成功HUD,可传入HUD隐藏后调用Block
    class func showSuccesshTips (message : String?, view : UIView? = UIApplication.shared.keyWindow , completeBlock : (()->(Void))?) {
        self.showHudTips(message: message, icon: "success.png", view: view, completeBlock: completeBlock)
    }
    // 展示失败HUD,可自己修改图片,icon图片需要自己添加到项目中,建议大小为64X64
    class func showErrorMessage(message : String?, view : UIView? = UIApplication.shared.keyWindow ){
        self.showHudTips(message: message, icon: "error.png", view: view, completeBlock: nil)
    }
    // 展示失败HUD,可传入HUD隐藏后调用Block
    class func showErrorMessage (message : String?, view : UIView? = UIApplication.shared.keyWindow , completeBlock : (()->(Void))?) {
        self.showHudTips(message: message, icon: "error.png", view: view, completeBlock: nil)
    }

6.隐藏HUD方法

    /// 隐藏HUD
    class func hideHud () {
        guard let HUD = hud else {
            return
        }
        HUD.hide(animated: true)
        hud = nil
    }

使用方法示例:

1.使用CocoaPods或手动将MBProgressHUD加入项目.

2.将EWMBProgressHUD.swift文件加入项目.

3.调用时:

@objc private func onClickTopButton(){
    EWMBProgressHud.showTextHudTips(message: "蒙层", view: self.view, isMask: true, afterDelay: 1)
}
@objc private func onClickCenterButton(){
    EWMBProgressHud.showTextHudTips(message: "Toast")
}
@objc private func onClickLoadingButton(){
    EWMBProgressHud.showLoadingHudView(message: "Loading")
    /// loadingView必需手动隐藏!!!结束loading请调用hideHud()!!!
    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 2) {
        EWMBProgressHud.hideHud()
    }
}
@objc private func onClickSecondLoadingButton(){
    EWMBProgressHud.showLoadingHudView(view: self.view, message: "蒙层Loading", isMask: true)
    /// loadingView必需手动隐藏!!!结束loading请调用hideHud()!!!
    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 2) {
        EWMBProgressHud.hideHud()
    }
}
@objc private func onClickSuccessButton(){
    EWMBProgressHud.showSuccesshTips(message: "Success")
}
