swift 4.2 - 根据字符串 push指定控制器

俩个方法 

 

1. 创建类写成 类方法

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

import UIKit /*  * 注释：获得VC  * 1.字符串 和使用的控制器，直接跳转  * 2.用过字符串获得对应VC  */ class JYGetPushVc: NSObject {       /// 指定字符串VC跳转,设置title     static func pushVcByVcNameAndTitle(pushVcNameStr:String, pushVcTitleStr:String? = nil, weakVc:UIViewController?){         guard let namespace = Bundle.main.infoDictionary?["CFBundleExecutable"]as? String else{             return debugPrint("JYGetPushVc 调用 pushVcByVcNameAndTitle, namespace不存在")         }         let clsName = namespace + "." + pushVcNameStr         guard let cls = NSClassFromString(clsName) as? UIViewController.Type else{             return debugPrint("JYGetPushVc 调用 pushVcByVcNameAndTitle, 项目中没有控制器 === \(pushVcNameStr)")         }         let vc = cls.init()         if let titleStr = pushVcTitleStr{             vc.title = titleStr         }         weakVc?.navigationController?.pushViewController(vc, animated: true)     }           /// 根据字符串获得对应控制器，使用的时候as, 传递参数     static func getVc(pushVcNameStr:String) -> UIViewController?{                   guard let namespace = Bundle.main.infoDictionary?["CFBundleExecutable"]as? String else{             debugPrint("JYGetPushVc 调用 getVc, namespace不存在")             return nil         }         let clsName = namespace + "." + pushVcNameStr         guard let cls = NSClassFromString(clsName) as? UIViewController.Type else{             debugPrint("JYGetPushVc调用getVc项目中没有 控制器 === \(pushVcNameStr)")             return nil         }         return cls.init()     } }

　　

类使用

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {       //这里 VC需要传递参数进去的     var pushVc : UIViewController?       if let vc = JYGetPushVc.getVc(pushVcNameStr: vcNameArr[indexPath.section][indexPath.row]) as? JYWorksShowController{         vc.title = titleArr[indexPath.section][indexPath.row]         pushVc = vc     }           //这是主页面看需求隐藏tabbar     self.hidesBottomBarWhenPushed = true           if let vc = pushVc{         self.navigationController?.pushViewController(vc, animated: true)     }else{         //这里不需要指定控制器。设置VC的属性的。         JYGetPushVc.pushVcByVcNameAndTitle(pushVcNameStr: vcNameArr[indexPath.section][indexPath.row], pushVcTitleStr: titleArr[indexPath.section][indexPath.row], weakVc: self)     }           //跳转打开，不然回到首页 没有tabbar     self.hidesBottomBarWhenPushed = false }

　　

 

 

2. 在当前控制器 写俩方法

方法1

?

1 2 3 4 5 6 7 8 9 10 11

/// 指定字符串VC跳转,设置title    func pushVcByVcNameAndTitle(vcName:String, vcTitleName:String = "", isHideBottomBar:Bool = false){        if let namespace = Bundle.main.infoDictionary?["CFBundleExecutable"]as? String{            let clsName = namespace + "." + vcName            if let cls = NSClassFromString(clsName) as? UIViewController.Type{                let vc = cls.init()                vc.title = vcTitleName                self.navigationController?.pushViewController(vc, animated: true)            }        }    }

　　

方法2

?

1 2 3 4 5 6 7 8 9 10 11

/// 根据字符串获得对应控制器，使用的时候as, 传递参数 func pushVcByVcNameAndTitle(vcName:String) -> UIViewController?{     if let namespace = Bundle.main.infoDictionary?["CFBundleExecutable"]as? String{         let clsName = namespace + "." + vcName         if let cls = NSClassFromString(clsName) as? UIViewController.Type{             let vc = cls.init()             return vc         }     }     return nil }

　　

3.方法使用

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {           //这里 VC需要传递参数进去的         var pushVc : UIViewController?<br><br>       //具体VC 设置 vc的属性         if let vc1 = pushVcByVcNameAndTitle(vcName: vcNameArr[indexPath.section][indexPath.row]) as? JYWorksShowController{             vc1.title = titleArr[indexPath.section][indexPath.row]             //vc1.arr = self.dataArr             //vc1.title = vcTitleArr[index.row]             pushVc = vc1         }           //这是主页面看需求隐藏tabbar         self.hidesBottomBarWhenPushed = true         if let vc = pushVc{             self.navigationController?.pushViewController(vc, animated: true)         }else{             //这里不需要指定控制器。设置VC的属性的。             pushVcByVcNameAndTitle(vcName: vcNameArr[indexPath.section][indexPath.row], vcTitleName: titleArr[indexPath.section][indexPath.row], isHideBottomBar: true)         }         //跳转打开，不然回到首页 没有tabbar         self.hidesBottomBarWhenPushed = false     }
