在项目开发中经常性的要跳转控制器,然而每次都要导入控制器的头文件 这样一来有点麻烦 故此有一些方法可以偷懒的办法(程序员就是要不但的“偷懒”才能进步不是吗) 进入正题吧 如何实现这样的功能了? 肯定少比了runtime的事了

一.新建一个文件如下:RDRouterManager.h
//
// RDRouterManager.h
// RD
//
// Created by 易东 on 2019/10/18.
// Copyright © 2019 易东. All rights reserved.
//

import <Foundation/Foundation.h>

NS_ASSUME_NONNULL_BEGIN

typedef void(^RDRouterBlock) (id backData);

@protocol RDRouterManagerDelegate <NSObject>

@optional
//可以用字典 传一些属性值

• (void)loadParam:(NSDictionary *)parameters;

@end

/// 路由的管理

@interface UIViewController(RDRouterManager)<RDRouterManagerDelegate>

@property (nonatomic,copy,nullable)RDRouterBlock lhz_RouterBlock;

• (void)pushViewControllerName:(NSString *)vcName;

• (void)pushViewControllerName:(NSString *)vcName
  animated:(BOOL)animated;

• (void)pushViewControllerName:(NSString *)vcName
  param:(NSDictionary *)aParam;

• (void)pushViewControllerName:(NSString *)vcName
  param:(NSDictionary *)aParam
  routerBlock:(RDRouterBlock)routerBlock;

• (void)pushViewControllerName:(NSString *)vcName
  param:(NSDictionary *)aParam
  animated:(BOOL)animated
  routerBlock:(RDRouterBlock)routerBlock;

@end

NS_ASSUME_NONNULL_END

二.实现文件如下:RDRouterManager.m

import "RDRouterManager.h"

import <objc/runtime.h>

//这个是导航栏控制器的基类 可以使用你们自己封装的

import "BaseNavigationController.h"

typedef enum : NSUInteger {
RDRouterTypePush,
RDRouterTypePresent
} RDRouterType;

pragma clang diagnostic push

pragma clang diagnostic ignored "-Wnonnull"

@implementation UIViewController(RDRouterManager)

pragma mark ---- 属性赋值

• (void)paramToVc:(UIViewController *) v param:(NSDictionary *)parameters{
  if (parameters) {
  unsigned int outCount = 0;
  objc_property_t * properties = class_copyPropertyList(v.class , &outCount);
  for (int i = 0; i < outCount; i++) {
  objc_property_t property = properties[i];
  NSString *key = [NSString stringWithUTF8String:property_getName(property)];
  NSString *param = parameters[key];
  if (param != nil) {
  [v setValue:param forKey:key];
  }
  }
  }
  }

• (void)pushViewControllerName:(NSString * __nonnull)vcName {
  [self pushViewControllerName:vcName
  param:nil
  animated:YES
  routerBlock:nil];
  }

• (void)pushViewControllerName:(NSString * __nonnull)vcName
  animated:(BOOL)animated {
  [self pushViewControllerName:vcName
  param:nil
  animated:animated
  routerBlock:nil];
  }

• (void)pushViewControllerName:(NSString * __nonnull)vcName
  param:(NSDictionary *)aParam {
  [self pushViewControllerName:vcName
  param:aParam
  animated:YES
  routerBlock:nil];
  }

• (void)pushViewControllerName:(NSString * __nonnull)vcName
  param:(NSDictionary * __nullable)aParam
  animated:(BOOL)animated {
  [self pushViewControllerName:vcName
  param:aParam
  animated:animated
  routerBlock:nil];
  }

• (void)pushViewControllerName:(NSString *)vcName
  param:(NSDictionary *)aParam
  routerBlock:(RDRouterBlock)routerBlock {
  [self routerViewControllerName:vcName
  param:aParam
  routerType:RDRouterTypePush
  animated:YES
  routerBlock:routerBlock];
  }

• (void)pushViewControllerName:(NSString *)vcName
  param:(NSDictionary *)aParam
  animated:(BOOL)animated
  routerBlock:(RDRouterBlock)routerBlock {
  [self routerViewControllerName:vcName
  param:aParam
  routerType:RDRouterTypePush
  animated:animated
  routerBlock:routerBlock];
  }

• (void)presentViewControllerName:(NSString *)vcName
  param:(NSDictionary *)aParam
  animated:(BOOL)animated
  routerBlock:(RDRouterBlock)routerBlock {
  [self routerViewControllerName:vcName
  param:aParam
  routerType:RDRouterTypePresent
  animated:animated
  routerBlock:routerBlock];
  }

• (void)routerViewControllerName:(NSString * __nonnull)vcName
  param:(NSDictionary * __nullable)aParam
  routerType:(RDRouterType)rType
  animated:(BOOL)animated
  routerBlock:(RDRouterBlock)routerBlock{
  //跳转
  //获取控制器
  Class cls = NSClassFromString(vcName);
  if (!cls) {
  return;
  }
  UIViewController *vc = [[cls alloc] init];

  //参数解析
  [self paramToVc:vc param:aParam];
  if ([self respondsToSelector:@selector(loadParam:)]) {
  [self loadParam:aParam];
  }

  if (rType == RDRouterTypePush) {
  if ([self isKindOfClass:[UINavigationController class]]) {
  //当前控制器本身就是一个导航控制器
  [(UINavigationController *)self pushViewController:vc animated:animated];

    }else {
        //控制器存在堆栈中
        if (self.navigationController) {
            [self.navigationController pushViewController:vc animated:animated];
        }
    }
  

  }else {
  BaseNavigationController *nav = [[BaseNavigationController alloc] initWithRootViewController:vc];
  if ([self isKindOfClass:[UINavigationController class]]) {
  //当前控制器本身就是一个导航控制器
  [(UINavigationController *)self presentViewController:nav animated:animated completion:nil];
  }else {
  //控制器存在堆栈中
  if (self.navigationController) {
  [self.navigationController presentViewController:nav animated:animated completion:nil];
  }else {
  [self presentViewController:nav animated:animated completion:nil];
  }
  }
  }
  if (routerBlock) {
  [vc setLhz_RouterBlock:routerBlock];
  }
  }

pragma clang diagnostic pop

static char JZTCallBackBlockKey;

• (void)setLhz_RouterBlock:(RDRouterBlock)lhz_RouterBlock {
  objc_setAssociatedObject(self, &JZTCallBackBlockKey, lhz_RouterBlock, OBJC_ASSOCIATION_COPY_NONATOMIC);
  }

• (RDRouterBlock)lhz_RouterBlock{
  return objc_getAssociatedObject(self, &JZTCallBackBlockKey);
  }

@end

三.调用事例:
1.[self.navigationController pushViewControllerName:@"xxxVC" animated:YES];

2.[self.navigationController pushViewControllerName:@"xxxVC" param:@{@"model":xxx}];
xxxVC控制器中有属性指model 可以用字典传值 在xxxVC控制器中就可以直接使用传过来的值了
是不是非常方便.......
