Tweak.xm 开发怎么引用self.navigationController

我用 cycript 捕捉到WeChat进程 可以调用self.navigationController进行调整开发 self 用地址代替 但是 写入Tweak.xm中确无法调用self.navigationController。 Tweak.xm 也引入过#import <UIKit/UIKit.h>和#import <Foundation/Foundation.h> 请哪位大神指导下

类型转换一下self

不是很明白 我是尝试逆向微信试试看 就 BaseMsgContentViewController 这个类 具体代码 是这个 您帮我看看 我是小白 我把 能想到的引用都写进去了

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface MMUIViewController : UIViewController 
@end

@interface MMSearchBarDisplayController : MMUIViewController
@end

@interface BaseMsgContentViewControlle:MMSearchBarDisplayController

-(void)AsyncSendMessage:(id)arg1;

@end

%hook BaseMsgContentViewController

-(void)viewDidAppear:(BOOL)animated
{
	%orig;

	UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"这是测试" message:
	                      [NSString stringWithFormat:@"%@",self] 
	                      delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
    [alert show];
    [alert release];

    [self.navigationController popViewControllerAnimated:YES];
}

%end
[self.navigationController popViewControllerAnimated:YES];

----------------->>>>>>>>
很多种方法,这种应该是其中之一

[(UIViewController*)[self performSelector:@selector(navigationController)] popViewControllerAnimated:YES];

大佬用你给我方法试试还是不行


大佬是不是我的配置少了什么
下面是错误提示 我没用你给的方法

你这么写的话,编译报什么错?

我的Tweak.xm 是这样的
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface MMUIViewController : UIViewController
@end

@interface MMSearchBarDisplayController : MMUIViewController
@end

@interface BaseMsgContentViewControlle:MMSearchBarDisplayController

-(void)AsyncSendMessage:(id)arg1;

@end

%hook BaseMsgContentViewController

-(void)viewDidAppear:(BOOL)animated
{
%orig;

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"这是测试" message:
                      [NSString stringWithFormat:@"%@",self] 
                      delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alert show];
[alert release];

[self.navigationController popViewControllerAnimated:YES];

}

%end
报的错误是


按照之前大佬提示把
[self.navigationController popViewControllerAnimated:YES];
改成
[(UIViewController*)[self performSelector:@selector(navigationController)] popViewControllerAnimated:YES];

是不是我缺少引用了什么

大哥, popViewControllerAnimated:UINavigationController

navigationController 是微信自己定义的

https://www.google.com/search?Search&q=popViewControllerAnimated%3A

不是吧,UIViewController里有个navigationController的property

你那么写应该是没问题的,你是写的@interface @end,而不是@class,不知道为什么还会报这个错;但是我看编译报错里Tweak.xm的行数,跟你实际贴的代码行数好像对不上。你把完整的Tweak.xm贴出来看看?(注意用markdown语法)

这样?那是我错了

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
// #import “UIViewController.h”

@interface MMUIViewController : UIViewController
@end

@interface MMSearchBarDisplayController : MMUIViewController
@end

@interface BaseMsgContentViewControlle:MMSearchBarDisplayController

-(void)AsyncSendMessage:(id)arg1;

@end

%hook BaseMsgContentViewController

-(void)viewDidAppear:(BOOL)animated
{
%orig;
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@“这是测试” message:
[NSString stringWithFormat:@"%@",self]
delegate:self cancelButtonTitle:@“OK” otherButtonTitles: nil];
[alert show];
[alert release];
[self.navigationController popViewControllerAnimated:YES];

}
%end


试试这样行不行

新建.h文件,把类的声明都放到.h文件中 在给BaseMsgContentViewControlle加个navigationController属性

@interface BaseMsgContentViewControlle:MMSearchBarDisplayController

@property(nonatomic,readonly,strong) UINavigationController *navigationController;
-(void)AsyncSendMessage:(id)arg1;
@end

可以试试把7到11行删掉,然后把13行的MMSearchBarDisplayController改成UIViewController

还是不行 是不是有什么要引用 的 我没引用 我别人 代码 self.navigationController 是可以用的

两个import都去掉试试?

我添加了 还是不行 之前我也试过 之前找到UIViewController 的@property(nonatomic,readonly,strong) UINavigationController *navigationController;还是不行

一样的 是不是 和之前配置theos的问题

[[self navigationController] popViewControllerAnimated:YES];

代码看起来是没问题的,你试试楼上的方法呢
