Describe the bug
我的项目中使用了最新的afnetworking框架3.2.1。pod引入JJException后，按照文档设置好，使用了JJExceptionGuardAll，这个时候运行app大概率会crash，提示afn相关的"KVO removeObserver did not exist key:%@ observer:%@"异常提示并crash。
然后修改配置，去掉KVO相关异常的guard，再运行app就正常了

你不是说避免崩溃吗？ 我点击第三个button咋崩溃？这个如何应用？

每个对象都要写一个同样的方法，感觉不太好啊

Describe the bug
在didFinishLaunchingWithOptions启动startGuardException（含有JJExceptionGuardKVOCrash）与发起网络请求，有一定概率在AFURLSessionManager 142行
progress.totalUnitCount = NSURLSessionTransferSizeUnknown; 崩溃（Thread 1: EXC_BAD_ACCESS）
configExceptionCategory 不含 JJExceptionGuardKVOCrash 则正常
具体闪退规律暂没有找到

xcode版本:xcode 10.0

Podfile文件内容如下:
platform:ios, '9.0'

target 'TestJJException' do
pod 'JJException'
end

终端安装报错: [!] Unable to find a specification for JJException
尝试pod search JJException
结果报错:[!] Unable to find a pod with name, author, summary, or description matching JJException

pod search AFNetworking 等其他第三方库正常

步骤：

1、[self.textField becomeFirstResponder]；// 打开键盘 （无报错）

2、[[[UIApplication sharedApplication] keyWindow] endEditing:YES];  // 关闭键盘 （报错啦！）

Describe the bug
在KVO的时候没有消息通知

Please complete the following information

• JJException 0.1.1
• ReactiveCocoaObjC 3.1.0

这不是一个bug 上面内容为你说明的原话，其实你说的“无法提示那些keyPath忘记清理”是可以在相关函数中提示的
1、清除不存在的key也会闪退：hookRemoveObserver里面checkKVOItemExist里面没有else
2、添加监听后没有清除会导致闪退：clearKVOData的时候其实如果正常的话 set里面应该是没有说句的 有数据说明不正常 不正常就要上报
3、添加重复的key导致闪退：hookAddObserver里面的checkKVOItemExist也是没有else

没有恶意啊 我发现 你写代码if都没有else啊 😁😁😁...

你好，请教一个问题。
官方文档写到： 如果方法成功添加，则返回“是”，否则为“否”。
那么为什么会出现添加失败

 Class metaclass = objc_getMetaClass(NSStringFromClass(cls).UTF8String);
class_addMethod(metaclass,
                                       originSelector,
                                       method_getImplementation(swizzleSelector),
                                       method_getTypeEncoding(swizzleSelector));

你好，

mrc下的几个文件用了weak的property，
需要改成assign，

hookSubstringFromIndex: NSMutableString(MutableStringHook)

hookSubstringToIndex: NSMutableString(MutableStringHook)

开启JJExceptionGuardKVOCrash后，AVFoundation加载本地视频资源偶现只有声音没有视频的异常，关闭则正常，设备版本iOS11 iOS12 都可以复现，视频格式mp4，编码264，目前只有加载本地视频有这个问题。播放的逻辑是检查到AVPlayerItem.status == AVPlayerItemStatusReadyToPlay 则开始播放。

点击stop guard 闪退 - (void)hookDealloc 死循环
在IOS 12 xcode 10.0

如果能处理，能定位崩溃位置吗

(void) hookAddObject:(id)object {
if (object) {
[self hookAddObject:object];
} else {
handleCrashException(JJExceptionGuardArrayContainer,@"NSSet addObject nil object");

}这个方法会造成循环调用吗？

请问作者: 目前这个库稳定了吗, ios11 ->> ios12是否有问题?

Describe the bug
在didFinishLaunchingWithOptions启动startGuardException，包含JJExceptionGuardKVOCrash，在运行到AFURLSessionManagerTaskDelegate中的方法- (instancetype)initWithTask:中的162行：

[progress addObserver:self forKeyPath:NSStringFromSelector(@selector(fractionCompleted))
options:NSKeyValueObservingOptionNew
context:NULL]

时会存在内存泄漏：

当不含JJExceptionGuardKVOCrash时，不会存在这个问题。

有Swift版本的吗？

有无方法可以全局收集的，例如在根控制器里面实现统一收集？

Describe the bug
开启JJExceptionGuardKVOCrash防护 调用摄像头会闪退
在#import "NSObject+KVOCrash.m"中cleanObservers里面会闪退

• (void)cleanObservers{
  for (KVOObjectItem* item in self.observers) {
  [self.whichObject removeObserver:item.observer forKeyPath:item.keyPath];
  }
  }

打印出 item.observer 是

会在object_getClass(self.whichObject) 崩溃,麻烦看下

// 使用参数NSKeyValueObservingOptionInitial就会崩溃
// 仅使用NSKeyValueObservingOptionNew|NSKeyValueObservingOptionPrior|NSKeyValueObservingOptionOld这些参数不会发生崩溃

总是断点在NSObject+KVOCrash.m P297行，是抓取到crash信息了吗，
[self hookRemoveObserver:observer forKeyPath:keyPath];

有时会断在方法cleanKVOData中的@Try中，不知道是否因为同FBKVOController一起使用导致的，麻烦告知一下，谢谢

  我下载demo，运行demo，点击push contronller，
  最后还是奔溃了，不明白保护的效果指的是什么

在- (void)clearKVOData方法中objc_msgSend这一行崩溃,上次是在上一行代码object_getClass(self.whichObject),麻烦看一下!

NSString,NSMutableString,NSAttributedString,NSMutableAttributedString(下标越界以及参数nil异常)
缺少 NSMutableAttributedString replaceCharactersInRange 越界的拦截
也属于平常常遇到的crash
在用户快速切换语音输入根键盘输入的时候 如果执行这类替换方法会很容易崩，非常感谢

我在读你的源码,有个地方不太理解:

链接

NSObject+UnrecognizedSelectorHook.m --> methodSignatureForSelectorSwizzled --> 32行

    // If current class override methodSignatureForSelector return nil
    if (originIMP != currentClassIMP){
        return nil;
    }

这里返回nil的话,不就直接crash了吗?

对于开启kvo异常处理时，对于10.x(测试系统版本10.3.3)系统版本存在自己实现kvo 到remove时，会与JJException的dealloc中clearKVOData一起导致多次remove而crash. 测试环境可以在YYText与此框架同时启用时，具有多次键盘关闭情况下复现。

使用这个对性能有没有影响

这个库会影响上线审核吗，会被苹果拒绝吗？
