一点心得 - iOS,Swift,React Native,Python...
有一点小疑惑，请教一下，我对这里使用双向链表有点小疑问，既然已经有字典可以用来保存双向链表中某个节点的位置，那为什么不直接用字典来保存这个订阅者呢？而只是保存订阅者的位置，然后再通过位置来操作双向链表，直接用字典不是更方便吗？时间复杂度也是一样的。
方便开源一个MVVM的OC框架么
# Symbols:
地址 大小 文件编号 方法名
# Address Size File Name
0x1000021B0 0x00000109 [ 2] -[ULWBigResponseButton pointInside:withEvent:]
0x1000022C0 0x00000080 [ 3] -[ULWCategoryController liveAPI]
0x100002340 0x00000080 [ 3] -[ULWCategoryController categories]
....
0x1000021B0 加上 size 0x00000109 末地址为 0x1000022B9 但是下一个地址的起始并不是 0x1000022BA 所以可以知道这个地方的地址并不连续，我猜想这个地方的不连续是不是跟文件编号有关，是不是文件编号相同的地址就是连续的，我理解这样是因为编号相同就是在同一个文件当中，那么这个当中的方法可以连续在一起编译，而不同文件中的方法即文件编号不同则需要放在不连续的内存中，相当于划分了一个块？再猜想的话会不会是针对每一个文件有固定的这样位置的大小，然后用不完的话就放在那里然后跳过使用下一个文件专属的块？
自定义 module 的 framework build 后, 并不会包含 module 中的代码,
而是通过 search path 去原路径寻找的, 如果把 framework 项目的路径修改,
或者把framework 丢个别人都会报 Missing required module
module 之间应该应该都是相互引用的, 并不会直接编译到二进制文件中,
查了好久还没有查到解决办法
关于深入理解ARC.md 这章的理解其中关于autoreleasepool有一点是不对的吧
__weak NSObject * obj;
@autoreleasepool {
NSObject * temp = [[NSObject alloc] init];
obj = temp;
}
这段代码是不会加入pool的，通过alloc创建的自己会管理不会放入pool。释放是因为超过作用域自然会释放局部变量。
可以这么写NSObject * temp = [NSObject creatObj];在MRC下是肯定加入pool，但是在ARC下这块通过tls存储进行了优化省去了发送autorelease和retain操作，并不一定加入pool。
objc 代码 编译生成 objc_msgSend 函数, 那应该是在 编译过程中产生的吧,具体是哪一步?; runtime 是不是就是个 动态库；objc_msgSend 就是runtime动态库里的方法, 最后会链接,装载成 执行文件吗？
望指教.

}第二次字段响应不符合官方文档的说明啊???请问这是什么情况???
还有我看了您的记录 , 说是Server用最后一次票据去轮询验证 , 最后一次票据具体是指???
在framework库里混编的时候，oc调用swift，swift必须是public，这样swift就可以被外界访问了。有没有办法避免对外暴露。
最近更新自己的App的时候，总是卡在鉴权这一步
最后搜了搜，在Mac App Store下载Transporter，然后用它上传，最后成功了。
关于strong和weak的理解：
NSObject * temp = [[NSObject alloc] init];
__strong NSObject * temp = [[NSObject alloc] init];
这样有什么区别呢？
arc中没有strong和weak能不能正常运行？
你好，在《深入浅出iOS编译》有个疑惑，这里LLVM LR，是书写错误吗？
https://blog.csdn.net/Hello_Hwc/article/details/85226147
背景：需要升级Watch OS5 Beta版本来开发一些新功能，手机：iPhone 7，手表：iWatch 3
坑：
解决办法：
小结：手机必须先删除iOS 12 Beta Profile才能连接到表；必须安装上iOS 12 Beta Profile才能更新Watch OS
LLVM本质上只是一个缩写
博主的文章写的很好，仔细阅读时发现一出语句问题：
《优雅的开发TableView》中：
“继承是一个实现代码复用的解决方案，通过在基类中实现-子类重写的方式进行服复用。”
结尾应该是多了一个“服”。
不算是一个问题，阅读时发现，顺手提一下～
未绑定App Store支付方式的用户，在购买内购商品时，首先会弹出一个设置支付方式的弹框，用户点击了继续，updatedTransactions会回调一个是失败的交易，也就是SKPaymentTransactionStateFailed，此时APP 调用了finishTransaction，结束了当前交易，而用户跳转到App Store绑定支付方式之后，接着付款成功了。此时APP还会调用updatedTransactions函数回调成功的交易吗？
