iOS零碎知识总结

性解决问题）
2.Generating SSH keys：https://help.github.com/articles/generating-ssh-keys/（虽然没有解决我的问题，但长了不少知识，或许对很多的问题可以起到解决的作用）
后来在我的.ssh目录下增加了config文件，命令如下：$ vim config
在config中需要写入如下内容：
Host git.XX.XX.com
HostKeyAlgorithms +ssh-dss
第一句中的XX.XX大家根据自己的项目中ssh链接查看@后面到‘：’前的一段，格式为git.XX.XX.com.保存文件，重新提交就好了
ssh://hzluoyun1@git.XX.XX.com:XXXXX.git

1：如何给一个Button增加一个可以传递的参数，代码如下：
实现的原理是使用了iOS的“黑魔法” Runtime

UIButton *surebtn = [UIButton buttonWithType:(UIButtonTypeCustom)]; 
 objc_setAssociatedObject(surebtn, "firstObject", backView, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
 objc_setAssociatedObject(surebtn, "callBack", backBlack, OBJC_ASSOCIATION_COPY_NONATOMIC);

然后在btn的事件响应方法里接受该参数

-(void)sureBtnAction:(UIButton*)button{
    UIView *bakView = objc_getAssociatedObject(button, "firstObject");
    SureBtnCallBack sucreback = objc_getAssociatedObject(button, "callBack");
    sucreback();
    [bakView removeFromSuperview];
}

note:注意在使用runtime时候要导入头文件

调试某段代码使用时间：
double start = CFAbsoluteTimeGetCurrent();
NSLog(@"duration---%f", CFAbsoluteTimeGetCurrent() - start);

#import <objc/runtime.h>

这个错误的解决办法
cd ~/Library/Developer/Xcode/DerivedData/
然后再终端输入：xattr -rc .

设置终端翻墙
git config --global http.proxy socks5://127.0.0.1:1086
git config --global http.https://github.com.proxy socks5://127.0.0.1:1086

恢复
git config --global --unset http.proxy
git config --global --unset http.https://github.com.proxy

终端翻墙打开 setproxy
终端关闭：unsetproxy
验证状态 curl -v getip.91jinrong.com
