获取window上的view方法演示

1、回调函数写法 ,获取window上的view 获取被点击的UICollectionViewCell 获取手机通讯录 iOS去除数字以外的所有字符 获取通讯哭信息代码 C/C+代码 #include stdafx.h#include #include int main() namespace ip = boost:asio:ip; boost:asio:io_service io_service; /计算时间差 / Client binds to any address on port 8888 (the same port on which / broadcast data is sent f

2、rom server). ip:udp:socket socket(io_service, ip:udp:endpoint(ip:udp:v4(), 8888); ip:udp:endpoint sender_endpoint; /关于NSDate时间的基础使用 / Receive data. /boost:array buffer; char buf500 = 0 ; std:size_t bytes_transferred = socket.receive_from(boost:asio:buffer(buf), sender_endpoint); std:cout got bytes_t

3、ransferred bytes. buf std:endl;代码 C/C+代码 #include stdafx.h#include / 关于Key-Value存储工具类int main() namespace ip = boost:asio:ip; boost:asio:io_service io_service; / Server binds to any address and any port. ip:udp:socket socket(io_service, ip:udp:endpoint(ip:udp:v4(), 0); socket.set_option(boost:asio:s
