1.
项目中用到获取WiFi信息：
BSSID = "24:69:68:98:31:2a";
SSID = "WiFi名";
SSIDDATA = ;
-(NSDictionary *)getWifiInfo{
NSArray *ifs = (__bridge_transfer id)(CNCopySupportedInterfaces());
//NSLog(@"interface %@", ifs);
NSDictionary *info = nil;
for (NSString *ifname in ifs) {
info = (__bridge_transfer NSDictionary *)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifname);
NSLog(@"%@ => %@", ifname, info);
}
return info;
}
遇到问题：iOS 12 后 CNCopySupportedInterfaces 返回WiFi信息为空
解决方式：iOS 12 后增加了 access WiFi information 选项 需要开启
同时AppID支持下

2. 升级xcode10 后 包大了 5.3M
前后两个版本：
代码级别删除僵尸代码、及废弃的类文件
图片无增减
前后xcode 9.3.1 -
