IOS 获取已连接的wifi信息的实现代码
首先需要 #import <SystemConfiguration/CaptiveNetwork.h>
+ (id)fetchSSIDInfo
{
NSArray *ifs = (id)CNCopySupportedInterfaces();
NSLog(@"%s: Supported interfaces: %@", __func__, ifs);
id info = nil;
for (NSString *ifnam in ifs) {
info = (id)CNCopyCurrentNetworkInfo((CFStringRef)ifnam);
NSLog(@"%@ => %@", ifnam, info);
if (info && [info count]) { break; }
[info release];
}
[ifs release];
return [info autorelease];
}
ARC 版本：
+ (id)fetchSSIDInfo {
NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();
NSLog(@"%s: Supported interfaces: %@", __func__, ifs);
id info = nil;
for (NSString *ifnam in ifs) {
info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
NSLog(@"%@ => %@", ifnam, info);
if (info && [info count]) { break; }
}
return info;
}
