当我尝试在我的iPhone上检查互联网连接时,我收到了一堆错误.任何人都可以帮我解决这个问题吗？

代码:

import Foundation
import SystemConfiguration

public class Reachability {

class func isConnectedToNetwork() -> Bool {

    var zeroAddress = sockaddr_in()
    zeroAddress.sin_len = UInt8(sizeofValue(zeroAddress))
    zeroAddress.sin_family = sa_family_t(AF_INET)

    let defaultRouteReachability = withUnsafePointer(&zeroAddress) {
        SCNetworkReachabilityCreateWithAddress(nil, UnsafePointer($0))
    }

    var flags: SCNetworkReachabilityFlags = 0

    if SCNetworkReachabilityGetFlags(defaultRouteReachability, &flags) == 0 {
        return false
    }

    let isReachable = (flags & UInt32(kSCNetworkFlagsReachable)) != 0
    let needsConnection = (flags & UInt32(kSCNetworkFlagsConnectionRequired)) != 0

    return (isReachable && !needsConnection) ? true : false
}

}

代码中的错误:

如果不可读,错误1说:

'Int'不能转换为'SCNetworkReachabilityFlags'

错误2和3:

找不到接受提供的参数的'init'的重载

在iOS框架中,如何检查用户是否启用了Wifi无线电？请注意,我对通过Wifi的可达性不感兴趣,而是用户关闭了设备.谢谢.

请告诉我,我怎么知道目前在objective-c或swift中工作的"wifi"适配器？

谢谢!
