我正在尝试检测 iOS 中的热点状态。为此,我需要SystemConfiguration
按如下方式使用API
let sc = SCDynamicStoreCreate(nil, "com.apple.wirelessmodemsettings.MISManager" as CFString, nil, nil)
let info = SCDynamicStoreCopyValue(sc, "com.apple.MobileInternetSharing" as CFString)
但SCDynamicStoreCreate
和SCDynamicStoreCopyValue
不适用于 iOS。我需要修改SCDynamicStore.h
文件并使这些功能可用于 iOS(它们目前标记为仅可用于 Mac)。
此链接提到了一种通过创建重复标题来执行此操作的方法。SCDynamicStoreCreate 不可用:在 iOS 上不可用。但是这种方法对我来说很快就不起作用。
如何快速实现这一目标?
谢谢
有几种方法可以做到这一点。
这是一种完全 Swift 并且不涉及更改头文件的方法。
import SystemConfiguration
// Define types for each of the calls of interest
typealias TSCDynamicStoreCreate = @convention (c) (_ allocator: CFAllocator?, _ name: CFString, _ callout: SystemConfiguration.SCDynamicStoreCallBack?, _ context: UnsafeMutablePointer<SCDynamicStoreContext>?) -> SCDynamicStore?
typealias TSCDynamicStoreCopyValue = @convention (c) (_ store: SCDynamicStore?, _ key: CFString) -> CoreFoundation.CFPropertyList?
// Get a handle to the library, the flag `RT_NOLOAD` will limit this
// to already loaded libraries
let hLibrary = dlopen("/System/Library/Frameworks/SystemConfiguration.framework/SystemConfiguration", RTLD_NOLOAD);
// Load addresses of the functions from the library
let MySCDynamicStoreCreate = unsafeBitCast(dlsym(hLibrary, "SCDynamicStoreCreate"), to: TSCDynamicStoreCreate.self)
let MySCDynamicStoreCopyValue = unsafeBitCast(dlsym(hLibrary, "SCDynamicStoreCopyValue"), to: TSCDynamicStoreCopyValue.self)
// Setup constants
let name = "com.apple.wirelessmodemsettings.MISManager" as CFString
let key = "com.apple.MobileInternetSharing" as CFString
// Call the functions through the looked up addresses
let dynamicStore = MySCDynamicStoreCreate(nil, name, nil, nil)
let plist = MySCDynamicStoreCopyValue(dynamicStore, key)
dump(plist)
