快速修改SCDynamicStore.h的头文件
问题描述:
我试图在iOS中检测到热点状态。为此,我需要使用SystemConfiguration
的API如下快速修改SCDynamicStore.h的头文件
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
不支持iOS。我需要修改SCDynamicStore.h
文件并使这些功能可用于iOS(它们目前仅标记为仅适用于Mac)。
此链接提到了创建重复标题的方法.. SCDynamicStoreCreate is unavailable: not available on iOS。但是这种方法并不适合我。
这是如何在swift中实现的?
谢谢
答
有几种方法可以做到这一点。
这是一种全部是Swift并且不涉及修改头文件的方法。
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)
谢谢@idz ...它工作得很好 – Suraj
