我正在试图检测iOS中的热点状态。为此,我需要使用SystemConfiguration
API如下所示
let sc = SCDynamicStoreCreate(nil, "com.apple.wirelessmodemsettings.MISManager" as CFString, nil, nil)
let info = SCDynamicStoreCopyValue(sc, "com.apple.MobileInternetSharing" as CFString)
但是SCDynamicStoreCreate
和SCDynamicStoreCopyValue
并不适用于iOS。我需要修改SCDynamicStore.h
文件,并使这些函数可用于iOS (它们目前仅对Mac可用)。
此链接提到了通过创建重复的头来实现此操作的一种方法。SCDynamicStoreCreate is unavailable: not available on iOS。但这种方法对我来说不是很快的。
如何才能迅速做到这一点?
谢谢

有几种方法你可以做到。
这里有一种方法是Swift,不涉及更改头文件。
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)
