To The Apples Core
1.0.0
Ke inti apel berfungsi sebagai rumah untuk menguji batas -batas apa yang dapat dilakukan pada iOS asli tanpa jailbreak.
Proyek ini adalah untuk tujuan pendidikan dan kode tidak boleh digunakan dalam aplikasi apa pun yang ditargetkan untuk App Store.
Semua proyek dan cuplikan dibuat untuk dan dijalankan pada perangkat yang tidak jenderal . Meskipun belum teruji, sebagian besar cuplikan berikut harus dapat berjalan di taman bermain di iPad.

/**
Obtains an array of dictionaries representing device battery info. Returns nil if there was an issue retrieving info from battery API.
*/
func deviceBatteryInfo ( ) -> [ [ String : AnyObject ] ] ? {

Saya telah membuat seluruh proyek di sekitar ide yang disebut AppExplorer ini. Lihat repo untuk info lebih lanjut dan bagaimana Anda dapat mengimplementasikannya di proyek Anda sendiri.
class AirplaneManager {
/**
Whether or not airplane mode is enabled. Returns nil if an error occured getting info from API.
*/
static func isAirplaneModeEnabled ( ) -> Bool ? {
guard case let handle = dlopen ( " /System/Library/PrivateFrameworks/AppSupport.framework/AppSupport " , RTLD_LAZY ) , handle != nil ,
let c = NSClassFromString ( " RadiosPreferences " ) as? NSObject . Type else {
return nil
}
let radioPreferences = c . init ( )
if radioPreferences . responds ( to : NSSelectorFromString ( " airplaneMode " ) ) {
return ( radioPreferences . value ( forKey : " airplaneMode " ) as AnyObject ) . boolValue
}
return false
}
}
print ( " Airplane Mode Enabled: ( AirplaneManager . isAirplaneModeEnabled ( ) ) " ) Untuk menggunakan fungsi scdynamicstorecreate dan scdynamicstorecopyvalue, makro __OSX_AVAILABLE_STARTING perlu diubah untuk fungsi -fungsi ini.
Cara termudah untuk melakukan ini adalah ⌘ + ⌥ + CLICK pada nama fungsi di Xcode yang akan membawa Anda ke header masing -masing. Komentari makro seperti yang terlihat di sini:
SCDynamicStoreRef __nullable SCDynamicStoreCreate (
CFAllocatorRef __nullable allocator,
CFStringRef name,
SCDynamicStoreCallBack __nullable callout,
SCDynamicStoreContext * __nullable context
) /* __OSX_AVAILABLE_STARTING(__MAC_10_1,__IPHONE_NA) */ ; CFPropertyListRef __nullable SCDynamicStoreCopyValue (
SCDynamicStoreRef __nullable store,
CFStringRef key
) /* __OSX_AVAILABLE_STARTING(__MAC_10_1,__IPHONE_NA) */ ;
let reader = MobileHotspotReader . sharedReader
print ( " Connected Devices: ( reader . numberOfConnectedDevices ) " )
print ( " Connected over Bluetooth: ( reader . connectionsOverBluetooth ) " ) Kode ini tidak memerlukan API pribadi, tetapi menggunakan string kode keras yang dapat berubah dalam versi OS di masa depan.
print ( " Wifi is Enabled : ( NetworkManager . wifiEnabled ( ) ) " )
print ( " Wifi is Connected : ( NetworkManager . wifiConnected ( ) ) " )
