To The Apples Core
1.0.0
Al núcleo de la manzana, sirve como una casa para probar los límites de lo que se puede hacer en iOS nativos sin un jailbreak.
Este proyecto es para fines educativos y el código no debe usarse en ninguna aplicación dirigida a la App Store.
Todos los proyectos y fragmentos están hechos y se ejecutan en dispositivos que no son de Jailbreak . Si bien no se probó, la mayoría de los siguientes fragmentos deberían poder correr en parques infantiles en 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 ] ] ? {
guard case let handle = dlopen ( " /System/Library/PrivateFrameworks/BatteryCenter.framework/BatteryCenter " , RTLD_LAZY ) , handle != nil ,
let c = NSClassFromString ( " BCBatteryDeviceController " ) as AnyObject as? NSObjectProtocol else {
return nil
}
func sharedInstance ( ) -> String { return " sharedInstance " } // Silence compiler warnings
guard c . responds ( to : Selector ( sharedInstance ( ) ) ) == true else { return nil }
let instance = c . perform ( Selector ( sharedInstance ( ) ) ) . takeUnretainedValue ( )
guard let batteries = instance . value ( forKey : " connectedDevices " ) as? [ AnyObject ] else { return nil }
let batteryInfo = batteries . compactMap { battery -> [ String : AnyObject ] ? in
var propertyCount : UInt32 = 0
guard let properties = class_copyPropertyList ( battery . classForCoder , & propertyCount ) else { return nil }
var batteryDictionary = [ String : AnyObject ] ( )
for i in 0 ..< propertyCount {
let cPropertyName = property_getName ( properties [ Int ( i ) ] )
let pName = String ( cString : cPropertyName )
batteryDictionary [ pName ] = battery . value ( forKey : pName ) as AnyObject
}
free ( properties ) //release Obj-C property structs
return batteryDictionary

return batteryInfo
}
print ( " Batteries' Info: ( deviceBatteryInfo ( ) ) " ) 
He creado un proyecto completo en torno a esta idea llamada AppExplorer. Consulte el repositorio para obtener más información y cómo puede implementarlo en su propio proyecto.
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 ( ) ) " ) Para utilizar las funciones de SCDYNAMICSTOREATE y SCDYNAMICSTORECOPYVALUE, deberán cambiar las macro __OSX_AVAILABLE_STARTING para estas funciones.
La forma más fácil de hacer esto es ⌘ + ⌥ + CLICK en los nombres de funciones en Xcode que lo llevarán a los encabezados respectivos. Comenta las macros como se ve aquí:
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 ) " ) Este código no requiere API privadas, pero utiliza cadenas codificadas que pueden cambiar en futuras versiones del sistema operativo.
