ios - CBCentralManager not detecting nearby devices -

-

CBCentralManager does not detect nearby Bluetooth devices. 

  - (zero) viewDidoadload {[Super Viewedload]; _centralManager = [[CBCentralManager alloc] initWithDelegate: self queue: zero]; _data = [[NSMUtableData Allok] Init]; } - (Zero) Central ManagerED update: (CBC Central Manager) Central {if (central .state == CBCEntertainmentPoideon) {NSDictionary * options = @ {CBCentralManagerScanOptionAllowDuplicatesKey: @NO}; [_centralManager scanForPeripherals with services: zero option: option]; NSLog (@ "Scanning Started"); } If (central.state == CBCentralManagerStateUnknown) {NSLog (@ "CBCentralManagerStateUnknown"); } If (CentralStat == CBCEntryManagerState Resetting) {NSLog (@ "C CB Central Manager Setting"); } If (central .state == CBCentralManagerStateUnsupported) {NSLog (@ "CBCentralManagerStateUnsupported"); } If (CentralStat == CBCEnmentalManagerState unauthorized) {NSLog (@ "CBCEntrealManagerStateUnited"); } If (CentralStat == CBCEnmentalGeneratePoideOff) {NSLog (@ "CBCEnTermNestAstertPaidOf"); }}

I have checked that state CBCentralManagerStatePoweredOn

after that it does not call representative's methods.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all.
