- (instancetype)initWithFilterCriteria:(GCKFilterCriteria *)filterCriteria;

[GoogleCodeExporter]

Initialising scanner wit this method causes the scanner will never find my 
Chromecast device.

GCKFilterCriteria * filterCriteria = [GCKFilterCriteria 
criteriaForAvailableApplicationWithID:@"MY-APP-ID-HERE"];
_scanner = [[GCKDeviceScanner alloc] initWithFilterCriteria:filterCriteria];

string @"MY-APP-ID-HERE" is replaced to my application ID.

If you haven't already done so, you'll need to add a listener and start the 
scan. The following code comes from the iOS sender documentation 
(https://developers.google.com/cast/docs/ios_sender#scan):

//Establish filter criteria
GCKFilterCriteria *filterCriteria = [GCKFilterCriteria 
criteriaForAvailableApplicationWithID:kReceiverAppID];

//Initialize device scanner
self.deviceScanner = [[GCKDeviceScanner alloc] 
initWithFilterCriteria:filterCriteria];
[self.deviceScanner addListener:self];
[self.deviceScanner startScan];

Note that the scanner will show only devices that can run your app. If you 
haven't yet published your sender/receiver to the developer console, it will 
only show up on whitelisted devices.

You can also check out the iOS sample apps on the Googlecast Github page 
(https://github.com/googlecast) for some examples on how to build an iOS 
sender. For any future development issues, please direct your questions to

• Changed state: NotSDK

Our cast device has been published and it's working good with Android SDK.

And it's working good with this method:
_scanner = [[GCKDeviceScanner alloc] init];

but -(instancetype)init; has been deprecated.

Can you implement the GCKLogger delegate and provide the logs from the scan?

That's the standard behavior for NSNetService provided by iOS. Please see the 
"When resolving fails" section at
