Core Bluetooth deprecations for iOS 7

由 别来无恙 提交于 2019-12-01 07:20:57
问题 In iOS 7, some Core Bluetooth things are now deprecated like CBUUIDGenericAccessProfileString and CBUUIDDeviceNameString. The apple docs state "(Deprecated. There are no replacements for these constants.)" I am wondering what we are supposed to do to replace these GAP things, as the apple docs and examples are of no help. The entire internet also seems to be silent about this. My code is pretty much just like the Heart Rate Monitor example which still has the deprecated code /* GAP (Generic

I want to trigger iOS7 to ask users permission to use Bluetooth and Twitter account

由 こ雲淡風輕ζ 提交于 2019-12-01 06:49:12
问题 This is somewhat backward to what most people ask. I want to purposely trigger the dialog asking for the users permission to: Connect to bluetooth devices, even when offline. Access there iOS-based Twitter account. I already have a similar dialog for location working fine. I'm doing this because I want to make the process of asking permission a bit more gentle, like Heyday, by showing a welcome screen explaining why the app needs this service then when the user taps OK, initiating the request

CLBeaconRegion, how to turn off warning: Turn On Bluetooth to Allow * to Connect to Accessories

We have a project that is using CoreLocation regions to monitor iBeacon region entering/exiting in the app background. CLBeaconRegion (CLRegion), CLBeacon, etc. CLLocationManager returns callbacks when a CLBeacon (iBeacon) region is entered. It is a light wrapper around a bluetoothManager underneath. // various CLLocation delegate callback examples - (void) locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region; - (void) locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region;

How to control when to present the Bluetooth permission request prompt in iOS13?

由 允我心安 提交于 2019-12-01 05:36:10
问题 With the new policies related to privacy & Bluetooth in iOS13, my app launches an alert prompt on app install, or after app update (in iOS13) requesting access to Bluetooth. Is there anyway to control the presentation of this prompt? I'm making sure that the app doesn't access or initializes anything related to the CBCentralManager, on app start, but in a very specific place in the app, but still I get the prompt on app start. Is the presentation of this prompt related to the CBCentralManager
