swift - How to get exact user sitting position latitude and longitude values in a room? -

-

i want exact user sitting position latitude , longitude values in room or building. getting user location latitude , longitude values through cllocationmanager not showing. possibility through user exact building latitude , longitude values.

thanks laxman

gps precision @ best 10m, cannot expect obtain positions better precision that, not enough positioning within building. besides, if user not using gps, network-based positioning data has yet lower precision.

i don't think can use cllocationmanager or other out-of-the-box positioning service that.

technologies exist can used locate phone within building based on other sensor data (eg. https://en.situm.es/solutions.php), perhaps apply.

there ways improve gps precision outdoors (eg. https://es.wikipedia.org/wiki/wide_area_augmentation_system) depending on live. depends on application.

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
