objective c - get UDID of IOS device programmatically? -

-

this question has answer here:

i want udid of ios device programmatically. using following code udid of ios device.

nsuuid *uuid = [nsuuid uuid]; nsstring *uuidstring = uuid.uuidstring;

but output different actual udid of device.

nsstring* identifier = [[[uidevice currentdevice] identifierforvendor] uuidstring]; // ios 6+   nslog(@"output : %@", identifier);

swift 2.x (here x denote above version 2.0)

let identifier: string = uidevice.currentdevice().identifierforvendor().uuidstring() nslog("output : %@", identifier)

swift3

let identifier = uidevice.current.identifierforvendor?.uuidstring      nslog("output : %@", identifier! string)

additional reference

apple apparently starting remove access udid (unique device identifier) in ios5. in event, best can identification purposes use uuid (universally unique identifier). has on per-app basis. is, there no way identify device longer, can identify app on device.as long user doesn’t delete app, identifier persist between app launches, , @ least let identify same user using particular app on device. unfortunately, if user deletes , reinstalls app id change, best can going forward.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
