ios - Am I able to use recordID.recordName in a CKQuery? -

ckquery doc says: key names used in predicates correspond fields in evaluated record. key names may include names of record’s metadata properties such "creationdate” or info fields added record.

what else metadata can utilize in ckquery? able utilize record.recordid.recordname, if yes, key it?

yes, create ckquery searching recordid this:

var query = ckquery(recordtype: recordtype, predicate: nspredicate(format: "%k == %@", "creatoruserrecordid" ,ckreference(recordid: thesearchrecordid, action: ckreferenceaction.none)))

where thesearchrecordid recordid.recordname looking for

metadata fields recordid, recordtype, creationdate, creatoruserrecordid, modificationdate, lastmodifieduserrecordid, recordchangetag

c++ - How to initialize linked list whose node is matrix? -

in c++, can initialize linked list nodes matrix? can utilize std::list< double[2][2]> mylist, means every node in linked list 2*2 matrix?

if cannot initialize this, how can accomplish it?

you need wrap matrix in struct or class, e.g.

#include <list> struct d { double a[2][2]; }; int main() { std::list<d> mylist; d d = { 1.0, 2.0, 3.0, 4.0 }; mylist.push_back(d); }

for reason whenver seek compile android studio project, keeps saying image "default" invalid. doesn't create sense because in xml file has no issue displaying when alter view design mode view. after compile, gradle throws issue , "r." turn symbol not found. i.e. whever did r.id.textview, r's turn reddish , can't alter back.

visual studio 2013 - s2013 multi device hybrid apps and deploy to both android emulator and device -

iam tring run in vs2013 multi device hybrid apps , deploy both android emulator , device. maintain getting next errors.

i have added apk , modified environment settings. created emulutor in avd manger

error 14 g:\developement\windowsphone\wp8test\test20\test20\bld\debug\platforms\android\cordova\node_modules\q\q.js:126 test20 error 15 throw e; test20 error 16 ^ test20 error 17 error: failed launch application on device: error: failed install apk device: error: failed deploy device, no devices found. test20

the error appears when not have right set of drivers device installed on machine.

to prepare this, visit:

device-specific oem driver, or

google usb driver google nexus devices

once done, ensure go device manager in settings , update drivers device pointing location of download.

once done, should able deploy device seamlessly.

note: take allow usb debugging if prompted on android device.

*taken official documentation.

json - Override how Data.Aeson handles only one field of my record -

json - Override how Data.Aeson handles only one field of my record -

i making rest api university courses:

data course of study = course of study { id :: maybe text, name :: text, deleted :: bool } deriving(show, generic) instance fromjson course of study instance tojson course of study

i allow deleted optional in serialized json structure, not in application. want set deleted false if isn't specified when parsing.

i write manual instance fromjson, don't want have write out fields. want declare how deleted handled , allow automatic instance handle else.

how this?

to knowledge there not way customize generic instance, construction type bit differently:

data course of study = course of study { courseid :: maybe text -- don't utilize `id`, it's function , name :: text } deriving (show, generic) info deletable = deletable { deleted :: bool , item :: } deriving (show) instance fromjson course of study instance tojson course of study instance fromjson => fromjson (deletable a) parsejson (object v) = <- parsejson (object v) d <- v .:? "deleted" .!= false homecoming $ deletable d parsejson _ = mzero

now can do

> allow nodeleted = "{\"name\":\"math\",\"courseid\":\"12345\"}" :: text > allow withdeleted = "{\"name\":\"math\",\"courseid\":\"12345\",\"deleted\":true}" :: text > decode nodeleted :: maybe (deletable course) (deletable {deleted = false, item = course of study {courseid = "12345", name = "math"}}) > decode nodeleted :: maybe course of study (course {courseid = "12345", name = "math"}) > decode withdeleted :: maybe (deletable course) (deletable {deleted = true, item = course of study {courseid = "12345", name = "math"}}) > decode withdeleted :: maybe course of study (course {courseid = "12345", name = "math"})

and can optionally tag course of study deletable when need it, , fromjson instances take care of everything.

ios - Add button only in Code? -

ios - Add button only in Code? -

i'm trying add together button in code. in xcode simulator works not on device :

fatal error: unexpectedly found nil while unwrapping optional value

my code:

@iboutlet weak var playbutton: uibutton! override func viewdidload() { super.viewdidload() allow image = uiimage(named: "playbutton.png") uiimage playbutton = uibutton.buttonwithtype(uibuttontype.system) uibutton playbutton.frame = cgrectmake(10, 10, 100, 100) // crash here playbutton.center = cgpointmake(self.frame.width/2, self.frame.height/1.7) playbutton.addtarget(self, action: "transition:", forcontrolevents: uicontrolevents.touchupinside) playbutton .setbackgroundimage(image, forstate: uicontrolstate.normal) self.view?.addsubview(playbutton) }

someone can help me?

that makes no sense - if using @iboutlet means button created in storyboard, hence not need initialize it:

let image = uiimage(named: "playbutton.png") uiimage playbutton = uibutton.buttonwithtype(uibuttontype.system) uibutton playbutton.frame = cgrectmake(10, 10, 100, 100) // crash here playbutton.center = cgpointmake(self.frame.width/2, self.frame.height/1.7) playbutton.addtarget(self, action: "transition:", forcontrolevents: uicontrolevents.touchupinside) playbutton .setbackgroundimage(image, forstate: uicontrolstate.normal) self.view?.addsubview(playbutton)

remove of above code , set in storyboard instead. @ibaction should separate method hooked touchupinside of button in storyboard.

ios - iAd enabled app not receiving any requests -

the lastly iad enabled app released started generating requests appeared in app store, did not generate impressions 3-4 days until started receiving ads apple (that behavior normal)

yesterday released iad enabled app , has not generated single request allow lone impression. https://itunes.apple.com/us/app/barograph/id926055907?mt=8

the app not listed kids. app generate test ads when running beta builds before submitting it. apps shows in iad.apple.com dashboard greenish lite , says recieving ads, has not generated single request yet. contracts in itc date.

is there might have done wrong, or have forgotten preventing me getting advertisement requests?

the reply is, appears normal. though apps generate requests immediately, others take few days (in both cases takes few days generate actual impressions). latest app started receiving requests on 24 hours after release date , started generating impressions @ same time. dapp before started generating requests did not impressions 3-4 days.
