iphone - Implicit declaration of function 'sqlite3_key'? -


i working on sqlite file encryption. have added sqlcipher & crypto frameworks in project.

now when try compile application on line

int rc = sqlite3_key(database, [key utf8string], strlen([key utf8string]));

it says implicit declaration of function 'sqlite3_key'

so above line "implicit declaration" sounds me function defined not declared. have declared ?

while searching on internet, under article, says sqlite encryption extension(see) not available publically. have purchase of cost around $2000.

see -> http://www.hwaci.com/sw/sqlite/see.html

so reason getting implicit declaration & false response while sqlite encryption process ?

yes, reason getting compiler warning. function sqlite3_key() not defined in version of libsqlite3 included ios. adding in function declaration isn't going help-- fix compiler warning, mean you'll linker error since function isn't defined anywhere.

if purchased see build own copy of sqlite, embed in app, , not use system's libsqlite3. mean you'd have "yes" when app store submission process asks if app includes encryption, meaning paperwork , time before submit app. i'm not whether there's clear indication of whether apple accept then-- would, they've been known surprise people.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
