ios - Dynamic printing of class and function -


i beginner xcode , want dynamic printing of function being executed.

so want function display 

functionexecuted() executed in classname

that grab function name , class name dynamically. have already:

class myviewcontroller: viewcontroller {     func appactivity() {         var class: string = "myviewcontroller"         println("\(___function___) executed in \(class)")     }     override func viewdidload() {         // etc. code         appactivity()     } }

which run appactivity() function when view loaded. have output of:

appactivity() executed in myviewcontroller

when looking for:

viewdidload() executed in myviewcontroller

i want retain not having appactivity take input parameters. also, instead of defining class name explicitly, have dynamically name of class function in.

i know might not best way of accomplishing more learning , understanding.

my recommendation in extension. extensions perhaps highlight of swift, imho. can decorate methods, not of own classes, other classes, including framework classes. want know when viewdidload got called of superclass? create extension , watch messages appear in console.

the other advantages:

  • the code not dirtying main class , logic (whatever is)
  • you define extension in test file it's automatically there when running tests , not @ runtime

the swift cocoa code built on extensions in ways inventive, showing of intelligence of aspects, , yet categorical organization of objective c. when combine extensions , protocols, have traits.

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
