ios - Getting Error when trying to set a string equal to a part of an NSDictionary -


i'm trying set nsstring token json data when make post request. error i'm getting no visible @interface 'viewcontroller' declares selector 'appname'. i'm initializing userauthtoken in appdelegate acts global variable since want use userauthtoken in multiple classes.

line of code:

[[self appname] userauthtoken:jsondata[@"token"]];

method appname (it's in same file code above):

+ (appdelegate*)appname {     return (appdelegate*) [[uiapplication sharedapplication] delegate]; }

here's in of projects now. create new file called "definitions.h"

in .pch file inside project:

#import "definitions.h"

inside definitions.h

//definitions.h #define appdelegate() (appdelegate *)[[uiapplication sharedapplication]delegate]

now, anywhere in code, can this:

appdelegate *del = appdelegate(); [del userauthtoken:jsondata[@"token"];
