ios - Objective C substite method trigger name with string -

i've got array contains name of function , parameter looks this.

(     [0] => (         [0] => @"getname"         [1] => @"this name"     ) ) 

and method, looks this.

-(nsstring *)getname:(nsstring *)name {...} 

i know trigger method have [[appdelegate alloc] getname:string]; there way substitute getname array[0][0] , string array[0][1]?

here's working example of @chiquis idea. (note selector needs trailing colon):

-(void)dosomethingalittledangerous     nsarray *array = @[@[@"getname", @"this name"]];      nsstring *notquitetheselectorstr = array[0][0];     nsstring *selectorstr = [notquitetheselectorstr stringbyappendingstring:@":"];      sel selector = nsselectorfromstring(selectorstr);      // generates warning because compiler cannot confirm     // self implements programmatically derived selector     if ([self respondstoselector:selector]) {         nsstring *name = [self performselector:selector withobject:array];     }     nslog(@"%@", name); }  - (nsstring *)getname:(nsarray *)array {     return array[0][1]; }
