your initialization method wrong. read implementing initializer - handling initialization failure @ ...

- (id)initaspi {   self = [super init];   if ( self ) {     // initialization code   }   return self; } 

why work in viewdidload , not in initaspi?

prescribinginfowebview nil unless you're doing obscure elsewhere.

you're creating prescribinginfowebview in loadview method or automatically initialized during view load if you're loading view xib.
