objective c - initialization makes pointer from integer without a cast -

okay, having hard time this. i've searched past hour on , don't doing wrong. i'm trying take currenttitle of sender, convert integer can use in call list.

nsstring *str = [sender currenttitle]; nsinteger *nt = [str integervalue]; // error appears // nsstring *nextscreen = [nsstring stringwithformat:@"screen_%@.jpg", [screenlist objectatindex:nt]]; 

i assume it's [str integervalue] bit not being used, can't find example works.

thanks!

let's analyze error message:

initialization (nsinteger nt) makes pointer (*) integer ([str integervalue]) without cast.

this means trying assign variable of non-pointer type ([str integervalue], returns nsinteger) variable of pointer type. (nsinteger *).

get rid of * after nsinteger , should okay:

nsstring *str = [sender currenttitle]; nsinteger nt = [str integervalue]; // error appears // nsstring *nextscreen = [nsstring stringwithformat:@"screen_%@.jpg", [screenlist objectatindex:nt]]; 

nsinteger type wrapper machine-dependent integral data type, defined so:

#if __lp64__ || (target_os_embedded && !target_os_iphone) || target_os_win32 || ns_build_32_like_64 typedef long nsinteger; typedef unsigned long nsuinteger; #else typedef int nsinteger; typedef unsigned int nsuinteger; #endif
