-

getting data nsuserdefaults , passing has parameter application crashed

    nsuserdefaults *prefs = [nsuserdefaults standarduserdefaults];    [logincontroller showview:[prefs objectforkey:ksavedusername] :[prefs objectforkey:ksaveduserpassword]]; //              [logincontroller showview:@"abcd03@gmail.com" password:@"apple”];

when printing value in nslog [prefs objectforkey:ksaveduserpassword] showing value. password , [prefs objectforkey:ksavedusername] user name.

if hard-coded requirement parameters working fine.

my crash log is

unrecognized selector sent instance 0x5ccc2d0 2011-07-21 14:32:27.721 ishop[3815:207] *** terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[loginviewcontroller showview::]: unrecognized selector sent instance 0x5ccc2d0' *** call stack @ first throw:

your logincontroller doesn't respond showview:: message, that's why app crashes. check method name in loginviewcontroller, , correct it. think there no matter nsuserdefaults.
try avoid unamed parameters in selectors, always name them, avoid problems.
