ios - SecItemAdd not prompting for Touch ID -

-

i have odd problem secitemadd() seems vary between ios 8 , 9. ios 8, saving secure enclave prompt touch id authentication (unless have specified ksecusenoauthenticationui @yes). expect. however, on ios 9, never seem touch id authentication on secitemadd.

i realize between 8 , 9 there change attributes, , ksecusenoauthenticationui deprecated in favour of ksecuseauthenticationui, regardless of whether omit ksecuseauthenticationui, or specify @yes, never prompted.

what should secitemadd() do?

here code snippet of attempting:

cferrorref error = null;     secaccesscontrolref sacobject;      sacobject = secaccesscontrolcreatewithflags(kcfallocatordefault,          ksecattraccessiblewhenpasscodesetthisdeviceonly,          ksecaccesscontroluserpresence, &error);      nsdictionary *attributes =     @{       (__bridge id)ksecclass: (__bridge id)ksecclassgenericpassword,       (__bridge id)ksecattrservice: @"zenbanx",       (__bridge id)ksecattraccount: tokenkey,       (__bridge id)ksecvaluedata: [tokenvalue datausingencoding:nsutf8stringencoding],       /       (__bridge id)ksecusenoauthenticationui: @no,       (__bridge id)ksecuseauthenticationui: @yes,       (__bridge id)ksecattraccesscontrol: (__bridge_transfer id)sacobject       };      osstatus status = secitemadd((__bridge cfdictionaryref) attributes, nil);

my goal have code presents same user interaction between ios 8 , 9.

thanks, in advance.

ksecuseauthenticationui takes ksecuseauthenticationuiallow, ksecuseauthenticationuifail , ksecuseauthenticationuiskip. in case should use ksecuseauthenticationuiallow.
