Nsuserdefaults is used to store user settings

Nsuserdefaults can be used to store user settings.ProgramIt is much easier to read directly than to store files and databases.

Nsstring * const int_hall_filter_speed = @ "inthallfilterspeed ";

Nsstring * const int_hall_filter_seatcount = @ "inthallfilterseatcount ";

Nsstring * const bool_hall_filter_hidefulldesk = @ "boolhallfilterhidefulldesk ";

1. Storage

// Set the default filter settings in the hall
[[Nsuserdefaults standarduserdefaults] setinteger:-1 forkey: int_hall_filter_speed];

[[Nsuserdefaults standarduserdefaults] setinteger:-1 forkey: int_hall_filter_seatcount];

[[Nsuserdefaults standarduserdefaults] setbool: Yes forkey: bool_hall_filter_hidefulldesk];

[[Nsuserdefaults standarduserdefaults] synchronize];

Remember to callSynchronize function.

2. Read

// Initialize filter options
-(Void) initfilterssetting
{
// Read the default filter settings

Nsinteger nsintspeed = [[nsuserdefaults standarduserdefaults] integerforkey: int_hall_filter_speed];

Nsinteger nsseatcount = [[nsuserdefaults standarduserdefaults] integerforkey: int_hall_filter_seatcount];

Bool nsbool = [[nsuserdefaults standarduserdefaults] boolforkey: bool_hall_filter_hidefulldesk];
