ios - display data based on uiswitch state -


i trying display data based on if user has selected switch. user have ability select either 1 or 2 switches either both on or 1 or other on. data displayed according state of switch.

i have managed load displaying data dare array in plist file , dosnt matter state switch in displays dare not truth or both.

- (ibaction)shownext:(id)sender {     if (!self.plistarray) {         nsstring *path = [[nsbundle mainbundle] pathforresource:                           @"data" oftype:@"plist"];           nsuserdefaults *defaults =[nsuserdefaults standarduserdefaults];         if ([[defaults objectforkey:@"truthonoff"] isequaltostring:@"yes"] && [[defaults objectforkey:@"dareonoff"] isequaltostring:@"yes"]  ) {             nsdictionary *plistdict1 = [[nsdictionary alloc] initwithcontentsoffile:path];             nsarray * plistarray1 = plistdict1[@"truth"];             nsdictionary *plistdict2 = [[nsdictionary alloc] initwithcontentsoffile:path];             nsarray *plistarray2 = plistdict2[@"dare"];             self.plistarray = [[plistarray1 arraybyaddingobjectsfromarray:plistarray2] mutablecopy];          } else if ([[defaults objectforkey:@"truthonoff"] isequaltostring:@"yes"] ) {             nsdictionary *plistdict3 = [[nsdictionary alloc] initwithcontentsoffile:path];             nsarray *plistarray3 = plistdict3[@"truth"] ;             self.plistarray = [plistarray3 mutablecopy];             nslog(@"%@", plistarray);         } else ([[defaults objectforkey:@"dareonoff"] isequaltostring:@"yes"] ); {             nsdictionary *plistdict4 = [[nsdictionary alloc] initwithcontentsoffile:path];             nsmutablearray *plistarray4 = plistdict4[@"dare"];             self.plistarray = [plistarray4 mutablecopy];             nslog(@"%@", plistarray);         }     } }     -(void)stateswitched:(id)sender {     uiswitch *tswitch = (uiswitch *)sender;     nsuserdefaults *defaults =[nsuserdefaults standarduserdefaults];     [defaults setobject: tswitch.ison ? @"yes" : @"no" forkey:@"truthonoff"];      [defaults synchronize]; }  -(void)stateswitcheddare:(id)sender {     uiswitch *tswitch = (uiswitch *)sender;     nsuserdefaults *defaults =[nsuserdefaults standarduserdefaults];     [defaults setobject: tswitch.ison ? @"yes" : @"no" forkey:@"dareonoff"];      [defaults synchronize]; }

this code setting object

try use boolforkey instead of objectforkey. , in other hand, why else have condition?:

if ([defaults boolforkey:@"truthonoff"] && [defaults boolforkey:@"dareonoff"]) {      // both true  } else if ([defaults boolforkey:@"truthonoff"] && ![defaults boolforkey:@"dareonoff"]) {      // truthonoff true, dareonoff false } else if (![defaults boolforkey:@"truthonoff"] && [defaults boolforkey:@"dareonoff"]) {      // truthonoff false, dareonoff true } else {      // both false }

make sure 2 things when store boolean values in nsuserstandarddefaults:

  1. use setbool setter: [[nsuserdefaults standarduserdefaults] setbool:yes forkey:@"a_key"];
  2. remember synchronize standarduserdefaults save values.
