objective c - Storing SegmentedControl Segment State in NSUserDefaults -

i trying store segment index of segmentedcontrol in nsuserdefaults.

here code loading preferences , preferences 'save' button.

- (void)viewdidload { [super viewdidload]; // stored info before view loads nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults]; int yprefsegment = [defaults integerforkey:@"ypref"]; prefysegmentedcontrol.selectedsegmentindex = yprefsegment; } - (ibaction)saveprefbutton:(id)sender { int ypref = [[prefysegmentedcontrol.selectedsegmentindex] integervalue]; nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults]; [defaults synchronize]; nslog(@"data saved"); }

i getting error on line (in saveprefbutton) :

int ypref = [[prefysegmentedcontrol.selectedsegmentindex] integervalue];

error is: expected identifier

i lost here. don't know talking about.

thank you.

you have 1 syntax error , 2 semantical errors.

the syntax error:

[prefysegmentedcontrol.selectedsegmentindex]

choose 1 of method phone call or dot notation accessing properties. utilize either

[prefysegmentedcontrol selectedsegmentindex]

or

prefysegmentedcontrol.selectedsegmentindex

the first semantical error:

prefysegmentedcontrol.selectedsegmentindex

is integer. no need phone call integervalue on it. (you can't send messages primitive types anyway. not smalltalk.)

the sec semantical error: don't store index in nsuserdefaults. insert

[defaults setinteger:ypref forkey:@"ypref"];

before synchronize user defaults.
