I wanted to know how to save the position of a switch to close and open the application ?
-(IBAction)switch_poids_passagers:(UISwitch *)sender {
NSString *poids_passagers_total;
if(sender.on) {
poids_passagers_total = #"1";
} else {
poids_passagers_total = #"2";
}
[[NSUserDefaults standardUserDefaults] setObject:poids_passagers_total forKey:#"poids_passagers_total"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
NSUserDefaults can save and retrieve BOOLS with a pair methods it provides:
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:self.myUISwitch.on forKey:#"switchValue"];
// ...
Later on, maybe in viewWillAppear...
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
BOOL switchValue = [defaults boolForKey:#"switchValue"];
self.myUISwitch.on = switchValue;

Can anyone give me any link or file, which could be used globally for a project to Store data to NSUserDefault.
Which contains method to save dictionary, array,string,integer all.

NSUserDefaults
I have a main page having 3 textfield in my first view as i navigate to different view and return back to my first view (i.e after i enter all the values i moving to next page).I want my 3 textfield to retain its value when i go back to my main page here my sample code :
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *mobile = MobileNum.text;
[defaults setObject:mobile forKey:self.MobileNum.text];
NSString *amountText = amount.text;
[defaults setObject:amountText forKey:self.amount.text];
[defaults synchronize];
NSString *temp = [defaults objectForKey:self.MobileNum.text];
NSString *temp1 = [defaults objectForKey:self.amount.text];
NSLog(#"%# %#",temp,temp1);
at you viewWillDisappear method store the defaults like.
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *mobile = MobileNum.text;
[defaults setObject:mobile forKey:#"mobileNumber"];
NSString *amountText = amount.text;
[defaults setObject:amountText forKey:#"amount"];
[defaults synchronize];
again at your viewWillAppear method retrieve the values like.
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if ([[defaults valueForKey:#"mobileNumber"] length]>0){
MobileNum.text=[defaults valueForKey:#"mobileNumber"];
}
else {
MobileNum.text=#"";
}
if ([[defaults valueForKey:#"amount"] length]>0) {
amount.text=[defaults valueForKey:#"amount"];
}
else {
amount.text=#"";
}
it will work.
I'm trying to make an appointment form on the iPad and I'm having trouble with the UISwitch, I need to save its state and the later load it on another page, I have done this for a text field and a date picker but for some reason it doesn't work for the UISwitch. I am very new to this so any help would be appreciated.
-(IBAction)savedata:(id)sender; {
NSString *savestring = _NameofResident.text;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:savestring forKey:#"savedstring"];
[defaults synchronize];
NSString *savestring1 = _NameofStudent.text;
NSUserDefaults *defaults1 = [NSUserDefaults standardUserDefaults];
[defaults1 setObject:savestring1 forKey:#"savedstring1"];
[defaults synchronize];
NSString *savestring2 = _AppointmentTime.date;
NSUserDefaults *defaults2 = [NSUserDefaults standardUserDefaults];
[defaults2 setObject:savestring2 forKey:#"savedstring2"];
[defaults synchronize];
NSString *savestring3 = _NextAppointmentTime.date;
NSUserDefaults *defaults3 = [NSUserDefaults standardUserDefaults];
[defaults3 setObject:savestring3 forKey:#"savedstring3"];
[defaults synchronize];
NSString *savestring4 = _Confirmed.text;
NSUserDefaults *defaults4 = [NSUserDefaults standardUserDefaults];
[defaults4 setObject:savestring4 forKey:#"savedstring4"];
[defaults synchronize];
}
- (IBAction)loaddata:(id)sender; {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *loadstring = [defaults objectForKey:#"savedstring"];
[_NameofResident setText:loadstring];
NSString *loadstring1 = [defaults objectForKey:#"savedstring1"];
[_NameofStudent setText:loadstring1];
NSString *loadstring2 = [defaults objectForKey:#"savedstring2"];
[_AppointmentTime setDate:loadstring2];
NSString *loadstring3 = [defaults objectForKey:#"savedstring3"];
[_NextAppointmentTime setDate:loadstring3];
NSString *loadstring4 = [defaults objectForKey:#"savedstring4"];
[_Confirmed setText:loadstring4];
}
As you can see I can both load and save the state for the names and times but I don't really know how I can add in a UISwitch to do this.
thanks for your help.
To store the value of a UISwitch state, which is a BOOL, you can do 2 things :
store the BOOL in an NSNumber ([NSNumber numberWithBool:myBool]) and save it with defaults setObject: method. But then, when retrieving the BOOL, you will have to do [defaults objectForKey:#"myKey"].boolValue
store the BOOL itself with defaults setBool:forKey method. And retrieve it with defaults boolForKey method.
Moreover, I've seen you get the defaults many times and synchronize it many times. This is not necessary so I give you an example of what you could have done :
-(IBAction)savedata:(id)sender; {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *savestring = _NameofResident.text;
[defaults setObject:savestring forKey:#"savedstring"];
NSString *savestring1 = _NameofStudent.text;
[defaults setObject:savestring1 forKey:#"savedstring1"];
NSString *savestring2 = _AppointmentTime.date;
[defaults setObject:savestring2 forKey:#"savedstring2"];
NSString *savestring3 = _NextAppointmentTime.date;
[defaults setObject:savestring3 forKey:#"savedstring3"];
NSString *savestring4 = _Confirmed.text;
[defaults setObject:savestring4 forKey:#"savedstring4"];
BOOL savebool5 = _Switch.isOn;
[defaults setBool:savebool5 forKey:#"savedbool5"];
[defaults synchronize];
}
- (IBAction)loaddata:(id)sender; {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *loadstring = [defaults objectForKey:#"savedstring"];
[_NameofResident setText:loadstring];
NSString *loadstring1 = [defaults objectForKey:#"savedstring1"];
[_NameofStudent setText:loadstring1];
NSString *loadstring2 = [defaults objectForKey:#"savedstring2"];
[_AppointmentTime setDate:loadstring2];
NSString *loadstring3 = [defaults objectForKey:#"savedstring3"];
[_NextAppointmentTime setDate:loadstring3];
NSString *loadstring4 = [defaults objectForKey:#"savedstring4"];
[_Confirmed setText:loadstring4];
BOOL loadBool5 = [defaults boolForKey:#"savedbool5"];
[_Switch setOn:loadBool5];
}
You can solve your problem the following way:
//
// ViewController.m
//
#import "ViewController.h"
#interface ViewController ()
#property (weak, nonatomic) IBOutlet UISwitch *mySwitch;
- (IBAction)switchChanged:(id)sender;
#end
#implementation ViewController
- (IBAction)switchChanged:(id)sender
{
[[NSUserDefaults standardUserDefaults] setBool:self.mySwitch.on forKey:#"SwitchState"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.mySwitch.on = [[NSUserDefaults standardUserDefaults] boolForKey:#"SwitchState"];
}
#end
Happy programming !
defaults = [NSUserDefaults standardUserDefaults];
NSLog(#"%#",[defaults objectForKey:#"firsttime"])
if([[defaults objectForKey:#"firsttime"]isEqualToString:#"YES"])
{
UISwitch *onoff = (UISwitch *) sender;
if(onoff.on)
{
NSLog(#"yes on1 facebookswitch");
facebookSwitch.on = YES;
[userDefault setValue:#"true" forKey:#"facebooknotify"];
NSLog(#"on");
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
[validate alertCommonWithoutMessage:NSLocalizedString(#"val_message",nil) :NSLocalizedString(#"val_facebook_login",nil) :#"OK"];
facebookSwitch.on = YES;
NSLog(#"yes on2 facebookswitch");
}
else {
NSLog(#"val_facebook_conf");
[validate alertCommonWithoutMessage:NSLocalizedString(#"val_message",nil) :NSLocalizedString(#"val_facebook_conf",nil) :#"OK"];
facebookSwitch.on = NO;
[userDefault setValue:#"false" forKey:#"facebooknotify"];
NSLog(#"yes off1 facebookswitch");
I'm using this method,but sumtimes the response is null.
Try this code:
// add this code in your switch touch event
- (IBAction)YourSwitch:(UISwitch*)sender
{
if (UISwitch.on)
{
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:true forKey:#"Sound"];
[defaults synchronize];
}
else
{
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:false forKey:#"Sound"];
[defaults synchronize];
}
}
// add this code in your viewDidload .
BOOL isSound= [[NSUserDefaults standardUserDefaults] objectForKey:#"Sound"];
if (isSound){
_ref_slider.on=TRUE;
} else {
_ref_slider.on=FALSE;
}
i hope this code is useful for you.
As to why it's not working, the most common problem is [userDefault synchronize]
Also, rather than using string boolean values, why not use:
[userDefault setBool:YES forKey:#"facebooknotify"];
and then access by
BOOL notified = [userDefault boolForKey:#"facebooknotify"];
- (IBAction)Save:(id)sender {

Im trying to attach the new label i made on storyboard to attach to theTask method. So when the user types in a task and pushes save the task is placed in a list of other tasks
