Load data from NSUserDefaults in ViewDidLoad

Question

In the start screen of my app you are able to choose language between English and Swedish by clicking on either the flag of UK or Sweden. The problem is that the ViewDidLoad does not recognize changes in the NSUserDefaults when you click a button. But when you restart the app, the language is the latest flag you clicked! So it saves the NSUserDefault but it only loads it the first time in ViewDidLoad..

When you click the English flag, sprakval sets to 0, and if you click the swedish flag, sprakval sets to 1. When you click a flag, it changes to a image with a tick icon in front of the flag.

Code:

-(IBAction) sprakEN
 {
    sprakval=0;
    NSUserDefaults *sprakvalet = [NSUserDefaults standardUserDefaults];
    [sprakvalet setInteger:sprakval  forKey:@"Sprak "];
    [sprakvalet synchronize];

    [super viewDidLoad];
}



-(IBAction) sprakSE
 {
     sprakval=1;
     NSUserDefaults *sprakvalet = [NSUserDefaults standardUserDefaults];
     [sprakvalet setInteger:sprakval  forKey:@"Sprak "];
     [sprakvalet synchronize];

      [super viewDidLoad];
 }

  - (void)viewDidLoad
    {
        [super viewDidLoad];

        NSUserDefaults *sprakvalet = [NSUserDefaults standardUserDefaults];
        sprakval2  = [sprakvalet integerForKey:@"Sprak "];

        if (sprakval2==0)
        {
            spraklabel.text = [NSString stringWithFormat:@"Language:"];

            [lhb setTitle:@"english" forState:UIControlStateNormal];
            [hlb setTitle:@"english" forState:UIControlStateNormal];
            [fhb setTitle:@"english." forState:UIControlStateNormal];
            [blandatb setTitle:@"english.." forState:UIControlStateNormal];

            UIImage *encheck = [UIImage imageNamed:@"United_Kingdomchecked.png"];
            [enbutton setImage:encheck forState:UIControlStateNormal];

            UIImage *seuncheck = [UIImage imageNamed:@"Sweden.png"];
            [sebutton setImage:seuncheck forState:UIControlStateNormal];

            self.title = @"Game";
        }
        else if(sprakval2==1)
        {
            spraklabel.text = [NSString stringWithFormat:@"Språk:"];

            [lhb setTitle:@"swedish" forState:UIControlStateNormal];
            [hlb setTitle:@"swedish" forState:UIControlStateNormal];
            [flb setTitle:@"swedish" forState:UIControlStateNormal];
            [fhb setTitle:@"swedish" forState:UIControlStateNormal];
            [blandatb setTitle:@"swedish" forState:UIControlStateNormal];

            self.title = @"Spel";
            UIImage *secheck = [UIImage imageNamed:@"Swedenchecked.png"];
            [sebutton setImage:secheck forState:UIControlStateNormal];

            UIImage *enuncheck = [UIImage imageNamed:@"United_Kingdom.png"];
            [enbutton setImage:enuncheck forState:UIControlStateNormal];
        }

    // Do any additional setup after loading the view, typically from a nib.
     }

Answer 1

This is because you are calling ViewDidload method through its super class in -(IBAction) sprakSE and -(IBAction) sprakEN methods. So replace [super viewDidLoad]; with [self viewDidLoad]; in both methods. It will work properly.

Hope it helps you.
