NSUserDefaults always returns 0, in Simulator and Device

Question

I have a settings bundle in my iPhone app, with the following PList:

Type: PSMultiValueSpecifier
Title: Within (Kilometres)

DefaultValue: Number: 1
Titles: Array:
    Item 1: Number: 1
    Item 2: Number: 2
Values: Array:
    Item 1: Number: 1
    Item 2: Number: 2
Key: String: km

Then in my code i have:

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];   
NSInteger choiceOne = [defaults integerForKey:@"km"];

choiceOne is always 0.

What am i doing wrong?

Thanks

Answer 1

Have you tried actually start Settings app and select the "Within" settings, then come back to the app to check? The app won't take the default value automatically.

You can check if the key really exists with

NSNumber* obj = [defaults objectForKey:@"km"];
NSInteger choiceOne;
if (obj == nil) {
  choiceOne = 1; 
  [defaults setInteger:choiceOne forKey:@"km"];
} else {
  // check whether obj really implements -integerValue if needed.
  choiceOne = [obj integerValue];
}

Or just set the value to 1 if it's outside of the expected range.
