Question

I have a value that I want to store. By default it is 14. I have a text field that a user would input their own value perhaps 5, 10, or 20. I need that value stored (every time they open the app, too) to be used across 3 different classes.

What’s the best approach? Settings Bundle? Is there an easier way?

Answer 1

You can use NSUserDefaults.

int

[[NSUserDefaults standardDefaults] setObject:[NSNumberNumberWithInt:5] 
                                      forKey:@"kPlus"];

float

[[NSUserDefaults standardDefaults] setObject:[NSNumberNumberWithFloat:5.2] 
                                      forKey:@"kMinus"];

The same method method can be used for double.

[[NSUserDefaults standardDefaults] setDouble:2.1234  
                                      forKey:@"kMultiply"];
