Question

I need to save a slider preference in my Settings.bundle.

I’m using the following code to write to the Settings.bundle:

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setInteger:mySlider.value forKey:@"TimerSliderKey"];
[defaults synchronize];

And the following code to read from the Settings.bundle:

NSUserDefaults *defaults2 = [NSUserDefaults standardUserDefaults];
int valueForSlider = [defaults2 integerForKey:@"TimerSliderKey"];
NSLog(@"The saved slider value is %@" , valueForSlider);

This code does not work. Can someone give me some replacement code that I could use?

Answer 1

Your problem is here:

NSLog(@"The saved slider value is %@" , valueForSlider);

You need to use the %d format specifier, %@ is the format specifier to send the description message to the argument.

NSLog(@"The saved slider value is %d" , valueForSlider);

Here’s a list of format specifiers:
