Question

I am trying to read the values of Root.plist key into NSArray so I can populate a table view for my App settings.

I am using the following code to retrieve the values of the key “country”:

NSArray *arrayCountry = [[NSUserDefaults standardUserDefaults] arrayForKey:@"country"];
NSLog(@"Number of items in array >>>>>> %d", arrayCountry.count);

NSLog returns:

Number of items in array >>>>>> 0

I tried the same on different keys but still get the same result.

Can anyone shed some light on this issue. Did I miss anything here?

Make sure your arrayCountry isn’t nil. If it is, arrayCountry.count will return zero even if it is nil.

Try this:

NSUserDefaults* std = [NSUserDefaults standardUserDefaults];
[std setObject:[NSArray arrayWithObjects:@"US",@"GB",@"CN",nil] forKey:@"country"];
NSArray *arrayCountry = [std arrayForKey:@"country"];
if(arrayCountry == nil){
    NSLog(@"Something's strange in the neighborhood.");
}else{
    NSLog(@"Number of items in array >>>>>> %d", arrayCountry.count);
}
