Answer 1

NSUserDefaults * myNSUserDefaults = [NSUserDefaults standardUserDefaults];
NSDictionary * dict = [myNSUserDefaults dictionaryRepresentation];
for (id key in dict) {

     //heck the keys if u need
     [myNSUserDefaults removeObjectForKey:key];
}
[myNSUserDefaults synchronize];

or

[NSUserDefaults resetStandardUserDefaults];
[NSUserDefaults standardUserDefaults];
