Key/Value saving to a lot of keys effectively

I am using key/value method to save integer to NSUserDefaults. I have like 30 different cases in a switch and case where each case saves an integer value to a specific key. And I have created one method for each integer that is being saved. Heres some code to explain:

-(void) saveInteger1:(NSInteger)int1 {
    [[NSUserDefaults standardUserDefaults] setInteger:int1 forKey:@"Integer1"];
}
-(void) saveInteger2:(NSInteger)int2 {
    [[NSUserDefaults standardUserDefaults] setInteger:int2 forKey:@"Integer2"];
}
-(void) saveInteger3:(NSInteger)int3 {
    [[NSUserDefaults standardUserDefaults] setInteger:int3 forKey:@"Integer3"];
}
//And I got from 1-30 of these methods

switch (newInteger) {
    case 1:
    [self saveInteger1:newInteger];
    break;
    case 2:
    [self saveInteger2:newInteger];
    break;
    case 3:
    [self saveInteger3:newInteger];
    break;
//And from 1-30 cases
}

What is a more effectively way to do this so it won't be so many lines of code?

Are all of the keys of the form IntegerX? If so then do:

- (void)saveInteger:(NSInteger)value {
    NSString *key = [NSString stringWithFormat:@"Integer%d", value];
    [[NSUserDefaults standardUserDefaults] setInteger:value forKey:key];
}

[self saveInteger:newInteger];

No switch statement is required.
