Here's a countries plist that I created for this purpose:

Implementation should be pretty straightforward, but here's a bit of our code:

- (id)init {
    if ((self = [super init])) {
        self.countries = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Countries" ofType:@"plist"]];
    }
    return self;
}

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
    self.currentCountry = [[self.countries objectAtIndex:row] objectForKey:@"code"];
    self.countryLabel.text = [[self.countries objectAtIndex:row] objectForKey:@"name"];
}

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
    return self.countries.count;
}

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
    return [[self.countries objectAtIndex:row] objectForKey:@"name"];
}

You can get a list of available country names like this:

self.countryArray = [NSMutableArray new];
for (NSString *countryCode in [NSLocale ISOCountryCodes]) {
    NSString *country = [[NSLocale systemLocale] displayNameForKey:NSLocaleCountryCode value:countryCode];
    [self.countryArray addObject: country];
}

and here are some UIPicker delegate methods:

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
    self.countryLabel.text = [self.countryArray objectAtIndex:row];
}

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
    return self.countryArray.count;
}

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
    return [self.countryArray objectAtIndex:row];
}
