iOS下radiobutton如何保存选中状态，并且在下次启动app时默认

[ericshen880412]

有没有大佬可以指教下，如何在ios下保存radiobutton的选中状态，并且在下次启动app时默认该选项选中

- (void)viewDidLoad {
    [super viewDidLoad];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    self.RadioButton1.selected = [defaults boolForKey:@"radiobutton"];
    self.RadioButton2.selected = [defaults boolForKey:@"radiobutton"];
    self.RadioButton3.selected = [defaults boolForKey:@"radiobutton"];
    [self.RadioButton1 addTarget:self action:@selector(RadioButton1) forControlEvents:(UIControlEventValueChanged)];
    [self.view addSubview:self.RadioButton1];
    // Do any additional setup after loading the view.
}


- (IBAction)onRadioBtn:(RadioButton *)sender {
    _statusLabel.text = [NSString stringWithFormat:@"%@",sender.titleLabel.text];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    BOOL isSelected=[[NSUserDefaults standardUserDefaults]boolForKey:@"radiobutton"];
    isSelected=!isSelected;
    [defaults setBool:sender.selected forKey:@"radiobutton"];
   [defaults synchronize];
}

@end

如果是多个button都需要记录是否为选中状态的话，就需要每个button都对应一个key进行保存记录了
