Ios 如何在Theos中为越狱应用程序添加重新启动按钮

要创建restring按钮，我可以编写如下代码：

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [btn setTitle:@"Respring" forState:UIControlStateNormal];
    btn.frame = CGRectMake(100,50,120,100);

    [btn addTarget:self action:@selector(buttonPushed:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn];
}

- (void)buttonPushed:(id)sender

{
    system("killall -9 SpringBoard");
    return;

}

但要使重新启动按钮，它似乎不能这样做。

我应该写什么代码？

尝试这样做：

- (void)buttonPushed:(id)sender

{
    [[UIApplication sharedApplication] reboot];
    return;

}

我在一个示例项目中尝试了这一点，发现效果很好。我将模板的调用替换为

[[UIApplication sharedApplication] relaunchSpringBoard];

与

[[UIApplication sharedApplication] reboot];
