在ios 7中提出并驳回模态

我有一个视图控制器上有一个按钮.该按钮是隐私政策.当它被点击它去适当的IBAction并且我创建隐私控制器.

- IBAction ...
{
    PrivacyPolicyViewController *privacy = [[PrivacyPolicyViewController alloc] init];
    .....
}

我想创建一个隐私控制器的模态视图,该视图具有一个UIWebView,它可以自动向上弹出,并在ios 7中关闭它的后退按钮.我在线看到的方式都是ios 6,似乎已被弃用.

解决方法

使用这样的东西：

// assuming your controller has identifier "privacy" in the Storyboard
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
PrivacyPolicyViewController *privacy = (PrivacyPolicyViewController*)[storyboard instantiateViewControllerWithIdentifier:@"privacy"];

// present
[self presentViewController:privacy animated:YES completion:nil];

// dismiss
[self dismissViewControllerAnimated:YES completion:nil];
