ios - 从警报启动设置

Question

我想从如下所示的警报中启动设置应用程序:

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{
NSString * title = [alertView buttonTitleAtIndex:buttonIndex];

if([title isEqualToString:@"Ok"])
{
    NSLog(@"Ok was selected.");
}
else if([title isEqualToString:@"Safari"])
{
    NSLog(@"open Safari was selected.");
      [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]];
}

}

我使用了prefs:root = General，但是随后我从下面的链接中阅读...

iOS Launching Settings -> Restrictions URL Scheme

...这在ios5.1中是不可能的。实际上，它在模拟器中不起作用。我能做什么？？谢谢您的帮助

尝试以下操作(适用于iOS 5及更高版本):

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];
