Question

我想通过以下警告启动设置应用：

- (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，但后来我从下面的链接中读到了......

iOS Launching Settings -> Restrictions URL Scheme

...这在ios5.1中是不可能的。事实上，它在模拟器中不起作用。我能做什么？？谢谢你的帮助

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General&path=Assistant "]];

试试这个（适用于iOS 5及更高版本）：

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