iOS UIAlertView button to go to Setting App
提问by M Jesse
Is there a way to have the button of a UIAlertView go to the Settings App for the specific App calling it?
有没有办法让 UIAlertView 的按钮转到调用它的特定应用程序的设置应用程序？
Thanks
谢谢

Opening settings apps programmatically is possible only from iOS 8. So, use the following code...
只有在 iOS 8 中才能以编程方式打开设置应用程序。因此，请使用以下代码...
if([CLLocationManager locationServicesEnabled]&&
[CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied)
{
//...Location service is enabled
}
else
{
if([[[UIDevice currentDevice] systemVersion] floatValue]<8.0)
{
UIAlertView* curr1=[[UIAlertView alloc] initWithTitle:@"This app does not have access to Location service" message:@"You can enable access in Settings->Privacy->Location->Location Services" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[curr1 show];
}
else
{
UIAlertView* curr2=[[UIAlertView alloc] initWithTitle:@"This app does not have access to Location service" message:@"You can enable access in Settings->Privacy->Location->Location Services" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"Settings", nil];
curr2.tag=121;
[curr2 show];
}
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(@"buttonIndex:%d",buttonIndex);
if (alertView.tag == 121 && buttonIndex == 1)
{
//code for opening settings app in iOS 8
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
}
}

Apparently, this does not work in iOS 5.1 whatsoever. I have been fighting it all morning, and then ran across this blog
显然，这在 iOS 5.1 中不起作用。一上午都在和它抗争，然后跑到这个博客上

It works on iOS8+ also,but we need to change something
它也适用于 iOS8+，但我们需要改变一些东西
NSURL*url=[NSURL URLWithString:@"prefs:root=WIFI"];
if([[UIApplication sharedApplication] canOpenURL:url]){
[[UIApplication sharedApplication] openURL:url];
}
