例如：

NSURL*url=[NSURL URLWithString:@"prefs:root=WIFI"]; 
[[UIApplication sharedApplication] openURL:url];

Answer 2

在iOS5中及以上...

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

Answer 3

显然，这并不在iOS的5.1工作任何。我一直在整个上午的战斗，然后过这个博客跑

Answer 4

打开设置应用程序是只能从iOS版8.因此，使用下面的代码...

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]]; 
} 
} 

Answer 5

它适用于iOS8上+还，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]; 
}
