在我的iPhone应用程序,我有一个MapView,我尝试使用为什么kCLErrorNetwork不被调用?
(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
方法来查看用户是否启用位置服务,同时,如果有互联网连接。
在我的.m我这样做:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
_locationManager = [[CLLocationManager alloc] init];
_locationManager.delegate = self;
[_locationManager startUpdatingLocation];
}
return self;
}
这:
- (void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error{
[manager stopUpdatingLocation];
NSLog(@"didFailWithError: %@\n\n\n", error);
switch ([error code]) {
case kCLErrorNetwork:{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"please check your internet connection or that you are not in airplane mode" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alert show];
}
break;
case kCLErrorDenied:{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"enable location services to see your current position." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alert show];
}
break;
default:{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Unknown network error" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alert show];
}
break;
}
}
如果用户不允许应用程序使用位置服务,他会得到正确的“kCLErrorDenied”弹出。另一方面,如果从我的电脑(我使用iPhone模拟器)的以太网电缆被删除,我不会得到kCLErrorNetwork错误。
难道是在iPhone模拟器上,即使没有互联网连接,wifi始终启用? 它还能做什么?
