我有一个位置获取代码,我想将它放入一个IBAction,但它有很多 - (VOID)。我如何使用相同的代码,但将其放入一个IBAction。将VOID代码转换为IBAction
这里是动作:
Ø
这是我希望把它的代码:
@synthesize locationManager, delegate;
BOOL didUpdate = NO;
- (void)startUpdates
{
NSLog(@"Starting Location Updates");
if (locationManager == nil)
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
// You have some options here, though higher accuracy takes longer to resolve.
locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
[locationManager startUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Your location could not be determined." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alert show];
[alert release];
}
// Delegate method from the CLLocationManagerDelegate protocol.
- (void)locationManager:(CLLocationManager *)manage didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
if (didUpdate)
return;
didUpdate = YES;
// Disable future updates to save power.
[locationManager stopUpdatingLocation];
// let our delegate know we're done
[delegate newPhysicalLocation:newLocation];
}
- (void)dealloc
{
[locationManager release];
[super dealloc];
}
@end
