所以现在我至少会收到以下代码的回调...
- (void)viewDidLoad {
[super viewDidLoad];
mapView=[[MKMapView alloc] initWithFrame:self.view.frame];
//mapView.showsUserLocation=TRUE;
mapView.delegate=self;
[self.view insertSubview:mapView atIndex:0];
NSLog(@"locationServicesEnabled: %@", [CLLocationManager locationServicesEnabled] ? @"YES":@"NO");
CLLocationManager *newLocationManager = [[CLLocationManager alloc] init];
[newLocationManager setDesiredAccuracy:kCLLocationAccuracyBest];
[newLocationManager setDistanceFilter:kCLDistanceFilterNone];
[self setLocationManager:newLocationManager];
[[self locationManager] setDelegate:self];
[[self locationManager] startUpdatingLocation];
NSLog(@"Started updating Location");
}
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
NSLog(@"Did update to location");
mStoreLocationButton.hidden=FALSE;
location=newLocation.coordinate;
MKCoordinateRegion region;
region.center=location;
MKCoordinateSpan span;
span.latitudeDelta=0.01;
span.longitudeDelta=0.01;
region.span=span;
[mapView setRegion:region animated:TRUE];
}
我可以在第二种方法中设置断点，并且NSLog报告连续的位置更新，但是由于某些原因，跨度缩放无法正常工作。知道为什么吗？它有我的座标和所有东西。有点抓我的头。
最佳答案
将CLLocationManager分配给您类的(strong)属性。 (我假设您使用的是ARC BTW。)现在，CLLocationManager并没有超出viewDidLoad方法的末尾，因此也无法调用您的委托(delegate)方法。
关于iphone - CLLocationManager startUpdatingLocation不起作用，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/11697730/
