Iam致力于定位服务，希望从定位服务中获得帮助，我拥有所有所需的属性，例如纬度，经度等，但我也想查找方向（标题）
(void)locationUpdate:(CLLocation *)location {
locationLable.text = [location description];
CLLocationCoordinate2D coordinate = [location coordinate];
NSLog(@"This is location %@",[location description]);
NSLog(@"Lattitude = %@",[NSString stringWithFormat:@"%f", coordinate.latitude]);
NSLog(@"Langitude = %@",[NSString stringWithFormat:@"%f", coordinate.longitude]);
NSLog(@"Altitude = %@",[NSString stringWithFormat:@"%gm", location.altitude]);
NSLog(@"horizontalAccuracy = %@",[NSString stringWithFormat:@"%gm", location.horizontalAccuracy]);
NSLog(@"verticalAccuracy = %@",[NSString stringWithFormat:@"%gm", location.verticalAccuracy]);
NSLog(@"Speed = %@",[NSString stringWithFormat:@"%gm", location.speed]);
}
- (void)headingUpdate:(CLHeading *)heading {
NSLog(@"This is heading %@",[heading description]);
}
- (void)viewDidLoad {
locationController = [[MyCLController alloc] init];
locationController.delegate = self;
[locationController.locationManager startUpdatingLocation];
[locationController.locationManager startUpdatingHeading];
}
我找到了从CLHeading获取它的一些线索，但是仍然无法从CLHeading获取它。我正在使用上面的代码
最佳答案
阅读http://developer.apple.com/library/ios/#DOCUMENTATION/CoreLocation/Reference/CLHeading_Class/Reference/Reference.html :)
我想您应该使用trueHeading。
trueHeading
相对于真北的航向（以度为单位）。 （只读）
@property（只读，非原子）CLLocationDirection trueHeading
关于iphone - Objective-C:如何从定位服务中找到航向(方向)？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/6910443/
