问题描述
针对iOS9的更新:我是iOS的新手,尝试使用CoreLocation返回纬度和经度值。以下代码从不执行日志输出
UPDATED for iOS9: I am new to iOS, experimenting with CoreLocation to return latitude and longitude values. The following code never executes the log output
-(void)viewWillAppear:(BOOL)animated{
manager = [[CLLocationManager alloc]init];
manager.delegate = self;
manager.desiredAccuracy = kCLLocationAccuracyBest;
[manager startUpdatingLocation];
}
这是我的didUpdateToLocation函数,从未达到
Here is my didUpdateToLocation function with is never reached
- (void)locationManager:(CLLocationManager *)manager
didUpdateLocations:(NSArray<CLLocation *> *)locations{
NSLog(@"Location: %@", locations);
CLLocation *currentLocation = locations.lastObject;
if (currentLocation != nil) {
float latitude = currentLocation.coordinate.latitude;
float longitude = currentLocation.coordinate.longitude;
NSLog(@"dLongitude : %f", longitude);
NSLog(@"dLatitude : %f", latitude);
}
else{ NSLog(@"ERROR");
}
}
推荐答案
1。首先,您应该使用应该使用实际设备而不是模拟器
1.first of all, you should use you should use a actual device instead of a simulator
2.implement CLLocationManagerDelegate在界面,例如
2.implement CLLocationManagerDelegate in the interface,like
@interface XXXXX () <CLLocationManagerDelegate>
3。
locationManager = [[CLLocationManager alloc] init];
添加
locationManager.delegate = self;
4。实现委托方法
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray<CLLocation *> *)locations
{
for (CLLocation *location in locations) {
//you can get locations here
}
}
