永远不会调用iOS 8 CLLocationManagerDelegate方法 [英] iOS 8 CLLocationManagerDelegate methods are never called

问题描述

//查看是否加载了方法-分配了LocationManager并将CLLocationManagerDelegate包含在.h文件中

//View did Load Method- LocationManager is allocated and have included the CLLocationManagerDelegate in .h File

-ViewDidLoad{
self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;
    self.locationManager.desiredAccuracy=kCLLocationAccuracyBest;
    self.locationManager.distanceFilter=kCLDistanceFilterNone;
    [self.locationManager requestWhenInUseAuthorization];
    [self.locationManager startMonitoringSignificantLocationChanges];
    [self.locationManager startUpdatingLocation];

}
// Location Manager Delegate Methods
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    NSLog(@"%@", [locations lastObject]);
}

推荐答案

在plist中，您必须添加2个条目

In plist you have to add 2 entries

1. NSLocationWhenInUseUsageDescription


2. NSLocationAlwaysUsageDescription

将两者都设为需要位置才能找到您所在的位置或任何东西

Make the string of both as "Location is required to find out where you are" or anything

self.locationManager = [[CLLocationManager alloc]init];

if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
    [self.locationManager requestWhenInUseAuthorization];
}
self.locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
CLAuthorizationStatus authorizationStatus= [CLLocationManager authorizationStatus];

if (authorizationStatus == kCLAuthorizationStatusAuthorized ||
    authorizationStatus == kCLAuthorizationStatusAuthorizedAlways ||
    authorizationStatus == kCLAuthorizationStatusAuthorizedWhenInUse) {
    NSLog(@"You are authorized");

}

self.locationManager.delegate = self;
[self.locationManager startUpdatingLocation];
