永远不会调用iOS 8 CLLocationManagerDelegate方法

Question

  

// View已经分配了Load Method- LocationManager，并且在.h文件中包含了CLLocationManagerDelegate

-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]);
}

Answer 1

在plist中你必须添加2个条目

1. NSLocationWhenInUseUsageDescription
2. NSLocationAlwaysUsageDescription

将两者的字符串设为＆＃34;需要位置以找出您的位置＆＃34;或任何东西

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];

希望这有帮助
