Ios 位置服务未请求许可

我有件奇怪的事

修复：我在viewDidLoad方法中创建了我的CLLocationManager，因此ARC几乎立即对其进行了清理。我将实例改为类实例而不是方法实例，问题就解决了。

    - (void)viewDidLoad
{
    [super viewDidLoad];
    //Grab the JSON from dcJSONParser
    NSURL *mainContentURL = [NSURL URLWithString:@"http://www.andrewlarking.co.uk/DigiCons/appContent.txt"];
    dcJSONParser *mainJSONParser = [[dcJSONParser alloc]init];
    NSDictionary *mainPageDictonary = [mainJSONParser getContentFromNSURL:mainContentURL];
    //Grab the data from a specific JSON collection
    NSArray *pageOneContent = mainPageDictonary[@"firstRunPage"];
    for ( NSDictionary *pageOne in pageOneContent )
    {
        //Set the label
        self.dcEventDayViewControllerBeaconNameLabel.text = pageOne[@"title"];
    }

    NSLog(@"Event Day View Loaded");

    // Do any additional setup after loading the view.
    //  Start listening for events from the beacon manager.
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFindMint:) name:@"didLocateMint" object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFindBlue:) name:@"didLocateBlue" object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFindPurple:) name:@"didLocatePurple" object:nil];

    //Set Up the beacon manager
    dcBeaconManager *beaconManager = [[dcBeaconManager alloc]init];
    [beaconManager initBeaconManager];
}

更新：调用位置服务的视图直接显示在下面。允许位置服务的请求弹出，然后立即消失。

    - (void)viewDidLoad
{
    [super viewDidLoad];
    //Grab the JSON from dcJSONParser
    NSURL *mainContentURL = [NSURL URLWithString:@"http://www.andrewlarking.co.uk/DigiCons/appContent.txt"];
    dcJSONParser *mainJSONParser = [[dcJSONParser alloc]init];
    NSDictionary *mainPageDictonary = [mainJSONParser getContentFromNSURL:mainContentURL];
    //Grab the data from a specific JSON collection
    NSArray *pageOneContent = mainPageDictonary[@"firstRunPage"];
    for ( NSDictionary *pageOne in pageOneContent )
    {
        //Set the label
        self.dcEventDayViewControllerBeaconNameLabel.text = pageOne[@"title"];
    }

    NSLog(@"Event Day View Loaded");

    // Do any additional setup after loading the view.
    //  Start listening for events from the beacon manager.
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFindMint:) name:@"didLocateMint" object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFindBlue:) name:@"didLocateBlue" object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFindPurple:) name:@"didLocatePurple" object:nil];

    //Set Up the beacon manager
    dcBeaconManager *beaconManager = [[dcBeaconManager alloc]init];
    [beaconManager initBeaconManager];
}

我正在使用CLLocationServices，但我的应用程序未请求使用位置服务的权限。它将显示在列表中，默认情况下处于禁用状态。我已经读到权限存储在设备上，这可能解释了我以前测试过这个应用程序，但是在新设备上测试会得到相同的结果

我不会直接使用位置服务，在决定调用使用位置服务的视图之前，应用程序会经过一些检查和测量。当它这样做时，代码如下：

-(void)initBeacons {
   dcBeaconManager *beaconManager = [[dcBeaconManager alloc]init]; //Create an instance of the dcBeaconManager class.
    [beaconManager initBeaconManager];  //Start the beacon manager running.
}

调用的类是：

#import "dcBeaconManager.h"

@implementation dcBeaconManager

-(id)init
{
    self = [super init];
    if (self != nil){}
    return self;
}

bool testRanging = true;
bool firstRegionEntered = true;

- (void)initBeaconManager {
    NSLog(@"initBeaconManager called");
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;
    NSUUID *uuid = [[NSUUID alloc]initWithUUIDString:@"B9407F30-F5F8-466E-AFF9-25556B57FE6D"];
    self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid identifier:@"digiConsRegion"];
    [self.locationManager startMonitoringForRegion:self.beaconRegion];
}

- (void)stopBeaconManager {
    [self.locationManager stopMonitoringForRegion:self.beaconRegion];
}

- (void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region {
    NSLog(@"Started looking for regions");
    [self.locationManager requestStateForRegion:self.beaconRegion];
}

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
    NSLog(@"Region discovered");
    if (firstRegionEntered) {
        NSLog(@"First time in region");
        firstRegionEntered = false;
    }
    [self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
}

- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
    NSLog(@"Region left");
    [self.locationManager stopRangingBeaconsInRegion:self.beaconRegion];

    UILocalNotification *notification = [[UILocalNotification alloc] init];
    notification.alertBody = @"We hope you enjoyed the event, thank you for coming.";
    notification.soundName = UILocalNotificationDefaultSoundName;
    [[UIApplication sharedApplication] presentLocalNotificationNow:notification];
}

- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region {
    NSLog(@"locationManager initiated");
    CLBeacon *beacon = [[CLBeacon alloc] init];
    beacon = [beacons lastObject];
    //Store some information about this beacon
    NSNumber *currentBeaconMajor = beacon.major;  //it's major (group) number
    NSNumber *currentBeaconMinor = beacon.minor;  //it's minor (individual) number

    if (([currentBeaconMinor floatValue] == 59204) && ([currentBeaconMajor floatValue] == 33995) && (beacon.proximity == CLProximityNear)) {
        NSLog(@"Mint discovered");
        [[NSNotificationCenter defaultCenter] postNotificationName:@"didLocateMint" object:nil];
    } else if (([currentBeaconMinor floatValue] == 7451) && ([currentBeaconMajor floatValue] == 63627) && (beacon.proximity == CLProximityNear)) {
        NSLog(@"Blue discovered");
        [[NSNotificationCenter defaultCenter] postNotificationName:@"didLocateBlue" object:nil];
    } else if (([currentBeaconMinor floatValue] == 51657) && ([currentBeaconMajor floatValue] == 26976) && (beacon.proximity == CLProximityNear)) {
        NSLog(@"Purple discovered");
        [[NSNotificationCenter defaultCenter] postNotificationName:@"didLocatePurple" object:nil];
    }

}


- (void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region {
    if (testRanging) {
        NSLog(@"Testing: forced ranging");
        if ([region isEqual:self.beaconRegion] && state == CLRegionStateInside) {
            [_locationManager startRangingBeaconsInRegion:(CLBeaconRegion *)region];
        }
    }
}

@end

没有一个委托方法被调用，Malloc最初想知道位置服务，所以我环顾四周，发现了上面的特殊错误

有什么想法吗？我很高兴分享整个项目

干杯。

您的应用程序是否列在隐私设置的“位置服务”下？默认情况下是关闭的。如果该应用程序列在隐私设置中，则用户已被询问。每个应用程序只会请求一次权限，除非您重置所有隐私设置。这是令人困惑的事情，重置隐私设置，重新运行应用程序，没有任何区别。您得到解决方案了吗？我也有类似的问题。在我的情况下，首次使用CLLocationManager不会触发授权请求：let authorizationStatus=CLLocationManager.authorizationStatus（）
