【中文标题】iBeacon App 有时只能工作,在 iPhone 5 上传输从不工作【英文标题】:iBeacon App only working sometimes, transmitting never working on iPhone 5 【发布时间】:2014-05-18 12:38:42 【问题描述】:我在这里遇到了一个非常奇怪的问题。我正在尝试构建一个应用程序来检测信标。我还没有任何真正的信标,所以我正在使用 iPhone 5 和 iPad 3 进行测试。奇怪的是,传输只能在 iPad 上工作,即使我使用了 iPhone 也不能作为发射器工作相同的应用程序。
但即使使用 iPad 作为发射器,该应用程序也只能在某些时候工作 - 有时 iPhone 会通知我它找到了信标,有时却没有。我已经强制关闭了 iPad 上的应用程序,重新启动后它可以工作,但又一次没有。 由于一切都在零星地工作,我认为它不可能是导致这种行为的代码,但它可能是 - 我不是一个经验丰富的编码器,我刚刚开始这样做。我的代码基于本教程http://www.devfright.com/ibeacons-tutorial-ios-7-clbeaconregion-clbeacon/
我最初认为this 可能是答案,但并没有解决它:它有时仍然有效,有时却无效。
谁能告诉我我在和她打交道吗?
这是我的 Tracker 代码:
ladBeaconTracker.h
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#import <CoreBluetooth/CoreBluetooth.h>
@interface ladBeaconTracker : UIViewController <CLLocationManagerDelegate>
@property (strong, nonatomic) CLBeaconRegion *beaconRegion;
@property (strong, nonatomic) CLLocationManager *locationManager;
@property (weak, nonatomic) IBOutlet UILabel *beaconFoundLabel;
@end
ladBeaconTracker.m
#import "ladBeaconTracker.h"
@interface ladBeaconTracker ()
@property NSUUID *uuid;
@end
@implementation ladBeaconTracker
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
// Custom initialization
return self;
- (void)viewDidLoad
[super viewDidLoad];
// Do any additional setup after loading the view.
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
[self initRegion];
- (void)initRegion
NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:@"A5456D78-C85B-44C6-9F20-8268FD25EF8A"];
self.beaconRegion = [[CLBeaconRegion alloc]initWithProximityUUID:uuid identifier:@"Museum"];
[self.locationManager startMonitoringForRegion:self.beaconRegion];
NSLog(@"Region %@ initated", _beaconRegion.identifier);
- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region
[self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
self.beaconRegion.notifyEntryStateOnDisplay = YES;
NSLog(@"Region %@ entered", _beaconRegion.identifier);
- (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region
[self.locationManager stopRangingBeaconsInRegion:self.beaconRegion];
NSLog(@"Region %@ exit", _beaconRegion.identifier);
- (void)locationManager:(CLLocationManager *)manager didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region
CLBeacon *beacon = [[CLBeacon alloc] init];
beacon= [beacons lastObject];
self.beaconFoundLabel.text =@"Yes";
NSLog(@"Ranged Region %@", _beaconRegion.identifier );
- (void)didReceiveMemoryWarning
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
/*
#pragma mark - Navigation

*/
@end
这是发射器代码:
configViewController.h
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#import <CoreBluetooth/CoreBluetooth.h>
@interface ConfigViewController : UIViewController <CBPeripheralManagerDelegate>
@property (strong,nonatomic) CLBeaconRegion *beaconRegion;
@property(strong,nonatomic) NSDictionary *beaconPeripheralData;
@property (strong, nonatomic) CBPeripheralManager *PeripheralManager;
@end
ConfigViewController.m
#import "ConfigViewController.h"
@interface ConfigViewController ()
@end
@implementation ConfigViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
// Custom initialization
return self;
- (void)viewDidLoad
[super viewDidLoad];
// Do any additional setup after loading the view.
[self initBeacon];
- (void) peripheralManagerDidUpdateState:(CBPeripheralManager *)peripheral
if (peripheral.state == CBPeripheralManagerStatePoweredOn)
NSLog(@"Powered ON");
[self.PeripheralManager startAdvertising:self.beaconPeripheralData];
else if (peripheral.state == CBPeripheralManagerStatePoweredOff)
NSLog(@"Powered OFF");
[self.PeripheralManager stopAdvertising];
- (void)initBeacon
NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:@"A5456D78-C85B-44C6-9F20-8268FD25EF8A"];
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uuid
major:1
minor:1
identifier:@"Museum"];
- (IBAction)transmitBeacon:(UIButton *)sender
self.beaconPeripheralData = [self.beaconRegion peripheralDataWithMeasuredPower:nil];
self.PeripheralManager = [[CBPeripheralManager alloc]initWithDelegate:self queue:nil options:nil];
- (void)didReceiveMemoryWarning
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.

【问题讨论】:
【参考方案1】:您的代码看起来很适合在后台检测信标。两个建议:
我怀疑 iPad 传输时的问题不是 iPad 而是 iPhone 无法接收。尝试重启 iPhone 以清除 known bug in iOS 7.1.
如果您在设置监控的同时设置测距,iOS 可以更快地在前台检测 iBeacons。将[self.locationManager startRangingBeaconsInRegion:self.beaconRegion];
移动到initRegion
并完全取出stopRangingBeaconsInRegion
。
完成 (2) 后,在前台重复测试并查找日志语句 Ranged Region
。当信标打开时,您应该每秒都能看到这一点。
在后台,知道it can take up to 15 minutes 既检测到 iBeacon 又检测到 iBeacon 不再存在。同样,请注意您的日志行以获取有关当前状态的提示,并知道在您第一次获得区域退出事件或重新启动手机之前,您无法获得新的区域进入事件。
【讨论】:
同时调用监控和测距确实有助于更快地检测信标。我现在还获得了三个 Estimote Beacon 用于测试目的,并且这两个设备都可以接收通知。因此,我仍然认为 iPad 是问题所在。尽管如此,它现在正在工作,所以感谢您提供有关测距和监控的提示。以上是关于iBeacon App 有时只能工作,在 iPhone 5 上传输从不工作的主要内容,如果未能解决你的问题,请参考以下文章
