几个月前我的代码工作得很好。我知道任何事情
我不明白为什么当我启动应用程序时，Region中的didRangeBeacons不会触发：
#import "ESTViewController.h"
#import "PresentViewController.h"
#import <ESTBeaconManager.h>
#import <Parse/Parse.h>
#import <AudioToolbox/AudioToolbox.h>
@interface ESTViewController () <ESTBeaconManagerDelegate>
@property (nonatomic, strong) ESTBeaconManager* beaconManager;
@property (nonatomic, strong) ESTBeacon* selectedBeacon;
@property (nonatomic, strong) NSArray *beaconsArray;
@end
@implementation ESTViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// setup Estimote beacon manager.
// Create the manager instance.
self.beaconManager = [[ESTBeaconManager alloc] init];
// Setup the delegate
self.beaconManager.delegate = self;
// Avoiding unknown state or not
self.beaconManager.avoidUnknownStateBeacons = NO;
// create sample region object (beacons in this case have all same uuid and same major)
region = [[ESTBeaconRegion alloc] initWithProximityUUID:ESTIMOTE_PROXIMITY_UUID identifier:@"multibeacons"];
[self.beaconManager requestStateForRegion:region];
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
// start looking for estimote beacons in region
// when beacon ranged beaconManager:didRangeBeacons:inRegion: invoked
[self.beaconManager startRangingBeaconsInRegion:region];
[self.beaconManager startMonitoringForRegion:region];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
}
- (void)viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
// stop looking for estimote beacons in region
[self.beaconManager stopRangingBeaconsInRegion:region];
[self.beaconManager stopMonitoringForRegion:region];
}

我在pragma标记后面有一个断点，它永远不会达到该代码。我真的不明白为什么。
感谢您的帮助。
答案 0 :(得分：2)
我找到了解决方案：
我用以下内容更新了Info.plist文件：
<key>NSLocationAlwaysUsageDescription</key>
<string>This application monitors your location to show you promotional offers in shops you're passing by.</string>
在iphone中，我已将我的应用的本地化设置更改为＆＃34;始终＆＃34;
