的iOS didEnterRegion从来没有所谓

我有一些问题与iOS和gefencing ...的iOS didEnterRegion从来没有所谓

// 
// ViewController.m 
//

#import "ViewController.h" 

@interface ViewController()<CLLocationManagerDelegate> 

{ 
    CLLocationManager *locationManager; 
    CLRegion *testRegion; 
} 
#define METERS_PER_MILE 1609.344 
@end 

@implementation ViewController 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    [self initlocationManager]; 
// [self startlocationManager]; 
} 

// init location Manager Object, set delegation, result and accurate 
- (void)initlocationManager { 
    //create location manager object 
    locationManager = [[CLLocationManager alloc]init]; 

    //this instance send its messages to our AppDelegate 
    [locationManager setDelegate:self]; 

    //to get all results from the location manager 
    [locationManager setDistanceFilter:kCLDistanceFilterNone]; 

    //be accurate as possible 
    [locationManager setDesiredAccuracy:kCLLocationAccuracyBest]; 
} 

- (void)viewWillAppear:(BOOL)animated { 

    CLLocationCoordinate2D startLocation; 
    startLocation.latitude = +52.53753000; 
    startLocation.longitude= +13.35971000; 

    MKPointAnnotation *newLocation = [[MKPointAnnotation alloc] init]; 
    newLocation.coordinate = startLocation; 
    newLocation.title = @"great title"; 
    newLocation.subtitle = @"great subtitle"; 
    MKCoordinateRegion startingRegion = MKCoordinateRegionMakeWithDistance(startLocation,                    0.5*METERS_PER_MILE, 0.5*METERS_PER_MILE); 
    testRegion = [[CLRegion alloc] initCircularRegionWithCenter:startLocation radius:500 identifier:@"TEST"]; 
    [_mapView addAnnotation:newLocation]; 
    [_mapView setRegion:startingRegion animated:YES]; 
    [locationManager startMonitoringForRegion:testRegion]; 
    NSLog(@"%@",locationManager.monitoredRegions); 
} 
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error { 
    NSLog(@"Error : %@",error); 
} 

- (void)locationManager:(CLLocationManager *)manager monitoringDidFailForRegion:(CLRegion *)region withError:(NSError *)error 
{ 
    NSLog(@"Region monitoring failed with error: %@", [error localizedDescription]); 
} 

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region { 
    NSLog(@"Entered Region - %@", region.identifier); 
// [self showRegionAlert:@"Entering Region" forRegion:testRegion.identifier]; 
} 

- (void)locationManager:(CLLocationManager *)manager didStartMonitoringForRegion:(CLRegion *)region { 
    NSLog(@"Started monitoring %@ region", region.identifier); 
} 
- (void)didReceiveMemoryWarning 
{ 
    [super didReceiveMemoryWarning]; 
    // Dispose of any resources that can be recreated. 
} 
@end

的终端给我下面的消息：

2013-05-15 00:24:47.739 [8712:13d03] {(
    (identifier TEST) <+52.53753000,+13.35972000> radius 500.00m 
)} 
2013-05-15 00:24:47.972 [8712:13d03] Started monitoring TEST region

因此该地区成功创建和监控开始，但didEnterRegion函数从未调用过。

帮助会很棒！

编辑：

目前我使用在iPhone模拟器GPX文件，它工作正常。只有didEnterRegion永远不会被调用。

你现在在那个地方吗？ – GoZoner

我使用simultator和gpx文件。我编辑我的第一篇文章。所以你可以用gps coords看到我的gpx文件。 – Hendrik

是否调用了其他CLLocationManagerDelegate方法？ – GoZoner

你的代码看起来不错。只需确保locationManager保留/强制保留。

使用iPhone模拟器测试您的地区代码。在“调试”菜单上，从“位置”子菜单中选择一个位置。更改不同的位置将执行您的代码。

我刚刚使用iPhone模拟器测试了您的代码，并从子菜单中选择了位置。我为'自定义位置'输入了代码的经纬度数字。这里是输出：

2013-05-15 07:42:50.885 Location[69277:c07] {(
    (identifier home) <+37.26917400,-119.30660700> radius 100.00m 
)} 
2013-05-15 07:42:50.932 Location[69277:c07] Started monitoring TEST region 
2013-05-15 07:44:01.103 Location[69277:c07] Entered Region - TEST 
2013-05-15 07:44:59.573 Location[69277:c07] Entered Region - TEST

当我选择'自定义位置'时，'进入的区域'输出发生。我对你的代码所做的唯一修改是：1）将'mapView'行和2）声明为ViewController接口，如下所示。你曾使用类扩展。

@interface ViewController : UIViewController 
    <CLLocationManagerDelegate> 
{ 
    CLLocationManager *locationManager; 
    CLRegion *testRegion; 
} 
@end

确保位置服务为您的应用程序启用。

你是对的。它工作，如果我改变该地区。所以问题一定是gpx文件而不是代码。我创建一个新的，并希望它会在那之后工作.. – Hendrik

加票（当你可以）和复选标记？ – GoZoner

+1，这是一些如何帮助我理解的东西，谢谢 – mAc

确保您设置了委托。你可以通过使用gpx文件模拟移动。包含新文件 - >资源 - > GPX文件。然后，只需编辑文件象下面这样：

<?xml version="1.0"?> 
<gpx version="1.1" creator="Xcode"> 
    <wpt lat="LAT1" lon="LONG1"> 
     <name>Location</name> 
    </wpt> 
    <wpt lat="LAT2" lon="LONG2"> 
     <name>Location</name> 
    </wpt> 
    <wpt lat="LAT3" lon="LONG3"> 
     <name>Location</name> 
    </wpt> 
    <wpt lat="LAT4" lon="LONG4"> 
     <name>Location</name> 
    </wpt> 
    <wpt lat="LAT5" lon="LONG5"> 
     <name>Location</name> 
    </wpt> 
    <wpt lat="LAT6" lon="LONG6"> 
     <name>Location</name> 
    </wpt> 
    <wpt lat="LAT7" lon="LONG7"> 
     <name>Location</name> 
    </wpt> 
    <wpt lat="LAT8" lon="LONG8"> 
     <name>Location</name> 
    </wpt> 
    <wpt lat="LAT9" lon="LONG9"> 
     <name>Cupertino</name> 
    </wpt> 
    <wpt lat="LAT10" lon="LONG10"> 
     <name>Location</name> 
    </wpt> 

    <wpt lat="LAT11" lon="LONG11"> 
     <name>Location</name> 
    </wpt> 

</gpx>

尝试包括里面的坐标和区域之外

现在你可以添加在iPhone模拟器这个文件调试 - >位置 - >自定义位置
