终端给我以下消息：
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
因此该区域已成功创建，监控也开始了
但didEnterRegion函数从未调用过。
帮助会很棒！
编辑：
目前我在iphone模拟器中使用该gpx文件，它工作正常。只有didEnterRegion永远不会被调用。

您的代码看起来很好。只需确保locationManager被保留/强烈保留。
使用iPhone模拟器测试您的区域代码。在＆＃39;调试＆＃39;菜单从“位置”选择了一个位置。子菜单。更改不同的位置将会运用您的代码。
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。我输入了代码的自定义位置＆＃39;的纬度/长数字。这是输出：
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
进入的地区＆＃39;当我选择“自定义位置”时发生输出。我对您的代码所做的唯一更改是：1）注释了“mapView”＆＃39;行和2）声明了ViewController接口，如下所示。您使用了类扩展。
@interface ViewController : UIViewController
<CLLocationManagerDelegate>
{
CLLocationManager *locationManager;
CLRegion *testRegion;
}
@end
确保为您的应用启用了位置服务。

确保设置委托。 您可以使用gpx文件模拟移动。 包含新文件 - ＆gt;资源 - ＆gt; GPX文件。然后只需编辑如下文件：
<?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>
尝试包含区域内外的坐标
现在您可以在iphone模拟器中添加此文件Debug-＆gt; location-＆gt;自定义位置
