很难在测试手机上运行地理围栏-IOS

这是我每年在这里的第一篇帖子。呜呼

这是我的故事。。。我花了大约一周的时间尝试IOS中的地理围栏教程。问题是我现在必须在Objective-C中完成

我正试图让一个小应用程序来运行这个地理围栏，但我一直有实际触发事件的问题

我正在我的实际手机（iPhone7plus）上测试它，我无法让一些事件显示在屏幕上，无论我在该地区还是在外地

我将粘贴.h和.m文件中的代码。到目前为止，我只实施了这些措施

#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>

@interface ViewController : UIViewController <CLLocationManagerDelegate>
@property (weak, nonatomic) IBOutlet UILabel *myLat;
@property (weak, nonatomic) IBOutlet UILabel *myLon;
@property (weak, nonatomic) IBOutlet UILabel *destLat;
@property (weak, nonatomic) IBOutlet UILabel *destLon;
@property (weak, nonatomic) IBOutlet UILabel *diff;
@property (weak, nonatomic) IBOutlet UILabel *answer;
@property BOOL alwaysOn;
@property BOOL isCLickOn;

@property (retain, nonatomic) CLLocationManager *locationManager;

@end

发生的情况是，即使应用程序处于打开状态，我的手机上也不会显示任何事件。因此，我在故事板上有一个视图控制器，它应该显示我的位置和目标位置，并显示两个对象之间的距离。但即使我步行400米，然后走回中心，它也不会显示出来

我知道Swift是我应该使用的，我会改用Swift，但现在我真的很想了解地理围栏的过程

任何帮助都将不胜感激。我在编程方面也很新，所以我仍在努力学习和理解Objective-C

多谢各位

大家好，欢迎来到Stack Overflow，请阅读如何创建和检查，以增加获得反馈和有用答案的机会。谢谢。我试试看。我仍在努力适应这一点。
