我有位置跟踪类和另一个带有列表的类。我需要在输入listView时检查locationService是否正在运行。在locationService类中,我添加了boolean来跟踪服务的启动和停止。但是我无法从listView类中跟踪这个布尔变量。
这是我的代码,我现在正在做什么,但它只需要locationService类的初始值
//listView.m
@property (strong,nonatomic) LocationTracker * trackerClass;
- (void)viewWillAppear:(BOOL)animated{
self.trackerClass = [[LocationTracker alloc] init];
if([self.trackerClass getTrackerStatus]==1)
NSLog(@"LOCATION SERVICE STATUS IS RUNNING");
else
NSLog(@"LOCATION SERVICE STATUS IS STOPPED");
}
//locationService.h
@property (nonatomic, readwrite) int trackerStatus;
- (int)getTrackerStatus;
//locationService.m
- (void)stopLocationTracking {_trackerStatus=0;}
- (void)startLocationTracking {_trackerStatus=1;}
- (int)getTrackerStatus{
return _trackerStatus;
}
提前谢谢你!

尝试将此布尔变量设置为局部变量,并创建一个简单的静态getter来获取此bool。您的LocationTracker将更改变量的值,您可以从任何地方获取它。
@implementation LocationTracker
BOOL isStart;
//Dont forget to delclear this methode in the .h file
+(BOOL)isStart{
return isStart;
}
your code...
您的应用中的任何位置只需导入您的calss和wirte:
BOOL isStart = [LocationTracker isStart];
//The getting vaiable should be the updated bool in you LocationTracker class

尝试删除
- (int)getTrackerStatus{
return _trackerStatus;
}
