CLLocationManager没有更新位置

这与我的其他question有关，但是我只打开一个新的iOS标签，因为它可能是问题在原生端。CLLocationManager没有更新位置

问题：位置管理器没有更新位置。我试着阅读locationManager.location，它总是给我一个缓存位置。

然后我修改代码使用CLLocationManagerDelegate和-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {} 永远不会被调用。

我的.h文件：

#import "TiModule.h" 
#import <CoreLocation/CoreLocation.h> 
#import <CoreMotion/CoreMotion.h> 

@interface TiMovementModule : TiModule<CLLocationManagerDelegate> 

@property (nonatomic, retain) CLLocationManager *locationManager; 
@property (nonatomic, readonly) NSDictionary *currentMovement; 

- (void)startMovementUpdates:(id)args; 
- (void)stopMovementUpdates:(id)args; 

@end

答案是位置更新必须从主线程完成。在Titanium中，您只需在函数开头调用ENSURE_UI_THREAD。

你应该尝试把一个断点在这条线：

[self.locationManager startUpdatingLocation];

，看看如果你到达那里代码中没有证据表明它已经被执行。
