我想創建一個將獲取位置和地址的NSObject，我也將運行一些其他代碼。我想把它放到我的不同應用程序中。我在更新位置時遇到問題。我有協議和委託工作，但我會發布我的所有代碼，以嘗試清楚。NSObject內的CLLLocationManager
在我getLocation.h
@protocol getLocationDelegate
- (void)getLocation:(NSString *)address getLongitude:(CGFloat)longitude getLatitude:(CGFloat)latitude;
@end
@interface getLocation : NSObject <CLLocationManagerDelegate> {
CGFloat latitude;
CGFloat longitude;
NSString *address;
}
@property (nonatomic, strong) id<getLocationDelegate> delegate;
@property (nonatomic, retain) CLLocationManager *locationManager;
- (void)getLocationInfo;
在我getLocation.m
- (id)init
{
if (self = [super init]) {
self.locationManager = [[CLLocationManager alloc] init];
self.locationManager.delegate = self;
self.locationManager.distanceFilter = kCLDistanceFilterNone; // whenever we move
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;
}
return self;
}
- (void)getLocationInfo {
[self.locationManager startUpdatingLocation];
// This is being called but not starting the locationManager
}
後，我得到的地址和位置，我稱之爲協議這樣的，在我的getLocation.h
[self.delegate getLocation:address getLongitude:longitude getLatitude:latitude];
在我的.m文件中，我想獲取位置，這是代碼
getLocation *location = [[getLocation alloc] init];
[location setDelegate:self];
[location getLocationInfo];
然後，我有我的方法，當委託被調用
-(void)getLocation:(NSString *)address getLongitude:(CGFloat)longitude getLatitude:(CGFloat)latitude {
// Do code after location and address has been returned
}
現在我的協議和委託正在我的問題是什麼，我不能得到的LocationManager開始更新。不知道發生了什麼事。
