Package development of Map location positioning

In many app development often use the positioning function, for this common method is necessary for its encapsulation use

Not much to say directly on the code: the use of a single-case design mode:
`

Import <foundation/foundation.h>import <MapKit/MapKit.h>

@protocol positiontooldelegate <NSObject>

@optional
/**

• Notification value when position changes
  */
  • (void) noticepositionchanged;

@end

@interface positiontool:nsobject<cllocationmanagerdelegate,positiontooldelegate> {
Cllocationmanager _locationmanager;
Nsmutablearray _locationarr;
}

@property (nonatomic,assign) cllocationdegrees latitude;//Longitude
@property (nonatomic,assign) cllocationdegrees longtitude;//latitude
/**

• Location Area Information
  /
  @property (Nonatomic,strong) nsstring positionname;
  @property (nonatomic,strong) nsstring province;
  @property (Nonatomic,strong) nsstring city;
  @property (Nonatomic,strong) NSString *area;

@property (Nonatomic,strong) id<positiontooldelegate> delegate;

/**

• Adding callback proxy methods
  */
  • (void) AddDelegate: (id) delegate;
    /**
• Remove Callback Proxy method
  */
  • (void) Removedelegate: (id) delegate;
    /**
• Get Location Center Information
  */
  • (cllocationcoordinate2d) Getcenter;
    /**
• Update location
  */
  • (void) updateLocation;

• (void) getLocation;

/**

• Single-instance initialization method
  */
  • (Positiontool ) shareinfo;
    /*
• Releasing a single case information
  */
  • (void) Freeinfo;

@end
.m方法的实现

• (positiontool*) Shareinfo {
  @synchronized (self) {

    if (_positionTool == nil) {      _positionTool=[[PositionTool alloc] init];      [email protected]"没有定位"; }

  }
  return _positiontool;
  }
  /**
  • Releasing a singleton implementation
    */

• (void) Freeinfo {
  if (_positiontool) {

    nil;

  }
  }

• (ID) Init {
  Self=[super Init];
  if (self) {

    _locationArr=[[NSMutableArray alloc] init];

  }
  return self;
  }
  /**

  • Proxy callback Add and remove implementation methods
    *
  • @param delegate Agent
    */
• (void) AddDelegate: (id<positiontooldelegate>) Delegate {
  [_locationarr Addobject:delegate];
  }
• (void) Removedelegate: (id) Delegate {
  [_locationarr Removeobject:delegate];
  }

/**

• Get location information
  */

• (cllocationcoordinate2d) Getcenter {
  return [_locationmanager location].coordinate;
  }
• (void) UpdateLocation {
  [_locationmanager startupdatinglocation];
  }pragma Mark ========= Get location ==========
• (void) GetLocation {
  if ([Cllocationmanager locationservicesenabled]) {

    _locationManager=[[CLLocationManager alloc] init];  _locationManager.delegate=self;  //精度最高，耗电最大  _locationManager.desiredAccuracy=kCLLocationAccuracyBest;  _locationManager.distanceFilter = 200; [_locationManager startUpdatingLocation]; if ([[[UIDevice currentDevice] systemVersion] floatValue] >=8.0) { [_locationManager requestAlwaysAuthorization]; }

  }
  }

pragma mark-Call Map Proxy method

• (void) Locationmanager: (Cllocationmanager ) Manager didfailwitherror: (nserror ) Error {
  NSLog (@ "%@", error);
  }

• (void) Locationmanager: (Cllocationmanager *) Manager didchangeauthorizationstatus: (clauthorizationstatus) Status {
  Switch (status) {

    case kCLAuthorizationStatusNotDetermined:      if ([_locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) { [_locationManager requestAlwaysAuthorization]; } break; default: break;

  }
  }
  Get latitude and longitude

  Cllocation Newlocation=locations[0];
  Cllocationcoordinate2d oldcoordinate=newlocation.coordinate;

  }];

  For (id<positiontooldelegate> delegate in _locationarr) {

Use time to add directly to the place where you use it
[[Positiontool Shareinfo] getLocation];
