ios 實現獲取當前地理位置 – iPhone手機開發技術文章 iPhone軟體開發教學課程

鑌哥主要寫幾個步驟,希望能幫到大傢:

前提導入:CoreLocation.farme

#import

代理

{

//實現獲取當前地理位置:第一步:

//這兩個變量,locationManaager用於獲取位置,checkinLocation用於保存獲取到的位置信息

NSString * currentLatitude;
NSString * currentLongitude;
CLLocationManager *locManager;
CLLocation *checkinLocation;

}

#pragma mark–CLLocationManagerDelegate

/*

第二步:

實現地理位置實現第一個代理方法

運行到這個方法的時候,locationManager已經得到瞭當前的位置,所以在這個方法中應該把獲取到的當前位置保存到變量checkinLocation中*/

– (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation

fromLocation:(CLLocation *)oldLocation {

checkinLocation = newLocation;

//do something else

}

/*

第三步:

在第二步實現的方法其實是被CLLocationManager中的方法startUpdatingLocation調用的,也就是說,當程序運行 locationManager.startUpdatingLocation的時候,第二步實現的方法就會被調用

*/

– (void) setupLocationManager {

locationManager = [[CLLocationManager
alloc]
init] ;

if ([CLLocationManager
locationServicesEnabled]) {

NSLog(
@”Starting CLLocationManager” );

locationManager.delegate =
self;

locationManager.distanceFilter =
200;

locationManager.desiredAccuracy =
kCLLocationAccuracyBest;

[locationManager
startUpdatingLocation];

} else {

NSLog(
@”Cannot Starting CLLocationManager” );

/*self.locationManager.delegate = self;

self.locationManager.distanceFilter = 200;

locationManager.desiredAccuracy = kCLLocationAccuracyBest;

[self.locationManager startUpdatingLocation];*/

}

}
