iPhone sdk位置变更通知

Question

我计划在iPhone上进行GPS定位。你能告诉我有关GPS的信息（代表，方法等）。

Answer 1

查找CLLocationManager和CLLocationManagerDelegate的文档。如果您还有具体问题，请回来问问他们。

Answer 2

声明CLLocation的位置管理器

CLLocationManager *locManager;

在你的功能

中

self.locManager = [[CLLocationManager alloc] init]; 
locManager.delegate = self; 
locManager.desiredAccuracy = kCLLocationAccuracyBest;
[locManager startUpdatingLocation];   // This Method will call the didUpdateToLocation Delegate
[locManager stopUpdatingLocation];   //This Methods stops the GPS from updating

位置管理员代表

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
 //Do actions when the GPS is Updating
}
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
    NSLog(@"Error in GPS: %@",error);  
}

不要忘记在.h文件中包含CLLocationManagerDelegate并将CoreLocation Framework添加到项目中
