技术分享- IOS后台获取地理位置并且上传到服务器

时间:2022-03-07 17:57:05
有时候需要获取手机的地理位置,当程序关闭的时候,也可以获取地理位置并且上传到服务器端。苹果在后台可以运行的程序,只有三种,一个是声音,一个是获取地理位置。下面主要说一下在后台获取地理位置,并且定时发送到服务器端。
实现非常简单,首先在info.plist中添加属性:
技术分享- IOS后台获取地理位置并且上传到服务器

通过下面的代码获取地理位置:
#import “MyCLController.h”

@implementation  MyCLController

@synthesize  locationManager;
@synthesize  delegate;

- (id) init {
self = [super init];
if (self != nil) {
self.locationManager = [[[CLLocationManager alloc] init] autorelease];
self.locationManager.delegate = self; // send loc updates to myself
}
return self;
}

- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
NSLog(@”dsdsds===>>>%f”,newLocation.coordinate.latitude);
[self.delegate locationUpdate:newLocation];
}


- (void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error
{
[self.delegate locationError:error];
}

- (void)dealloc {
[self.locationManager release];
[super dealloc];
}
@end




在添加一个定时器,就可以定时发送数据。

[NSTimer scheduledTimerWithTimeInterval:(1.0) target:self selector:@selector(onTimer) userInfo:nil repeats:YES];


下面是程序关闭之后运行的日志:
