一、配置高德或百度的后台定位框架和代码(略)。
二、配置app不被系统kill，定时获取地理位置信息，并上传服务器(AppDelegate里面)。
具体代码：
1、
- (void)applicationDidEnterBackground:(UIApplication *)application {
//控制定时器不被kill
UIApplication * app = [UIApplication sharedApplication];
__block UIBackgroundTaskIdentifier bgTask;
bgTask = [app beginBackgroundTaskWithExpirationHandler:^{
dispatch_async(dispatch_get_main_queue(), ^{
if (bgTask != UIBackgroundTaskInvalid) {
bgTask = UIBackgroundTaskInvalid;
}
});
}];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
dispatch_async(dispatch_get_main_queue(), ^{
if (bgTask != UIBackgroundTaskInvalid) {
bgTask = UIBackgroundTaskInvalid ;
}
});
});
}
2、
{
//全局计时器
NSTimer * timer;
}
-(void)turnOnTimer{
//14400.0 秒调用一次
timer = [NSTimer scheduledTimerWithTimeInterval:14400.0 target:self selector:@selector(pushGPSdata) userInfo:nil repeats:YES];
[[NSRunLoop currentRunLoop] addTimer:timer forMode:NSRunLoopCommonModes];
}
3、
-(void)pushGPSdata{
//_dicUrl 全局保存定位信息
NSString * cityName = [NSString stringWithFormat:@"%@",_dicUrl[@"cityName"]];
NSString * latitude = [NSString stringWithFormat:@"%@",_dicUrl[@"latitude"]];
NSString * longitude = [NSString stringWithFormat:@"%@",_dicUrl[@"longitude"]];
if (cityName.length !=0&&latitude.length !=0&&longitude.length !=0) {
[self pushGPS:_dicUrl];
}
}
-(void)pushGPS:(NSMutableDictionary*)dic{
[com afPostRequestWithUrlString:trail_Url parms:dic finishedBlock:^(id responseObj) {
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObj options:NSJSONReadingMutableLeaves error:nil];
NSLog(@"%@",dic[@"message"]);
NSString * userStatus = [NSString stringWithFormat:@"%@",dic[@"success"]];
if ([userStatus isEqualToString:@"1"]) {
NSLog(@"GPS成功");
}else{
NSLog(@"GPS失败");
}
} failedBlock:^(NSString *errorMsg) {
}];
}
