第一次 MKReverseGeocoder: didFailWithError:Error Domain=NSURLEr

问题描述

在我的应用程序中，reverseGeocoder 的结果类似于下面的错误块:

In my application at first time reverseGeocoder results like error block below :

didFailWithError:错误Domain=NSURLErrorDomain Code=-1011 "无法执行该操作完全的.(NSURLErrorDomain 错误 -1011.)UserInfo=0x6252100{PBHTTPStatusCode=503}

didFailWithError:Error Domain=NSURLErrorDomain Code=-1011 "The operation couldn’t be completed. (NSURLErrorDomain error -1011.)" UserInfo=0x6252100 {PBHTTPStatusCode=503}

这是我使用的代码:

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { 

     geocoder = [[MKReverseGeocoder alloc] initWithCoordinate:newLocation.coordinate];
     [geocoder setDelegate:self];
     [geocoder start];
    [locationManager stopUpdatingLocation];
}   
-(void)reverseGeocoder:(MKReverseGeocoder *)geocoder1 didFailWithError:(NSError *)error
{
    UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"iBeen There" message:@"GPS can't track the location please check the internet connection." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
    [alert release];
    NSLog(@"reverseGeocoder:%@ didFailWithError:%@", geocoder, error);
}

第一次进入错误块(有时).我有什么遗漏吗，请帮帮我?

The first time its going to error block (some times). Am I missing any thing please help me out?

推荐答案

Error -1011 is Bad Server Response (来自 apple docs here) 并且 HTTP 状态码是 503(服务不可用).

Error -1011 is Bad Server Response (from the apple docs here) and the HTTP status code is 503 (Service Unavailable).

所以，我想除非你给他们无效的数据，否则他们的结局是个问题！

So, I guess that unless you're giving them invalid data, it's a problem their end!

但是，您可能会考虑检查一些极端情况:

However, there are a few edge cases that you might consider checking :

(1)坐标的值是多少?如果它无效，那么地理编码器可能会返回某种错误(尽管它可能不应该返回 503 ；)

(1) What's the value of coordinate? If it's invalid then the geocoder probably returns some sort of error (though it probably shouldn't return 503 ;)

(2) 您是否支持代理/网络身份验证 - 如果您支持，那么您实际上并不是在与地理编码服务对话，而是在与可能无法理解您要做什么的代理对话！

(2) Are you behind a proxy / web authentication - if you are then you're not actually talking to a geocoding service, you're talking to a proxy which probably won't understand what you're trying to do!
