Question

我收到了网络服务和地理编码的纬度和经度列表，然后获取完整地址。问题是，经过一段时间后，它们变为空，地理编码器停止工作！有人可以帮帮我吗？

以下是我用来获取地址的代码：

-(void)getAddressArray:(void (^)(id response))completion{
for (int i=0; i<[favoritos count]; i++) {

    double latitude = [[[favoritos valueForKey:@"latitude"] objectAtIndex:i] doubleValue];
    double longitude = [[[favoritos valueForKey:@"longitude"] objectAtIndex:i] doubleValue];
    CLLocationCoordinate2D location = CLLocationCoordinate2DMake(latitude, longitude);
    CLLocation * locationAtual = [[CLLocation alloc]initWithLatitude:location.latitude longitude:location.longitude];
    CLGeocoder *geocoder = [[CLGeocoder alloc] init];

    [geocoder reverseGeocodeLocation:locationAtual completionHandler:^(NSArray *placemarks, NSError *error) {
        NSDictionary *dicAddress;

        CLPlacemark *place = [placemarks firstObject];

        if (placemarks) {
            NSLog(@"%@",place.addressDictionary);
            if ([place.addressDictionary valueForKey:@"Thoroughfare"] == [NSNull null] || ![place.addressDictionary valueForKey:@"Thoroughfare"]) {
                dicAddress = @{@"id":[[favoritos objectAtIndex:i] valueForKey:@"id"],@"address":@"Endereço não encontrado!",@"complemento":[[favoritos objectAtIndex:i] valueForKey:@"references"],@"number":[[favoritos valueForKey:@"numero"] objectAtIndex:i],@"name":[[favoritos valueForKey:@"name"] objectAtIndex:i], @"latitude":[[favoritos valueForKey:@"latitude"] objectAtIndex:i], @"longitude":[[favoritos valueForKey:@"longitude"] objectAtIndex:i]};
            }


            [address addObject:dicAddress];

            if ([address count] == [favoritos count])
                completion(address);
        }    
}];
}

谢谢！

检查传入块的错误，可能是您发送了很多请求并达到了速率限制。

reverseGeocodeLocation:completionHandler:

有费率限制

地理编码请求对每个应用都是速率限制的，所以制作太多了短时间内的请求可能会导致一些请求失败。超过最大速率时，地理编码器会传递错误具有值kCLErrorNetwork的对象到您的完成处理程序。

Geocoder在一段时间后返回null
