Question

这是关于我谈论的功能

- (void)getAddressFromLatLon:(double)pdblLatitude withLongitude:    (double)pdblLongitude
            {
                NSDictionary *adressWithLtLn = @{ 
                    @"latitude":[NSNumber numberWithDouble:pdblLatitude],
                    @"longtitude":[NSNumber numberWithDouble:pdbllongtitude]};
              [[NSNotificationCenter defaultCenter]postNotificationName:@"userAddress" object:adressWithLtLn];
        }

监听器：

- (void)didGetAddressNotification:(NSNotification*)notification {
    if ([notification object]!=nil){
    NSDictionary *nott = [notification object];
    if( nott!=NULL ){
         currentAddress=nott;
    }
   }}

行动按钮

 - (IBAction)pressButtonOrder:(id)sender {
            if ([currentAddress count]>0){
                 Order *order = [[Order alloc]init];
                [order sendOrder:[currentAddress objectForKey:@"latitude"] source_lng:[currentAddress objectForKey:@"longtitude"]];
             }
            }

和发件人

 -(void)sendOrder:(NSNumber*)source_lat source_lng:(NSNumber*)source_lng;
        {
            API *api=[[API alloc]init] ;

            NSDictionary *params = @{
                                     @"imei":[api getUDID] ,
                                     @"source_lat":source_lat,
                                     @"source_lng":source_lng
                                     };


            AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
            manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

            [manager POST:@"http://" parameters:params
                      success:
                  ^(AFHTTPRequestOperation *operation, id responseObject)
             {
              // some code…    

             }


                  failure:^(AFHTTPRequestOperation *operation, NSError *error)
             {
                  NSLog(@"Error JSON: %@", error);
                   }
             ];
            }

如果值为：


    pdblLatitude=  48.514266999999997
    pdblLongitude= 32.256956000000002

结果我有：

FORM/POST PARAMETERS

    source_lat: 48.514267
    source_lng: 32.256956

错字：

<!-- BEGIN .item -->
    <div id="fullBanner" class="item contain" 
       style="background-image: url('{{ 'slider-item-4.jpg' | asset_url }}'); 
       background-size: contain !important;">   

    <!-- END .item -->
    </div>

你想存储经度不是你......

编辑：这不包括截断方面，但是您显示的结果是字符串，因此您尚未公开的值会发生其他情况。

为什么NSNumber会截断双值？
