Question

我正在创建一个iOS应用，需要连接到“http://xxx.xxx.xx.xxx/WebSiteServices.svc?wsdl”等网络服务。

应用程序允许在选择一些字段后为带行李的旅行报价：

原产国（原产国名单）;
目的地国家/目的地国家/地区列表;
5个行李箱的5个识别字段，每个行李允许选择不同身份证的行李数量。

为了与Web服务进行通信，我进行了SOAP调用，如链接中所述：“iPhone interaction with ASP.NET WebService。”

我成功接收了国家和行李列表，现在我无法将所选数据发送到Web服务以调用“calcolaImporto”（计算金额）方法。我必须发送SOAP消息：

idPaesePrelievo：原籍国的ID（整数：好的，我成功了）;
idPaeseDest：目的地国家/地区的ID（整数：好的，我成功了）;
idProdotti：标识所选存储的ID的整数列表（问题：我无法发送数组）;
qtaProdotti：标识为每个第一个列表选择的行李ID数量的整数列表（问题：我无法发送数组）。

这两个列表没有相互连接，但是我无法将这两个数组发送到Web服务。

Web服务中的数组由两个整数列表组成，即使两个Xcode数组由两个对象id列表组成（我也尝试从id转换为int，但没有）。

访问该方法，但结果为“0”，因为没有检查任何行李：我该怎么办？

请帮助我，谢谢！

下面我发布了“ViewController.m”的代码：

#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
@synthesize amount, idPaeseDest, idPaesePrelievo, idProdotti, qtaProdotti;
/* amount (TEXTFIELD), idPaeseDest (INT), idPaesePrelievo (INT), idProdotti (NSMUTABLEARRAY), qtaProdotti (NSMUTABLEARRAY) */

[super viewDidLoad];
}

Answer 1

你不能用整数列表创建一个NSString并用,分隔它们并发送它吗？

NSMutableString *mutableList = [[NSMutableString alloc ]initWithString:@"<q14:ArrayOfint>"];
//I'll say like this because i don't know if you added them as NSNumber or NSString
for(int i = 0 ;i < idProdotti.count;i++)
{
NSInteger value = [[idProdotti objectAtIndex:i]integerValue];

  [mutableList appendFormat:@"<arr:int>%d</arr:int>",value];

 }
[mutableList appendFormat:@"</q14:ArrayOfint>"];

然后发送mutableList，然后发送release; // qtaProdotti的第二个

NSMutableString *mutableList1 = [[NSMutableString alloc ]initWithString:@"<q15:ArrayOfint>"];
//I'll say like this because i don't know if you added them as NSNumber or NSString
for(int i = 0 ;i < qtaProdotti.count;i++)
{
NSInteger value = [[qtaProdotti objectAtIndex:i]integerValue];

  [mutableList1 appendFormat:@"<arr:int>%d</arr:int>",value];

 }
[mutableList1 appendFormat:@"</q15:ArrayOfint>"];

然后发送mutableList1，然后发送release;

Answer 2

我这样解决了：

我使用了“SoapUI”，一个与Web服务交互的图形界面，我重写了SOAP消息;
我使用了两个类似于向我展示“Soryngod”的列表。

这是正确的代码：

NSMutableString *idLista = [[NSMutableString alloc] init];
for(int i=0; i<idProdotti.count; i++) {
    NSInteger value = [[idProdotti objectAtIndex:i] integerValue];
    [idLista appendFormat:@"<arr:int>%d</arr:int>",value];
}

NSMutableString *qtaLista = [[NSMutableString alloc] init];
for(int i=0; i<qtaProdotti.count; i++) {
    NSInteger value = [[qtaProdotti objectAtIndex:i] integerValue];
    [qtaLista appendFormat:@"<arr:int>%d</arr:int>",value];
}

NSString *soapMsg = [NSString stringWithFormat: @"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
                 "<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/\" xmlns:tem="http://tempuri.org/\" xmlns:arr="http://schemas.microsoft.com/2003/10/Serialization/Arrays\">"
                 "<soapenv:Body>"
                 "<tem:CalcolaImporto>"
                 "<tem:idPaesePrelievo>%d</tem:idPaesePrelievo>"
                 "<tem:idPaeseDest>%d</tem:idPaeseDest>"
                 "<tem:idProdotti>%@</tem:idProdotti>"
                 "<tem:qtaProdotti>%@</tem:qtaProdotti>"
                 "</tem:CalcolaImporto>"
                 "</soapenv:Body>"
                 "</soapenv:Envelope>", idPaesePrelievo, idPaeseDest, idLista, qtaLista];
