Question

我使用Sudzc（ARC分支）解析soap响应时遇到问题。我有一些WCF服务存储我们的应用程序的数据。我设法连接到Web服务我可以成功获得响应，但是当其中一个响应带有z：ref属性时我卡住了。没有一个例子很难解释对吗？ ;）/我用例如“#someid”替换了重要数据，所以不要指出它是一个问题;）

如您所见，有些线路将Receiver节点标识为i2 您还可以看到来自同一发件人和同一接收者的另一条消息的节点

sudzc生成的用于解析此xml的类：

@interface ResultOfGetMessages : SoapObject{
    int _AllItemsCount;
    NSMutableArray* _Items;
    int _PageIndex;
    NSDate* _RetrievedDateTime;
}

@interface Message : WSGlobalObject{
    NSString* _Content;
    NSDate* _CreatedDate;
    NSString* _Priority;
    User* _Receiver;
    User* _Sender;
    NSString* _Topic;
}

@interface User : WSGlobalObject{
    int _CountryId;
    NSDate* _CreationDate;
    NSString* _Gender;
    BOOL _IsDeleted;
    PictureInfo* _Picture;
    NSString* _UserName;
}

使用Touchxml的Sudz无法读取（获取null接收者和发送者），响应被解析为：

<ResultOfGetMessages>
<AllItemsCount>2</AllItemsCount>
<Items>
    <Message>
        <GlobalId>###</GlobalId>
        <Content>bbbbbbbb</Content>
        <CreatedDate>2013-02-14T16:33:07.000</CreatedDate>
        <Priority>Normal</Priority>
        <Receiver>
            <GlobalId>####</GlobalId>
            <CountryId>37</CountryId>
            <CreationDate>2013-01-31T16:12:40.000</CreationDate>
            <Gender>Male</Gender>
            <IsDeleted>false</IsDeleted>
            <Picture i:nil="true" ></Picture>
            <UserName>tobiasz</UserName>

        </Receiver>

我认为问题在于反序列化的深度。解析器（if）尝试获取具有指定id的接收器节点但是它失败，因为标记有此id的接收器节点位于其他节点（前一个项目节点）中。

提前感谢您的帮助和时间。

在序列化节点时，soap.m遇到了类似的问题。不得不这个代码：

// Deserializes the element in a dictionary.
+(id)deserializeAsDictionary:(CXMLNode*)element {

if([element childCount] == 1) {
CXMLNode* child = [[element children] objectAtIndex:0];
if([child kind] == CXMLTextKind) 
{
     NSLog(@"The Child Node: %@", [[[element children] objectAtIndex:0] stringValue]);
    return [[[element children] objectAtIndex:0] stringValue];

}
}

NSMutableDictionary* d = [NSMutableDictionary dictionary];
for(CXMLNode* child in [element children]) {
id v = [Soap deserialize:child];
if(v == nil) { v = [NSNull null]; }
[d setObject:v forKey:[child name]];
}
return d;
}

为：

// Deserializes the element in a dictionary.
+(id)deserializeAsDictionary:(CXMLNode*)element {

if([element childCount] == 1) {
CXMLNode* child = [[element children] objectAtIndex:0];
if([child kind] == CXMLTextKind) 
{
     NSLog(@"The Child Node: %@", [[[element children] objectAtIndex:0] stringValue]);
    return [[[element children] objectAtIndex:0] stringValue];

}
}

NSMutableDictionary* d = [NSMutableDictionary dictionary];
for(CXMLNode* child in [element children]) {
id v = [Soap deserialize:child];
if(v == nil) { v = [NSNull null]; }
[d setObject:v forKey:[child name]];

if( check != nil ) {             
NSInteger next = 1;             
key = [NSString stringWithFormat:@"%@%04d", [child name], next];
check = [d objectForKey:key]; 
while( check != nil ) {                 
    next++; 
    key = [NSString stringWithFormat:@"%@%04d", [child name], next]; 
    check = [d objectForKey:key]; 
} 
[d setObject:v forKey:key]; 
} else {
[d setObject:v forKey:[child name]];
}

阅读复杂的肥皂响应，使用Sudzc [iOS]拥有ID和IDREF节点
