Question

Sudzc生成的代码正在为反序列化节点编写字典。如果我使用NSLog（@“子节点：％@”，[[[element children] objectAtIndex：0] stringValue]）;它会在每次通过时写出正确的项目。当我尝试在代码中检索结果时，只有最后一个可用（杰克逊3）。我究竟做错了什么？

// 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;
}

的NSLog：

解决了（改变了soap.m）：

[d setObject:v forKey:[child name]]; 
NSString* key = [child name]; 
id check = [d objectForKey:key]; 
if( check != nil ) { 

    NSInteger next = 1; 
    key = [NSString stringWithFormat:@"%@%d", [child name], next]; 
    check = [d objectForKey:key]; 
    while( check != nil ) { 

        next++; 
        key = [NSString stringWithFormat:@"%@%d", [child name], next]; 
        check = [d objectForKey:key]; 
    } 
    [d setObject:v forKey:key]; 
} 
[d setObject:v forKey:[child name]];

Answer 2

一旦我得到足够的重复点，我会，但我注意到代码以

开头和结尾

  [d setObject:v forKey:[child name]];

对我来说，我必须删除初始行，并为我修复它，所以代码看起来像这样：

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

if([element childCount] == 1) {
    CXMLNode* child = [[element children] objectAtIndex:0];
    if([child kind] == CXMLTextKind) {            
    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]]; //seems to be duped (maybe my bad)

    //http://stackoverflow.com/questions/10235496/sudzc-deserializeasdictionary-over-written-dictionary/10358458#10358458
    NSString* key = [child name]; 
    id check = [d objectForKey:key]; 
    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]; 
    } 
    [d setObject:v forKey:[child name]]; 
    //End Extension
}
return d;

}

我发现你还必须放入一个其他块：

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]];
}
//End Extension

否则'd'中的元素将被覆盖，因为setObject被调用两次。

我不确定你是如何应用你的修补程序的，你是在替换 deserializeAsDictionary 中的整个代码还是追加到代码的末尾？

看到代码行有一个for循环

  [d setObject:v forKey:[child name]];

找到了

，所以我猜你只是扩展了它，这样你就可以在这里扩展它而不是关闭for循环，这是对的吗？

Answer 5

我遇到上述代码的问题 - 它每次都覆盖了第一个条目 - 即我会得到一个包含4个项目的列表，第一个和第四个将被复制。

在通过代码（爱的递归代码）之后经过了大量的精力充沛，我找到了我认为的问题;

我的代码如下：

    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]];
    }
