RestKit ios嵌套同一類型的對象

Question

如何映射同一類型的嵌套對象？ 我有一個XML與可以包含相同類型的多個對象的對象：

<entry location="l1"> 
    <entry location="l1.1"> 
     <entry location="l1.1.1"> 
     </entry> 
     <entry location="l1.1.2"> 
     </entry> 
    </entry> 
</entry> 

我得到一個無限遞歸如果我添加propertymapping用相同的映射：

+ (RKObjectMapping *)objectMapping { 
    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Entry class]]; 
    [mapping addAttributeMappingsFromDictionary:@{@"location": @"location"}]; 
    [mapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"nextEntries" 
                      toKeyPath:@"entries" 
                      withMapping:[Entry objectMapping]]]; 

    return mapping; 
} 

是有可能將子對象添加到每個父對象的數組中？

歡呼

//編輯：下面的代碼工作對我來說：

+ (RKObjectMapping *)objectMapping 
{ 
    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Entry class]]; 
    [mapping addAttributeMappingsFromDictionary:@{@"location": @"location"}]; 

    RKObjectMapping *innerMapping = [RKObjectMapping mappingForClass:[Entry class]]; 
    [innerMapping addAttributeMappingsFromDictionary:@{@"location": @"location"}]; 

    [mapping addPropertyMapping:[RKRelationshipMapping 
     relationshipMappingFromKeyPath:@"entry" 
     toKeyPath:@"entries" 
     withMapping:innerMapping]]; 

    return mapping; 
}

我還沒有嘗試過，所以我不知道這是否會工作，但試試這個：

+ (RKObjectMapping *)objectMapping 
{ 
    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Entry class]]; 
    [mapping addAttributeMappingsFromDictionary:@{@"location": @"location"}]; 

    RKObjectMapping *innerMapping = [RKObjectMapping mappingForClass:[Entry class]]; 
    [innerMapping addAttributeMappingsFromDictionary:@{@"location": @"location"}]; 

    [mapping addPropertyMapping:[RKRelationshipMapping 
     relationshipMappingFromKeyPath:@"nextEntries" 
     toKeyPath:@"entries" 
     withMapping:innerMapping]]; 

    return mapping; 
} 

不確定toKeyPath:@"entries"是否正確，它可能需要基於您的XML爲toKeyPath:@"entry"。

無限遞歸是因爲你調用自己的方法（[Entry objectMapping]），它與映射無關。
