    <p>I have a JSON that looks like this here: </p> <pre><code> { "key1":[ { "desc":"key1decs.", "duration":50; },{ "desc":"", "duration":90; },{ "desc":"Kurz vor...", "duration":30; } ], "key2":[ { "desc":"key2decs.", "duration":50; },{ "desc":"blabla", "duration":90; } ] } </code></pre> <p>I am trying to do a mapping. But I'm stuck because of different unknown/arbitrary keys. I tried mapping without KVC, but it seems not to be working. Gives me error: Failed transformation of value at keyPath 'key1.desc'. No strategy for transforming from '__NSArrayI' to 'NSString'. and so on for every attribute. I saw on the web that mapping without KVC doesn't support arrays as inner structures. Plz, help. What is right approach here? </p> <p>EDIT: ENtity:</p> <pre><code>@interface Sendung : NSObject @property (nonatomic, strong) NSString *description; @property (nonatomic, strong) NSNumber *duration; @property (nonatomic, strong) NSNumber *sendungkey; @end; </code></pre> <p>Controller:</p> <pre><code> RKObjectMapping* mapping = [RKObjectMapping mappingForClass:[Sendung class]]; mapping.forceCollectionMapping = YES; [mapping mapKeyOfNestedDictionaryToAttribute:@"sendungkey"]; [mapping mapKeyPath:@"(sendungkey).desc" toAttribute:@"description"]; [mapping mapKeyPath:@"(sendungkey).duration" toAttribute:@"duration"]; [[RKObjectManager sharedManager].mappingProvider addObjectMapping:mapping ]; mapping = [[RKObjectManager sharedManager].mappingProvider objectMappingForClass:[Sendung class] ]; [[RKObjectManager sharedManager] loadObjectsAtResourcePath:url objectMapping:mapping delegate:self]; </code></pre> <p>This is what I get when NSlogin result: ( (null), (null), (null), (null), (null) )</p>

    1. COYes, because your key1's content is an array. Can you please post your entities as well as the mapping definition?

    2. COi edited the question. thank you! I tried to do it with NSDictionary, but since I don't know keys it makes me very confused (

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
