For anybody who has the same problem, here's how I solved it: 1. Download JSON file to local storage using AFHTTPRequestOperation's output stream. 2. Parse little chunks of NSData using YAJLParser. Result: I was testing it on 50mb json on iPad (1), without any memory warnings (memory around 10mb). Example: <pre><code> NSError *error = nil; NSData *data = [NSData dataWithContentsOfFile:path options:NSDataReadingMappedAlways | NSDataReadingUncached error:&error]; YAJLParser *parser = [[YAJLParser alloc] initWithParserOptions:YAJLParserOptionsAllowComments]; parser.delegate = self; [parser parse:data]; parser.delegate = nil; parser = nil; </code></pre> YAJLParser delegate: <pre><code>// first declare in header file NSMutableArray *stack and NSString *mapKey - (void)parserDidStartDictionary:(YAJLParser *)parser { NSString *dictName = mapKey; if (mapKey == nil) { dictName = (stack.count == 0) ? @"" : [stack lastObject]; } [stack addObject:(dictName)]; } - (void)parserDidEndDictionary:(YAJLParser *)parser { mapKey = nil; [stack removeLastObject]; } - (void)parserDidStartArray:(YAJLParser *)parser { NSString *arrayName = mapKey; if (mapKey == nil) { arrayName = stack.count == 0 ? @"" : [stack lastObject]; } [stack addObject:(arrayName)]; if([mapKey isEqualToString:@"something"]) { // do something } } - (void)parserDidEndArray:(YAJLParser *)parser { if([mapKey isEqualToString:@"some1"]) { // do something } mapKey = nil; [stack removeLastObject]; } - (void)parser:(YAJLParser *)parser didMapKey:(NSString *)key { mapKey = key; } - (void)parser:(YAJLParser *)parser didAdd:(id)value { if([mapKey isEqualToString:@"id"]) { // do something } } </code></pre>

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.
