Modifying NSMutableDictionary from a single index format into nested (array within array)
- by Michael Robinson
I need to take the member ID off the top of this and create an array inside that contains the rest of the JSON return. Here is my JSON return.
[{"F_Name_VC":"Frank",
"L_Name_VC":"Johnson",
"userid":"18",
"age":"23",
},]
After it is json-deserialized it looks like this:
I need convert it to be transformed into this, with children sub-array:
Someone else posted a similar question but without the fact that it was coming from a JSON deserialization. There were two answers but no conclusion to the question.
(Answer 1):
NSDictionary *item1 = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@" member",[NSNumber numberWithInt:3],nil]
forKeys:[NSArray arrayWithObjects:@"Title",@"View",nil]];
Answer (2):
NSMutableArray *Rows = [NSMutableArray arrayWithCapacity: 1];
for (int i = 0; i < 4; ++i) {
NSMutableArray *theChildren = [NSMutableArray arrayWithCapacity: 1];
[theChildren addObject: [NSString stringWithFormat: @"tester %d", i]];
NSString *aTitle = [NSString stringWithFormat: @"Item %d", i];
NSDictionary *anItem = [NSDictionary dictionaryWithObjectsAndKeys: aTitle, @"Title", theChildren, @"Children"];
[Rows addObject: anItem];
}
NSDictionary *Root = [NSDictionary withObject: Rows andKey: @"Rows"];
Here is my JSON return and save code:
NSData *jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding];
NSError *error = nil;
NSDictionary * dict = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error];
if (dict)
{
rowsArray = [dict objectForKey:@"member"];
[rowsArray retain];
}
Thanks in advance. Every tutorial on JSON only shows a simple array being returned, never with children..It's driving me crazy trying to figure this out.
