Question

i am newBie in iOS Development. i want to add my JSON Parsing Data Dictionary Array Key Value in to another array But it only Add My Last Array index in to New Array.
My Code like as

{
if (responsedata.length > 0)
{
NSError* error;
self.json = [NSJSONSerialization JSONObjectWithData:responsedata options:kNilOptions error:&error];
if ([[_json objectForKey:#"data"] isKindOfClass:[NSArray class]])
{
NSArray *arr = (NSArray *)[_json objectForKey:#"data"];
[self.imageArray addObjectsFromArray:arr];
[self.storeViewTable reloadData];
}
self.storeViewTable.hidden=FALSE;
}
NSMutableArray *imagearray=[[NSMutableArray alloc]init];
for (index=0; index <[self.imageArray count]; index ++)
{
for(NSDictionary *dict in self.imageArray )
{
imagearray = [dict valueForKey:#"demopage"];
self.imagesa = imagearray;
}
}
NSLog(#"Array Count %d",[self.imagesa count]);
NSLog(#"Another array Count %d",[self.imageArray count]);
}

Answer 1

your code should look like below.
id json = [NSJSONSerialization JSONObjectWithData:responsedata options:kNilOptions error:&error];
if ([[json objectForKey:#"data"] isKindOfClass:[NSArray class]])
{
NSArray *arr = (NSArray *)[json objectForKey:#"data"];
[imageArray addObjectsFromArray:arr];
}
//do not alloc init if you have already alloc init array.
NSMutableArray *imagesa=[[NSMutableArray alloc]init];
for(NSDictionary *dict in imageArray )
{
[imagesa addObject:#{#"demopage":[dict valueForKey:#"demopage"]}];
}
NSLog(#"Array Count %lu",(unsigned long)[imagesa count]);
NSLog(#"Another array Count %lu",(unsigned long)[imageArray count]);
and i got below output
Array Count 3
Another array Count 3
NOTE
and if you want to add all demopage dictionary to imagesa array then replace your for loop
for(NSDictionary *dict in imageArray )
{
NSArray *arr = (NSArray *)[dict valueForKey:#"demopage"];
[imagesa addObjectsFromArray:arr];
}
and output is
Array Count 69
Another array Count 3
