Objective-C: Loop through NSDictionary to create seperate NSArray's
- by Nic Hubbard
I have a large NSDictionary structure that I need to loop through and create seperate NSArray's. Here is the structure:
(
{
id = {
text = "";
};
sub = {
text = " , ";
};
text = "";
"thumb_url" = {
text = "";
};
title = {
text = "2010-2011";
};
type = {
text = "title";
};
},
{
id = {
text = "76773";
};
sub = {
text = "December 13, 2010";
};
text = "";
"thumb_url" = {
text = "http://www.puc.edu/__data/assets/image/0004/76774/varieties/thumb.jpg";
};
title = {
text = "College Days - Fall 2010";
};
type = {
text = "gallery";
};
},
{
id = {
text = "";
};
sub = {
text = "";
};
text = "";
"thumb_url" = {
text = "";
};
title = {
text = "2009-2010";
};
type = {
text = "title";
};
},
{
id = {
text = "76302";
};
sub = {
text = "December 3, 2010";
};
text = "";
"thumb_url" = {
text = "http://www.puc.edu/__data/assets/image/0019/76303/varieties/thumb.jpg";
};
title = {
text = "Christmas Colloquy";
};
type = {
text = "gallery";
};
}
)
Each section has a type key, which I need to check. When it finds the "title" key, I need to add those to an array. Then the next sections that would use the "gallery" key needs to be in its own array until it finds another "title" key. Then the "gallery" keys after that into their own array.
I am using this a UITableView section titles and content. So, the NSDictionary above should have one NSArray *titles; array, and two other arrays each containing the galleries that came after the title.
I have tried using a for loop but I just can't seem to get it right. And ideas would be appreciated.
