key in one array and the value in the another array and the value array is in object format.
I need to store the multi object for the single key. The attributeArray
has the key value and the elementsArray
has the object. For example the attributeArray might have the values
" English, French, German..."
and the elementsArray might have the object value
"<Row: 0x4b29d40>, <Row: 0x4b497a0>, <Row: 0x4e38940>, <Row: 0x4b2a070>, <Row: 0x4b29ab0>, <Row: 0x4b178a0> "
In the first value I need to store the two object and for second key I need to store 3 objects and for the third key in need to store last two objects in the dictionary.
For super-simplification you can use the following code:
NSArray *keys = ...;
NSArray *values = ...;
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithObjects: values forKeys: keys];
Hope, this helps.
UPDATE:
to store multiple values for single key in the dictionary, just use NSArray
/ NSMutableArray
as your object:
NSArray *keys = ...;
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
for( id theKey in keys)
{
NSMutableArray *item = [NSMutableArray array];
[item addObject: ...];
[item addObject: ...];
...
[dict setObject: item forKey: theKey];
}
If you don't know all the values for the key from the beginning and need to add them one by one, you can use the following approach:
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
for( /*some cycling condition here */)
{
id keyToUse = ...;
id valueToAdd = ...;
id foundArray = [dict objectForKey: keyToUse];
if ( nil == foundArray )
{
foundArray = [NSMutableArray array];
[dict setObject: foundArray forKey: keyToUse];
}
[foundArray addObject: valueToAdd];
}
