Answer 1

Your question is not clear. Possibly you need to get all keys in your dictionary and separating each item with specific word in it(checka/checkb/checkc).
If that is the case then,
You will get all the keys using:
NSArray *dictKeys = [yourDictionary allKeys];
You can implement this in multiple ways, one of them:
For storing it in same array:
for (NSString *key in [yourDictionary allKeys])
{
[yourArray addObject:[yourDictionary objectForKey:key]];
}
For storing it in seperate arrays:
for (NSString *key in [yourDictionary allKeys])
{
if([key rangeOfString:#"checka"].location != NSNotFound)
{
//add checka to first array
[yourFirstArray addObject:[yourDictionary objectForKey:key]];
}
else if([key rangeOfString:#"checkb"].location != NSNotFound)
{
//add checkb to second array
[yourSecondArray addObject:[yourDictionary objectForKey:key]];
}
...
}

Answer 2

if contryArray is your dictionary then access it as follow
[contryArray valueForKey:#"checka0"];
and go on adding this values to another array

Answer 3

You can use the following code:
- (void)filterDictionary:(NSDictionary *)dict
{
NSArray *allKeys = [dict allKeys];
NSMutableArray *allValues = [[NSMutableArray alloc]init];
for(id key in allKeys)
{
id value = [dict valueForKey:key];
[allValues addObject:[value stringValue]];
}
}
