Answer 1

change this
self.values=[_serviceResponse objectForKey:#"SESSIONCOUNT"];
NSLog(#"got response==%#", self.values);
int i;
for (i=0; i<[self.values count]; i++) {
NSDictionary *exp=[self.values objectAtIndex:i];
_item=[exp objectForKey:#"COUNTVALUE"];
//[self.testARYY addObject:item];
}
[self.values addObject:_item];
into and try
NSArray *temp = [_serviceResponse objectForKey:#"SESSIONCOUNT"];
if (temp.count>0)
{
[self.values removeAllObjects];
self.values = [NSMutableArray new];
for (i=0; i<[temp count]; i++) {
[self.values addObject:[NSString Stringwithformat:#"%#",[[temp objectAtIndex:i] objectForKey:#"COUNTVALUE"]]];
}
}
or use like
Choice-2
NSArray *temp = [_serviceResponse objectForKey:#"SESSIONCOUNT"];
if ([temp isKindOfClass:[NSArray class]] && temp.count !=0)
{
// value is available
[self.values removeAllObjects];
self.values = [NSMutableArray new];
for (i=0; i<[temp count]; i++) {
[self.values addObject:[NSString Stringwithformat:#"%#",[[temp objectAtIndex:i] objectForKey:#"COUNTVALUE"]]];
}
}
Update-2
if( [_serviceResponse objectForKey:#"SESSIONCOUNT"] == nil ||
[[_serviceResponse objectForKey:#"SESSIONCOUNT"] isEqual:[NSNull null]] ){
// do nothing
}else
{
NSArray *temp = [_serviceResponse objectForKey:#"SESSIONCOUNT"];
if ([temp isKindOfClass:[NSArray class]] && temp.count !=0)
{
// value is available
[self.values removeAllObjects];
self.values = [NSMutableArray new];
for (i=0; i<[temp count]; i++) {
[self.values addObject:[NSString Stringwithformat:#"%#",[[temp objectAtIndex:i] objectForKey:#"COUNTVALUE"]]];
}
}
}

Answer 2

You should try to change this line:
return [[self.values objectAtIndex:index] floatValue];
to this
return [[self.values objectAtIndex:index][#"COUNTVALUE"] floatValue];
The error says that you are trying to call the floatValue function on a NSMutableDictionary, from my understanding you should call it on the value stored under the "COUNTVALUE" key of the dictionary.
