The important line is :

It means you are calling count on a string. The object you think is an array is actually a string.
From looking at your code, tempArr could be either an array or a string. Try this:
if ([tempArr isKindOfClass:[NSArray class]])
{
// Handle array case
}
else if ([tempArr isKindOfClass:[NSString class]])
{
// Handle string case
}
It's probably a good idea to change the name of tempArr to something else, like tempResponse or similar.
