Checking if an object is empty
BOOL RSIsEmpty(id obj) {
return obj == nil || obj == [NSNull null] || ([obj respondsToSelector:@selector(length)] && [(NSData *)obj length] == 0) || ([obj respondsToSelector:@selector(count)] && [obj count] == 0);
}
BOOL RSStringIsEmpty(NSString *s) {
/*22 Feb. 2011: added NSNull check. JSON parser can put a null where we expect a string, and NSNull throws an exception when checking length. Since [NSNull null] is, arguably, emptiness, it makes sense to include it.*/
return s == nil || (id)s == (id)[NSNull null] || [s length] == 0;
