wish helps you If [See valueForKey:@"class_name"] contains array then that is your error cause:
code :
[See valueForKey:@"class_name"];
className = [[NSMutableArray alloc]init];
className= [See valueForKey:@"class_name"];
className= [NSMutableArray arrayWithArray:[See valueForKey:@"class_name"]];

should help you out Developing ios app. I have an object class Product.h and .m respectively along with my picker class which implements my vehicle selection to match products to vehicle. The files , Your problem is this:
code :
self.dataArray = [[NSArray alloc] initWithObjects:nil];
self.dataArray = [NSMutableArray array];
self.propertyName = [dic objectForKey:@"dictionary key"];
[self.dataArray release];
self.dataArray = nil;
NSString *thisString = [[NSString alloc] initWithString:@""];
thisString = [NSString stringWithFormat:@"http://api.curthitch.biz/AJAX_CURT.aspx?action=GetHitch&dataType=json&year=%@&make=%@&model=%@&style=%@",year,make,model,style];
NSString *thisString = [NSString stringWithFormat:@"http://api.curthitch.biz/AJAX_CURT.aspx?action=GetHitch&dataType=json&year=%@&make=%@&model=%@&style=%@",year,make,model,style];

will be helpful for those in need Your request may be synchronous, but you dispatch them from the blocks that are scheduled for concurrent execution. This means that the NSLog statement can be reached before any of you requests are dispatched. You have two options to fix your problem:
Don't use dispatch_async and blocks, just simply send the requests inline. I wouldn't recommend this if the code that you showed runs on main thread. Register for completion callbacks and check your array of objects then. You can see how this can be done here in the completion callbacks section

I hope this helps . The array is immutable (NSArray), not mutable (NSMutableArray). You can create a mutable array from an immutable array using mutableCopy:
code :
NSMutableArray *replies = [[self.messageDictionary objectForKey:message] mutableCopy];
-[__NSArrayI addObject:]: unrecognized selector sent to instance ...

Does that help The essence of it is that you wrap your C struct in an Obj-C class. The Obj-C class to use is NSValue.
