Question

I have an application which is having a dictionary returned from a webservice.and i am passing that dictionary to another view controller.

and in this

NSDictionary *rewards=[rewardsdictionary objectForKey:@"rewards"];
NSLog(@"%@",rewards);

NSMutableArray *dataArray=[[NSMutableArray alloc] init];
for(NSString *key in [rewards allKeys])
{
    NSDictionary *dict1=[rewards objectForKey:key];
    [dataArray addObject:dict1];
}
self.rewardsarray=[[NSMutableArray alloc] init];
self.rewardsarray=dataArray;

But in this line for(NSString *key in [rewards allKeys]) the application is crashing.but when i am printing rewards or rewards dictionary the values are there.

-[__NSArrayM allKeys]: unrecognized selector sent to instance 0x76636b0

can anybody help me to get out of this?

Answer 1

Obviously, rewards is not a NSDictionary. It’s an NSArray.
