My app when I run it on my phone I get this error:
I just tried to parse a json and trying to use images in two column of custom cell, but my images on scroll are mis-placed.
int index=indexPath.row*2;
int newindex=index+1;
NSDictionary *u = [[results objectAtIndex:index]mutableCopy ];
NSLog(@"NSDictionary *u = [results objectAtIndex:index] %@",u);
NSDictionary *u1 = [[results objectAtIndex:newindex]mutableCopy];
NSLog(@"NSDictionary *u1 = [results objectAtIndex:newindex] %@",u1);
But if i use both index and newindex same value it works.

Educated guess:
This line causes your problem:
There are 4 different possibilities how the first if will come out:
First case is no problem at all. Last case neither. In case 2 and 3 allKeys will be called on a object that is not a NSDictionary.
You should probably replace it with an “if” that needs both tests to be true.
Another option would be to check individually.
