Question

I am having problem with using subArrayWithRange.

Basically, what I want to do is make subarray of 50 elements or less from mainArray
for example if mainArray has 70 elements I want a sortedArray to have an array of first 50 elements in first index and another array of 20 elements in the last index of sortedArray

Hope I am clear what I want to do get.

anyway, my code is

for (int i=0; i<=ceilLoopCount; i++) {
    [sortedArray insertObject:[testArray subarrayWithRange:NSMakeRange(0,50)] atIndex:i]; 
} 

and the problem I am having is I only get the same 50 elements in all the array

Please help,
Pondd

NSUInteger size = 50;

for (NSUInteger i = 0; i * size < [testArray count]; i++) {
  NSUInteger start = i * size;
  NSRange range = NSMakeRange(start, MIN([testArray count] - start, size));
  [sortedArray addObject:[testArray subarrayWithRange:range]];
}
