i used pull refresh: https://github.com/leah/PullToRefresh at my app,but when i pull height too big,it give me crash :NSArrayM objectAtIndex: index 5 beyond bounds for empty array,if my tableview cell only visit 4 cells,it give me :NSArrayM objectAtIndex: index 4 beyond bounds for empty array,if only 3 cells can visit it give me NSArrayM objectAtIndex: index 3 beyond bounds for empty array. at the same i used other pull refresh lib like:https://github.com/emreberge/EGOTableViewPullRefresh as so on,give me the same error.

Answer 1

Of course it is beyond bounds: your array is empty, you can not extract any object form it.

If the array has n objects, you can retrieve up to index n - 1. An empty array has 0 objects, so you can not even retrieve index 0.
