thanks for your advice but now the message in the log window is:
*** -[NSCFArray objectAtIndex:]: index (1) beyond bounds (1)

Can you please suggest me something to fix it?


Bug-fixing tip number 1: Don't do that.

In particular: Stop trying to index past the end of the array.

Take a close look at your 'for' loop, and consider what happens if the array contains fewer than 7 items.

Then look at the basic documentation for NSArray and read about the - count method.
