Why doesen't the number 2 work in this for-loop?
- by Emil
Hello.
I have a function that runs trough each element in an array.
It's hard to explain, so I'll just paste in the code here:
NSLog(@"%@", arraySub);
for (NSString *string in arrayFav){
int favoriteLoop = [string intValue] + favCount;
NSLog(@"%d", favoriteLoop);
id arrayFavObject = [array objectAtIndex:favoriteLoop];
[arrayFavObject retain];
[array removeObjectAtIndex:favoriteLoop];
[array insertObject:arrayFavObject atIndex:0];
[arrayFavObject release];
id arraySubFavObject = [arraySub objectAtIndex:favoriteLoop];
[arraySubFavObject retain];
[arraySub removeObjectAtIndex:favoriteLoop];
[arraySub insertObject:arraySubFavObject atIndex:0];
[arraySubFavObject release];
id arrayLengthFavObject = [arrayLength objectAtIndex:favoriteLoop];
[arrayLengthFavObject retain];
[arrayLength removeObjectAtIndex:favoriteLoop];
[arrayLength insertObject:arrayLengthFavObject atIndex:0];
[arrayLengthFavObject release];
}
NSLog(@"%@", arraySub);
The array arrayFav contains these strings: "3", "8", "2", "10", "40".
Array array contains 92 strings with a name.
Array arraySub contains numbers 0 to 91, representing a filename with a title from the array array.
Array arrayLength contains 92 strings representing the size of each file from array arraySub.
Now, the first NSLog shows, as expected, the numbers 0 to 91.
The NSLog-s in the loop shows the numbers 3, 8, 2, 10, 40, also as expected.
But here's the odd part: the last NSLog shows these numbers:
40, 10, 0, 8, 3, 1, 2, 4, 5, 6, 7, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91
that is 40, 10, 0, 8, 3, and so on.
It was not supposed to be a zero in there, it was supposed to be a 2..
Do you have any idea at why this is happening or a way to fix it? Thank you.
