用的笨办法，写给自己看的
NSArray * array = [NSArray arrayWithObjects:@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9", nil];
NSInteger logIndex = 0;
NSMutableArray * tesarray;
NSMutableArray * finalArray = [[NSMutableArray alloc] init];
for (int i = 0; i < array.count; i++)
{
logIndex = logIndex + 1;
if (logIndex == 1)
{
tesarray = [[NSMutableArray alloc] init];
}
NSString * model = [array objectAtIndex:i];
[tesarray addObject:model];
if (i == array.count - 1)
{
if ((i+1)%2 != 0)
{
[finalArray addObject:tesarray];
}
}else
{
if (logIndex == 2)
{
logIndex = 0;
[finalArray addObject:tesarray];
}
}
}
NSLog(@"++++%@",finalArray);
