Objective C loop logic
- by Graham
Hi guys,
I'm really new to programming in Obj-C, my background is in labview which is a graphical programming language, I've worked with Visual Basic some and HTML/CSS a fair amount as well. I'm trying to figure out the logic to create an array of data for the pattern below. I need the pattern later to extract data from another 2 arrays in a specific order.
I can do it by referencing a = 1, b = 2, c = 3 etc and then creating the array with a, b, c but I want to use a loop so that I don't have 8 references above the array. These references will be used to generate another generation of data so unless I can get help figuring out the logic I'll actually end up with 72 references above the array.
// This is the first one which gives the pattern
0 0 0 0 (etc) // 1 1 1 1 // 2 2 2 2
NSMutableArray * expSecondRef_one = [NSMutableArray array];
int a1 = 0;
while (a1 < 9) {
int a2 = 0;
while (a2 < 8) {
NSNumber * a3 = [NSNumber numberWithInt:a1];
[expSecondRef_one addObject:a3];
a2++;
}
a1++;
}
// This is the second one which I'm stumbling over, I am looking for the pattern
1 2 3 4 5 6 7 8 //
0 2 3 4 5 6 7 8 //
0 1 3 4 5 6 7 8 //
0 1 2 4 5 6 7 8 // etc to -> // 0 1 2 3 4 5 6 7
If you run it in a line every 9th number is -1 but I don't know how to do that over a pattern of 8.
Thanks in advance!
Graham
