A stripped down version of your code works as expected here.
- (IBAction) test:(id) sender
{
//set coordinates to x,y -> 0,0 to start
float x = 0;
float y = 0;
while (YES) {
NSLog(@"x = %f, y = %f", x, y);
x = x+100;
//if coordinates are too wide, start new row - if x>300, reset x to 0 and add 100 to y
if(x > 300){
x = 0;
y = y+100;
}
}
}
I have in the past run into spooky code generation bugs.

I wonder if you've run into one too. Does it misbehave in both Debug and Release builds?
Also, are you sure x is getting past 300?

I can add a value to x and it draws the next image along, but I want to test the value of x and if it is out of bounds I want to reset it to zero and increase y, so I get a grid of images drawn.
