Question

Rather than implementing a clunky, potentially bug-ridden custom table, I went with the much simpler rotate table option. The problem comes in when I decide that, rather than initializing rotated contents, I want to rotate the cell itself and cut down on the amount of code in complex cells.

The following lines are immediately after cell configuration.

This causes every cell to rotate 90° on load, regardless of orientation:

cell.transform =
      (CGAffineTransform)CGAffineTransformRotate(cell.transform, (M_PI / 2.0));

cellRotated = YES;

And this option only rotates the first cell once, but preserves the rotation:

if (!cellRotated) {
    cell.transform =
      (CGAffineTransform)CGAffineTransformRotate(cell.transform, (M_PI / 2.0));

    cellRotated = YES;
}

Can cell orientation be tracked with an existing function (or set thereof)?

I can’t find anything about this with Google. There are related questions, but mostly about tables and Portrait/Landscape UI orientations, so the counter-rotation implementation is quite a bit different.

EDIT

If I move cellRotated = YES to viewDidAppear: every cell except one gets rotated. (And then cell reuse makes it so that, in this case, every sixth cell is left alone.)
1-5 is good, 6 is bad, 7-11 is good, 12 is bad, etc (and then it changes in a perfectly logical but entirely unwanted pattern when I hit the end of the table)

Halfway there or a step back, I don’t know, but that’s what I have now.

Answer 1

If rotation is the only transform you do then why don’t you just do this,

cell.transform = CGAffineTransformMakeRotation(M_PI/2.0);

and then,

if ( !CGAffineTransformIsIdentity (cell.transform) ) {
    // Rotated.
}
