Flipped NSImage in the NSCell

Question

Why NSImage drawn flipped in the NSCell of NSTableView. And how proper fix that behavior. I returns image from the data source method:

- (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row {
return [NSImage imageNamed: @"test.png"];
}

As workaround I tried:

[NSImage setFlipped:NO];

All is ok but as documentation says that it deprecated method

osx 10.7-10.9

Answer 1

Here is some info I just came across.

Basically according to the link you have to:

1. Drag an image cell in the column you wish to show the image

2. Return an NSImageCell initialised with your image, like so:

    - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row { NSCell *imageCell = [[NSCell alloc] initImageCell:[NSImage imageNamed: @"test.png"]]; return imageCell; } 

Answer 2

I solved problem by replacing code of getting image from:

return [NSImage imageNamed: @"test.png"];

to:

NSData * imageData = [NSData dataWithContentsOfFile: [[NSBundle mainBundle] pathForImageResource: test.png]];
return [[NSImage alloc] initWithDataIgnoringOrientation:imageData];

I don't know reason of that behavior and documentation nothing says me. But I'll happy if you explain me.
