I have an NSTextField. I want it to draw text and have a background color. But when I set drawsBackground to YES, the text seems to draw partially transparently. For example, if I set the text color to white and background to black, the text comes out gray. Why is this?
Make sure isEnabled set to true.
I was seeing this as well and changing this fixed it for me.

I tried my hands on changing the color of NSPopover, I am able to change to it all desired color except transparent.
As, it is known that NSPopover is by default semi transparent. I tried changing the NSWindow color directly, by Layer as well, I also tried setting the NSView's color to transparent i.e. NSColor.Clear but no luck.
So the question is - Is this possible to change the background color of NSPopover to transparent?
No this is (sadly) not possible.
I realized that suddenly (without me touching the corresponding code) my NSBox has a double visualization. It is as if the Box has a background color and draws its normal rounded frame inside. I added a small screenshot. The parent control is white, the NSBox is gray with the title "Inputs" (unchanged titlePosition). Under the title is the normal box, adding a 2nd shade of gray.
I did not change any of the usual suspects, especially not boxType which is still set to .primary.
I did work on the Dark Mode (Dark Aqua) but cannot see any change that would cause this behaviour. effectiveAppearance is still Aqua.
A NSBox with a boxType of .primary always draws a background. That is intended behaviour. Only if the view behind NSBox is white you may not see it. If you want a NSBox without background you must make it boxType .custom and set the background color as required.
I have an SKView with a picture of a keyboard in a window as shown below. I would like the background color of the SKScene it's presenting to be the same color as the window behind it, so that it would appear as if the keyboard was just in the window, and not in something else that was in the window. After consulting the NSColor documentation, I tried setting the background color of the SKScene as NSColor.windowBackgroundColor(). The color below is what I got. I'm assuming there was some kind of error and so it defaulted to black. That being said, how do I access the default color of a window?
Set the SKView's allowsTransparency to true and then set the SKScene's backgroundColor to NSColor.clearColor().
I think that using windowBackgroundColor() gives black if the view doesn't allow transparency and works if it does because it's effectively being translated to clearColor() by "accident". windowBackgroundColor() is a bit strange. It's not in either an RGB nor a gray-scale color space and it can't be converted to either of those. I'm guessing that SKScene tries to convert the background color to the RGB color space and, when that fails, it uses clearColor() as a fallback.
Have any one else noticed in iOS7, the translucent navigation bar only shows color underneath if barTintColor is set to default?
I tried setting barTintColor to various different colors, but anything that is below the navigation bar is displayed a a black blur. Whereas if the barTintColor is set to default, all the elements display correctly underneath.
Is there a way to force it to show the correct colors?
You have to use background color instead of tint color.
self.navigationController.navigationBar.backgroundColor = [UIColor yellowColor];
If you are using tint color it changes only barbutton background color change.
In MyTabBarController in the storyboard select the color tint. You will change the button active color background. No idea for the inactive one.
When I use
[myNSTextField setStringValue:#"AAA"];
to set the text of a NSTextField
the texts always have black background and look likes they have been selected.
Is it possible to display the text with black text color and white background color?
Welcome any comment
Ask the text field to resignFirstResponder. That will deselect the view.
