I have an iOS app that displays a CPTBarPlot. My plot bar responds to barTouchUpAtRecordIndex: by changing the background bar color but I also want to change the text label background and font color for that index. How can I change it?
The font color is part of the text style for the label. CPTTextLayer (the layer class used to display text in Core Plot) is a subclass of CPTBorderedLayer so it can have a border line and a fill behind the text. Set the padding to control how much of the fill is visible around the text.

Let's say I have a UIButton with a size of 120 wide by 30 high. I set an attributed title on it with centered text and I set a background color on the text of the attributed text for the .highlighted state.
When the user highlights the button, I want the background that shows around the title to have the same frame as the button.
I've tried positive and negative values for the button's titleEdgeInsets and contentEdgeInsets with no luck. Any suggestions here? Thanks
The easiest (meaning most controllable) way in my opinion is to use a button subclass and override titleRect. It's called when highlighted and when unhighlighted so you get a chance to change your answer depending on the state.
However, that won't change the size of the background color of attributed text, because it applies only to the text. You'd need to change the background color of the title label itself.
I have a UILabel that whose background I want to set to black with alpha component so that this label can have a transparent black background.
In the storyboard when I set the background to the colour I want with an alpha component even the text of the label that is in white colour becomes lighter with the alpha component.
To overcome this problem I embedded the label in a UIView and even then the same problem persists.
How can I overcome this problem. Any help will be appreciated.
You can Do only With label make IBObject an write following line.
label.backgroundColor = UIColor.black.withAlphaComponent(0.4)
Instead of changing the alpha value, change the opacity of the label background color in storyboard.
For better understanding, I have taken an imageView and placed a label at the bottom of imageView and changed the background color of the label and textColor to white. At this stage you can't see the image behind the label.
Now, go to attributes inspector and select the label background color. There you can see the opacity and change it's value. Here I have made it 50%, you can change it to whatever you want between 0 to 100 until you get your desired transparency.
create the UIview with black background color and add the UIlabel inside the view and set the alpha to 0.5 of view . finally you get the black transparent, for e.g
if you need the label text in bold change the view hierarchy
place the UILabel fist then add the UIView.
Place the UILabelabove the UIView, not inside it.
Assume that we are talking about v1 the view that contains your label , if v1 is over another view that has bright colors then when your v1's alpha get lower your label white text color will become harder to see , the text color has nothing to do with the background alpha component , so you need to reconsider using the white color or the alpha component background or the view that is behind v1 make it darker that's all we can say
I would like to set the colors for a textView to dark to avoid to stress the eyes when working on text.
If I set for example the field background to be black and the text to be white, the text color selection becomes a bit hard to see.
This is the code I'm using:
mainTextField.backgroundColor = UIColor.black
mainTextField.textColor = UIColor.white
Is there a way to have te selection of the text more visible?
I believe the text selection color is managed by the tintColor. You could set it to whatever you like by setting mainTextField.tintColor = UIColor.orange
UITextView text selection highlight color is determined by either the global or the view tint color.
You can set the color in Storyboard, by going to file inspector and setting the global tint color, or in attributes inspector of UITextView to apply it specifically for that view.
I also suggest that you set text color to Light Text Color.
So, I was trying to mimic a video that uses sketch to design a login screen I really like. I had a question about how I can make a text field in Xcode look like the one that is being designed in the video.
Here is the video link: https://www.youtube.com/watch?v=gA_hFHkhqFM&t=87s
Here is a picture of the text field I want to design:
Any help is appreciated!
This is how to do it in the storyboard
Find/Create a blurry image and set it as an image view's image. Fill the view with the image view and add constraints. Add a new text field on top of the image view. Set these things:
border style to none
Text color to white
Background color to a black color with an alpha value and tint color to white as well.
This can be set by using the RGB slider in the color picker. Use the slider at the very bottom to adjust the alpha:
The easiest way to do it is to add a UIView with a black background. Set its alpha to 0.7.
Then add a UITextField on top. Set its border style to none, then the background color to clear.
You're done!
I'm currently using a UITextView and setting its attributedText property, but I can't see a way to set the underline color different from the text color using my NSMutableAttributedString. Am I just missing something? Is this possible?
Do I need to look into CoreText? Is it possible there?
You can set two UITextViews with the same text and different colors on top of each other, with the textview underneath underlined.
