First of all, sorry for the title and asking this incredibly question but I simply couldn't figure it out. Also, since it is not related to code, I don't have code to show
I am working on an app and using iOS7 and I created a button from IB, set its background image to an image I designed. Connected it with header and set its touch up inside action as an IBAction
Yet, here is my problem. Whenever I click on the button, as an effect the image fades half transparent. I do not want this default attribute. I checked all the states on IB (highlighted, disabled, selected) and couldn't figure it out.
If I create the same button programmatically, only the text color changes, however when I set the background image, image fades (perhaps to indicate the button being pressed). How can I remove this effect?
A bit late but I believe this would solve the problem
in the xib file, set the button's type to Custom.
My button was set to system and when pressed on, it shows transparency and has a little fade in effect. Once I changed it to custom this effect is gone.
This cannot be changed once button is created. only in xib or when the button is first created.
have you tried this one yourButton.adjustsImageWhenHighlighted = NO?
If you set same background-image/background-color for every buttons states in IB (highlight, disable, selected) you will not get any fading in UIBUtton when you press it. You can set text color for every states also. If needed you can set different colors for every state and check the press action.
Hope the answered you expect. Thanks
Storyboard Solution
1:set button type to custom
2:uncheck "Highlighted adjusts Image"
If you want fading in & out effect your UIButton Type Should be a system, not custom.

I have problem when in iOS settings is enabled this setting "Button Shapes"
It causing this underline in application (first picture with enabled setting, second without)
Any idea how to programatically or in storyboard disable it?
I tried attributed text but I get same result :(
I'm newbie in Swift.
Thanks for help!
It's not a problem. You should not make any attempt to counter any accessibility changes set by the user. They are there for a reason.
This is an answer by user4291543 from this question Remove underline on UIButton in iOS 7
[yourBtnHere setBackgroundImage:[[UIImage alloc] init] forState:UIControlStateNormal];
I found this answer works with SWFrameButton
And for all the others saying "Don't Do This", SWFrameButton is a very good example of when you would want to do this. I also think the OP's situation is a perfectly valid scenario as well...
I totally agree with #maddy's comment:
It's not a problem. You should not make any attempt to counter any accessibility changes set by the user. They are there for a reason.
But I did stumble on a way to accomplish the task at hand...
In addition to a UIButton, you'll also need to make a .png file that contains nothing (meaning the entire contents have an opacity of 0%). Go ahead and load that into your xcode project's assets.
Now go ahead and set the Button's Background to that image you just provided. (In my case, I called it clear) This will remove the underline from the button's text. However, now you can't see the boundaries of the button. This can be solved by changing the Background of the button's View. Go ahead and select any color for the View's Background property and now the background of the View visibly defines the button's boundaries. You're able to see this because your clear.png has an opacity of 0%.
see the Attributes inspector for UIButton here.
Rather than trying to defeat the underline by going to make a label perform some action via UITapGestureRecognizer, this allows you to still use a UIButton. Keeping inline with accessibility features to mark buttons for people that want to do that.
You could create a custom button class with a label (with clear color). If you set the text of this label instead it shouldn`t get an underline.
Are you sure you want to do that?
Apple added an accessibility feature to mark buttons for people that want to do that. Apple will probably reject your app because it defeats a system function meant to help the disabled.
I found the solution. All you have to do is set a picture as the background of the button. just pick a picture with the same color as the button you created.
When I tap or hold down on any of my UIButtons, their alpha seems to fade to about 0.1. I never added this functionality in, so I'm assuming it's automatic.
How do I disable this so that my button doesn't fade when tapped or held down? I want my button to remain at alpha 1 all the time.
I've tried button.adjustsImageWhenHighlighted = NO; to no avail, as well as a few other suggestions on here.
Did you try using the same image for both the "normal" and "highlighted" states?
Maybe showsTouchWhenHighlighted also affects the situation.
Are you using background images for your buttons too?
Are you disabling the button upon tapping? Disabling also affects appearance (unlike userInteractionEnabled).
Are you using IB/Storyboards?
As you can see, there is a number of factors that can play a role into what's happening.
Any code you can show with specifics of your situation?
Edit: If you are not using an image (you mentioned adjustsImageWhenHighlighted), then just set the button type to "custom" in IB. You won't get the system provided "default" behavior.
just uptick the Disabled Adjusts Image in your MainStory Board in your buttons configuration next to the Drawing section
I'm using Xcode 5.1.1. I recently added a background image to my application but the buttons on the view controller aren't visible. When I remove the background image, the buttons become visible again. How to handle this?
If you are not checking the view hierarchy, then do one thing create outlet of you button and then write following code in viewDidLoad.
[self.view bringSubviewToFront:yourButton];
I don't know if you were used xib...
If you are using xib in your project, giving a background image for your button will more easy.
Place a button anywhere you want. Then go to attributes inspector on the right hand side. There you can find a field for changing your background image. Just give the name of your image.
Hope it will helpful for you
Is this possible? It seems shoddy for it not to be.
I'm trying to create a toggle button (not a UISwitch) in IB. For example a mute button, when muted would have some indication that sound is disabled, when you hit it, that indicator disappears (but still the same underlying graphic), and toggles between these states each time it is pressed.
This functionality can be achieved using the selected property, however you can't change the Selected AND Highlighted property in IB like you can in code, so whenever the button is pressed, no matter the state, the highlighted image is the same, which looks terrible and glitchy.
Is there a way to fix this with just IB, or do I have to make a custom class to avoid manually loading in all these buttons?
Have you thought about subclassing UIButton to add in the things you need?
I'm doing a custom nav in ios for the first time. I have six buttons laid out in a row. When I tap the button, I want the image to change. However, the button is not togglable. The only way a button can be unselected is if another button is touched. Only one button can be active at any given time.
My idea:
use UIButtons
change UIButton image on touch
keep track of the active button inside the navigation class
when an inactive button is touched, make the currently active button inactive and turn the touched button to active
I want the end product to work like a custom TabBarController, but without switching layouts. I just want to edit the content in the current ViewController.
Is there a better way to do this?
You could just use the UISegmentedControl, which has that functionality already. If you need to significantly customise the look and feel though, your UIButton solution sounds fine.
I setup the UIButtons in the Interface Builder like so:
Default with unselected background image
Disabled with selected background image
On touch, a button is self.enabled = NO which makes the UIButtons look change. However, the button goes dim, so I also implemented self. adjustsImageWhenDisabled = NO.
This way a button can't be re-selected once it's "active".
