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?

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 want to change an UIToolBar at runtime. In it's initial state, is has only one button, when that button is pressed i want it to change it's appearance to show 4 buttons. One of these buttons should cause the first UIToolBar to reappear.
Im seeing two approaches:
1) Have two UIToolBar nibs, and load them as needed.
2) Having all buttons on the first UIToolbar, and hide/show them as needed.
What would be the correct approach?
Personally, I would want to see all 4 button at initial launch with only relevant button in enabled state and rest in disabled state. Once I tap on the already enabled button I should see other buttons getting enabled. This is less surprising UI for end user. However, you can also go with #2 mentioned above in which case you might want to add some animation effect for better user experience.
The second approach would be better, because if you want to add more buttons tomorrow, you need to maintain 2 nib files instead of one.
But, think again is creating toolbar in xib file good solution?
I would create custom toolbar extending UIToolbar class and make 2 methods in it:
-(NSArray*) toolbarButtonsInitial;
-(NSArray*) toolbarButtonsExtended;
-toolbarButtonsInitial method returns UIBarButtonItems for initial state
-toolbarButtonsExtended method returns UIBarButtonItems for second state.
IMHO, this way has several advantages:
Your xib file doesn't have hidden buttons, or some button above other
one
If you need to add or remove some buttons you can do that easily for
each state
You can easily reuse this toolbar on other screens and create new
states if necessary
I used this question:
How to create a UIButton with a black gradient for iPhone?
... to set up a color gradient as the background of my button and it looks great, but when I tap the button it doesn't visibly change and give the user any feedback that they successfully tapped the button.
How can I set up a second gradient for the highlighted state or something like that?
Well, you are setting a sublayer and not providing any content to the button's views. The sublayers are drawn directly, so the UIButton doesn't think it has any content to "highlight". If you want a different effect on your button when you select it, there are three simple approaches.
One is to make two images with gradients. A pressed and normal state. This is much simpler as you can design them as you want and its a simple one line, one time implementation.
The other option is adding selectors that get called when your button gets UIControlEventTouchDown and whichever other Control Event(s) you want to have it switch back under.
The last simple option is to subclass UIButton and use the UIResponder touch methods to determine when to manually switch between the different background types.
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".
My application has a few portions that have really big buttons (640x130, 230x150, etc.) What I need is to have a way to update different portions of the button, with different text. Initially, I assumed that in my code I could create various UILabels and then add them as subviews to my button. However, as soon as I try to add a UILabel to the button as a sub-view, my app crashes.
What is the easiest way to create an overlay for a button, that I can completely layout myself, without preventing button taps from being interested using overlay controls?
I imagine there are multiple ways to solve this problem. However, the best solution for my case should use the fewest lines of code (I have quite a few of these types of buttons) and I'd like to be able to continue using some form of configurable button within IB.
I'm not opposed to subclassing UIButton but, if I do, I would like to be able to use it in IB. I've never created a custom UIView for such a circumstance, so I'd need help defining that type of subclass so that it will work correctly in IB.
You need to add the subview to the containing view - not the button. To ensure that is doesn't interfere with button presses, be sure to set it to:
[myCustomTextOverlay setUserInteractionEnabled:NO];
