I am making multiple custom buttons that look much like this:
It is a simple button with either the green or gray in the "indicator view". What I need some explanation for is: In interfacebuilder there are four states a button can have; Normal, Highlighted, Selected and Disabled. When I provide images for everything except disabled I thought that normal would be when no touches were made on the button, highlighted is while you hold your finger on it and selected would be when after you release finger.
However I do not think thats right now. I use the touch-up-inside event. Is it correct that I need to set the selected/highlighted etc property on the button?
Thank you for your time.
You might want to set to selected and not highlighted.
Highlight is darkening the button for a fraction when touching the UIButton. UIButton can modify your image automaticaly so usually you don't need to provide a highlight image.
Disabled is when it is disabled.
Selected is when it is selected. You can invert the select flag on touch up inside event to make a state button.
[button setSelected:![button isSelected]];
Yes, you need to respond to the touch up inside by setting the button to highlighted.
Btw, it's "disabled" not deselected, but it doesn't sound like you need that state.

I am trying to set a state for UIButton.
But i don't know the difference between the UIControlStateHighlighted and UIControlStateSelected.
Could anyone help me out?
Thanks and best regards.
They can mean whatever you want them to, but in general they mean the following:
Highlighted = The user is currently interacting with something that will change once they stop interacting (e.g. holding down a button)
Selected = The item is current the active item in a group (e.g. The selected item in a segmented control). This can only be achieved by setting it programmatically.
UIControlStateHighlighted = it highlights the button with some flash(in button background) when the user taps.
UIControlStateSelected = it highlights nothing to that button.
From the official doc:
UIControlStateHighlighted Highlighted state of a control. A control
enters this state when a touch enters and exits during tracking and
when there is a touch up event. You can retrieve and set this value
through the highlighted property.
UIControlStateSelected Selected state of a control. For many controls,
this state has no effect on behavior or appearance. But other
subclasses (for example, the UISegmentedControl class) may have
different appearance depending on their selected state. You can
retrieve and set this value through the selected property.
Your button get highlighted in reaction of a touch event. It could then be on a selected state within a group (for segmented control).
Highlighted is typically applied transiently when the control is being touched, selected is a more permanent state. Imagine a checkbox type button which dimmed while it was being touched - dimming is highlighted, ticked is selected, unticked is unselected.
Typically you'd never set highlighted status manually as the system will be setting/unsettling it in response to touches, whereas selected is safer. This particularly applies to buttons.
I want my titleLabel text move a little down on button tap (i.e. I want to give different inset values for highlighted and default states).
I have custom button background images and the button goes down in highlighted state image but the text on it stands at the same place so it gives a bad effect and looks like the text is seperated from button.
Is there any way to solve this?
Thanks in advance
The easiest way to do this is to put your text on the button's background image.
If you can't do that for some reason you can try to add IBAction on Button down and adjust button.titleLabel.frame.
When my button is pressed, I don't want it's appearance to change. It changes blue while I touch it. I tried going into IB and unchecking "Highlighted adjusts image" but that didn't seem to change anything. I also have "Shows touch on highlight" unchecked. How do I disable this? Thanks for any input.
This solution isn't neat, but it does what you want.
Basically, you create an action method called deselect. And, depending on how little you want it to highlight, you hook several actions up to it. The easiest is just to hook up touch down, touch up inside and outside. However, if you want to insure that even if the user drags it doesn't get highlighted, you also hook it up to touch drag inside and outside.
The method should look like this:
- (IBAction)deselect:(id)sender {
[sender setHighlighted:NO];
}
Hope that helps!
When you touch a UIButton it hides for a fraction of second and then it executes its action. This fast "blink" is the feedback the user needs to know that the button has been clicked.
In the project I am doing, I need to select the button programmatically, as if the user had clicked it. In other words, the same behavior has the button had been clicked by the user... a fast blink and execution of its action.
Is this possible to do?
thanks for any help.
The change in the appearance of the button is effected by setting the button's highlighted property. The property is automatically set to YES when the user touches down on the button, and back to NO when she releases.
The highlighted property is writable, so you can set it YES yourself to simulate a touch down. You'll probably want to use +[NSTimer scheduledTimerWithTimeInterval:invocation:repeats:] to set it back to NO after a short interval.
It is pretty simple, and probably there is a better solution.
First, use images to your button, and when you have to fire the button, you just change the button's image in the normal state to the pressed image, and after that, replace it back to the original. You can simply do it with a timer.
how can i just change the color,of a button when i set the focus on the button in iphone.
I mean to say , for example we have 5 buttons, and i am just setting the focus on each of the button. i want those buttons to be higlighted with different color.
but when press or touch up inside the utton, the navigation is made to the respective forms, that is set for that button.
you can write method, for example, let it be
- (void) changeButtonState:(UIButton*) buttonToChange;
then you can call it in your onBtnClk method for button you need. in that method you can change image for your button's UIControlStateNormal mode. and if I understand right, you can use toolbar or tabbar instead of buttons.
Guess you have already asked this issue differently here..
But have you checked the answer?? You can use any of those methods at your will!
