Trying to use an info button in an iOS app. Wondering if anyone knows how to simulate the glow effect when you click on it.
See for example the weather or stocks apps in an iPhone; when you touch it, their is a glow highlight around the touch. Touch and hold to see it.
UIButton has a property called showsTouchWhenHighlighted. By default this is set to NO.
If you set it to yes you will get the glow effect when the button is highlighted.
You can set this in Interface builder by checking the "Shows Touch on Highlight" option.
Or you can do it in code with:
infoButton.showsTouchWhenHighlighted = YES;
This applies to all UIButtons, not just to info ones.

I know this might be a very basic question. But I am new to iOS.
I am building ontop of an existing project I found.I would like to add a scene( screen) which I would like to pop up before the main screen shows. I have tried many things, but no matter what I do, the first screen which pops up is the main screen.
Because I am new, please provide a detailed explanation.
And i am using a storyboard, i am not using a nib file which i would like to appear first.
If using Storyboard, just select the view controller and enable Is initial view controller option.

I want to create a drop up menu like this.
But I have no clue what it is called, so I can't look for it.
And by the way, are there others methods to create such a "more option"-menu? I know there is the UIPickerView, but if i have only 2 or 3 buttons to choose from it is fairly unnecessary to implement a whole pickview.
Thanks in advance!
David Wong is right, you always can use UIActionSheet for iOS 7 style drop menu, but if you want to use some cool custom controllers here's the list:
Drop menus
REMenu
LBActionSheet
NIDropDown
LHDropDownControl
kxmenu
Modal (cool ones)
KGModal
RNGridMenu
KNSemiModalViewController
But if you're just starting your journey of iOS development, you better stick with UIActionSheet.
Good luck!
That's a UIActionSheet
Just adds buttons and use the various show methods to bring it up. Don't forget to set the delegate to handle which button gets pressed.

I have a blank, transparent button which, when I drag left and right, and up and down, want a number to get incremented and decremented depending on how far away from the button the finger is.
Quite like the way the music app on the iPhone has the scrubbing feature, where you can get a more precise value?
This would require you to create a custom control heavily relying on gesture recognizers. I would advise you to search more on this topic.

I'm trying to make a uisegmentcontrol where the selected colour is something other than blue. Also I would like to change the style like the image below. Is any of these two things possible and how do you do it?
The easiest way to do this is with custom images using the UISegmentedControl instance methods such as setWidth:forSegmentAtIndex:, setImage:forSegmentAtIndex: and setDividerImage:forLeftSegmentState:rightSegmentState:barMetrics
You could also just use UIButtons to mimic the behavior of a UISegmentedControl

guys. I need to implement our designer's model. Here, he has moved the search bar to the bottom on the screen and whenever the keyboard appears it is moved to the top of the keyboard. Now I would like to keep the UISearchDisplayController to get all the filtering functionallity. But seems it's not possible to change the searchbar and keep it there. I could adjust the initial frame, but then when editmode comes. The bar is lifted to top of the screen. Has anybody done this before? Or maybe an alternative control that I could use?.
Thanks a lot.
You cannot use a UISearchDisplay in your case, you will need to implement the component yourself from scratch. The good thing is that you can use a UISearchBar for that, and just implemente yourself the behaviour using the delegate.
