I am looking for either the terminology or a reference on how to do this.
When you Successfully build a project on Xcode a nice, looking alert pops up. Like the one below:
I have found only one other question on how to recreate this for Mac OS. I want the iOS version. I want to use this alert to show a count down for a timer. I have the count down fully functional but I'm not sure of a good way to display. I think this would be ideal for it.

It's simply a view (UIView), with a transparent grey background color, rounded corners, and a light shadow. All of that can be readily be configured by straightforward view and layer properties in about three lines of code, and showing the view can be as simple as one line of code.

I am need create feature like in iOS "Photos" system app, when you are have a list of photos and use long press to image, this collection view with images exanded, all background is blurred and has appeared popover menu, how I can create it?
I am can detect long press on collection view and add some view behind, also I am try create blur effect but can't blur all behind particular cell.
This is image of this effect effect inside system app
Your screen shot shows a context menu interaction. Since this feature already exists at framework level, and since a collection view is ready to implement it for you, I suggest you just use it rather than trying to reinvent such a complicated thing for yourself.

how to know the default properties' values of UI controller in iOS?
Such as an alert view, I have Cancel/OK button on it, how could I know the Cancel/OK button's border color, border width, border's shadow?
And others, like button on navigation bar...
To sum up everything that's been said here - you can't get most of the data you need for the standard UI elements in iOS. You can however NSLog any of the UI elements and check out some of its properties. Be mindful of the fact that about 99% of the system UI elements have read-only properties meaning you can't change their look and feel directly (and honestly, you shouldn't).
Check out interesting projects like UI7Kit that allow you to port iOS 7 design to earlier iOS versions. Also Cocoa Controls are highly recommended for any UI customisation tweaks.

Currently i am trying to create a custom progress indicator in my ipad app.But currently there is no such controller available in ios sdk.
So how to create this ?
I have a really interesting vision of this - you need to create a UIImageView like the one on your picture and leave the areas that need to be highlighted transparent. You then put a blue UIView underneath it and using animation block you change its frame - kinda 'drag' it to the right - so it looks like it's filling the progress indicator. It's rather simple, give it a try.
Your best bet is to use a CAShapeLayer to draw out your loading bar and then animate accordingly.
Joe Conway (formerly of Big Nerd Ranch) created a circular progress bar which can be found here
I would recommend following along with the code he laid out for his project and mend it accordingly.

Hi I want to create bar chart application with slider control in ios. once my slider is changed my chart also changed and their datas also changed. I am new for this field. I dont know how and where to start in this application. If anybody knows please guide me or any other links send me. Advance in thanks.
There are various ways of achieving this.
You can use API's such as Core Plot to achieve your requirement. At the same time you can use Core Graphics & quartz Core to achieve it.
You should also check this out Bar Graphs in iOS app
i've made a hack
Make custom uiview for each bar accord to your input values.
set frame of each uiview(bar) according to input values.
there is no need of corePlot files if u want simple bar graph

I want to put a feedback form in a view in my IOS application.
There will be 2-3 smiley images. Initially they will be in grey color. When you tap one of them, it will be colored, and the rest stays grey. They will work like radio buttons in HTML.
And there will be 5 questions.
So, what is the best way to handle this feedback form in a native IOS application?
Thank you.
In my opinion the best and most simple way would be to do it with an embedded html page. This is great if you already have such a page for the web version.
Another way would be a custom made form in a xib, with custom buttons, but in order for you to actually receive that feedback, you would need to somehow send the data trough a scripted page (php, asp or whatever you like).
I've done similar things and I used the second suggestion I gave you but in my case it was different, because that form had to be presented over an existent view with animation and so on. What I would recommend you is the first one, with the web page.
I think you can use the xib to create the view with the question text and buttons for answer options. The buttons can have the smiley images as background image.
Then you can change the image for the smiley on button click for the button state selected. and may be have another button to confirm answer and move to next question that is refresh view with new question text.
Hope this helps.
