Can anyone explain what is the life cycle process of iPhone? i.e from the start to end of the application life cycle.
See also This post on Cocoanetics that present a very useful flowchart explaining the different calls to the AppDelegate methods during the app life cycle:
here is diagram image for understand Life Cycle (iPhone / Android)
Edit: Here is the more detailed information from Apple Docs.
Part 1:
Part 2:
Reference
Also this one is for View Controller Life Cycle methods
There's another simpler one in ios developer's cookbook
If you want to something more detail ,you can read the official document delivered by apple

I'm creating an alarm app. How to do the alarm app as same in default iphone alarm?
I want to do the same as in the image.
Please give me a suggestion I'm new to iOS.
SampleImage
This are called Table Views and you can find how to work with them here
Then you need to learn how to work with Custom Table View Cells you can find it here
UI is easy and you can find some tutorials for it on this site
The only most important thing that you need to know about is audio sessions. Please check the audio session programming guide
Audio session is important because you need to manage your alarm when app is in background/some other sound is playing like cases.

From the UIWebView, The UIWebView class should not be subclassed.
I just want to know why. There is no more detail about this.
Because I met a memory out issue in my project, which create one extended UIWebView, which could cause memory out issue. Otherwise, just create the UIWebView instance will not cause the issue.
That is why I want to address this problem and try to analyze more.
Thanks for the guy to give some comments in terms of the design pattern with MVC.
I hope to close this once get some comments for memory management.
Thanks,
iOS development works on MVC concept and V part which is View should be as generic as possible. If you write a custom view, when the model changes the view has to change as well. It becomes interlinked..This means the view cannot be reused, especially when a new UI comes out..Better to put the code in the controller portion...Key: Keep the view as generic as possible..

There is some tutorial or sample of iOS 5.1 integration with Facebook? I've tried the one on Facebook developer site, but I get error on retaining the properties https://developers.facebook.com/docs/mobile/ios/build/. I'm really fresh on IOS, so if you can help I would be grateful!
You're most likely getting an error using retain because when you created your new project Xcode asked you if you would like to use Automatic Reference Counting (ARC) and you selected the check box (I think it is selected by default). ARC disallows manual memory management calls such as retain. Upload the line in question and I'll edit this post to show you how to fix it.

I've already released several app-books for children and the number of books is quite big.
What I want to do is create a book-stand (like news stand in iOS) and get the book together.
I think there is no way to get my apps in one app(the book-stand...) so I'm trying to remake all my previous work(the app-books) and create new app(book stand).
However, each app-book has its own interactive objects so I have no idea how to do this.
Is there any good document or any tips for this?
Can your books be made via iBooks Author? How are they interactive? If you have to go down the custom store route, I would look at epub and HTML5.
Check out the Baker Framework or HPub. Also check out various interactive PDF SDKs out there.

Is there a guide / book about custom control development for iOS? All the books I've found don't go beyond using UIKit builtin controls.
As #petert wrote, Cocoa Controls is a great resource, but my favourite is by far iDev Recipes (even though it's not updating that often anymore). Check also http://maniacdev.com/, many open source libraries/projects can be found and it gets updated regularly. Ray Wenderlich has also many nice tutorials - scroll down to "Graphics and Animation".
EDIT: I just saw that #Jano suggests idevrecipes as well, sorry for doulbe posting
