Is it possible to create the layered structure (for eg. like the ones you see in photoshop) in an iPhone app.
Something like an image is being displayed and on top of it (a different layer) are controls like rotate...etc...
If yes, could anyone tell me how its done?
Any suggestion appreciated.
Thanks!
Sure this is possible. This is the basic principle of views and subviews. If you want to do such a thing, you should start reading a iPhone development book.

I am trying to implement the following kind of tabs into my Application. I have first tried it with creating buttons. So can anyone guide me how to create this kind of interface ?
I want to clarify that this are the groups & it will be dynamically created & it can be in any number.
Any suggestions & references will be highly appreciated.
Thanks in advance.
I've been implementing pretty much exactly what you are asking in an app im working on, i've uploaded the source files here. its pretty much plug-and-play, just make a TabView where you want your tabs and hook up the delegate methods. can swap out all the images with your own (my tabs were underneath something and not on top so they will look upside down initially for you).
Dont really have time to explain the inner workings of it all, but if you play around with the code im sure you will manage to customise it how you want. otherwise, just learn from it and implement your own.
edit: oh and there is some code that changes how the tabs look depending if iOS 7 or not, you will get an error when first importing it because i have a variable in my appDelegate isIOS7 which you can either implement in your app, or just take out all the relevant iOS 7 checks in the code
I need to make an iphone app like USA Free that's in App Store.
Can anybody, please, tell me what kind of app is this (window or view based) and how it is possible to make horizontal slide effect when changing views?
Thank you!
For transitions, take a look at http://developer.apple.com/library/ios/documentation/UIKit/Reference/UIView_Class/UIView/UIView.html#//apple_ref/occ/clm/UIView/transitionWithView:duration:options:animations:completion:
All apps contain one (or more) windows and views. You might want to start with the basic of creating an app. http://developer.apple.com/library/ios/referencelibrary/GettingStarted/Creating_an_iPhone_App/_index.html#//apple_ref/doc/uid/TP40007595
View based just means the project comes with a default class already setup. You can put anything you want in that class. Window based is just if you want to create all the classes your self. Theres not much difference, so it doesn't really matter which you choose as long a you know how to create the horizontal slide effect your going for.
I'm the design guy on a new iPhone project and am curious on the eat practices for the up elements in the iPhone 3-4 dev. I know the dpi is different between the two and am curious how best to handle this with the dev guys. Do I need to make 2 of everything or do we need to figure how to make vectors of things like buttons , backgrounds and other images?
Any help , examples and links would be awesome. My goal is to do the best for the app with asking for dumb things from the developer
Thanks
Your only option right now is to generate PDF images, then draw them manually with core graphics if you absolutely need vector graphics. Otherwise, you can wait for someone (including myself) to get something written third-party like, or you can just make two of everything.
You need to make 2 files.
Lets say you have an image that is 48x48 called Hello.png
the hires version will be 96x96 called Hello#2x.png
The iPhone will automatically determine which image to use.
Thank you, come again.
I want to implement a functionality similar to found in Pages app..i.e. text floating around images, image zooming etc.. I have been struggling with this part of my application but no success yet. Would be grateful if someone provides me with some pointers in this regard , like 'Which UIControl should I use?','Help in thinking logic' etc..
Thanx in advance.
Sounds like a fun app to develop.
Some Pointers:
Immediately off the bat, I would say look into creating your own Controls for the floating objects.
I would suggest tackling a smaller project, or maybe a few small to medium size projects. p
Try making a few apps with WinForms or WPF. Also look into XSL:FO.

There was a WWDC session that talked about iOS text. I don't think it's violating NDA to say this is going to be a very hard project. No, make that very, very, very hard.
You will probably need to do all UI yourself, and use Core Text for rendering of the text. (But I believe you need to draw selection, etc.) And do the layout yourself.
If you look at the Notes app on the iPad, you can see it uses all native iPhone controls, but they're "skinned" to look like a pad of paper. What's the best way to implement something similar to that? Could I use interface builder and simply change the background image for each of the controls, including the TableViews?
Thanks in advance for all your help! I'm going to continue researching this question right now.
This article from Dr Touch will probably come in handy: Stuff you learn from reverse engineering Notes.app
It's a little more complicated than that. My suggestion is manifold:
Hire a real designer to make the artwork.
Subclass whatever controls you want to skin, and handle this business directly in drawRect:. Interface Builder will not help you in this instance.
Consider drawing your controls programmatically instead of using images; a really cool thing would be to cache the programmatic drawings so that they only have to be performed once.
Best of luck!
