My app draws a UIImageView with a photo to the screen every time a button is pressed.
The normal use case for my app would probably be about a dozen or so imageviews, but a user could potentially abuse it by continually pressing the "Add" button.
After about 50 or so the new images turn black. And after 100 or so the app freezes.
Now the majority of people using my app probably wont come close to these numbers, but through sheer abuse, they can crash the app. Is it my responsibility to design and implement failsafes that prevent the user from purposefully crashing the app?
I would argue that you should ensure that any software you produce meets the requirements of the user to the best of your ability. I suspect there is a memory allocation issue at hand here. In any case, I would argue it's better to find a bug and fix it rather than get complaints from users when they inexorably find them. If a bug affects the functionality of the program noticeably for the user, then I think it should be fixed. Cutting corners should be considered when adding extra features that may take more time than appropriate, not when fixing existing features.
I'm currently designing an app for the iPhone and I'm deciding on some features that imitate several native iPhone UI components and elements.
In my app, the user has to arrange several items on screen. Basically, they are free floating (not in a grid). In order to be able to move them, the user has to hold a finger on one of the items until all items start to "wobble". Just like on Springboard, when moving applications. Is it allowed to imitate this functionality?
Another function is the "split screen", as seen when adding an application to another application. The screen breaks open, showing a new group with the familiar textured background. In my app, some screens require a user decision by picking one out of four icons. I want to present this by using such a modal view over the main view, more or less like the "add to group" function of Springboard. Is this allowed?
I'm well aware that there are several programming questions related to my issue, but none of them covers whether apps are allowed if they include the functionality. Any help is greatly appreciated!
(On a side note, I read on HN today that Apple doesn't really answer questions to Support about app approval, therefore I ask here.)
I think the biggest problem you might have is the "free floating" functionality. There's a very big gray area as to what's accepted and, from my experience, you can't have an app with with seemingly floating windows like a desktop.
I can't see Apple having a problem with the Springboard functionality because the Facebook app has it. I would just try to make your own version and not try to reproduce the code.
Also, the Split Screen animation should be fine.
My 2 cents.
There is nothing in the guidelines about such functions not being allowed. I have submitted to apple an app recently with a wobble function like you mention and the reviewer did not mention anything about this being not allowed (The app was rejected for another reason which has to do with content licensing).
I have a question for the iPhone Development community. I am currently building my first app, and on two of my views I have some buttons. Sales and Marketing have requested that these buttons do nothing and have the title of “Feature Available in Pro Version” or have a title of an application but when touched, an UIAlertView is displayed stating “Feature Available in Pro Version”.
First off, I think this is wrong from a user interface and experience. Secondly and more importantly, I think this will cause a denial when I finish the application and send the app in to the App Store for approval. I have look into the iOS Human Interface Guidelines and really can not find whether this will be an issue or not. I would like to tell Sale and Marketing that their request is stupid and will not get the application approved and they need to stick to their jobs and quit trying to play programmer.
Any comments would be greatly appreciate.

Only display the UI for what your "Lite" version will do. Grayed out menu commands, "more track/car choices" you can see but not select, etc. makes your "Lite" version feel more like a commercial than a product, and an annoying and ineffective one at that.
...
It's important to follow these simple rules not only to create a better user experience, but also because your app will be returned to you by the App Review Team for modification if it is found to have time limits, incomplete functionality, or disabled functionality.
Come up with some better options for your clients. They are not trying to "play programmer", they are trying to market their product. Also, try to mitigate the risk of the app being rejected by getting it in a submittable state as soon as possible, or at least make sure that you have a plan B for the things that you suspect might fail to get approved.
It sounds like you're just looking for a stick to beat your sales and marketing team with - there are quite a few apps out there in the wild that exhibit precisely this behaviour, painful though this might be to you. (The buttons do something after all - they show a dialog.)
That said, it's hard to recommend a more pleasant alternative without knowing more about your app. (Does it have the concept of "levels" for example? If so, you could replace the buttons with a nicer "purchase the full app to unlock additional levels" style message.)
I am pretty sure this never used to be allowed. If you show user interface elements they have to be fully functional. I don't know in which document or agreement this is stated, though.
It also may not cause your app to be rejected, at least not initially. The app may be removed from the store at a later date, though.
Apple has been known to quickly reject apps for non-functional or grayed-out buttons, especially if these non-functional UI elements are just to advertise Full or Pro versions in Lite apps.
Apple has also been known to approve apps with a non-functional button or two (happened to one of my apps, got a bug report several weeks after the app had become available in the App store), but this is probably due to oversight, and not a policy that anyone should count on.
If you want an advertisement for your Pro version, make it look and act like a standard in-app advertisement, and not a misleading UI element. Serving house ads, or mostly (99%) house ads is a widely done practice.
Someone wants me to make an App, where the NavigationButton (usually top left) shall be put into the Tabbar (in this case leftmost Button of the Tabbar). I wonder if that might yield a possible rejection.
It reads in the Appstore Review Guidelines:
a) Apps that alter the functions of standard switches, such as the Volume Up/Down and Ring/Silent switches, will be rejected
-> Could that also include NavButtons?
Furthermore:
b) Apps that do not use system provided items, such as buttons and icons, correctly and as described in the Apple iPhone Human Interface Guidelines and the Apple iPad Human Interface Guidelines may be rejected
I do not know whether we crossed the line there.
What's your opinion on this?
I'd say it's a bit of a crap shoot and you need to weigh whether the feature is important enough to possibly delay your release by 2 weeks or more. If you submit it with the feature I would spend some time working on a different solution so that if it is rejected you can submit with the changes right away.
From personal experience, I had an app rejected because they didn't like the image I used on a button since that image was meant to convey "picking a contact for use in the app" not picking a contact to add information too. It was my opinion that this was a petty almost silly thing, but I corrected it and resubmitted. Both reviews took over 2 weeks. So it took me over 4 weeks to get approved.
Apple has gotten better about telling you what won't be accepted, etc. But different reviewers seem to have different opinions. I'd say the description of your feature is likely to be rejected, but you'll never know until you submit it.
Instapaper has a back button in a tab bar at the bottom. I think that if you decide to do this, you shouldn't use the system back button but create your own. Using the system button feels like a HIG violation.
iPhone OS 3.0 is being announced and previewed next week (March 17).
We all know the feature set users want. Copy/paste, MMS, Flash on iPhone, etc.
We'll see about those.
What I'm interested in what does the development community feel the SDK is missing, in need of, to make programming for the platform easier and more productive.
A more complete Interface Builder with support for custom palettes and all sorts of goodies like that.
Better control over the keyboard.
Better unit testing support. (Unit testing can be done, but only on the simulator, and it's very awkward to set up.)
Push notifications. Please.
A more accurate simulator, i.e. one with a more accurate set of frameworks.
The ability to easily build views like the Mail compose window.
For that matter, an in-application compose window.
A better way for apps to share data locally than by invoking URLs.
Access to the calendar, notes, mail (possibly read-only), and bookmarks (again, read-only) databases. Maybe even limited access to the iPod database—even just the ability to read song metadata and access and change the playing song would be helpful.
Some sort of middle ground between UILabel and UIWebView that allows for formatted text without a huge hassle.
More built-in toolbar icons.
The return of the "glass" button style that was in the beta SDK.
A few useful internal views, like UIProgressHUD, exposed.
And last but not least...
A pony.
An easy Javascript bookmarklet installation method for Mobile Safari. (OpenRadar: 1, 2)
UIWebView needs more of UIScrollView's properties and methods, such as contentOffset.
More configurability on some of the built-in behaviors and views, e.g. the button text on UITableViewCell's "Delete" button, or the styles and text of UIAlertSheet/UIAlertView buttons. (Some of these can be done today with undocumented calls, but I'd rather not rely on those.)
More flexibility from UINavigationController, such as the ability to push/pop views that selectively don't display the navigation bar but using the same animations and stack, or more customizability over the navigation bar button labels and behaviors.
The ability to restrict interface orientation per UIViewController, not just accept/reject changes via shouldAutorotate. E.g. I want my main content view to be autorotatable, but I want my navigation hierarchy and settings screens to always display in portrait, even if the content view was rotated to landscape.
libxml and its handy DOM XML parser instead of the SAX-based NSXMLParser.
libcurl w/SSL, or more options and functionality for NSURLConnection.
Ability to check whether a URL scheme is registered. This could be used for apps to detect whether other specific apps are installed, and enable functionality selectively, e.g. when Instapaper detects Tweetie is installed, it can offer a "Post with Tweetie" button. (Disclaimer: That was a plug. I make Instapaper.)
I'm sure I'll think of more, but overall, I'm very happy developing for the iPhone. I'm amazed at the quality and sophistication of the iPhone OS, the SDK, and the development tools given how incredibly young they all are.
I'm surprised no one has mentioned garbage collection yet. Objective-C 2.0 on the Mac supports optional garbage collection. I don't really see any reason it wouldn't work just fine on the iPhone as well and it would eliminate much of the tedium of having to explicitly release objects all over the place.
What I'm hoping most for is to allow iPhones to talk to each other either via Bluetooth or some other means. Granted, they can talk via Bonjour if they are on the same Wi-Fi network, but that's just not convenient enough in 2009. If I'm out with a friend and want to play a multi-player game we first have to find a Starbucks or whatever the heck to get on the same Wi-Fi network. Also, think of the ridiculous amount of social apps you could have if iPhones could talk to each other without needing Wi-Fi. Exchange business cards, flirt with the cute girl over there, etc.
Form a PURE programmers perspective, make XCode as helpful of an IDE as Eclipse or IntelliJ are in the Java world. There's so much time I waste on stupid stuff that the IDE could have found for me as I typed it.
I also don't understand why I can't color buttons without having to use images.
Better multitasking is absolutely key at this point. Android's got it, Palm's WebOS has it - both, it seems, in largely unrestricted and well-implemented fashion. Possibilities:
Push notifications with a good UI (message stack in addition to badging/sound/whatever - if they have to have an extra approval step so apps can't be obnoxious, so be it)
Multiple full processes (not possible with current OS, I realize, but then I've never seen a good explanation why the iPhone doesn't support virtual memory)
Smaller "background" versions of apps that can run in the background - no GUI and a significantly tighter memory constraint
A good mapping API. Let us access the Google Maps abstraction that the Maps application uses !
More Interface Builder goodness
Better simulator
Smart inbox. Incoming messages are routed to installed handlers based on type.
Synchronisation framework that simplifies syncing with desktop & Mobile Me.
Decent landscape support, without the multitude of bugs, especially for the camera picker. Better support for rotation and more control of it.
Access to EXIF data on images from the picker, so we can tell their location
Deeper access to the camera API, so that we are not rail-roaded into the standard photo taker / picker
Push notifications that can launch an application. (In lieu of full multi-tasking, which I don't think we'll get and which could be problematic.)
Better, more intuitive keyboard controls.
API for inter-application messaging.
Access to data from Calendar, iTunes, Mail, Notes and more (with user's permission)
A more accurate simulator, with, for example, ways to limit bandwidth, and use the Mac's camera to actually take a photo.
Phone-phone bluetooth for data exchange
Access to more of the views used by iPhone apps, e.g. the progress HUD, email "blobbing" mechanism for email addresses, thumbnail scrollers, HUD brought up in Photos app, and more.
Less sandboxing. It won't likely happen, but it would always be appreciated for an app to have slightly more power than they currently do (actual filesystem access, for example. even if it was read-only access, it would still allow for more interesting applications to exist).
EDIT: Also, access to the copy/paste API. But I hope that one is obvious to Apple.
My list:
More full-featured IB support as the Mac has
Inter-app Data transfer mechanism (could be C&P, but does not have to be)
Greatly improved camera API with deeper level of control and more flexibility
SDK access to bluetooth and more support for protocols
Real ObjectiveC framework around the address book like the Mac has today.
Warnings similar to the location warning when an app tries to access address book data.
I'm sure whatever they actually have prepared, there will be a few interesting twists.
Ability to send SMS messages without having to have launch the SMS client and have the user type the message.
Access to the raw camera data so that things can be done without having to take a picture and wait for it to save (like you can do with Android)
push notification so that you can launch tasks... would need to be user controllable.
A camera that can focus (I know... have to wait for the next iPhone for that... if they decide to put it in...)
A UIKit level drawing api.
We all know the feature set people want. Copy/Paste, MMS, Flash on iPhone, etc.
I would have thought those specific items were down the SO wish list (although it seems I'm wrong looking at the votes on this comment :-).
MMS is a pretty pointless app when you have eMail. Flash is not an OS issue - Flash could be delivered today.
I don't even want push notifications - they're just a patch, I want background apps. I also want fixes for all the broken APIs like Camera, video and landscape support. Support for CoreImage filters would be nice too but probably too much to wish for.
[[ABAddressBook sharedAddressBook] me] for being able to use the owner's Zip code, phone number, or whatever.
Ability to download files to local storage and sync them back to iTunes or your hard drive
Get EXIF data from photos
Pull all photos at once
Pull all contacts at once
Control screen brightness
Access to music in iPod section
Read access to email and text messages
Access to Safari cookies (so maybe I could make some kind of keep-me-logged-in app.)
fix table view in landscape mode
new camera API with direct access to the camera
distribution code signing automatically when uploading to the app store (instead of code signing in xcode)
ability to request more memory so users don't have to reboot their phones to get rid of background apps
A non-Mac based development envionment.
