I'm following this guide to create some animations to my app and thought about writing a very light not distracting animation to my tab bar. I've searched apple guidelines but didn't saw anything against it, yet, I don't think I've ever seen an app doing something similar. Is that because it's not allowed or is there another reason I'm missing?
Any one knows an app that does something similar?
I'm using a simple slide in/out effect for the tab bar in my App.
No problems in the review.
The code I'm using is at https://stackoverflow.com/a/5272497/725594

In my app I have a webview that is used solely for displaying the facebook page.
However, the client does not want the top blue bar of facebook to appear; he wants to hide it.
Is there a way to do this?
The bar is 45 pixels, so what I did is I moved the UIWebView in IB in such a way that its top 45 pixels are behind my navigation bar (thus not appearing).
However, this is not an ideal solution, as the user can see that content when he scrolls up, before bouncing. He can see but not touch it, which will be frustrating for some users.
I tried turning the bouncing off, but then the UI becomes too rigid, and not fluid.
I looked up in Google and Stackoverflow for a couple of hours but didn`t find a solution.
Thanks a lot!
You'll have to edit the HTML/CSS of the page itself to hide the HTML elements in question, probably using regular expressions, and feed it into your UIWebView with loadHTMLString:baseURL:.
I've done similar manipulating before and it works, but... it's a different ballgame when the webpages in question don't belong to you. Any time Facebook updates their layout, your app behavior might change until you have time to get an app update approved. Clients want what they want, but make sure your client knows what he's asking for!
First test out the javascript code used to hide whatever elements in the webpage and then pass up to stringByEvaluatingJavaScriptFromString of UIWebView to run it.
I thought that it was not allowed to customize the taskbar on the iPhone. However, I noticed this app called iHandy Tip Calculator which replaces the battery icon with a fast switch icon, that pops up a view as shown. How is this allowed, and if so how can I be doing something different?
If you run the app on an iPad, you'll see, how they do it: they are overlaying the normal status bar. Also note, that the screenshots in the app store don't show this feature. I assume, they were fearing to get rejected and disabled the overlay for the screenshots.
Apps from this developer iHandy incorporate this into the status bar, but I've never seen another company do this. I am surprised that the status bar is able to be modified in this way in any event.
My question on apple.stackexchange is posted over here:
https://apple.stackexchange.com/questions/71969/what-is-the-meaning-of-this-status-bar-icon
It is possible to create your own statusbar and "simulate" the network status and battery life etc in a 'full-screen' app. But apple doesn't allow it, but this might be one that 'slipped through' just like Gaz_Edge said.
You are correct. You are not suppose to be able to modify the 'springboard'. Apple normally refuse apps that do anything that modifies it. Maybe this one slipped through the net?
I just downloaded the latest version of iHandy Level (version 1.62.0) on an iPhone 5 running iOS 6 but don't see the icon (it's within the app rather than in the status bar). (And the status bar is hidden.)
I was curious to see if they actually hid the status bar and created their own custom status bar. If that was the case, you'd be able to tell because when you swipe down from the top for notification center, it would first show a little tab and then you'd have to swipe again to pull down the menu.
Guessing maybe they removed this functionality at Apple's request.
If anyone still has a version that shows it, please let us know if it shows the tab when you swipe for notification center. If not, they likely found some private api to allow them to replace the battery icon (which would be interesting).
I've got a tabbed iPad application with just about each tab running a UIWebView. I'm getting all sorts of callbacks, like when a user tries to leave the corporate site (which only displays the company site to users). In this case, I pop up a "toast" style window that tells them to click a button to open the page in Safari. I also pop it up with a spinner and no text to indicate that a page is loading. The approximate look that I'm going for is used in lots of applications, but you can see it best when changing the volume on the iPhone or iPad. It's just a translucent rounded square that fades in and out.
Right now I've got it implemented on one of my tabs, and I did it by creating the objects (a spinner, a label, and a UIImage with the square) and then programmatically hiding and showing them using [UIView beginAnimations] and changing the label's text. It works perfectly but I've got these nagging things hovering over my interface in Xcode, and it takes a lot of setup to accomplish if I wanted it to be in another tab, which I do. I can't help but think that there's a better way to accomplish this. I thought about making and adding a subview, but that would leave a white background to the toast. What I'm thinking is creating some sort of object that I can allocate in a tab's view controller whenever it's needed.
What are your guys ideas, or have you done this in the past? I see it in a lot of prominent applications, like Reeder, so I'm sure it's been done more eloquently than I have done it.
Matt Gallagher has a great class called LoadingView here Showing message over iPhone Keyboard. I use it.
MBProgressHUD is a popular library for this, as well.
Please see the youtube:

notice that the 0:35 , the iPad bottom have a thin photo bar. Is it a private API or I need to create my own or Which UI Element will it be? Thz.
That's definitely a custom job. However, it's basically a UIToolbar with a fancy slider on it. You can easily make the toolbar using Interface Builder, and you could take a simple stab at the slider by taking a regular UISlider and giving it some replacement images for its track, thumb, etc. See the documentation on UISlider.
If that doesn't quite work, then you're going to have to get down and dirty in UIControl code and make on yourself from scratch (or hope and pray that someone has written an open source version already).
I am trying to design a feature in my application for the iPhone that simulates the Springboard feature (Main menu of the iPhone that allows you to view more apps), or the way Weather application works that allows you to flip between views.
Does anyone have any samples of this how I would go about doing this. It's seems very trivial but I am wondering if I am missing something that is already available either as an Apple example or someone who did a tutorial on this.
The image below show how the user would use it.

As they slide their finger to the right (or left) the other image would begin to show up. And it would animate smoothly. The faster you swiped your finger the faster it would move to the next view.
Update: The other feature is that it should mimic the same feel when you slide your hand across the display that is snaps to the current view into place. It should not keep sliding across if there is more than 1 view to the direction you swiping your finger.
I've seen other applications use this so that is why I am asking.
This is accomplished using the UIScrollView with the pagingEnabled property set to true. Just add each of your views, adjust the contentSize, and it will automatically "page" to the width of the screen across the content.
There is a sample app (with code) with exactly this functionality on the iPhone developer site on Apple.com (I believe it's called "PageControl".) - I'd suggest checking it out.
d.
I'm writing an app that uses a similar UI. As NilObject recommended, we're using a UIScrollView with pagingEnabled=YES.
You may also be interested in this example code involving just two child views. I'm trying it out now; it's an interesting technique but I've had to write some additional special-casing code for some odd situations that resulted.
There's also another question on this site that asks about creating a grid of icons like the home screen.
I would check out Joe Hewitt's code from the Three20 project for this. It provides a nice interface and further refinement of the UIScrollView implemented as TTScrollView and TTScrollViewDelegate, TTScrollViewDataSource.
