I'm facing a Problem with my list . There is button naming List ..on click of it I'm showing list overlay, but due to more columns I have to make user to see it in landscape mode only..How would I achieve it ? I have made my whole Project orientation as Portrait . And I want to show this page in Landscape only...
The only thing I could think of is to create a landscape and portrait profile for that view and toggle them based on a listener for orientationchange.
I have a feeling though that will like the way that works even less. You may be better off rethinking that layout all together.
Good luck, Brad

I'm working on a iPhone app which shows an mobile webform in a UIWebView. I'm using a default iOS layout with a navigation and tab bar.
The mobile webform is displayed in a UIWebView in the white area. Since the webform has a lot of input fields, we really need as must space for it as possible. Because of this, we are planing to remove the tabs in the bottom. Over time, there will be more tabs/sections, so it is not a solution to just add a button for each section in the left side of the navigation bar. On a iPad a popover could easily be used to handle this.
Is there a standard iOS layout mechanism to handle this change of sections/views without using tabs?
You could do something long the lines of Path or the new Facebook app and have the "table of contents" behind the Navbar and the navbar slides away (along with the child view) to reveal it. When done right (ie smoothly) I think the effect is really cool.
This would also work great as you add more and more options, since the table could just scroll.
Here is a framework that might be you started: http://www.cocoacontrols.com/platforms/ios/controls/iiviewdeckcontroller
I would consider replacing the navigation bar's title with a control that lets you switch between tabs. You can assign the bar's titleView property to a control or a button and it will generally do the right thing.
If you're limited to 2-3 tabs, you could simply use a UISegmentedControl.
If you want more, you could use a button which, when tapped, pops up a view that allows you to select the view you want. This could be a modal table view, or you could slide up a UIPickerView from the bottom of the screen, similar to the keyboard.
I use this technique in an app of my own, screenshots here. Tapping the button cycles between views (in this case, I'm changing the contents of the table cells); tap-and-hold slides up a picker.
Another possibility would be to arrange your different forms on pages in a scroll view with a page control at the bottom, à la Weather. The best option, though, if you’re going to have a particularly long list and want to keep your screen real estate, is probably the FB/Path-style sidebar table.
I ended up using a UIActionSheet but I think it in other situations would be more stylish to use a controller like the IIViewDeckController.
I'm working on an app that needs many TabBar Items (6 or 7). I don't think users like to click the "More" button on TabBars, so I'm wondering how to make my own TabBar that slides from left to right, so one can easily access all the buttons on the tabbar without pressing "More."
Thanks!
I agree with the other answer that it's a bad idea from a design standpoint.
Nevertheless, the technical answer is that you can simply embed a UITabBar in a UIScrollView. If you set the tab bar's width and the scroll view's contentSize appropriately, the tab bar will be scrollable. You will probably want to turn off bouncing and scroll indicators.
I didn't try it with a UITarBarController.
Opinions on whether this is a good idea or not aside
A simple carousel should be fairly simple to implement from scratch using a UIScrollView with UIButton subviews. which will provide all the scroll mechanics for you
As a sample idea.
A UISCrollView which spans the width of the device.
N buttons across the scroll content pane
Restrict scroller to horizontal scrolling.
Provide selected and unselected images for the buttons
Create glue code to ensure only one button is selected at a time (like Radio buttons)
But I do agree with the other posters that its a bad UI idea. Id be thinking UIToolbar for this.
Apart from considerations about UX and UI guidelines, a way you can implement such thing is implementing a tab bar from scratch. You can even find a tutorial here for iOS5.
Actually, implementing a tab bar and a tab bar controller is not difficult as it may appear at first sight, but given the effort involved, you could also ask you what value this kind of design add to your app and to the user experience.
In any case, if you decide to go for this path (a scrollable tab bar), I would suggest to make it such that the user cannot be misguided into thinking it's a standard tab bar.
That's against about every design guideline ever written for iOS.
(I know that Gift Plan for iOS has a scrollable tab bar, but it never hides items from the user.)
The HOW to do it has been accepted,
MOBILE DESIGN PATTERNS are not cast in concrete - it is about what is appropriate for YOUR app.
It used to be that web pages scrolled vertically and side-scrolling was frowned on.
But the tablet has been a game changer - people EXPECT to swipe side to side.
A comment on one case when scrolling tab view is actually highly appropriate ..
(a) Look at xFeed in App Store
This has 10+ topics like News Sports ... , easy to scroll to topic and click takes you to RSS feeds under it.
This is truly convenient for user, and in my opinion appropriate.
The alternative is to go back and forth between a menu of some kind and the target view - which could be a 2nd option, but from a quick browse experience this is good.
(b) USA Today is another example - even on its main website, has the < > arrows to scroll between topics or you can click on tabs at top. Admittedly the tabs themselves don't scroll, but you get the idea. The entire site, and the mobile experience for USA Today is strongly optimized around side swipeing between chapters.
(c) Presentations and content sites have come to be side scrolling as well.
(d) FINALLY on a Human Happiness viewpoint! People WANT TO TOUCH and PLAY with their mobile stuff. Not just tap!
So mobile touch is quite happy here. One more thing to swipe and slide :)
Here is a link of project with custom scrollable tab bar:
github - scrollable tab bar by BananaDev
It's free and provides a wide variety of customization options allowing you to fully change control.
I'm trying to make and iOS app with both portrait and landscape views, but if I open it and change the orientation to Landscape, some buttons got offscreen, after going to IB and reordering the buttons, in Portrait they go off screen.
After googling, I dont have ANY ideia how to 'change' views according to orientation.
Could you guys give me some help?
Ah, also, Apple Support Documents seems pretty useless to me :P
Thanks!
There a method - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{}
which is useful in such cases.
You should change autosizing properties in IB (they're in the same place where frame size is) or change autoresizingMask properties of your inner views and controls programmatically. This controls what happens to the elements of your screen after it gets resized (for example when the screen is rotating). You can glue your components to left or right or both, top or bottom or both and similar. Play with it, it's pretty powerful and you don't need any code for that if what they can do is enough.
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.
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.
alt text http://www.agilitesoftware.com/SpringboardExample.png
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.
