I have come across the UITabBar touching area problem. Extra touching area (about 5 pixels) above the UITabBar is counted to be the UITabBar. All objects being put in that area will be blocked and UITabBar will react instead.
I found some people asked about the same question (the following links) and could not get answer.
Could someone please help?

I'm making an app for iphone. My layout can be the same for iphone 4, 4s, and 5 but for the iphone 4 and 4s the only thing that change is space between buttons. I finished my app and i arrange all storyboard to run well on iphone 5. Now i only have to tell that when the app running on iphone 4 and 4s i have to change the space between the buttons in some views to get all buttons inside screen. How i can do this? I can use auto layout i think but i dont use this. Its possible to help me? I do the things right, doing the design first for iphone 5 and now adapt for iphone 4 or im doing the things in the wrong way.
Regards
The IOS6 autolayout it's still a bit "wild" and it will also disable the IOS5 compatibility.
If you don't use autolayout, you can still set some rules in storyboard at size inspector, like tide you buttons to the top or the bottom of the view, so you can control where they go when the screen shrinks.
A better way is to add subviews to your view, and allow the subviews to shrink and expand (also # size inspector in storyboard). Then add your buttons to those subviews, tide them to the top, bottom, or let them untied/free if they are placed symmetrically inside the subview.
You can simulate quickly with the form factor button in storyboard (right-down corner) to see where the buttons go when you switch the sizes.
These methods require zero lines of code, but more work with the storyboard.
I am working on an app for iOS and I have to do a tab selection screen like the Google Chrome app for iPhone (I attached a screenshot). I searched a lot but I didn't found any similar control to use. As i can see, it groups some UIViews and use a UIScrollView to scroll, but maybe any of you could explain me better how this control works or have any solution.
Thank you!

Create Different UIViews with your controls.(One tab is equal to is on UIView)
Add this UIView's on UIScroll View.(This is optional. It's ok if you don't use the UIScrollView and add UIView on self.view
Implement the touch method on UIView.
When you get a particular UIView is touched change it's center position to Center of the screen.
Which will give you the UIView which is touched in foreground and rest of the Views in background.
Hope this will help you .........

I've got a navigationBar that does not auto-resize when rotating the device anymore. So the navigationBar keeps it's portrait height of 44 pixels and does not shrink down to 32 pixels. I'm using a custom UITabBarController subclass which initializes the UINavigationControllers and adds them to it's viewControllers array. Since I'm adding a UIImageView as a custom background to the navigationBar – which is being updated nicely when rotating – I always see the 12 pixel difference under my custom view. This differnce overlaps the UITableView also by the 12 pixels. So everything seems to be working fine – except the ordinary UINavigationBar. Did anyone ever have this issue and found a solution?
Thanks

Ok, this one answered my question and worked for me. But I'm still not sure if that's the 'right' solution since the templates do it right automatically.
Can Anyone tell me how to slide textview in iphone in the same manner as we do with images.
I am developing an application in which I want to side the TextView. I have 5 TextViews.
Can anyone help me with this.....
Thanx in advance...
You'll want a UIScrollView with paging enabled. Since with paging the view "stops on multiples of the view bounds" (according to the docs), you'd just line up your five text fields side-by-side, and make them the width of the visible area (the screen) inside a container view that sized to contain all 5.
Ive created a multiview application that uses multiple controllers to display and control views. The problem Im having is, when the simulator initially loads the view the header is partially covered by the bar at top of screen and the tool bar at the base is not touching the base of the screen. I used the Interface builder size attributes to control the view when the iphone rotates and it works perfectly. All smaps into place perfectly both in landscape and portrait mode AFTER a rotation but the problem is with the initial load before a rotation occurs.
Your thoughts a much appreciated.

I grappled with this issue for days and days--no amount of fiddling in IB worked.
Ultimately I got it to work by adding this line:
mainViewController.view.frame = window.screen.applicationFrame;
to the application:didFinishLaunchingWithOptions: method. (Where mainViewController is the primary UIViewController).
I've had issues with views being clipped by status, nav, and tab bars. I've fixed most of them by using the Simulated Metrics feature in Interface Builder. That way what your laying out in IB is a lot more accurate to what your actually going to get.
I ran into this issue too. Specifically, when displaying an ADBannerView, my whole view would shift and be under the status bar and leave a little empty space just the size of the status bar at the bottom of the iPhone screen. Here's how I solved it : (Adam's answer here helped me figure this out):
// In the function that displays an iAD Banner
CGRect contentFrame = self.view.bounds;
CGRect myStatusBarFrame = [[UIApplication sharedApplication] statusBarFrame];
CGFloat statusHeight = myStatusBarFrame.size.height;
// Set the view's origin to be under the status bar.
contentFrame.origin.y = statusHeight;
I needed to set the origin of my view to be below the Status bar, and that solved the issue for me.
The problem is that you're adding your controller "incorrectly" according to Apple docs (although IMHO Apple designed it badly - the default should be that you don't need to shift!)
if you're going to have a status bar, Apple requires that you "manually" shift all your controllers down by 20 pixels (more accurately, by the height of the statusbar - although that's always 20 pixels today, Apple lets you request the height at runtime, from the "statusBarFrame" property in UIApplication)
Apple's classes - e.g. UINavigationController / UITabBarController - automatically shift themselves down by 20 pixels when they're added to the screen. Both classes have a bug where they will do this shift even if they are not the main controller - so your app suddenly shifts down an extra 20 pixels, leaving 20 pixels of white space at top.
But, when they rotate, those classes often "get it right" and move back into place. Or vice versa.
c.f. this link for a much more detailed explanation of what's going on, and how to write your code the way Apple wants you to:
