Question
We have an iPod app built with base SDK as 5.1. App has a
tabBarController with three tabs and each tab has a UIViewController to
load a different view.
The app works fine for iOS 6.1 and iOS 7 (3.5 inch display) simulator and
device but when we run the app on iOS 7 (4 inch display simulator) or device
we are getting black bars at the top and bottom of the view screen in all
three tabs. If anyone can suggest reason for this or some feasible solution to
this problem, it would be really helpful for us.
Thanks
Answer
First thing is that you must add the required default image for 4 inch screen
display. Check Properly in you project have image with name [email
protected] (640 × 1136 pixels)
This [email protected] is Necessary for Support app in 4 inch Screen display
Ones you add this image in to you working Project, Remove old Build from device or Simulatore, clear Project and re build and check Hope you issue will solve.
Edit:-
After fix the black Bar issue you can check the device like my answer Give here check this:-
[Detect device type](https://stackoverflow.com/questions/13139430/objective-c- how-detect-iphone-iphone5-and-ipad/13139561#13139561)
you have two choice if you can't use AutoLayout
First
Create two xib with same class one for 3.5 inch screen and one for 4 inch
screen set using macro with checking which screen appear.
Second
Set Self.view frame using macro with checking which screen appear.
There are also other methods you can use for set self.view frame as using
window frame or UIScreen
