Black bars showing when running app on iOS 7 (4 inch retina display)

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 1

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 Default-568h@2x.png (640 × 1136 pixels)

This Default-568h@2x.png 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

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

My problem was I accidentally deleted the value found here:

I added back LaunchScreen, and made sure there was a LaunchScreen.xib. Maybe it will help some others.

Answer 3

Ive had the same problem - black bars at the top and bottom. It was simply solved by setting the drop down in "App Icons and Launch Images" to Main_iPhone:

App Icons and Launch Images Screen Shot

Answer 4

Same problem. For ios 8.1 check whether the launch file is configured properly in the main configuration window. For ios 7.1 ensure that the launch image contains 640x1136 image.

This will clear the black bar problem on both ios when running in simulator.
