Black bars showing when starting the application on iOS 7 (4-inch retina display)

Question

We have an iPod app built with an SDK base like 5.1. An application has a tabBarController with three tabs, and each tab has a UIViewController to load a different view.

The application works fine for the simulator and device iOS 6.1 and iOS 7 (3.5-inch display), but when you start the application iOS 7 (simulator 4-inch display) or a device on which we get black bars at the top and bottom of the viewing screen at all three tabs. If someone can suggest a reason for this or a possible solution to this problem, it would be really useful for us.

Answer 1

First of all, you must add the required default image for the 4-inch screen. Make sure you have an image in your project with the name [e-mail] (640 × 1136 pixels)

This [e-mail] is required to support the application on a 4-inch display screen.

You add this image to your working project, delete the old assembly from the device or Simulatore, clear the project and restore the assembly and check. I hope you solve the problem.

Edit: -

After fixing the problem with the black bar, you can check the device as my answer. Let me check this out here: -

Detect device type

you have two options if you cannot use AutoLayout

First

Create two xib with the same class for the 3.5-inch screen and one for the 4-inch screen using a macro to check which screen appears.

Second

Set the Self.view frame using a macro, checking which screen appears.

There are other methods that you can use to set the self.view frame using a window or UIScreen frame.

Answer 2

My problem was that I accidentally deleted the value found here:

I added LaunchScreen back and made sure there was LaunchScreen.xib. Perhaps this will help some others.

Answer 3

I had the same problem: black bars at the top and bottom. This was simply resolved by setting the drop-down list in “Application Icons and Launching Images” on Main_iPhone:

Application screen and screenshots

Answer 4

Same problem. For ios 8.1, check if the startup file is configured correctly in the main configuration window. For ios 7.1, make sure the startup image contains a 640x1136 image.

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

Answer 5

Mine was even easier to fix. I just typed LaunchScreen into the Launch Screen File field .

• Click Project file in Project Navigator
• Click General tab
• Enter "LaunchScreen" in the Launch Screen File field
• Save

I had the same problem. I just added a launch image and it worked for me.
