UIStatusBarHidden

The first way is by adding a setting to your app’s info.plist file called UIStatusBarHidden. This is ideal for apps that should never display the status bar. Just follow these steps to change the setting:

1. Open your iPhone app’s info.plist file.

2. Command-click and select Add Row.

3. Select “Status bar is initially hidden” from the drop down that appears.

4. Check the checkbox that appears next to the new row.

You could also add this setting to your app’s info.plist file by opening it in a text editor and adding the following 2 XML tags inside the <dict> tag:

<dict>
	<key>UIStatusBarHidden</key>
	<true/>
	...

How to Do it With Code

If you need the status bar to appear and disappear at runtime, then you will need to use code to do so. You can hide the status bar with one line of code:

[[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO];

And to show it again, simply call the above line and pass “NO” into setStatusBarHidden instead of “YES”. You can also fade the status bar in and out by passing “YES” into the “animated” part of the message.
