How to hide the status bar programmatically in iOS 7?

Question

In ios7, how can I hide the statusbar programmatically? I am using XCode 4.6.1 (ios6.1) and I want to implement this in XCode itself.

Answer 1

Swift 4.1

step1. Set View controller-based status bar appearance in your info.plist to YES

step2. Type some code in your UIViewController, status bar will hide when you present the UIViewController.

private var statusBarIsHidden = false

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    statusBarIsHidden = true
    setNeedsStatusBarAppearanceUpdate()
}
override var prefersStatusBarHidden: Bool {
    return statusBarStatus
}
