UIScreen and ios8UIScreen in ios8
Java code

Let orientation: UIInterfaceOrientation = UIApplication. sharedApplication (). statusBarOrientation

Println ("Currently landscape:" + (orientation = UIInterfaceOrientation. LandscapeLeft | orientation = UIInterfaceOrientation. LandscapeRight )? "YES": "NO "))

Println ("UIScreen. mainScreen (). bounds: \ (UIScreen. mainScreen (). bounds )")

Println ("UIScreen. mainScreen (). applicationFrame: \ (UIScreen. mainScreen (). applicationFrame )")

   let orientation: UIInterfaceOrientation = UIApplication.sharedApplication().statusBarOrientation        println("Currently landscape: " + ((orientation == UIInterfaceOrientation.LandscapeLeft||orientation == UIInterfaceOrientation.LandscapeRight) ?"YES":"NO"))        println("UIScreen.mainScreen().bounds: \(UIScreen.mainScreen().bounds)")        println("UIScreen.mainScreen().applicationFrame: \(UIScreen.mainScreen().applicationFrame)")

Output in ios7:

Currently landscape: NO

UIScreen. mainScreen (). bounds: (0.0, 0.0, 320.0, 568.0)

UIScreen. mainScreen (). applicationFrame: (0.0, 20.0, 320.0, 548.0)

Currently landscape: YES

UIScreen. mainScreen (). bounds: (0.0, 0.0, 320.0, 568.0)

 

UIScreen. mainScreen (). applicationFrame: (20.0, 0.0, 300.0, 568.0)

 

Output in ios8:

Currently landscape: NO

UIScreen. mainScreen (). bounds: (0.0, 0.0, 320.0, 568.0)

UIScreen. mainScreen (). applicationFrame: (0.0, 20.0, 320.0, 548.0)

Currently landscape: YES

UIScreen. mainScreen (). bounds: (0.0, 0.0, 568.0, 320.0)

UIScreen. mainScreen (). applicationFrame: (0.0, 0.0, 568.0, 320.0)

 

Conclusion:

1. In ios7, UIScreen. mainScreen (). bounds is a fixed value. In ios8. its value changes with the landscape and landscape!

In order to get the original effect in ios8:

Java code

+ (CGSize) screenSize {

CGSize screenSize = [UIScreen mainScreen]. bounds. size;

Return CGSizeMake (MIN (screenSize. width, screenSize. height), MAX (screenSize. width, screenSize. height ));

}

+ (CGSize)screenSize {    CGSize screenSize = [UIScreen mainScreen].bounds.size;    return CGSizeMake(MIN(screenSize.width, screenSize.height), MAX(screenSize.width, screenSize.height));}

 

2,

Two attributes are added to ios8:

NativeBounds: screen pixels, which do not change horizontally or vertically!

NativeScale: 1 (non retina)/2 (retina)/3 (retina hd)

Ios8 output:

Currently landscape: YES

UIScreen. mainScreen (). bounds: (0.0, 0.0, 568.0, 320.0)

UIScreen. mainScreen (). applicationFrame: (0.0, 20.0, 568.0, 300.0)

UIScreen. mainScreen (). nativeBounds: (0.0, 0.0, 640.0, 1136.0)

UIScreen. mainScreen (). nativeScale: 2.0

Currently landscape: NO

UIScreen. mainScreen (). bounds: (0.0, 0.0, 320.0, 568.0)

UIScreen. mainScreen (). applicationFrame: (0.0, 20.0, 320.0, 548.0)

UIScreen. mainScreen (). nativeBounds: (0.0, 0.0, 640.0, 1136.0)

 

UIScreen. mainScreen (). nativeScale: 2.0

 

3. The output value of UIScreen. mainScreen (). applicationFrame indicates that the statusbar of ios8 is hidden by default. You can

View controller-based status bar appearance values are different

 

Java code

UIApplication. sharedApplication (). setStatusBarHidden (false, withAnimation: UIStatusBarAnimation. None)

UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: UIStatusBarAnimation.None)

 

Or

Java code

Override func prefersStatusBarHidden ()-> Bool {

Return false

}

  override func prefersStatusBarHidden() -> Bool {        return false     }

Display landscape statusbar
