Objective-c – iphone: Forcefully change orientation from portrait to landscape on navigation

iphonelandscapeobjective corientationuinavigationcontroller

Is there any way that we can Forcefully change app orientation from portrait to landscape while navigating ?

I have a requirement that while pushing controller from A to B. B should be in landscape but my A controller is in portrait.

In your ViewController-B add this lines of code in viewDidLoad:

  [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];

  float   angle = M_PI/2;  //rotate 180°, or 1 π radians
  self.view.layer.transform = CATransform3DMakeRotation(angle, 0, 0.0, 1.0);

This code is working fine if you are using navigation controller to move from A to B.

I have used this.

Hope this will help you.

Enjoy Coding :)

Html – Preserve HTML font-size when iPhone orientation changes from portrait to landscape

You can disable this behavior through the -webkit-text-size-adjust CSS property:

html {
    -webkit-text-size-adjust: 100%; /* Prevent font scaling in landscape while allowing user zoom */
}

The use of this property is described further in the Safari Web Content Guide.

Android – Force “portrait” orientation mode

Don't apply the orientation to the application element, instead you should apply the attribute to the activity element, and you must also set configChanges as noted below.

Example:

<activity
   android:screenOrientation="portrait"
   android:configChanges="orientation|keyboardHidden">
</activity>

This is applied in the manifest file AndroidManifest.xml.
