Personal Hotspot breaks UI layout

问题

When the personal Hotspot is activated and bar resizes itself to 40px, the view does not resize correctly. The bottom goes 20px below the screen instead of being resized.

I am using Auto Layout in all my View Controllers but even though my app UI breaks like the image shows below.

Any help would be great.!

Register this notification in your viewdidload

- (void)viewDidLoad {
    [super viewDidLoad];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(statusBarFrameWillChange:)name:UIApplicationWillChangeStatusBarFrameNotification object:nil];
}



  - (void)statusBarFrameWillChange:(NSNotification*)notification
{
     NSLog(@"STATUS BAR UPDATED");
int statusHeight = [UIApplication sharedApplication].statusBarFrame.size.height;
NSLog(@"status bar height  %d", statusHeight);
    // Here you can do your constraint adjustments accordingly
}

you can find a nice tutorial here (in swift) http://studyswift.blogspot.in/2015/12/adjust-ui-components-programmatically.html

You can check my previous answer iOS App layout is wrong with calling status bar

Technically same thing is happening here which is breaking your view's autolayout.
