UIApplication statusBarFrame example ios


[UIApplication statusBarFrame]

The frame rectangle defining the area of the status bar. (read-only)
@property(nonatomic, readonly) CGRect statusBarFrame
Discussion
The value of this property is CGRectZero if the status bar is hidden.
Example of [UIApplication statusBarFrame]
- (CGRect)statusBarFrameViewRect:(UIView*)view 
{
    CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame];

    CGRect statusBarWindowRect = [view.window convertRect:statusBarFrame fromWindow: nil];

    CGRect statusBarViewRect = [view convertRect:statusBarWindowRect fromView: nil];

    return statusBarViewRect;
}
Example of [UIApplication statusBarFrame]
+(CGSize) sizeInOrientation:(UIInterfaceOrientation)orientation
{
    CGSize size = [UIScreen mainScreen].bounds.size;
    UIApplication *application = [UIApplication sharedApplication];
    if (UIInterfaceOrientationIsLandscape(orientation))
    {
        size = CGSizeMake(size.height, size.width);
    }
    if (application.statusBarHidden == NO)
    {
        size.height -= MIN(application.statusBarFrame.size.width, application.statusBarFrame.size.height);
    }
    return size;
}

Example of [UIApplication statusBarFrame]
 CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame];

    // delta is the amount by which the nav bar will be moved
    delta = statusBarFrame.size.height + self.navigationController.navigationBar.frame.size.height;

    if(statusBarFrame.size.height>20) { // in-call
        animationDuration = 0.5;
    }
    else { // normal status bar 
        animationDuration = 0.6;
    }

    // hide status bar
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];

    // hide nav bar
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration:animationDuration];

    self.navigationController.navigationBar.frame = CGRectOffset(self.navigationController.navigationBar.frame, 0.0, -delta);

    [UIView commitAnimations];
