Tips for optimizing the page header for seamless performance on iOS6 and iOS7

Unfortunately, my application's header is being overlapped by the new iOS7 status bar while the navigation buttons are partially covered. The design looks flawless in iOS6, and I am hesitant to simply add margin/padding for iOS7 as it will compromise the appearance on the previous version.

Is there a seamless solution or an exclusive selector that can ensure compatibility with both systems?

My Attempts:

I have attempted to resolve the issue on iOS7 by adjusting the header margins (formatted with jQueryMobile), but this adjustment negatively impacts the display in iOS6. I believe there must be another workaround that I am overlooking, although my research efforts on Google have not yet yielded a solution.

Thank you in advance for any assistance provided.

Answer №1

If you're facing issues with the appearance of your Application on iOS6, worry not as there is a straightforward solution that will only affect ios7 devices.

#1 MainViewController.m

To implement this fix in your MainViewController.m, navigate to - (void)viewWillAppear:(BOOL)animated and insert the following if statement:

- (void)viewWillAppear:(BOOL)animated
{
    // View defaults to full size.  If you want to customize the view's size, or its subviews (e.g. webView),
    // you can do so here.
    //Lower screen 20px on ios 7
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
        CGRect viewBounds = [self.webView bounds];
        viewBounds.origin.y = 20;
        viewBounds.size.height = viewBounds.size.height - 20;
        self.webView.frame = viewBounds;
    }
    [super viewWillAppear:animated];
}

You can find more information about this issue from this source: iOS 7 status bar overlapping UI

or

#2 custom JS

function onDeviceReady() {
    if (parseFloat(window.device.version) === 7.0) {
          document.body.style.marginTop = "20px";
    }
}

Keep in mind that you will need the device plugin for the second method. However, personally, I found that #1 works seamlessly while the second approach did not yield the desired results.

After much experimentation, I finally settled on a solution for my JQuery Mobile multi-page setup. It wasn't as simple as just inserting a div at the beginning of the body-tag, especially since I needed the header color to extend behind the iOS7 status bar. Each page in my app had its own color scheme, ruling out the option of adding an extra div with a fixed background color. Instead, I opted to adjust the padding of elements with the role header when running on iOS7:

Javascript:

//accounting for transparent menubar in iOS7
if (parseFloat(window.device.version) === 7.0) {
    $('[data-role="header"]').addClass("ios7");
    $('.ui-btn-left').addClass("ios7-header-button");
}

css:

.ios7
{
    padding-top: 20px !important;
}

.ios7-header-button
{
    margin-top: 20px !important;
}

The additional padding for .ui-btn-left was necessary to prevent buttons from being partially hidden under the iOS7 status bar due to jQuery Mobile's formatting quirks.

I adjusted the header padding using HTML.

<div data-role="header" data-position="fixed" data-theme="b" style="padding-top:20px;">
    <h1 id="page_title">Title</h1>
</div>

In my JavaScript code, I implemented a margin for the button element.

$(".ui-btn-left").css("margin-top", "20px");
