No, this is done at the OS level, and webpage doesn&#39;t get any callback

See [this summary of safari changes in iOS7 that might cause problems to your website][1] (including this swipe gesture)

You can&#39;t disable it directly, but the native swipe back only happens if there is something in the browser history.

It won&#39;t work in every case, but if you have a single page web app opened in a new tab, you can prevent it from adding to the history by using

    window.history.replaceState(null, null, &quot;#&quot; + url)

instead of pushState or 
 
    document.location.hash = url

I had to use 2 approaches:

**1) CSS only fix for Chrome/Firefox**

&lt;!-- language: lang-css --&gt;

    html, body {
        overscroll-behavior-x: none;
    }

**2) JavaScript fix for Safari**

&lt;!-- language: lang-js --&gt;

    if (window.safari) {
        history.pushState(null, null, location.href);
        window.onpopstate = function(event) {
            history.go(1);
        };
    }

Over time, Safari will implement [overscroll-behavior-x](https://developer.mozilla.org/en-US/docs/Web/CSS/overscroll-behavior-x) and we&#39;ll be able to remove the JS hack


I want to put the text of a radio button on the left not on the right

I found this solution

            &lt;RadioGroup

For some web pages we use the swipe left and right functionality of iPhone to pull up the menus. 
Now with iOS7, they have introduced the ability to go back and forward to previous and next pages of browser history on swipe left and right motions.

But is there a way to disable it for specific pages so as to not have conflicting behavior on the swipe actions?

iOS 7 - is there a way to disable the swipe back and forward functionality in Safari?

I am getting this error only in iOS 7 and the application crashed. 
In iOS 6, I never get any error, just once of memory warning when opening the camera.

    Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.

Here is what I am doing.

    imagePicker = [[UIImagePickerController alloc] init];
    [imagePicker setDelegate:self];
    [imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
    [imagePicker setAllowsEditing:YES];
            
    [self presentModalViewController:imagePicker animated:YES];

I did tried to delay the `presentModalViewController`, but I am still getting the same message. After few seconds (7-10), the application crashed.

This error is only present in iOS 7. 

Anybody has the clue?

With the 64 bit version of iOS we can&#39;t use `%d` and `%u` anymore to format `NSInteger` and `NSUInteger`. Because for 64 bit those are typedef&#39;d to `long` and `unsigned long` instead of `int` and `unsigned int`.

So Xcode will throw warnings if you try to format NSInteger with %d. Xcode is nice to us and offers an replacement for those two cases, which consists of a l-prefixed format specifier and a typecast to long. Then our code basically looks like this:

    NSLog(@&quot;%ld&quot;, (long)i);
    NSLog(@&quot;%lu&quot;, (unsigned long)u);

Which, if you ask me, is a pain in the eye. 


A couple of days ago someone at Twitter mentioned the format specifiers `%zd` to format signed variables and `%tu` to format unsigned variables on 32 and 64 bit plattforms. 

    NSLog(@&quot;%zd&quot;, i);
    NSLog(@&quot;%tu&quot;, u);

Which seems to work. And which I like more than typecasting. 

But I honestly have no idea why those work. Right now both are basically magic values for me.  
 
I did a bit of research and figured out that the `z` prefix means that the following format specifier has the same size as `size_t`. But I have absolutely no idea what the prefix `t` means. So I have two questions:

What exactly do `%zd` and `%tu` mean?

And is it safe to use `%zd` and `%tu` instead of Apples suggestion to typecast to long?

---


*I am aware of similar questions and Apples 64-Bit Transition guides, which all recommend the `%lu (unsigned long)` approach. I am asking for an alternative to type casting.* 

Alternatives to type casting when formatting NS(U)Integer on 32 and 64 bit architectures?

How can I get the right coloring for my translucent navigation bars in iOS 7? The navigation bar just adjusts the given color to a much brighter one. Changing brightness or saturation of the color also doesn&#180;t deliver the right result.

Anyone having the same trouble? It seems to work somehow, looking at Facebook: they&#180;re having their colors and translucent navigation bars.

Edit: Just to make it clear: I need the Bar to be translucent, not transparent (with some alpha), not solid! http://en.wikipedia.org/wiki/Transparency_and_translucency 

Edit: Now posted to Apple BugReporter

Get the right color in iOS7 translucent navigation bar

I know that are already some [stackoverflow][1] [questions][2] that say how to change the status bar for all view controllers. I am currently changing the color of status bar this way:
    
    if(IS_IOS7)
        [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

In the `application:DidFinishLaunching`

Additionally, I have changed the value of `UIViewControllerBasedStatusBarAppearance` in the plist to `NO`. However, in the splashscreen it stills shows the status bar text with the black color. 

Is it possible to change the color of the status bar text color **in the splash screen**?

Changing the status bar text color in splash screen iOS 7

**iOS 7.1 UPDATE**: Looks like the workaround for modifying the alpha channel in the UINavigationBar has been ignored in this update. Right now, the best solution seems to be to just &#39;deal with it&#39; and hope that whatever color you choose can render a translucent effect. I am still looking into ways of getting around this.

--- 

**iOS 7.0.3 UPDATE**: The [GitHub library we created](https://github.com/croberts22/CRNavigationController) has been updated to slightly work around this issue when using iOS 7.0.3. Unfortunately, there is no magic formula to support both colors created in iOS 7.0.2 and earlier and iOS 7.0.3. Seems like Apple improved the saturation, but at the cost of opacity (since the blurred translucency is dependant on the opacity level). I, along with a few others, are working on creating a much better fix for this.

---

I&#39;m sure many people have already come across the problem where iOS 7 tends to desaturate the color of a UINavigationBar that is translucent.

My goal is to achieve a UINavigationBar with this tint color, but translucent:

![UINavigationBar, Opaque][1]


However, with translucency, I&#39;m getting this. The background view is white, which I understand will make this view a bit lighter:

![UINavigationBar, Translucent][2]

Is there any way to achieve the original color while still having translucency? I&#39;ve noticed Facebook has been able to get their bar to be their rich, blue color, as displayed here:

![Facebook UINavigationBar, Translucent][3]

..so I know there has to be some way. Background views obviously make a difference here, but most of their content is also gray/white. It seems that regardless of whatever bar tint color you put in, you are unable to get vivid colors under translucency.

**Updated with solution.**

Here&#39;s the solution that I ended up coming up with. I took [aprato](https://stackoverflow.com/a/18906759/692051)&#39;s solution and then encompassed the custom `UINavigationBar` within a `UINavigationController` subclass. [I have created a repository that has this implementation listed below, along with an example app](https://github.com/croberts22/CRNavigationController).

        [super setBarTintColor:barTintColor];
        if (self.colorLayer == nil) {
            self.colorLayer = [CALayer layer];
            self.colorLayer.opacity = kDefaultColorLayerOpacity;
            [self.layer addSublayer:self.colorLayer];
        }
        self.colorLayer.backgroundColor = barTintColor.CGColor;
    }
 
    - (void)layoutSubviews {
        [super layoutSubviews];
        if (self.colorLayer != nil) {
            self.colorLayer.frame = CGRectMake(0, 0 - kSpaceToCoverStatusBars, CGRectGetWidth(self.bounds), CGRectGetHeight(self.bounds) + kSpaceToCoverStatusBars);

Achieving bright, vivid colors for an iOS 7 translucent UINavigationBar

We&#39;re seeing issues with a web app that has a height of 100% on Safari in iOS 7. It appears that the window.innerHeight (672px) doesn&#39;t match window.outerHeight (692px), but only in landscape mode. What ends up happening is that in an app with 100% height on the body, you get 20px of extra space. This means that when a user swipes up on our app, the navigation elements get pulled behind the browser chrome. It also means that any absolutely positioned elements that are at the bottom of the screen end up being 20px off.

This issue was also outlined in this question here:
https://stackoverflow.com/questions/18855642/ios-7-css-html-height-100-692px

And can be seen in this ambiguous screenshot:
![iOS 7 Safari outerHeight issue][1]

What we&#39;re trying to do is hack around this so that until Apple fixes the bug, we don&#39;t have to worry about it.

One way of doing this is to absolutely position the body only in iOS 7, but this pretty much puts the extra 20px at the top of the page instead of the bottom:

    body {
        position: absolute;
        bottom: 0;
        height: 672px !important;
    }

Any help with forcing outerHeight to match innerHeight, or hacking around it so that our users can&#39;t see this issue would be much appreciated.

iOS 7 iPad Safari Landscape innerHeight/outerHeight layout issue

I am using an HTML file input like this: 

    &lt;input type=&quot;file&quot; accept=&quot;video/*&quot;&gt; 

to allow my users to upload videos to my site. This works as expected in all modern browsers (only permitting the user to select video files) except Safari.


From what I can tell Safari seems to interpret the `accept=&quot;video/*&quot;` attribute as `accept=&quot;*.mov&quot;` ignoring most, if not all, other video formats / extensions (webm, m4v, etc).

Any suggestions on how to get the select dialog to allow only common video filetypes (not just .mov&#39;s) in Safari?

Safari &lt;input type=&quot;file&quot; accept=&quot;video/*&quot;&gt; ignores mp4 files

I am trying to create an html5 web page in which there is a small video like 13s , I converted the flash version of this video into 3 format : .ogv using fireFogg , .webm using firefogg also and .mp4 using HandBrake application the html script I used in my page :
 
    &lt;video  width=&quot;800&quot; height=&quot;640&quot; loop preload=&quot;false&quot; autoplay  controls tabindex=&quot;0&quot;&gt;
      &lt;source src=&quot;xmasvideo/video.mp4&quot; type=&quot;video/mp4&quot; /&gt;
      &lt;source src=&quot;xmasvideo/M&amp;P-Xmas 2.ogv&quot; type=&quot;video/ogv&quot; /&gt;
      &lt;source type=&quot;video/webm&quot; src=&quot;xmasvideo/M&amp;P-Xmas.webm&quot; /&gt;
    &lt;/video&gt;
The video is working fine in Chrome and FireFox but not working at all neither in Safari on Desktop nor on iPhone or iPad , the output is simply a blank page that shows the controls of the the video tag but nothing is loaded

Note that the Safari version that I have supports HTML5 video



HTML5 Video tag not working in Safari , iPhone and iPad

I&#39;ve build a web page that let&#39;s you select a page name from a drop down list and then transfers the browser to that page.  The code that does the transfer is

    if (url){
        window.open(url, &#39;_blank&#39;);
    } 

where &quot;url&quot; is the page selected.

A console log just before the window.open line prints something like:

        executing: window.open(http://www.mywebsite.com/44/threats.html, &#39;_blank&#39;)

and then the browsers opens the page in a new tab.

This works fine on Windows 7 for all the browsers, including Safari.  

On an iMac it works for Firefox but not for Safari. 
 
Does anyone know why iMac/Safari won&#39;t do  this?




window.open(url, &#39;_blank&#39;); not working on iMac/Safari

On my last website, the text is perfect naturally on chrome and firefox without touching font-smoothing or anything else.   
But on Mac / Safari 7 the text appears well then turns immediately thinner (too much thinner / not nice to read).
![enter image description here][1]
![enter image description here][2]

After doing some research [cf http://www.usabilitypost.com/2012/11/05/stop-fixing-font-smoothing/]  
and some tests playing with 

    -webkit-font-smoothing    

It looks like Safari display the text first with :

    -webkit-font-smoothing: subpixel-antialiased;

Then just after you got the flickering effect, when it is turning font to :

    -webkit-font-smoothing: antialiased;



So it seems to me that I had no choice but to force 

    -webkit-font-smoothing: subpixel-antialiased;

to make my website consistent on all browsers.  
I am using font-face Avenir Std Roman.

Some explanations to that Safari problem ?
Any better solutions ?
Could my font be part of the problem ?

Thanks.
