I searched for this and couldn't find any references to this.
In my iOS universal app, I wanted to display the information icon (same as the utility application) at the bottom right of my main view controller and use the same both for iPhone and iPad to flip over to display information about my app and other things. On the iPadd Utility application template with XCode 4.6, the information icon is displayed as a button on the navigation bar and a UIPopOver control is used to display information.
In my case, I don't want to use a UIPopOver on the iPad but use the same flip over effect both for iPhone and iPad when clicking the information icon. Is this a valid as per Apple's guidelines or guaranteed for rejection?.
I do exactly what you're thinking of doing in my app. I used the flip transition to display my info page using the information icon as the button image. I had no problems with Apple regarding this when I submitted.

I have the next question. I am developing a react application with some images. The user has the possibility to click and open a full-page image. Because the image's orientation is horizontal on the mobile, it does not look good. My idea is when the user clicks on the full page icon, the orientation of the phone becomes horizontal as is implemented on youtube. I tried to find some information about that, but I am not sure if it is even possible, I saw that only by using react native and developing mobile applications you can have access to the user's orientation of the screen. But maybe there are some methods to do in the browser? Thanks in advance.
It is not possible to change this from the web, however you could simply rotate the image and display it full screen. This has been done here:
CSS Rotate Portrait Image 90 Degrees and Make Image Full Screen
The black screen is visible for a moment at the start of the app in android devices. I've tested in all of my recent apps and it is there. In some devices, the black screen appears a bit longer especially in oreo.
Have a look at the video here
How can I solve it?
This is triggered because your start method is taking too long to process the Form or the Form's rendering code is too slow. When that happens Android tries to draw your app but it takes too long and so it just shows what it has.
Remove the clutter from start and just show a Form that's a splash screen then transition to the actual app. Optimize your actual app UI by using profilers & the performance monitor tool.
In my opinion, showing a splash screen before the actual app (as suggested by Shai) is a good idea to be sure that all the splash screen images generated for iOS by the Codename One build servers are as you want them: in this way, the app startup look will be very similar on iOS and Android. Some popular app, like Facebook, use a splash screen that show their icon at the middle of the screen.
However, about your question, in my "new" Android 7 device, almost "all" the apps, even the ones preinstalled with Android, show a blank screen for a fraction of second at startup. So I suppose that it's normal. That blank screen is usually white, but is some app the color of the blank startup screen is different (for example, in ES File Manager is gray). Also my Codename One apps show a blank white screen at startup (before the splash screen in the apps in which I implemented it). Maybe the color of the startup blank screen depends on the styling of the app.
Lumia 730/735 have the on-screen navigation buttons, and this bar can be hidden/displayed using the swipe upward screen gesture. System apps correctly process the moment when this bar is hidden or displayed - they increase/decrease the height of their current page accordingly.
I have been developing a WP8 Silverlight app to manage checklists for 2 years. Recently I've obtained a Lumia 730 phone, and I'm testing my app on it. As I can see, some pages of my app does not fit the available screen size automatically. Look, for instance, at the following picture - I can't scroll a checklist to see the very last item when the navigation buttons bar becomes visible (the right screen):
As I understand, this happens because of some settings and non-standard page layout I use. My question is the following: how can I detect the moment when the visibility of the on-screen navigation buttons bar changes to correct the layout of my page from code?
Unfortunatelly, as far as i know, you cannot get any information about the bottom on-screen navigation status bar in Windows Phone 8. This is a good reason to develop a Windows Universal application. Propably this is what Microsoft wants from the developers.
I’m trying to deploy a CSS3-based horizontal navigation menu on a still-under-construction site I’m working on.
Hover or mouseover one of the menu’s titles and a drop-down menu appears. Move the mouse off of the title, or off of the list of dropdown items, and the menu collapses. So, the dropdown list of items stays open as long as it can ‘see’ the mouse pointer.
The menu features containers that allow for the presentation of content from the site, or even other sites. E.g., it can display images or entire webpages. I’m attempting to display an object created with Microsoft’s Silverlight platform. The object is embedded on another page of my site and, via php include, it plays well with the menu in all browsers I’ve tested it on … except Microsoft Internet Explorer 9. (Haven't tried IE10 yet.)
In the IE9 case, the Silverlight object appears as expected, but the dropdown menu collapses as soon as the mouse touches the displayed Silverlight object. I.e., the CSS3 menu loses sight of the mouse and the dropdown collapses the moment the mouse pointer touches the Silverlight object.
I haven't been able to find much in the way of help for this one.
Any thoughts or guidance are much appreciated. Thanks.
I want to make a javascript image gallery
(with 6 thumbnails in a row and as many rows as fit the page.
clicking the thumbnails will bring up a popup box with images and a video)
At the bottom of the page there is a numbered pagination.
However, I would like to make it so that on a mobile platform (android/iphone)
the user can paginate by swiping the pages to go forward or backward.
How do I adjust the pagination for a mobile platform?
Should I use a specific crossplatform tool like sencha to make this gallery?
Have you thought about using JQuery Mobile ?
