I am having a very weird issue on an iPhone and I would like to have suggestions on the best way to troubleshoot. My web application works fine for a moment then suddenly all text fields and buttons will have no effect, but only to open the virtual keyboard.
For example, a "delete" button which used to display a "yes/Cancel" modal will only make the keyboard open, the modal won't show up... When I reload the page, everything is working as expected again.
I am testing with an iPhone 6 and Chrome.
Did someone already encountered an issue like that?
I have absolutely no idea how to track down this behaviour and all suggestions are welcomed, What do you suggest I should look in priority?
This issue was coming from a bug in a version of Chrome I was using at that moment (I have no idea which one, since my phone has regular automatic updates).
I strongly advise to have always at lease two different platforms when testing websites!

I am making a Xamarin.Forms project, and I am in the end of my app, but something really strange have happened. My app starts up with no labels (!?), meaning they are invisible or not created at all. Everything else seems to be working, until I press a button that is supposed to change the label - when I do this, the app freezes. I get no exception in Visual Studio, though.
One problem is that my breakpoints in PLC code never hits, only those I place in the iOS code. However, the buttons not related to changing a label works, so I know the PLC code have been ran. If I let the app run for a little while, and then press the pause-button in VS debugging to see where in the code I am, it stops at
UIApplication.Main(args, null, "AppDelegate");
.. in Main.cs. I dont know if this is correct or not, when I run on Android, I get a Break Mode - No code is currently running.
I have been trying for hours to debug, reinstall, restart, clean and rebuild, but nothing seems to help. My code works perfectly in Android, and it worked in iOS 1 week ago. Anyone have any ideas what is going on, or what I can do to debug some more? Or must I make a new project and try start over?
Edit: I have also tried different starting pages, and all are the same: all views loads except those with text in them. I have a page with an Editor in it, and I can write in it, but no text is appearing inside of it. Only button have visible text. I do not use a custom font for my labels, I have not specified anything.
Waking up fresh in the morning, I found my issue in 15 minutes..
After altering my Google search to TextView iOS instead of Label Xamarin, I found much more answers. Thanks to this question and answer.
Basically, changing anything on the labels in the constructor of the page (even after InitializeComponent()), will mess up the view. I moved my code outside of the constructor (in the protected override void OnAppearing() method), and now it is working again.
The freeze part was not related - this was my custom menu that covered my screen with an invisible layout eating up all clicking events. A bit confusing, none of these issues are present in Android, but there you go.
This has been bugging me for several days with no solution in mind, when I tried tapping on any input fields in iOS safari, it literally takes a minute before the keyboard pops up.
I have tried everything, setting the viewport, disabling zoom, removing all the extra javascript to the bare minimum, still it is happening. Strangely this does not happen when I tap on a textarea, only on text input.
Does anyone have any idea what would cause this?
Okay I just found the solution. Apparently safari on iOS will act wonky when you are running https without a proper certificate. Once I signed the certificates for my subdomains everything appears to be silky smooth now. It's really weird, as I do not expect https to affect form elements in the website.
This is a quite strange behavior that 'persecutes' me since iOS 7.0 :) I hope someone of you can help me this time! As you probably know when you are using VoiceOver your gestures are totally different from the 'normal way'. When you need to bypass VoiceOver for a specific view you can set its accessibility traits as UIAccessibilityTraitAllowsDirectInteraction. When the view has this parameter set the user can interact with it as usual (like VoiceOver is not active in that particular view).
Quite often happens that this ability is randomly lost so VoiceOver acts in its normal way.
Did anyone of you encounter this problem in its experience? Did he solve it? Fortunately turning off and on VO seems to temporarily solve this issue (until next time it happens again)
Any idea? Thank you very much
I've seen this with other things as well. For example, notifications can be spotty, particular Screen Changed or Content Changed notifications. I believe this happens as a result of turning VoiceOver on and off. For example, if you were to turn VoiceOver on, leave it running, and open your application as a user would, you would never experience these issues.
However, if you use the VoiceOver shortcut. Or interrupt the application, re-install, and restart while using Xcode, you can disrupt the VoiceOver's connection to the application. It doesn't bond correctly. So, simple things like navigation work fine. But advanced features like notifications (and perhaps some of the more complicated traits) don't work.
Essentially, I would classify this as a bug, but a bug that only shows itself when you use VoiceOver in a way that only a developer would use it.
I'm experimenting with different techniques using Amazium here http://stevengeorgeharris.com/croft/croft; when viewing on an iPad the image of the ballet dancer is missing, yet appears on everything else including Nexus 7 and iPhone 5. I have played around with positioning and z-index's but nothing happens.
I then went into IOS simulator to use web inspector and I noticed when I refresh the page the image appears and quickly disappears again. I cannot for the life of me find the cause of the problem, maybe I am over looking something very simple, as I usually do.
Change position:relative to position:absolute for it to show up on iOS.
i just see the website try to add overflow:hidden it will be good in regular explorer but it will not work in iOS but look nice
I'm making a web project that is fitted to the iPad screen. I'm trying to make it look as much like a native app as possible. It is loaded in safari or atomic browser. What I'm trying to find out is if it's possible to eliminate the drag and even the zoom functions of one of those browsers for just that site.
To rephrase, I want to make my site fixed on the screen at all times. The issue is, a user will try to hit a button and it will drag the screen.
PS. An additional question is how I can make it so images don't have the "save as" functionality if held down I tried putting a span over the images, and that worked for firefox, but not iPad safari.
If you can solve any or all of these, you would have my biggest thanks!
Turns out that there are several metatags that you can put in your js file which keep the screen fixed. Good stuff on that is here:

As far as the "save as" issue, I don't know yet, that part of my app development hasn't been solved.
