Please forgive me if this question sounds like clearing Safari cache/cookies in General->Settings.
The issue is as follows:
We have a custom webpage where user can upload his profile icon/image by choosing from Phone's photo library or taking a photo.
The 1st time user uploads an image P1, it's uploaded successfully to server.
If user refreshes the webpage and tries to upload a different image P2, P1 is uploaded to server.
Problem persists even after clearing browser cache.
If I kill browser and clear cache, then I'll be able to upload a new image.
This problem does not occur on browsers on Google devices or on PC.
Somehow iPhone browser remembers the image object and I need to find a way to clear it.
Launch the Settings app from the Home screen of your iPhone or iPad.
Scroll down and tap on Safari.
Now scroll all the way to the bottom and tap on Advanced.
Tap on Website Data. Notice here you can see how much space on your iPhone or iPad website data is taking up.
Scroll to the bottom again and tap on Remove All Website Data.
Confirm one more time you'd like to delete all data.

I'm developing an app that works with sensitive information.
One of the requirements is that when a user puts the app in background the content that the app is currently displaying has to be hidden, so if another person navigate through the apps in background he can't see the last screen where the user was.
Any ideas on how to do that?
I tried to show an overlay when the app moves to AppLifecycleState.paused, but it doesn't work for me, the app prints a message if I want but it can't update the UI.
Edit
Shameless plug: i did a library for doing just that as I also needed it:
https://pub.dev/packages/secure_application
Answear
Build is not called after paused, at least on Android.
For Android I used a flutter_windowmanager package (modified to still be able to build on IOS):
https://github.com/neckaros/flutter_windowmanager
When my app need securing I add the flag secure:
FlutterWindowManager.addFlags(FlutterWindowManager.FLAG_SECURE)
And my app is now a black screen in the app switcher.
You should still hide content your way for when the user get back to the app.
Otherwise you can go native:

I'm working on a website that's optimized for mobile devices that can also be used on a desktop. In order to test the functionality of it without setting up a server, I'm using the iPhone simulator that comes with XCode. The website's purpose is to give a manager for the business a way of approving or rejecting potential offers the marketers have in mind to give to customers when they are away from their desk. When you get to the Approve/Reject page, you can click either the Approve or Reject button. Each button, once pressed will bring up a window (not a separate page) where the manager can add comments. On the iPhone simulator, whenever the window comes up, the iPhone will not let you scroll down at all on the window as, for some reason, the scroll function still seems to be connected to the main page, not the window that just came up. The problem only occurs on the iPhone part of the simulator, but not on the iPad part. I've been beaten by this problem for several days and I can't find anything on the internet that gives suggestions. Does anybody have any idea on what I should do with the coding, or if it's just what happens when you run the server locally on the simulator? Any help will be appreciated, as I've exhausted all I can think of.
Note: I'm using Ruby-on-Rails and the window that is popping up us a Bootstrap modal
Try Modal box on iPhone no scroll
The modal becomes a static height on the screen and it should allow you to scroll all the way to the bottom of that window.
Change the height setting so that it fits.
Im wrapping a html5 website in a native app. The app splash screen appears for a sec then a white page appears, I decided to add an image view that have the same image as the splash screen to fill this white screen and I hide this intermediate image once the websites download all the jquery and CSS. However, this screen lasts for really long time (up to 30 sec.) so I thought that it may be due to the jquery and CSS large buddle downloading time. So create a page which has and image and a redirect js(non library) statement and found that redirects so fast. I cannot understand why, anybody have an explanation
That's the expected behaviour when attaching a web view
You may want to consider that your app plans may run afoul of App Store guidelines:
Apple can reject mobile web shell apps.
I've always been able to get images into iphone simulator 3 by the usual methods described on this site (i.e. dragging image into iphone simulator).
However, having upgarded to the new xcode 3.2.3, although I can still save images to the simulator, I can't actually see them there when I go to the library on the simulator.
Thankfully - it works when I build for the iPad simulator.
Has anyone else go this problem or is my install of the new xcode screwy?
I've noticed that you can add them if you change the device in the Hardware menu. Switch to iPhone and do the usual. Then switch back to iPhone4 and you'll be able to see the images in the photo library.

You should also file a radar with Apple. ;-)
I was had the same problem after v4 upgrade but it seems to work if I drag the images into an album in the actual 'photos' app.
You can save images in the simulator by going to Safari on the iPhone,iPad.
Navigate to some URL eg, hot pictures of Megan Fox on google images. Click and hold on your favourite image of here, hopefully in a very hot pose. Then select save from the menu that appears.
This normally does it for me.
[UPDATED]
Sorry this does not work on 3.2.2 but has worked in the past.
Seems that you need to run the Photos app on the simulator after dragging in images in order for it to make the images available from your app.
First you simply run simulator then tap on back button after this drag image from your macbook u found small image on simulator screen hold courser on image
after a while bring a pop-up screenView on iPhone simulator screen to ask that you want to save this image or cancel
you just save and go back
open photo gallery you must be see one image in photo gallery
So I just made my web-application "iPhone Friendly". So you can add it to your home screen and it has an icon, no chroming, etc etc.
The problem is that I want to display a custom splash-screen every time it is opened from the iPhone home screen. Right now it just shows the last screen viewed while it basically runs a refresh.
I have tried attaching events to window.onfocus, window.onblur, window.onbeforeunload, and NONE of them seem to work right when the app is being run in "mobile-app" mode.
Am I being dumb? Er.... don't answer that. Does anyone know what is wrong?
Unfortunately, with the restrictions Apple imposes, this is impossible.
My recommendation is to create a App Store application with a full-screen WebView. Then, you can use a default.png file and a ImageView for your splash screen. Also, you get a ton more visibility on the App Store. (Also, if you go this route, check out PhoneGap - http://phonegap.com/).
Update!! In the iPhone 3.0 update, mobile safari now supports the ability to specify an image to be used on startup:
Remember this only works with iPhones that are running 3.0+
The loading screen you are talking about is the loading screen for an APPLICATION, not a webpage, i.e its the loading screen for Safari. This has nothing to do with "the restrictions Apple imposes", just with the fact that because your web app still runs in the browser, the browser needs to load first. Like was also said, if you want to get around this you need to build your own app, in which you can specify the splash screen.
Are you using this?
<meta name="apple-mobile-web-app-capable" content="yes" />
If yes, it should refresh every time when you exit the web app and enter again. It will NOT show the last screen viewed. Hence you can show your splash-screen every time when it is opened. In another words, you should show a full screen div / image every time when you load the page.
